The week of Monday, May 25 through Sunday, May 31, 2026.
The headline
Bitcoin booked its third consecutive risk-off week and gave back another 7.17%, sliding from an opening print of $77,254 on Monday to $71,714 by Sunday close, with the period’s low arriving on its final tick rather than mid-window. Sentiment tracked the price, with the Fear and Greed Index sliding from 34 to 29 and bottoming at 22 on May 28 — squarely inside Extreme Fear. The driver was structural: US spot Bitcoin ETFs spent the week in sustained net redemptions, with the editorial archive framing the run as a ten-day, roughly three-billion-dollar streak — the longest on record — and a single $1.29 billion dark-pool block sale of BlackRock’s IBIT on Tuesday acting as the defining event. The S&P 500 rose 1.43% and the VIX eased 5.05% over the same window, leaving Bitcoin selling off into a calm risk tape rather than a broad panic.
Price and macro backdrop
Bitcoin opened the window at $77,254 on Monday, May 25, peaked at $77,978 on Tuesday, May 26, and ground steadily lower over the following six sessions, closing at $71,714. The weekly average sat at $74,378, and the $6,264 distance between high and low captures the shape of the move: a single early test above $77,900, no follow-through, a back-half slide that produced no relief bid. The floor arrived with the final tick, not before.
The pressure was Bitcoin-specific against a calm equity tape. The S&P 500 added 1.43% to close at 7,580.06, while the VIX eased 5.05% from 16.64 to 15.80 — readings that describe orderly conditions, not stress. Gold added 0.30% to $4,536.90 after a $4,398.80 low on May 28 in response to the day’s geopolitical shock. MicroStrategy slipped 0.50% to $159.09 on a weekly basis, though the path was less placid than the endpoints suggest: the stock printed a low of $146.40 on Thursday, May 28, in tandem with Bitcoin’s six-week low, before recovering most of the drop. The dominant macro thread was JPMorgan’s framing of parallel softness in Bitcoin and gold ETF flows as a “cooling debasement trade,” tied to easing US-Iran tensions reducing macro hedging demand after the prior week’s escalation peak.
ETF flows
Across the four reported sessions in the window — Tuesday, May 26 through Friday, May 29 — US spot Bitcoin ETFs shed roughly $1.42 billion in net redemptions, extending what the editorial archive characterized as a ten-day, roughly three-billion-dollar streak running back into the prior week and standing as the longest on record. The damage was concentrated. BlackRock’s IBIT lost $966.3 million net across the four days, with no inflow session at any point and a single-day exit of $527.8 million on Wednesday, May 27 — the print that flipped year-to-date IBIT flows negative and that the archive attributed in part to a $1.29 billion dark-pool block sale executed Tuesday, the largest such trade observed on the fund. GBTC continued its bleed at $175.2 million net and FBTC shed $169.1 million, both paced by Wednesday exits of $104.8 million and $60.3 million. Smaller cumulative outflows came from BITB at $46.3 million, BTC at $33.0 million, ARKB at $24.7 million, and MSBT at $1.0 million; BRRR, BTCO, BTCW, EZBC, and HODL closed flat. No fund posted a net-positive week. NYDIG attributed the largest single-day IBIT exit to a directional holder unwinding below market rather than a basis-trade reversal — a distinction worth carrying into next week, because directional unwinds tend to be discrete events while basis unwinds cascade.
On-chain and mempool
The network strengthened while spot softened. Hashrate rose 13.69% over the period, from 886.35 EH/s to 1,007.69 EH/s, with an early-week peak of 1,130.40 EH/s on Tuesday, May 26 — the opposite of the capitulation pattern a price-led hashrate decline would suggest. Spot drawdowns and miner pullbacks often arrive together. This week, they did not. The halving epoch reads 52.84% complete, 772 days in.
Mempool conditions were less straightforward. Pending transaction count fell 28.4% from 110,211 to 78,903 and mempool virtual size fell 32.5% from 43.6 to 29.4 million vbytes, with a Thursday morning low near 415,000 vbytes that briefly cleared the chain. Total mempool fees, however, rose 15.8% from 13.5 million to 15.7 million sats per ten-minute sample. The bag thinned out, but what remained was paying more per byte. Fewer-but-fattier is a regime, not noise.
Derivatives
The CFTC commitments-of-traders snapshot dated May 26 put Bitcoin futures open interest at 21,625 contracts, equivalent to 108,125 BTC and $7.95 billion in notional terms — a single weekly print, best read as a level rather than a move. Two structural developments landed alongside it: the CFTC approved regulated Bitcoin perpetual futures on the Kalshi exchange, opening the first domestically regulated US venue for the product, and CME Group announced 24/7 Bitcoin futures, which would end the weekend gap as a structural feature of institutional trading.
Order book regime
The order book at the window’s close told a different story from the price tape that preceded it. The midpoint sat at $71,847.51 with imbalance at +0.298 — a bid-heavy reading against a 24-hour baseline average of -0.070 — and the dominant wall was posted on the bid side, with prominence 9.72, sitting almost exactly at the touch. Bid-side depth in the 2% band measured 9.30 BTC against 5.03 BTC of ask depth, leaving the visible book skewed almost two-to-one toward buyers near the close. The spread held to a fraction of a basis point throughout. A market that has just printed its weekly low with a bid wall at the touch is not the microstructure of capitulation. It is the microstructure of a probe.
News and policy threads
The week’s editorial archive carried three interlocking threads. The first was the structural ETF exit, framed less as a flow story than as an institutional positioning event: the IBIT dark-pool block on Tuesday, the second-largest single-day IBIT outflow on record at $528 million on Wednesday, and the ten-day streak that pulled year-to-date US spot ETF flows negative for the first time in 2026. By Friday capital was rotating into AI semiconductors and precious metals, and CryptoQuant flagged stalled whale and large-holder accumulation as a buyer drought rather than a conviction call.
The second thread was geopolitical. Renewed US airstrikes near the Strait of Hormuz mid-week triggered roughly $935 million to $1 billion in leveraged liquidations across two days and pushed Bitcoin to a six-week low near $72,600 on Thursday — a move the archive read as a re-pricing of geopolitical risk rather than a Bitcoin-internal break. By the back half of the week the news flow had shifted to ceasefire progress.
The third thread was the on-chain counter-narrative to the flows story. The long-term holder address count reached an all-time high of 15.8 million by the end of the window, even as short-term holders moved over 107,000 BTC in a single session — a movement-volume figure the archive associated with capitulation. The mismatch describes a drawdown, not a top. Strategy paused its weekly accumulation in favor of retiring $1.5 billion in convertible debt at a discount while still holding 843,738 BTC; Strive added 1,109 BTC to reach 16,500. Elsewhere, Banca Sella became the first Italian bank licensed under MiCA to offer Bitcoin services, Kraken launched a Bitcoin Vault yield product routed through Aave and Morpho, and ARK Invest reaffirmed a 2030 base case of $750,000.
The week ahead
The macro calendar tightens immediately. The next CPI release falls nine days out, on June 10, and the next FOMC decision fifteen days out, on June 16 — both inside a single two-week window after a stretch in which scheduled US data was scarce. The setup hands the tape to a different question than last week’s: not whether flows can stabilize without a catalyst, but how the flow regime reacts when one arrives.
Three items frame the watch. Whether the ten-day spot ETF outflow streak breaks early or extends through the CPI print is the cleanest signal on whether the institutional unwind is event-driven or structural. Whether the order book’s bid-heavy close holds into Monday’s open, or fades back toward the bearish 24-hour baseline, will indicate whether late-week dip-buying interest has follow-through. And whether the record long-term holder count continues to climb against active short-term distribution will tell which side of the on-chain split is winning the slow contest. With sentiment at 29 and Bitcoin sitting on a fresh local low at the start of an event-heavy fortnight, the resolution comes from the catalysts, not from the chart.
