Bitcoin ETFs Take Nearly $1B in a Day as Average Holder Returns to Profit

U.S. spot Bitcoin exchange-traded funds took in $998.95 million on Monday, reversing a weak week in which the same funds posted their smallest weekly net inflow on record. SoSoValue reported the one-day haul, and Bloomberg Intelligence described it as the biggest single-day intake since October 2025.

BlackRock's IBIT led Monday's flows with $381.37 million. Ark & 21Shares' ARKB drew $289.12 million and Fidelity's FBTC added $238.84 million. Other managers also recorded inflows: Morgan Stanley's MSBT took $61.67 million and Bitwise's BITB $21.56 million, while Grayscale's two funds logged small single-digit millions. VanEck's HODL and Valkyrie's BRRR reported no flows for the day.

The price move accompanying those flows pushed Bitcoin above an estimated ETF cost basis of $81,722 per coin, a threshold Bloomberg analysts said puts the typical U.S. spot ETF holder back in profit for the first time since January. At the time of reporting, Bitcoin was trading near $85,900, roughly 5% above that estimated cost basis. Market participants noted that holders who had been underwater frequently sell once they break even, so this change in average profitability could affect future supply and demand dynamics.

Trading volume within the funds was about $4.5 billion, a figure described by Bloomberg analysts as not especially high given the size of Bitcoin's price move and slightly below the $4.6 billion traded on the prior Friday. Cumulative net inflows since the ETFs' launch now total $56.16 billion, and the funds hold $110.14 billion in assets — equivalent to 6.30% of Bitcoin's market capitalization. Analysts cautioned that reported flows for a single session can reflect trades executed in the previous session, so some of Monday's inflows may have captured earlier buying.

Market commentary tied the recovery to renewed institutional interest and regulatory developments, with one industry participant noting the resilience of recent price action despite macro and legislative headwinds. Observers said the coming days' flows and trading should help clarify whether institutions are adding fresh exposure or merely riding an existing rally.
