3 September 2026 — EOD read. The tape did in one session what it had been refusing to do for three: SPY closed at 773.17, up 1.05% (+8.01 versus 765.16), and it closed within a dollar of its high. Underneath, the options tape was not merely willing but insistent. Net call premium finished at +$467M against −$61M of net put premium, roughly four times Tuesday’s reading, and nine of the eleven contracts this desk flagged yesterday came back this morning as real open interest. The regime line moved with it, crossing from Neutral into Bull · early.

Market-wide net call premium through the session ($M). Net put premium closed at −$61M.

Wednesday’s radar — OI confirm

Contracts flagged 2 Sep, checked against 3 Sep’s open-interest update

SPY Sep 11 $760 puts	44,705	37,859 → 37,267 (−592)	—	Not confirmed

Nine of eleven is the second clean sweep in as many sessions, and the two failures are as informative as the nine. The SPY September $760 puts carried 44,705 contracts of volume yesterday and finished today with 592 fewer open contracts than they started with. That was a position being closed, not opened. The same is true in miniature of the TSLA January 2027 $370 calls, where 1,902 lots produced sixty contracts of new interest. Everything else held: both DELL long-dated call lines converted almost their entire volume into open interest, and the SPX September 7680 straddle we flagged on Tuesday now sits on the books with both legs confirmed.

What happened

The session never traded below its open. SPY started at 767.90, set its low at 767.45 inside the first minutes, and spent the remaining six hours grinding to a 774.03 high before closing at 773.17. QQQ ran the same shape and finished up 1.19% (717.67 versus 709.24). Market-wide options volume ran 42.6M calls against 30.6M puts for a 0.72 put/call, with $23.72B of call premium against $17.36B of put premium.

The tide is where the conviction shows. Net call premium crossed +$193M by 10:30 and +$360M by 11:30, then held a plateau through the early afternoon before peaking at +$476M just after 14:00. It closed at +$467M. Net put premium spent the entire afternoon negative, finishing at −$61M. Tuesday’s equivalent reading was +$124M. Whatever was buying today was buying with both hands, and it did not fade into the bell.

Volatility gave up ground. VIX traded a 14.23 to 15.44 range against Tuesday’s 15.12 to 16.82. The vendor’s closing row again printed a close below the session low, so the strip carries the range rather than a close. Either way the direction is unambiguous.

Why it matters

A 1% up day with a four-fold jump in call premium and a confirmed radar is a coherent signal, and coherence has been the missing ingredient for a fortnight. The regime line agrees: MPI held at 65 but its published label crossed from Neutral into Bull · early on the 2 September bar. That is the first Bull-family read this desk has published since the August drawdown, and it is scored in the Ledger like everything else.

One caution belongs in the same breath. The largest options prints on the tape today were not opinions. Four SPX legs of roughly 5,000 lots each printed inside the same millisecond cluster at the 7000 and 8000 strikes for December, with matching call and put sizes, and the pattern repeats at 7750, 7755 and 7760 for September. Matched sizes at matched timestamps across both sides of the same strike is the fingerprint of box and conversion financing, not of a view. Strip those out and the genuinely directional flow of the day was smaller, and rather more defensive than the index tape suggests.

What to watch into Friday’s session

• SPY 774.03 is today’s high and the first level since the drawdown that the tape has closed within a dollar of. A close above it extends the sequence.
• SPY 767.45, today’s low and the open, is the floor that was never tested twice.
• QQQ 718.92 and 709.69 are the equivalent brackets.
• VIX 14.23 is the session low. Sustained trade under 15 keeps the vol fade intact.
• The SNDK $1390 call line expires 11 September and printed 1,144 contracts against open interest of 11. Tomorrow’s open-interest update settles whether that was positioning or a day trade.
• Net call premium above +$400M for a second session would make today a trend rather than an event.

Names on our radar

Every row below is frozen at publication and scored mechanically in the Accountability Ledger at +5 and +21 sessions — misses stay on the page. Options prints are checked against the next morning’s open-interest update in the following session’s post.

Ticker	What printed	Read
SNDK	Sep 11 $1390 calls, $8.5M at 100% ask-side across 58 trades, 1,144 lots against open interest of 11	Volume at 104 times open interest, eight days from expiry, paid at the offer. The storage complex keeps drawing aggressive money.
SPXW	Sep 30 $7525 puts, $37.0M, 12,042 lots against open interest of 828	The largest genuinely one-sided index print of the session, struck roughly 3% below spot.
AMD	Jan 2027 $460 puts, $8.2M sweep, 80.3% bid-side, 1,592 lots against open interest of 1,441	Long-dated downside sold rather than bought. A different posture from the SNDK buyer in the same complex.
SPXW	Oct 7 $8000 calls, $4.5M on descending fills, 4,214 lots against open interest of 17	The highest volume-over-open-interest ratio on the screen at 248 times. Small dollars, very loud footprint.
QQQ	Oct 2 $700 puts, $4.0M at 100% bid-side, 5,180 lots against open interest of 1,305	Near-dated index protection sold into strength on the day the index gained 1.19%.
IWM	Oct 16 $285 puts, $3.5M sweep at 100% bid-side, 9,734 lots	Small-cap downside sold in size. Pairs with the QQQ line rather than against it.
WDC	Jun 2027 $420 puts, $4.2M on descending fills, 486 lots against open interest of 133	The other half of the storage trade, and the only far-dated put accumulation on the board.

The set-up

September’s second full session produced a clean up day, a four-fold expansion in call premium, a regime label that crossed into Bull · early, and a radar that confirmed nine times out of eleven. Against that sits a dark-pool board where 42% of the money went into four index vehicles and where the leveraged, inverse and volatility complexes printed nothing at all above $100M. The market went up and the hedging machinery went quiet. Friday tells us whether that was conviction or simply the absence of sellers.

The boards — data appendix

92 prints across 58 names, complete $100M+ universe

Boards are computed on the complete universe of dark-pool prints of $100M or more for the session: 92 prints across 58 distinct names, $23.34B in total notional, pulled by descending premium until the screen was exhausted (93 raw rows, 1 canceled print dropped, 0 vendor duplicates).

Board	Today’s read
Participation	$23.34B across 92 prints in 58 names. ETFs 38 prints / $12.62B (54% = 12.62/23.34); single names 54 prints / $10.72B (46%). No trailing baseline is available from this cloud desk yet, so no average comparison is offered. The raw split is the read.
Concentration	Technology carried 38.8% ($4.16B of $10.72B) of single-name dollars. Top single name META at $1.06B, 9.9% (1.06/10.72) of all single-name notional, in two prints at the same 610.68 mark.
Positioning gauge	Leveraged-long $0 · inverse $0 · volatility-linked $0 on the ≥$100M board. A second consecutive session with nothing in the hedge vehicles. $0 is information.
Threshold count	92 prints at or above $100M. The index complex (IVV, VOO, SPY) absorbed $9.90B, 42% (9.90/23.34) of the entire board. QQQ printed nothing at or above $100M today.

Cluster watch

Same name, same price, multiple prints. That is the fingerprint of one program working an order. Top three by aggregate notional, of fourteen clusters detected at ±0.1%:

Ticker	Price	Prints	Aggregate	Window ET
IVV	~$776.21–776.85	5	$3.93B	12:16 PM – 4:30 PM
VOO	~$710.67–710.71	4	$3.11B	12:20 PM – 4:11 PM
SPY	~$773.11–773.17	7	$1.57B	4:00 PM – 5:43 PM

Also clustered: META 2 prints, $1.06B at 610.68; UNH 4 prints, $728M at 400.94; LLY 3 prints, $699M; NVDA 2 prints, $614M at 228.45; SNDK 2 prints, $320M at 1,554.99. Four of the five heaviest clusters land inside two narrow windows, one at 4:00 to 4:06 PM and one at 5:06 to 5:07 PM. That timing is consistent with closing-auction and basket work rather than fourteen independent decisions.

Notable data points

1. $23.34B in dark-pool prints of $100M or more, across 92 prints and 58 names, with one canceled print dropped.
2. The index complex (IVV, VOO, SPY) absorbed $9.90B, 42% of the board. QQQ printed nothing at that size.
3. Net call premium closed at +$467M against −$61M of net put premium, having peaked at +$476M just after 2:00 PM.
4. Market-wide put/call 0.72 (30,602,283 puts / 42,619,299 calls); $23.72B call premium against $17.36B put premium.
5. META was the largest single name at $1.06B in two prints, both marked at 610.68.
6. Leveraged-long, inverse and volatility ETFs printed $0 above the $100M threshold for a second session.
7. Nine of eleven flagged contracts confirmed in open interest, an 82% rate. The two failures both showed volume without new interest.

Method note

Flow and dark-pool data sourced from Unusual Whales. MPI score and regime classifier are our internal composite; daily synthesis is AI-assisted from those inputs.

Volume-over-OI activity is unconfirmed as new positioning until the next morning’s open-interest update; confirmations are published in the following session’s post. Board baselines are trailing-session averages computed from our own archived pulls; derived indicators are computed by AZTMM from licensed market data.

Degradations disclosed for this edition. The vendor’s VIX closing row again printed a close (14.00) below the session low (14.23), so the strip carries the 14.23 to 15.44 range instead of a close. The options-flow screen returned the fifty largest alerts of the session rather than every alert above $1M, so its effective floor was $3.06M and the sample is top-of-book by premium. Bid and ask side percentages were absent on all forty SPX and SPXW repeated-hit rows, so no side skew is claimed for them. One flow row (DLLL) carried a market capitalisation field inconsistent with a $5M print and was excluded rather than published. The MPI strip is dated 2 September because the pipeline finalises each day’s bar overnight.

2 September 2026 — EOD read. The quiet +0.44% (765.16 vs 761.78) on the SPY tape undersold this session. Underneath it: the single best open-interest confirmation morning this desk has printed — eight of ten contracts from Tuesday’s radar came back as real new positioning, none failed — a $20.65B dark-pool board dominated by month-start index blocks, a memory complex that will not cool off, and the SPX Jan-2027 8000-call buyer showing up for a third consecutive session. Four earnings reports landed after the bell. Thursday opens loaded.

Market-wide net call premium through 2 Sep, as reported in the session narrative ($M)

The boards

73 prints across 46 names, complete $100M+ universe

Boards are computed on the complete universe of dark-pool prints of $100M or more for the session: 73 prints across 46 distinct names, $20.65B in total notional, pulled by descending premium until the screen was exhausted (75 raw rows, 2 vendor duplicates dropped, 0 canceled prints).

Board	Today’s read
Participation	$20.65B across 73 prints in 46 names. ETFs 34 prints / $12.19B (59% = 12.19/20.65); single names 39 prints / $8.45B (41%). No trailing baseline is available from this cloud desk yet, so no average comparison is offered — the raw split is the read.
Concentration	Technology carried 58% ($4.91B of $8.45B) of single-name dollars. Top single name NVDA at $1.64B — 19% (1.64/8.45) of all single-name notional by itself.
Positioning gauge	Leveraged-long $0 · inverse $0 · volatility-linked $0 on the ≥$100M board. After Monday’s heavy SQQQ call print — which, note, confirmed in OI this morning — the hedge-vehicle tape went silent today. $0 is information.
Threshold count	73 prints at or above $100M — a heavy session, swollen by the index complex: IVV + VOO + SPY + QQQ block dollars total $10.04B, 49% (10.04/20.65) of the entire board.

Cluster watch

Same name, same price, multiple prints — the fingerprint of one program working an order. Top three by aggregate notional (of twelve clusters detected at ±0.1%):

Ticker	Price	Prints	Aggregate	Window ET
IVV	~$768.64	6	$4.50B	11:55 AM – 4:25 PM
VOO	~$703.20	4	$3.01B	11:13 AM – 4:08 PM
SPY	~$765.00	5	$1.90B	4:09 PM – 4:59 PM

Also clustered: NVDA — 4 prints, $1.64B, every one at exactly $224.41, the closing price; SNDK — 3 prints, $899M at $1,553.40; WMT $910M in 2; INTC $557M in 2 at $90.05. When three S&P-tracking vehicles absorb $9.4B at their marks on the second session of the month, that is calendar money being put to work, not a directional bet — but its size tells you how much cash showed up to start September.

What happened

The session had one texture from mid-morning on: steady bid, puts for sale. SPY opened at 762.45, tagged its 761.73 low in the first hour, and never looked back — closing 765.16, up 0.44% (+3.38 vs 761.78), in the top quarter of a 761.73–766.43 range. QQQ added 0.23% (709.24 vs 707.64). The market-wide options tape ran 35.6M calls to 25.1M puts — a 0.70 put/call — and the net premium tide, after one brief put-positive wobble around 9:50–10:00 AM, spent the entire day building: net call premium crossed +$40M by 10:15 AM, +$77M by 3:00 PM, and finished at +$124M with net put premium at −$33M. The buying accelerated into the close rather than fading — the last 90 minutes were the strongest stretch of the day.

The engine was the memory-and-AI-hardware complex. NVDA rose 3.21% (224.41 vs 217.44, high 227.95) on options volume of 3.60M calls — 1.57× its 30-day average (3,603,522 vs 2,290,227) — with net options premium of +$64.2M, and $1.64B of dark-pool notional in four prints, all marked at the close. SNDK printed $899M of blocks at $1,553.40 while MU sits at $956 — the memory supercycle trade kept writing itself. DELL saw $154M print at $492.20 late in the day alongside far-dated call buying (more below). Against all that, VIX faded from an early 16.82 high to a 15.12 session low; the vendor’s closing row failed our sanity check (printed close below the session’s own low), so the strip carries the range — either way, volatility ended the day lower against Tuesday’s 16.00 close.

One counter-current worth naming: SPY’s own options tape leaned defensive — 4.97M puts to 4.02M calls and net premium of −$22.5M on the day. Hedging into a rising tape is not bearishness; it is what accounts do when they add exposure and insure it in the same breath. The index put buying below sits in the same category.

Tuesday’s radar — OI confirm

Contracts flagged 31 Aug & 1 Sep, checked against 2 Sep’s open-interest update

Every options print we flag is checked against the next morning’s open-interest update — volume can be day-traded away, open interest cannot. This morning’s update covered the ten contracts from the combined 31 August & 1 September edition. The result is the cleanest sweep this desk has recorded: eight confirmed, two partial, zero not confirmed. Ratio = next-day OI change ÷ prior-day volume; ≥0.40 Confirmed, 0.10–0.40 Partial.

Contract	Prior vol	OI change	Ratio	Verdict
SPY Nov 30 $684 puts	18,824	15 → 18,827 (+18,812)	1.00	Confirmed
SPXW Oct 2 6900 puts	7,794	284 → 7,959 (+7,675)	0.98	Confirmed
SNOW Sep 11 $327.50 calls	625	36 → 649 (+613)	0.98	Confirmed
SQQQ Sep 18 $37 calls	8,210	6,814 → 14,775 (+7,961)	0.97	Confirmed
AGX Sep 18 $410 calls	1,088	24 → 1,047 (+1,023)	0.94	Confirmed
ANET Jan 2028 $190 puts	909	76 → 907 (+831)	0.91	Confirmed
MU Sep 9 $960 calls	1,480	78 → 1,072 (+994)	0.67	Confirmed
SPX Jan 2027 8000 calls	2,064	25,574 → 26,849 (+1,275)	0.62	Confirmed
SPY Oct 16 $725 puts	55,084	26,504 → 37,392 (+10,888)	0.20	Partial
TSLA Jan 2027 $380 calls	5,171	4,405 → 5,027 (+622)	0.12	Partial

Read that top row again. The SPY November $684 put line went from 15 open contracts to 18,827 — the entire day’s volume settled as new open interest, a 1.00 ratio on an 18,824-lot day. The October 2 SPXW 6900 puts did nearly the same (0.98). These were not noise; someone built real downside protection Monday and Tuesday, and it is on the books. On the other side, the SQQQ September $37 calls more than doubled their open interest (+117% = 7,961/6,814) — the inverse-QQQ position was held, not flipped. And the SPX January 2027 8000 calls added 1,275 contracts of fresh OI on top of a 25,574-contract base — then, today, the same line traded another 8,234 contracts with two more repeated-hit sequences totaling $33.5M at ~$149 per contract. Three sessions running, same strike, same direction, still accumulating.

Why it matters

A confirmation sweep like this morning’s changes how much weight the radar deserves. When 10-of-10 flagged prints become open interest — 8 at conviction size — the tape is telling you the big-money flow you watched was positioning, not churn. And the shape of what confirmed is the story: heavy, dated index puts (November SPY, early-October SPXW) alongside a long-horizon upside call position in SPX and a doubled inverse-QQQ line. Large accounts are bracketing — owning the melt-up through January 2027 while paying up for insurance against an autumn air pocket. Today’s fresh flow extended the same architecture: a $24.8M both-sides structure at SPX 7680 for September 18 (calls $12.5M, puts $12.3M — a bet on movement, not direction, pinned to triple-witching), another $21.7M of October 7600 puts, and the third day of 8000-call accumulation. With MPI at 65 in a Neutral regime, this is what a market that expects to move — but hasn’t picked a direction — looks like in the flow.

What to watch into Thursday’s session

• AVGO, HPE, SNOW and AGX all reported after today’s close — results were landing as this went to press, and Thursday’s open prices the reactions. Yesterday’s SNOW $327.50 calls and AGX $410 calls confirmed into those prints; the scoreboard on that positioning arrives at the open.
• SPY 766.43 — today’s high and the ceiling of this three-day grind. A close above it puts the tape back at highs; 761.73, today’s low, is the floor that held.
• QQQ 709.80 / 705.10 — the equivalent brackets, with the 3-print $707.65 dark-pool cluster sitting right inside them.
• NVDA 227.95 — today’s intraday high. The stock gave back $3.54 from that high into 224.41; whether that gap closes or widens Thursday says how much of today’s 1.57× call volume had follow-through behind it.
• VIX 15.12 — the session low. Continued closes under 16 keep the vol fade intact; the $24.8M SPX 7680 straddle money is betting that calm breaks by September 18.
• SPX 7680 — the strike where today’s biggest two-sided money planted its flag, 0.5% above the 7645 spot reference on the prints.

Names on our radar

Every row below is frozen at publication and scored mechanically in the Accountability Ledger at +5 and +21 sessions — misses stay on the page. Options prints are checked against the next morning’s open-interest update in the following session’s post.

Ticker	What printed	Read
SPX	Jan 2027 8000 calls — two repeated-hit sequences, $33.5M total ($18.6M + $14.9M) at ~$149, 10,234 traded vs 26,849 OI	Third consecutive session in the same line, and yesterday’s tranche confirmed in OI this morning. The most persistent single position on our board.
SPX	Sep 18 7680 calls AND 7680 puts — $12.5M calls, $12.3M puts, matched sequences at the same strike	A $24.8M both-sides structure pinned to triple-witching, struck 0.5% above spot. Movement bet; direction agnostic.
SPX	Oct 16 7600 puts — $21.7M in two sequences ($12.1M + $9.6M), 2,250 contracts	Fresh October downside on top of the November/October put wall that confirmed this morning. The insurance book keeps growing.
SPXW	Sep 11 7825 calls — $1.1M, 2,500 lots, volume 9.05× open interest	Short-dated upside 2.4% above spot with the week’s heaviest volume-over-OI print. Small dollars, loud footprint.
SPY	Sep 11 $760 puts — $1.0M sweep, 94% ask-side (949,613/1,009,903), ascending fills	Urgent near-dated protection struck at today’s support shelf. Pairs with the index hedge theme, not against it.
AVGO	Oct 16 $370 calls — $1.8M ask-side, volume 1.8× OI, hours before tonight’s report	Same strike showed OI shrinking after Friday’s chase — that money day-traded it. Today’s buyer went in anyway. Tomorrow’s OI update settles who held.
MU	Sep 9 $950 puts — $2.3M traded entirely at the bid, volume 12.6× open interest	Puts hit on the bid are being sold, not bought — someone writing near-dated downside 0.6% under a $956 stock. After yesterday’s $960 calls confirmed, the flow around MU stays constructive.
DELL	Jun 2027 $620 and $720 calls — $1.4M + $1.1M, volume 4.3× and 7.5× OI, plus a $154M dark-pool block at $492.20	Far-dated, far-OTM upside laddered 26–46% above spot on a day the stock ripped. Someone is underwriting a much bigger DELL.
TSLA	Jan 2027 $370 calls — $2.9M in two repeated-hit sequences (1,433 + 1,883 traded vs 3,627 OI)	Yesterday it was the $380s (partial confirm, +14% OI); today the buyer stepped one strike closer. Walking the position in, not chasing.

The set-up

September opened with $10B of index blocks marking calendar money in, a one-way call tide, and a leadership complex — NVDA, memory, AI hardware — that printed institutional size all day. Over it hangs the most complete hedge structure we’ve tracked this quarter, now confirmed in open interest rather than inferred from volume. Four postmarket reports are already in the tape for Thursday. The regime tab says Neutral at MPI 65; the flow says both tails are being paid for. Sessions like this are why the radar exists — when the market finally picks its direction, the positioning that was built in the dark will have told you first.

Notable data points

1. $20.65B in dark-pool prints of $100M or more — 73 prints, 46 names, zero canceled.
2. The index complex (IVV, VOO, SPY, QQQ) absorbed $10.04B of it — 49% (10.04/20.65) of the board.
3. NVDA: $1.64B in four prints, every one at the $224.41 close; 3.60M calls traded, 1.57× its 30-day average; net options premium +$64.2M.
4. SNDK: $899M in three prints at $1,553.40 — the memory complex (MU $956) keeps drawing block money.
5. GBTG: a single $103.8M print of 10,999,021 shares at $9.44 — roughly 8.9× the stock’s entire average daily volume in one trade.
6. Market-wide put/call 0.70 (25,077,124 puts / 35,593,443 calls); $16.92B call premium vs $11.00B put premium.
7. Net premium tide finished at +$124M calls / −$33M puts, with the strongest accumulation in the final 90 minutes.

Method note

Flow and dark-pool data sourced from Unusual Whales. MPI score and regime classifier are our internal composite; daily synthesis is AI-assisted from those inputs. Volume-over-OI activity is unconfirmed as new positioning until the next morning’s open-interest update; confirmations are published in the following session’s post. Board baselines are trailing-session averages computed from our own archived pulls; derived indicators are computed by AZTMM from licensed market data. Today’s specifics: the vendor’s VIX closing row printed 15.00 against a 15.12 session low and failed our sanity check, so the strip carries the session range (15.12–16.82) instead of a close; the flagged-events screen reflects the 50 most recent qualifying events of the session at $1M+ premium; the ≥$100M dark-pool universe is complete via premium-descending pagination with duplicate vendor rows removed; no trailing board baseline exists yet on this desk’s archive, so boards state raw values without average comparisons; MPI 65 is the latest published value (as of 1 September) — the pipeline finalizes each session’s bar on its overnight recompute, and the strip freezes at publication.

Combined edition, covering Monday 31 August and Tuesday 1 September. The desk publisher was offline both sessions; the automated fallback posted condensed snapshots each evening, and tonight’s has been upgraded in place to this full edition under the desk’s standing repair rule. Monday’s condensed post stays as published. Nothing here is backdated — every number below was pulled tonight and is labeled with the session it belongs to.

The boards

Boards are computed for Tuesday 1 September only, on the universe this run resolves completely: every off-exchange print of $100M or more — 89 prints, $20.6B aggregate, after removing one canceled print and three duplicate vendor tracking IDs. Nothing below is estimated.

Participation. Names printing $100M+ dark-pool blocks Tuesday: 53 — 30 single names carrying $11.1B and 23 ETFs/trackers carrying $9.6B. That is a flip from Friday’s session, when trackers out-weighed single names $11.4B to $8.4B. The trailing-session baseline file was not available to this run, so no average comparison is published.

Concentration. Leading sector by aggregate notional among single names: Technology, $5.78B across 23 prints — NVDA alone carried $1.93B, a third of the sector’s total. Communication Services followed at $1.97B, Financial Services at $1.54B.

Positioning gauge. Leveraged-long ETFs: one SSO block, $211.2M, on the dark-pool side. Inverse/bear ETFs: $2.46M of SQQQ call premium on the flagged-options side. Volatility ETFs: $0. Threshold counts. Dark-pool prints of $100M or more: 89 (complete count). The flagged-options screen returns its 50 most recent $1M+ events for the session — 5 carried sweeps, 45 were block or repeated prints; a full-day total is beyond this run’s screen depth and is not published.

Ticker	Price	Prints	Aggregate	Window (ET)
SPY	~$761.5–761.8	8	$2.55B	3:42–5:10 PM
NVDA	$217.44	3	$1.60B	4:00–5:05 PM
MSFT	$501.02	5	$1.43B	4:00–5:42 PM

Cluster watch: fifteen repeated-price clusters printed Tuesday. The standout is not any one of them but the stamp they share — at 5:05:04 PM, five separate prints crossed within one second, in NVDA, GOOG, GOOGL, MSFT and SPY, each engineered to almost exactly $500M. The same ~$500M-per-name basket pattern printed Monday at 4:54–4:55 PM in MSFT, GOOG, GOOGL and NVDA. Program-sized, price-agnostic, two closes in a row.

What happened — Monday 31 August

Monday was quiet on the surface: SPY eased 0.30% to $767.05 — closing almost exactly on the $767 floor Friday’s edition flagged — and QQQ finished flat at $716.76 (+0.05%). NVDA bounced 1.48% to $220.78, recovering part of Friday’s fade. The index options tape stayed defensive even in the calm: SPY’s put/call ran 1.22 and QQQ’s 1.23, both heavier than Friday. VIX spent Monday’s session between 14.86 and 15.48; the vendor’s Monday closing print failed the range sanity check and is not republished (see Method note). Off-exchange, month-end was visible everywhere: a $1.27B IVV average-price cross, two $1.15B SPY prints at the same $766.86 average price, an engineered $1.0B SPYM print, $713M in ITOT, and the 4:55 PM basket crosses noted above — classic index-fund tape into the August close.

What happened — Tuesday 1 September

September opened with the break. SPY fell 0.69% to $761.78 — decisively below the prior week’s $767–$768 floor — after ranging $759.48–$764.67, and QQQ dropped 1.27% to $707.64, its first close under the $715 line Friday’s edition marked. NVDA gave back Monday’s bounce (−1.51% to $217.44, a two-day round-trip to almost exactly Friday’s close), MRVL slid further to $210.39, and AMZN — down 4.3% over the two sessions to $254.92 — was the big-cap casualty of the stretch. VIX printed a 16.00 close, up from the low-14s regime that held all of last week. Market-wide options volume ran 34.3M calls to 29.8M puts — a 0.87 put/call ratio, sharply heavier than Friday’s 0.74 — with $18.9B in call premium against $16.5B in puts. SPY’s own put/call came in at 1.18, QQQ’s at 1.21, and SPY’s net options premium finished at −$20.8M.

Friday’s radar — OI confirm, two sessions late

Friday’s flagged prints, checked against the latest open-interest data — which reflects positioning settled through Monday (Tuesday’s trading settles into tomorrow’s update). Because the desk missed two sessions, this is a cumulative two-session check against each contract’s open interest at flag time, not the usual overnight read. Thresholds: net OI growth ≥40% of flagged volume = confirmed; 10–40% = partial; under 10%, or OI down = not confirmed.

Contract	Flagged Friday	OI since flag	Verdict
AVGO Sept 4 $370 calls	~$11.4M, three bursts, volume past OI	11,371 → 5,892 (−48%)	Not confirmed — OI fell
NVDA Sept 4 $225 calls	~$5.7M, 94k contracts churned, bid-tilted	60,417 → 38,603 (−36%)	Not confirmed — net closing
MRVL Sept 18 $220 calls	$1.09M ask-side after the earnings gap	3,607 → 3,792 (+5%)	Partially confirmed — marginal
AMZN Sept 4 $267.50 puts	$1.63M ask-side, volume 49x OI	164 → 794 (+384%, but 8% of flagged volume)	Not confirmed — mostly day-traded
IWM Sept 18 $286 puts	~$4.5M, two bursts	87,533 → 77,501 (−11%)	Not confirmed — OI fell
SPX Jan 2027 8200 calls	$15.3M, minute-paired with the 7000 puts	4,607 → 8,240 (+79%); a further 3,500-lot ask-side block ($31.0M) added Monday	Confirmed opening
SPX Jan 2027 7000 puts	$13.5M, the other half of the pair	48,196 → 47,410 (−1.6%)	Not confirmed — flat
HPE Jan 2027 $46 puts	$1.75M at the bid, volume 2x OI	1,813 → 5,510 (+204%; ~100% of flagged volume became OI)	Confirmed opening
ADBE Sept 2027 $350 calls	$1.25M, volume 46x a 7-contract base	Row not returned by the OI screen	No data
POWL Feb 2027 $240 calls	$3.06M floor print, ask-side	2,587 → 1,744 (−33%)	Not confirmed — OI fell

A rougher card than Friday’s, and it stays on the page: two confirmed, one marginal, six not confirmed, one no-data. The confirmations are telling — the HPE pre-earnings put book is real (virtually every flagged contract became standing OI, with the report due Wednesday), and the SPX January call wing kept building while its paired put leg went flat. The misses are telling too: both Sept 4 weekly-call stories — AVGO and NVDA — resolved as churn, not positioning, and the NVDA row answers Friday’s open question directly: the bid-tilted fills were the sellers. One nuance the scoring doesn’t capture: the AMZN $267.50 puts mostly day-traded away, but the residual line is nearly five times its pre-print base and finished the stretch deep in the money with AMZN at $254.92. Every verdict lands in the Accountability Ledger.

Why it matters

Our read: the character of the index put tape changed on Tuesday. Last week’s hedging was methodical — near-the-money strikes, laddered expiries, rolls. Tuesday’s flagged tape added something different: $7.7M of premium into SPY November 30 $684 puts — ten percent out of the money, against fifteen contracts of standing open interest — plus $8.2M into SPXW October 6875/6900 puts nine percent below spot, four separate flagged bursts on the SPY October $725 line, and $2.5M of SQQQ calls. Deep-strike, longer-dated, opened from near-zero bases: that is tail-risk buying, not maintenance hedging. It arrived on the same session the S&P broke its floor and the VIX left the 14s — and, for symmetry, the upside was not abandoned: a single $26.7M burst printed in SPX January 2027 8000 calls, and the January 8200 call wing has now grown 79% since Friday’s flag.

The model agrees with the tape. Friday’s edition (28 August) published our regime read as Bull with MPI 71; tonight the classifier reads Neutral with MPI 67, as of Tuesday’s close, with the model’s sideways-state probability at 67%. That flip is published here exactly as the framework produced it and is scored in the Accountability Ledger like every other read — no re-narration of Friday’s stance. Two closes below the prior week’s floor, a VIX regime change, tail-strike accumulation, and a classifier downgrade, set against a still-orderly tape (two-day SPY damage totals just under 1%) — that is the tension Wednesday’s earnings slate walks into.

What to watch into Wednesday’s session

• $759.48 — Tuesday’s SPY low, and the level to watch. A close below would extend the break to a second lower low; $767 — last week’s floor, now overhead — is the reference on the other side.
• $704.66 — QQQ’s Tuesday low, with $715 now the overhead reference after the first close beneath it.
• Wednesday postmarket is loaded: AVGO, HPE, SNOW and AGX all report after the close — each carries flagged positioning from the last two editions (HPE’s confirmed $46 puts, SNOW’s $327.50 calls, AGX’s floor-printed calls, and what remains of AVGO’s $370 line).
• VIX at 16.00 — the first close out of the 14s since last week; a settle back under 15 would mark the move as a one-session spike, a hold above 16 would not.
• NVDA closed $217.44, within eleven cents of Friday’s close after a full round trip; $215.10 (Tuesday’s low) is the nearest reference below.
• The MU September 2 $940 puts flagged Tuesday expire Wednesday — the shortest-dated print on the radar, worth watching purely for how it settles.

Names on our radar

Every row below is frozen at publication and scored mechanically in the Accountability Ledger at +5 and +21 sessions — misses stay on the page. Options prints are checked against the next morning’s open-interest update in the following session’s post.

Ticker	What printed	Read
SPY	$7.7M across two ascending-fill bursts at the Nov 30 $684 put; 18,800 contracts against 15 of standing OI, ask-side led.	Ten percent out of the money, three months out, opened from nothing — the day’s clearest tail-hedge print.
SPY	Four flagged bursts at the Oct 16 $725 put, ~$4.7M combined; volume 2x OI, fills at the bid throughout.	Persistent size at one strike with bid-side fills — the OI update, not the tape, will say which side opened.
SPX (index)	$8.2M into SPXW Oct 2 6875/6900 puts (9% below spot; one line 1,754x its OI); paired 7635–7645 calls-and-puts prints again bracketed spot; a single $26.7M burst in Jan 2027 8000 calls.	Tails bought on both wings while the straddle-shaped pairs keep marking the range — positioning for a wider distribution, not a direction.
SQQQ	$2.46M at the Sept 18 $37 call, ask-side fills, volume just past OI.	Calls on the inverse-QQQ fund are a bearish-QQQ expression; printed the session QQQ broke its floor.
MU	Three flagged lines: Sept 2 $940 put sweep ($1.04M, expires Wednesday), Sept 9 $960 calls ($1.57M, ask-side, 17x OI), Sept 18 $975 puts ($1.35M, 29x OI). MU closed $933.44.	Short-dated two-way size around spot a month before earnings — a volatility argument, not a directional one.
SNOW	$1.07M at the Sept 11 $327.50 call, volume 17x OI, fills at the bid; SNOW reports Wednesday postmarket.	Pre-earnings positioning at a near-zero-OI line — Wednesday’s print scores it fast.
AGX	Two all-opening floor prints, $6.1M combined, at the Sept 18 $410 and $480 calls — 44x and 55x their standing OI; reports Wednesday postmarket.	Floor-routed, fully opening, day-before-earnings size in a $6B name — the least ambiguous prints on today’s tape.
ANET	$3.70M sweep at the Jan 2028 $190 put, volume 12x OI, fills at the bid.	LEAP put size printed at the money; bid-side fills leave the opening side unproven until the OI check.
TSLA	$2.47M across two bursts at the Jan 2027 $380 call; volume ran just past the 4,405 OI.	Upside interest 7% above spot in a name that closed flat on a down tape.
ORCL	$1.50M at the Dec $145 put, fills at the bid; ORCL reports Monday Sept 8.	Put size a week ahead of the print, at a strike just above spot — the OI update says whether it stands.

The set-up

Two sessions, one story: an orderly tape quietly re-pricing its risk. Monday was month-end housekeeping — trillion-dollar-scale tracker crosses, a flat QQQ, a bounce in NVDA. Tuesday was the tell — the floor broke, VIX left the 14s, the deep-strike put tape opened from near-zero bases, and the classifier moved off Bull for the first time in this run of editions. Against that, the confirmed positioning is not one-sided: the SPX January call wing keeps building, TSLA upside printed, and the two-day index damage is still under one percent. Wednesday’s four postmarket reports — AVGO, HPE, SNOW, AGX, every one carrying flagged options positioning — are the nearest thing to a scheduled verdict on which side of Tuesday’s re-pricing gets paid.

Notable data points

1. Five dark-pool prints crossed within one second at 5:05:04 PM Tuesday — NVDA, GOOG, GOOGL, MSFT, SPY — each engineered to within $400 of $500M.
2. The SPY Nov 30 $684 puts traded 18,800 contracts Tuesday against 15 contracts of standing open interest.
3. HPE’s Jan 2027 $46 puts grew from 1,813 to 5,510 contracts of OI in two sessions — the report lands Wednesday.
4. NVDA’s Sept 4 $225 calls shed 21,814 contracts of OI over two sessions after Friday’s 94,121-contract churn.
5. Market-wide put/call rose to 0.87 Tuesday from 0.74 Friday; SPY’s own ratio printed 1.18, QQQ’s 1.21.
6. NVDA closed the two-day stretch at $217.44 — eleven cents below Friday’s close — after a +1.5%/−1.5% round trip on $1.93B of Tuesday dark-pool prints.
7. AMZN fell 4.3% over the two sessions to $254.92, leaving Friday’s flagged $267.50 puts deep in the money.
8. Tuesday’s $100M+ dark-pool tape ran $20.6B across 89 prints, with single names ($11.1B) out-weighing index trackers ($9.6B) — the reverse of Friday’s split.

Method note

Flow and dark-pool data sourced from Unusual Whales. MPI score and regime classifier are our internal composite; daily synthesis is AI-assisted from those inputs.

Volume-over-OI activity is unconfirmed as new positioning until the next morning’s open-interest update; confirmations are published in the following session’s post.

Board baselines are trailing-session averages computed from our own archived pulls; derived indicators are computed by AZTMM from licensed market data. The trailing baseline was offline for this edition, so boards publish without average comparisons rather than with estimated ones.

Combined-edition provenance: the desk publisher was offline Monday 31 August and Tuesday 1 September; the automated fallback posted condensed snapshots both evenings, and this post upgrades Tuesday’s in place under the desk’s standing repair rule. The open-interest check above therefore covers two sessions cumulatively and is labeled as such. Monday’s flagged-options screen was not retrievable at this run’s depth, so Monday is covered from price data, per-ticker options aggregates, and the off-exchange tape.

The vendor’s VIX close for Monday 31 August printed at 14.00 — below that session’s 14.86 low, failing the close-versus-range sanity check — so Monday is reported as a range (14.86–15.48). Tuesday’s close of 16.00 passes the same check and is printed. A second vendor divergence is noted for the record: our pipeline’s independent Tuesday VIX capture read 14.92; the strip carries the value consistent with the same source as the SPY/QQQ closes.
