Markers Wednesday: September's First ETF Session Was a $236.5m Outflow — and the First Session Has Called the Month's Sign Exactly 16 Times in 32

September's first ETF session was a $236.5 million net outflow on Farside's completed table, the largest since 31 July, and IBIT's $201.2 million was that fund's largest since 24 July. H2, the marker that says September finishes positive, opened underwater. Before drawing any conclusion from an opening session we did the thing this desk keeps saying it will do and pulled the whole record: in the 32 complete months since the spot ETFs launched, the sign of the first session has matched the sign of the month exactly 16 times. A coin. The rest of the board moved too — the difficulty projection gave back 0.62 points, the September basis fell more than a point to 4.29% annualised, and the crowd flipped from net short to net long on the first red day — and one marker, H1, now needs 3.43%.

The board

Ten rows, three new. Nothing settles today. The nearest settlement is D2/F1 on Saturday night's retarget, and the projection that decides both has now moved 1.79, +1.09 and −0.62 points on three consecutive days, so we are not pre-grading it.

H2 opened negative — and the first session has called the month 16 times out of 32

The temptation on a −$236.5 million opening session is to write the month's obituary; the opposite temptation, given that both prior Septembers were green, is to wave it away. Neither is an argument. So we took Farside's all-data table — 678 rows, 11 January 2024 to 1 September 2026 — grouped it by calendar month, dropped the incomplete current month, and compared the sign of each month's first session to the sign of its total.

Thirteen rows shown of thirty-two scored; the earlier nineteen run at 9 of 19. Sixteen of thirty-two. The first session has exactly no information about the month's sign, and the last thirteen months, at 7 of 13, are no better: May 2026 opened +$629.8 million and finished −$2.41 billion; July opened −$296.0 million and finished positive; January opened +$471.3 million and finished at −$1.6 billion. One caution on the table, in the same sentence as the number: Farside's row for 2 September 2024 is $0.0 because the US market was closed for Labor Day, so that month's "first session" is an empty row rather than a flat one. Scoring every month on its first non-zero session instead (3 September 2024 was −$287.8 million against a +$1,262.8 million month; 2 January 2025 was −$242.3 million against +$5,255.9 million) leaves the count at exactly 16 of 32 either way.

What the session does tell you is the size of the seller. $236.5 million is the largest single-day net outflow since 31 July (−$265.4 million), and IBIT's −$201.2 million is its largest redemption since 24 July (−$212.2 million). Of the twelve funds in the table, only BITB (+$8.4 million) took money. Cumulative net inflow since launch is now $54,679.8 million by our sum of the table, against Farside's printed $54,680; the two agree to rounding. One more clock-labelling note: a CoinDesk live blog headlined "Bitcoin ETFs resume buying" at 08:35 UTC Tuesday was correct — it described Monday's +$216.7 million — and readers who saw the headline after Tuesday's table completed were reading a true sentence about the wrong day.

H1 moved away: $80,318 is now 3.43% up

Strategy's 4,603-coin tranche was bought at an average of $80,318; H1 asks whether bitcoin closes above that figure on Bitstamp by 30 September. Tuesday's close was $77,397.43, −1.494% on the day, and the snapshot is $77,656.77, so the bar is +3.427% away, from +1.695% at the same time yesterday. Yesterday's tranche arithmetic updates mechanically: 4,603 coins at $77,656.77 are worth $357.45 million against a $369.70 million cost, −$12.25 million, −3.314%, roughly double Tuesday's −$6.0 million. The whole 845,050-coin position at $75,412 average is +$1.897 billion, +2.977%; the constant for readers stays $845.1 million per $1,000 of bitcoin.

The difficulty projection gave back 0.62 points

Mempool.space at the snapshot: +0.796% at 73.56% of the period elapsed, 533 blocks to the retarget at height 965,664, estimated Saturday 5 September, 22:23 UTC, from a tip of 965,131. That is −0.6192 points from yesterday's +1.4151%, after +1.0915 the day before and +1.79 the day before that; the average block time over the period is 595.7 seconds against a 600-second target. Current hashrate on the three-day window is 924.62 EH/s, effectively unchanged from yesterday's 924.36, so the retreat in the projection is the last day's blocks coming in slower rather than hashrate leaving. D2 (between −1.50% and 0.00%) fails on this reading; F1 (at or above zero) passes with a cushion that has gone from 1.42 points to 0.80 in a day. Fees are at 1 sat/vB across every tier, the thirteenth consecutive day at the floor since 21 August. The long-end guide is not the one for this; the difficulty guide in the Reading Room is.

Leverage: coins in, dollars out, and the September basis fell more than a point

Binance BTCUSDT perpetual open interest at the 2 September 00:00 UTC snapshot: 108,296.678 BTC and $8,382.48 million, from 107,978.168 BTC and $8,481.63 million a day earlier. Coins +0.295%, dollars −1.169%, implied mark −1.460% ($78,549.50 to $77,402.93). The identity closes: 1.00295 × 0.98540 = 0.98831, and 8,382.48 / 8,481.63 = 0.98831. Roughly 319 coins of new exposure were added into a red day, which is small, and not the deleveraging G1 needs — the perp book is 8.30% above the 100,000-coin bar with 28 sessions to run, and the live figure at 06:11 UTC was 108,813.63, higher again.

The term structure did something larger. COIN-M September quarterly at the snapshot: $77,903.1 against an index of $77,692.25, a premium of 0.2714% with 23.08 days to the 25 September delivery, 4.293% annualised — from 5.468% yesterday, a fall of 117bp in a day. December: $78,793.9, 1.418% over 114.08 days, 4.537%, from 5.083%. The curve is still inverted (September above December) but by 24bp instead of 38.5. Against the Treasury's 3-month bill at 3.92% and 4-month at 3.97% that is +37bp and +57bp of excess carry. Correction: yesterday's Markers printed the equivalent figures as +156bp and +151bp; the September number was right, the December one was not — 5.083% less the 3.96% four-month bill is +112bp, not +151bp. The error was caught this morning by a delegated arithmetic pass over today's draft, which flagged the carried-forward figure as inconsistent with yesterday's own basis print. Found by the check, not by the desk, again. G2 needs the September contract above 8.00% by expiry; it now needs +371bp with 23 days to run, and the direction of travel is the wrong one. That is why I3 is on the board: a bar in the other direction, 4.00%, 29bp away, where we do not know the answer.

Funding, by contrast, barely moved. The last 90 settlements on Binance BTCUSDT, starting 3 August 2026 08:00 UTC, average 0.006740% per eight hours, 7.380% annualised; 24 of the 90 are at the 0.01% cap and none is negative. Perp longs are paying 7.4% for exposure the September contract offers at 4.3% — the gap between the two legs widened from about 200bp to over 300bp overnight, which is what it looks like when the dated bid steps back and the perp crowd does not.

The crowd flipped net long on the first red day

Binance's global long/short account ratio for the 2 September 00:00 UTC bucket was 1.2862 (56.26% of accounts long), from 0.9948 the day before and 1.0812 the day before that; top-trader accounts went from 1.0563 to 1.3883. Two days ago we noted the crowd going net short into a green tape and refused to call it a signal on two observations. Today is the mirror image — net long into a red one — and the count is now three, which is still not a series. It is consistent with dip-buying by the retail cohort and with the small coin-count increase in open interest, and inconsistent with a market that has given up. We record it and move on.

Sentiment: fourteen days of Greed, and the run is shrinking

The Crypto Fear & Greed Index printed 63 this morning, −6 from Tuesday's 69, its fourteenth consecutive Greed reading in a run that began on 20 August 2026 (the 19 August reading was 46, Fear). The run's readings, in order: 62, 72, 71, 66, 73, 74, 65, 71, 73, 68, 69, 62, 69, 63. The 12-day view yesterday was 23rd of 98 runs since 1 February 2018 on the full 3,130-reading series; we have not re-pulled that series this morning and so, per the standing rule, do not rank a fourteen-day run against it. The eleven-day piece has the method.

What is on the tape for the rest of the week

Gold stays barred as a marker input for an eleventh day: the price series we can pull ourselves is a token proxy, and the one everyone quotes is a futures contract we cannot pull, and this desk does not settle bars on numbers it cannot reproduce.
