Bitcoin ETF loses $2.26B in 2 weeks: Is the institutional exit real?

What happened

• Bitcoin dropped as much as 2.5% to $73,294 in Singapore Thursday morning, its weakest level since April 14, per Bloomberg.
• Ethereum fell more than 4% to $1,970, its lowest in almost two months, underperforming Bitcoin as it typically does in macro-led selloffs.
• An unknown institutional investor sold 29 million IBIT shares worth $1.29 billion via a dark pool at 10:30 a.m. ET on May 26, one of the largest off-exchange Bitcoin ETF transactions ever recorded, confirmed by Bloomberg ETF analyst Eric Balchunas.
• The dark pool trade sent Bitcoin tumbling 1.45% within 10 minutes, from $77,870 to $76,721. The coin hit a 24-hour low of $75,600 roughly 12 hours later.
• US spot Bitcoin ETFs have bled a combined $2.26 billion since May 14, with outflows recorded on nearly every trading day since May 7, per Glassnode.
• BlackRock’s IBIT alone shed $192.4 million in net redemptions on Tuesday, on top of the $1.29B dark pool trade, per SoSoValue.
• XRP fell 3.03% to ₹123 in Indian markets. BNB dropped 1.91% to ₹61,339. Tether was the sole gainer, up 0.66% to ₹96.

Why is Bitcoin falling? The three drivers

• The $1.29B dark pool dump: An anonymous entity sold 29 million IBIT shares off-exchange on May 26, 22 times larger than the second-biggest IBIT sell order of that session. Bitcoin dropped 1.45% in 10 minutes. Dark pools exist so large institutions can unload massive positions without instantly cratering public markets. That they needed one this big tells you something.
• Macro headwinds — yields and dollar: Rising US Treasury yields have tightened global financial conditions. A firmer dollar is squeezing risk assets everywhere. Bitcoin’s weakness “looks mostly macro-driven, not crypto-specific,” said Sean McNulty, Asia-Pacific derivatives trading lead at FalconX.
• Iran-US geopolitical flare-up: US Central Command carried out fresh airstrikes on Iranian missile facilities and a naval mining vessel. Bitcoin reacted almost immediately to the headlines, an increasingly common pattern. BTC dropped roughly 1% from above $77,000 to just below $76,500 following those reports.

The ETF exodus — by the numbers

The number the market is really watching: 33

• Swissblock’s Bitcoin Risk Index climbed to 33 out of 100 on Tuesday, firmly in “high-risk territory.”
• The index measures the balance between selling pressure and buying demand. A score of 33 means sellers are structurally overwhelming buyers.
• “Every time the Risk Index signals that selling pressure is structurally overwhelming the market, what sits underneath is institutional distribution,” Swissblock said.
• The firm flagged that Bitcoin shifted from strong accumulation in March and April to a distribution phase in May — a full reversal of the trend that drove prices higher in Q1.
• Glassnode separately noted that Bitcoin ETFs have seen outflows on “nearly every trading day since May 7,” calling it “a persistent institutional sell signal now running for more than two weeks.”
• On-chain apparent demand, how much Bitcoin the market is actually absorbing relative to new supply, is back to its weakest level since December 2025.

Support levels every trader is watching

One angle most articles missed

The dark pool trade on May 26 is being read as bearish. But there is a counterargument worth noting. Bloomberg ETF analyst Eric Balchunas confirmed the trade and added, “Price unchanged today, so the market absorbed it well.” Nic Puckrin, co-founder of Coin Bureau, told Sherwood News that the fact there was liquidity and execution for a $1.29B trade on a 2-year-old ETF is evidence of market maturity, not fragility. Georgii Verbitskii, TYMIO derivatives trader, said the decline was not deeper because the market was able to absorb supply. The bearish case and the maturity case are both valid. The question is which dynamic is dominant in the next 72 hours.

What’s next—triggers to watch

• US PCE inflation data (due this week): if it comes in hot, Treasury yields spike further, and Bitcoin’s floor gets seriously tested.
• Bitcoin’s 50-day and 200-day moving averages are approaching a “golden cross”—a historically bullish technical signal, per FXPro’s Alex Kuptsikevich.
• Prediction markets now give a 64% probability that Ethereum falls below $1,750 in 2026, up from 57% at the start of May.
• Weekly ETF flow data (published Friday by Farside/SoSoValue) will be the clearest signal on whether institutional demand is returning or deteriorating further.
• If IBIT net outflows continue for a third consecutive week, 2026 net inflows turn negative, the first time that would happen since the product launched.
