Everyone will see the 2.4% dropthe asymmetry is that the whales' own short shrank into it.
Case #20260916 · 16.09.2026 07:30 UTC · BTC$75,759 / ETH$2,397 · analysis: Opus 5 by Anthropic
📅YESTERDAY
Tuesday's 15.09 expiry settled at 08:00 UTC. BTC came in at $77,025 — 0.6% from max pain, a match inside tolerance, and the market-maker break-even corridor held. ETH settled at $2,477 against max pain of $2,540 — 2.6% apart, no match, but the corridor held there too. The max pain here is the one the code computes on the combined book at settlement.
The corridor has held in both assets for a seventh day running. The code closed no case over the day; the registry took in six new ones.
⚡THE GIST
• The market sagged: BTC lost 2.4% over the day and went down to $74,920, ether lost 4% — the widest day of the week in both assets.
• The funds turned inside one day: on Tuesday $450M left the spot BTC funds against $160M of inflow on Monday; the sellers were Fidelity, BlackRock and Grayscale.
• Ether whales took part of the short off into the fall: the short side among the top Hyperliquid whales shed $86M, the long side $50M — both sides walked out.
• The price of downside protection jumped: BTCskew+2.3 against +0.8 yesterday — the strongest tilt toward puts of the week, and in ether it turned toward puts as well.
• Verdict — continuation ⟳: the whales' tilt toward short is still standing, but it is shrinking, and three of the five camps of witnesses sided with it for the first time this week.
• 📊 Our Polygon — Pendulum: standing position, $0 on the day, +$9,642 in total since 11.05.
• 📊 Our Polygon — signals: best — Dust Strategy V2 +$88,469 at a 5% win rate · worst — Wheel Trail V8 −$8,787. Table at the bottom.
🐋WHALES: WHAT CHANGED — three arenas
Arena one — Hyperliquid futures. The fall split the two assets once more. In ETH both sides shrank: the short by $86M, the long by $50M — the whales cut in both directions, and the short-to-long tilt stayed at 2.1 times, almost as it was yesterday (how we track whale positions). In BTC the opposite: both sides grew — the long by a quarter, the short by a twelfth — so the ratio compressed to 2.6 times from 3.0. Inside the day the BTC tilt reached 3.9 times, when spot was at its low, and came back to 2.6 after someone picked up $57M of longs in two hours. Overleveraged whales: 60, as yesterday, two thirds of them long, but together they hold $720M against $877M — a fifth less. No forced closures among the top whales.
Arena two — Deribit options. Two separate whale positions, and they face different ways. The first — quiet accumulation in small lots outside the blocks. In BTC all three of the week's biggest footprints are calls, above the market. In ETH the biggest footprint is a call as well, on this week's expiries, and the second biggest is a put, below the market. The second — block trades (what a block is). Over two days the snapshot recognised 78 structures in BTC and 31 in ETH — twice as many as yesterday. The two most visible are identical cases to the end of October: a whale sold calls and bought puts on the same strike below the market, which assembles a synthetic short, and was paid a large premium for it. Next to them — an aggressive bearish structure on 600BTC and a sold call ceiling.
Arena three — money at the exchange border. Coins leave the exchange, cash comes in. In 24 hours eight tranches of ETH and one of BTC left Hyperliquid for market-maker addresses, about $7.3M together, while cash went out in three tranches to another exchange's deposit address. The "bridge" channel is USDC cash: over seven days $51.7M came in and $13.0M went out. The "Unit" channel is coins: over the week BTC gave back three times more than it took in, and in ETH the outflow beat the inflow as well. Where the withdrawals go: 25% of everything withdrawn went to exchange addresses, against 28% yesterday. Border snapshot 16.09, 07:30 UTC.
This is positioning, not a direction forecast.
🧭CROSS-CHECK — five camps of witnesses
Witnesses are independent data sources that back up or contradict the whales' positions.
What the funds are doing. Spot ETFs are the only camp that measures purchases of the coin itself, not a leveraged position. On Tuesday 15.09 $450M left the spot BTC funds — in one day the market took back more than the whole of Monday's inflow; the sellers were Fidelity's FBTC, BlackRock's IBIT and Grayscale's GBTC. The week to 15.09 comes out at −$706M because of it, against +$724M the week before. Out of the ETH funds went $141M on Tuesday, yet the week is still positive: +$201M against +$106M the week before. This confirms the whales: the institutions walked out of both coins on the very day price fell — that is selling of the coin itself, not of a leveraged position.
What the options market says. This camp measures one thing: what insurance costs on Deribit. BTCskew+2.3 against +0.8 yesterday: puts have become markedly dearer than calls — the market is paying more for downside protection than at any point this week (what skew is). In ether skew turned to +0.9 from negative. Our fear-and-greed index stands at 83 out of 100 against 86 yesterday — greed has been backing off for a third day. BTC two-day vol sits in the 59th percentile of its own hourly history since February against the 65th yesterday — two-day insurance got slightly cheaper even on the fall (what implied vol is). This confirms the whales: the tilt toward puts and the whales' short say the same thing — downside risk costs more right now.
What the futures say. This camp measures who pays whom to hold a position. ETH funding on Hyperliquid has turned over: −0.006% in eight-hour terms against +0.003% yesterday — shorts now pay longs (what funding is). In BTC it is +0.010%, as yesterday. This contradicts the ether whales: the ether short became a position you pay for exactly when the whales started cutting it.
What the crowd is doing. This camp measures how retail accounts stand against the whales. On Bybit perps 62% of BTC accounts stand long against 57% yesterday, and ETH is at 70% against 67% yesterday: retail bought the fall in both assets. The gap between the crowd and the whales is at a monthly maximum in both assets — 33.9 points in BTC and 37.0 in ETH, the first time this week that both sit there at once. This confirms the whales: retail built longs into the fall, the whales stand on the other side, and the distance between them is the widest in a month.
Any signs of stress. This camp measures whether anyone has already been forced out of the market. Among the top Hyperliquid whales, not one forced closure over the day. On OKX swaps $1.3M was liquidated, almost all of it longs — 11% of the week's volume, an even background with no acceleration. This camp is silent: a 2.4% fall passed without a cascade, and the position size of the overleveraged whales shrank by a fifth over the day on its own.
Again: this is positioning, not a direction forecast.
🌡ALTSEASON — the classic and our barometer
The classic altseason index stands at 29.7 out of 100 — bitcoin-season territory, the lowest value of the week.
Our barometer watches money, not prices: open interest, funding and retail come from Bybit perps, the whales from the Hyperliquid registry. Alts' share of open interest is 40.5% — $4.23B of $10.43B, down half a point over the day.
Alt contracts with funding hotter than bitcoin's make up 38% of open interest — the lower half of the week's range.
Retail in the top-10 coins stands 70.6% long; the hottest are XRP and DOGE at 79% and 78%.
Whales in alts are structurally short: 33.8% long across $1.04B of positions, the biggest of them HYPE. That gap itself is permanent; the signal is in its CHANGE — and over the day it didn't move.
Full barometer: indiciadesk.com/en/altseason
⚖️VERDICT OF THE DAY
continuation ⟳ — the whales' tilt toward short has stood for a fourth day, but the tilt itself is melting: in ether the whales took part of the short off into the fall, in bitcoin they added to both sides. For the first time this week the witnesses came together: three of the five camps — the funds, the options skew and the crowd — back the whales, ether funding contradicts them, and stress is silent.
What this does NOT mean. It isn't a claim that the fall continues. The biggest fund selling and the dearest downside protection of the week describe yesterday, not tomorrow; when every witness faces the same way, the market has already paid for that view.
🔒In today's full RADAR:
— a whale assembled two identical synthetic positions against bitcoin for the end of October and was paid over a million in premium — strikes, legs and payoff profiles;
— the market's biggest ether short cut its unrealised loss by ten million over the day without closing a thing — and who it is.

🔬Who exactly
Both of the biggest shorts are Abraxas Capital Mgmt (Heka Funds). Over the day the house cut its ETH short by $19M across two addresses and grew its BTC short by $15M — on the fall the house is moving weight from ether to bitcoin. The house's unrealised loss fell from $53.6M to $32.0M over the day. Margin across the two accounts is $179.9M against $188.3M yesterday.
Fasanara Capital turned over the day: the ETH short was cut to $35.3M, and a BTC SHORT of $24.5M was opened at 30× leverage with liquidation at $174,228 — a week ago this address stood long in bitcoin. Account $36.8M.
The 10× BTC short is self-labelled VBVIT; nicknames aren't treated as identification.
The 40× short sitting 2% from liquidation, the new 40× BTC long and the new 25× ETH long are addresses without a public label.
Money by address. Over the day the coin channel handed over eight ETH tranches of $0.7–0.9M each and one BTC tranche of $2.8M — all to Wintermute addresses; cash left in three tranches of $0.4–0.6M to an OKX deposit address, and ETH and SOL came back in from Binance. This is the second day running that coins go to the market maker.
🔒THE WEEK'S DYNAMICS 🔬
Perps.BTC: net $280M short (long $177M against short $457M), a $31M shift toward long over 7 days, $7M toward short over the day. ETH: net $310M short (long $280M against $589M), $5M toward short over 7 days, $13M toward long over the day — over the week neither asset really moved, the whole move happened inside the day.
Gamma flip.BTC$71,766 — up 1,593 in a single day, more than over the whole week (+1,336): the weekly window counts from a different base, so the daily jump is the number that matters here. Spot now sits only 5% above it; the call wall and the put wall each came down 1,000 over the week (what the flip is). ETH$2,392 — up 106 over the week, and spot stands right on it.
The price of fear. On the weekly window the premium is negative: IV38.5 against realised HV42.2 — minus 3.7, compressed by 3.8 over 7 days. Over the week the market travelled further than the options market had priced in, and the fall did not close that gap.
Changing of the guard. Over the week the whales assembled 201 confirmed structures: 57 bullish, 54 bearish, 21 on volatility, 69 on range — against 180 yesterday. Bearish added 13 over the day, bullish 4.
🔒CROSS-CHECK IN DETAIL 💠
BTC levels. Everything below comes from Deribit options open interest. The market-maker break-even corridor is $75,500–$78,000 against $77,000–$79,000 yesterday — it came down after spot, and spot sits near its bottom; by our study across 384 expiries price stays inside such a corridor in roughly 82% of cases (what the corridor is). Max pain $77,000 — 1.6% above spot (what max pain is).
The week's landmark — Friday 18.09.BTC: 20,977 contracts against 18,254 yesterday, max pain$78,000, put wall $72,000 on 2,504 contracts, call wall $79,000 on 2,130 — the ceiling came down from $82,000 over the day (what the walls are).
Ether this week. Today's 16.09 expiry carries 89,242 contracts — max pain$2,460, call wall $2,600 on 14,581. Thursday's 17.09 carries 64,581 contracts and holds the same $2,600 call wall on 40,823 contracts: 35,000 of them were bought in blocks the night before last, and after the day's fall those calls have moved 8% away from price.
ETH levels. The corridor is $2,380–$2,560 against $2,480–$2,580, max pain$2,460. Spot stands right at the bottom of the corridor.
The quarterly, Friday 25.09.BTC: max pain$72,000, put and call densest at $70,000 (9,372 and 10,943). ETH: max pain$2,200, put $2,100 on 36,938, call $3,000 on 42,691.
Fuel. Above BTC$50.9M of short positions in the $77,400–79,677 band against $31.0M of longs below the market in the $72,088–74,365 band — for the first time this week there is more than half again as much fuel above the market as below it. In ETH the reverse: $48.5M of long fuel below the market in the $2,283–2,355 band against $10.5M of short fuel above it. This is about the RANGE of a move for the same push, not about a higher probability of that move (what the fuel map is).
Gamma vacuum. In BTC it's dense above spot; empty below, at $71,000–$72,000. In ETH dense above spot; empty below, at $2,250–$2,300.
Stress test ±2%. For BTC and ETH, a 2% move from spot either way leaves the dealers in positive gamma — the move gets damped.
OI flow.BTC put/call across all expiries: month 0.56 · week 0.54 · now 0.55 — stable; ETH0.52 · 0.54 · 0.49 — ether's open interest has become the most call-heavy in a month (what put/call is).
Two options venues. On the same expiries up to 30 days BTC put/call is 0.54 on Deribit against 0.90 on Bybit — after three days of growth Bybit's open interest became less put-heavy over the day, from 1.12 yesterday; ETH0.53 against 0.79. We don't know who owns the Bybit positions, so this is neither "whales" nor "retail" — just a second venue with a different lean.
IV by tenor.BTC 2d P42/C42 · 9d P39/C37 · 16d P38/C36, percentiles since February 59th, 38th and 30th against 65th, 41st and 37th yesterday. ETH 2d P56/C56 · 9d P55/C52 · 16d P53/C51, percentiles 57th, 46th and 37th. BTCDVOL38.4 against 30-day realised 34.1 — a premium of +4.3; ETHDVOL 53.9, premium +3.3 (what the premium is).
💎SCENARIOS IN DETAIL 💠
The code's verdicts for yesterday. The code closed five scenarios. "Burn-up through the short fuel" from 13.09 confirmed — the high of $79,170 went through the $78,750 trigger. "The corridor holds" from 13.09 — partially, 90% of the time inside the band; from 14.09 — partially, 67%. "Burn-up through the short fuel" from 14.09 and from 15.09 were cancelled on their levels: the low of $75,582 went through both. The corridor and the slide from 15.09 run to tomorrow. The week since 09.09: 21 scenarios — 5 confirmed, 3 partially, 2 not, 9 cancelled on their levels, 2 still running. Whole history: corridor 8 of 22 plus 6 partial, burn-up 7 of 27, slide into the long fuel 4 of 15 — the directional types run worse than a coin toss, the corridor type under half.
The corridor holds — 40%. ⏱ 2 days, to Friday 18.09. BTC stays between the fuel bands, $74,400–$77,400. Cancellation level: a touch of $72,100 — the bottom of the long-fuel band.
Burn-up through the short fuel — 30%. ⏱ 2 days, to Friday 18.09. Trigger: a touch of $77,400 — the bottom of the band of short positions, which over the day grew bigger than the long band. Cancellation level: a touch of $74,350.
Slide into the long fuel — 30%. ⏱ 2 days, to Friday 18.09. Trigger: a touch of $74,350 — the top of the band of long positions. Cancellation level: a touch of $77,400.
This is how we weigh the odds — not a promise; the code will compute the verdict from spot history.
🔭WHAT TO WATCH
• Thursday 17.09, 08:00 UTC: settlement of the ether expiry holding 40,823 calls on a single strike — after the fall they sit 8% from price, and that whole wall leaves the market in a day (💠).
• The 40× BTC short with liquidation 2% above spot: a $1.6M account against a $49.2M position — any two-percent bounce closes it by force (🔬).
• The funds: after $450M of outflow on Tuesday, Wednesday shows whether that was a one-off or the start of a weekly run (🔬).

📅PUBLIC LEDGER
(computed by code at the settlement price)
The market-maker corridor. Across 384 expiries since February the market-maker break-even corridor held the settlement price 315 times — 82%. Tuesday's 15.09 expiry held in both assets — a seventh day running. Decision: we lean on the corridor, knowing that roughly one expiry in five it doesn't hold.
Max pain. An exact match with the settlement in 36% of those same 384 expiries. Yesterday BTC came within 0.6%, while ETH was 2.6% away — the widest gap of the week. Decision: we don't chase max pain — it is a landmark, not a magnet, and yesterday's ether showed exactly that.
The walls. The call wall held the settlement in 50% of expiries, the put wall in 42%: roughly a coin toss. Today's BTC expiry carries only 5,419 contracts while the ether one carries 89,242; we treat only the second as a level. Decision: a wall without an expiry and a contract count isn't published.
Whale structures by type (our Deribit registry, 721 closed cases). Risk reversal — the type of the day's two biggest new cases: 68 closed, 56% matched by strikes, yet −$1.84M in total for the whales. Bear call spread — two more new ones: 60 closed, only 20% matched, −$891k in total. All closed cases together: −$5.9M. Decision: win rate isn't money, and we don't copy whale structures — today's synthetic short on 400BTC promises nothing by itself, we track where it stands.
Polygon. Pendulum +$9,642 since 11.05 with $0 on the day. The Dust Strategy: 75 trades across both versions and +$122k together, a fourth day without new trades. Volatility Convergence: the day's only closed trade, in the red. Decision: we publish both tallies daily with the same denominator; we keep the Dust Strategy for the money it makes despite its win rate, and the Wheel Trail is the first thing we look at in every review.
📏Scale calibrator
• What protection costs. Our fear-and-greed index — 83 out of 100. We compute it from the price of volatility and the option skew on Deribit, not from news, which is why it diverges from the well-known index.
• Cheap or expensive for this market itself.BTC two-day vol — 59th percentile of the hourly history since February, nine-day — 38th, sixteen-day — 30th: further out from price, insurance is still cheaper than in most hours.
• Which way protection tilts.BTCskew+2.3 — puts markedly dearer than calls, and over the day that tilt grew almost threefold; ETHskew+0.9 after yesterday's negative. Terms: indiciadesk.com/en/glossary/
