BlackRock Bitcoin ETF draws $269.3M inflow — best day since March

U.S. asset manager BlackRock's iShares Bitcoin Trust (IBIT) drew $269.3 million in net inflows on Thursday, marking its strongest single-day intake since early March. The inflow helped reverse a short run of outflows across the U.S. spot Bitcoin ETF complex.

Data compiled by market tracker Farside Investors show that U.S. spot Bitcoin ETFs recorded $358.1 million in net inflows on the same day. Fidelity Investments’ Wise Origin Bitcoin Fund (FBTC) accounted for $53.3 million, while Morgan Stanley’s recently launched Morgan Stanley Bitcoin Trust (MSBT) added $14.9 million on its second day of trading; the two firms therefore contributed $68.2 million combined. The distribution highlights IBIT’s continued dominance alongside meaningful demand for other major issuers.

The ETF flows coincided with Bitcoin trading near the low- to mid-$70k range, and the fresh capital provided short-term buying pressure. Institutional allocations via spot ETFs represent direct demand against Bitcoin’s supply, which can underpin price stability when sustained. Nevertheless, market participants remain cautious given ongoing macro uncertainty and episodic volatility.

The episode fits into a larger pattern in which regulated ETF channels have become a primary conduit for institutional crypto exposure since their approval. IBIT has accumulated substantial year-to-date net inflows, underscoring investor preference for regulated products. Broader macro factors—Federal Reserve guidance, inflation data and geopolitical developments—will continue to influence whether inflows translate into a durable price trend.

Market commentators say that while large single-day inflows are constructive for sentiment, sustainable upside typically requires persistent net inflows and broader participation across issuers. Morgan Stanley executives have highlighted stronger-than-expected early demand for their ETF, suggesting that product launches and fee competition may reshape allocation dynamics among advisors and institutions in the coming months. Investors will be watching subsequent daily flow reports to assess whether this represents a rebound or a temporary reversion.
