IBIT bleeds $528M in a single day — second-largest outflow…

BlackRock's iShares Bitcoin Trust shed $527.84 million on Wednesday, the second-largest single-day net outflow since the fund launched in January 2024 — missing the all-time record of $528.3 million by less than $500,000. IBIT holds roughly $59 billion in assets and represents close to 4% of Bitcoin's total supply, making the scale of the redemption a meaningful signal for institutional sentiment.

The broader spot Bitcoin ETF complex lost $733.43 million the same day, with Fidelity's FBTC shedding $60.3 million and Grayscale's GBTC losing $104.76 million alongside IBIT. More than $2 billion has now been pulled from the 11 U.S.-listed spot Bitcoin ETFs over the past two weeks, as Bitcoin broke below $73,000 following U.S. airstrikes on an Iranian military site near the Strait of Hormuz.
