- [confirms] Bitcoin ETF Buying Streak Ends With $225 Million in Outflows, Led Almost Entirely by BlackRock (2026-07-25): Bitcoin ETFs saw $225 million of July 23 outflows with BlackRock's iShares trust accounting for ~90 percent, even as Morgan Stanley's newer fund kept taking in cash (edition report). A single issuer driving nearly all of a day's redemptions demonstrates how concentrated ETF flows set the marginal move.
