BlackRock’s Bitcoin ETF posts $528M outflow; BTC under $75K

BlackRock’s iShares Bitcoin Trust posted a $527.8 million net outflow on Wednesday as Bitcoin slipped below $75,000, part of $733.4 million pulled from U.S. spot Bitcoin ETFs that day. The withdrawals extended an eight-day streak of net redemptions totaling about $2.6 billion.

Farside Investors data show the IBIT outflow was the second-largest daily loss since the fund’s launch, just under the $528.3 million record on Jan. 30, 2026. The largest single-day outflow on record occurred Nov. 13, 2025, at about $866.7 million.

SoSoValue data indicate U.S. spot Bitcoin ETFs have flipped to net outflows for 2026, with roughly $596 million withdrawn year to date. May accounted for about $2.1 billion in redemptions, the largest monthly outflows recorded this year.

CryptoQuant analysts flagged $70,000 as a potential next price support level if selling pressure continues, based on exchange flows and on-chain metrics.

10x Research noted that Strategy, the largest publicly traded holder of Bitcoin, could face funding pressure in coming months if it needs to meet dividend obligations. Strategy bought back $1.5 billion of debt at a discount and reduced outstanding notes to about $6.7 billion. In mid-May, Strategy co-founder Michael Saylor wrote that sticking too rigidly to a “never sell” approach might not be sustainable.

Wednesday’s outflows left funds and traders watching price action and on-chain signals for signs of stabilization or deeper declines. Fund flows have been volatile in 2026, with earlier inflows reversing into the current stretch of withdrawals.
