BlackRock’s IBIT Clocks Biggest BTC ETF Inflow in a Month

Investors piled $269.3 million into BlackRock’s iShares Bitcoin Trust on Thursday, in its best-performing day since early March, around the time the US-Iran war started to kick into high gear. 

The inflows helped to end two days of net outflows among the 12 US spot Bitcoin ETFs, which recorded a net inflow of $358.1 million.

Bitcoin ETF inflows are just one way to gauge retail and institutional demand for Bitcoin.

The Fidelity Wise Origin Bitcoin Fund (FBTC) brought in the second most inflows at $53.3 million, while the new Morgan Stanley Bitcoin Trust (MSBT) was the next biggest contributor, recording $14.9 million on its second day of trading, according to data from Farside Investors.

The Bitcoin ETFs issued by Bitwise and ARK 21Shares saw $11.7 million and $4.8 million worth of inflows, while Franklin Templeton and VanEck’s Bitcoin products tallied around $2 million.

BlackRock’s IBIT has now seen $1.5 billion worth of net inflows this year, withstanding a broader crypto market pullback, which has seen Bitcoin’s price fall from a 2026 high of $97,000 to $72,100 at the time of writing.

BlackRock’s digital assets head, Robert Mitchnick, said in March that investors of BlackRock’s IBIT have shown to be “disproportionately long-term buy and hold” investors — even when there’s been strong selling pressure elsewhere in the Bitcoin ecosystem.

Meanwhile, Morgan Stanley’s digital asset head, Amy Oldenburg, noted in an interview with Bloomberg on Thursday that MSBT was the institutional bank’s best-performing ETF launch ever.

“This is just the first of a long roadmap of new products on the asset management side,” Oldenburg said. 

Morgan Stanley has also filed to list a staked Ether (ETH) ETF and Solana (SOL) ETF.

With the latest day of inflows, US spot Bitcoin ETFs are now close to tipping back to a year-to-date net inflow. 

The Bitcoin ETFs finished 2025 at $56.59 billion in net inflows and are currently at $56.51 billion, meaning that they’re just $80 million away from clawing back to their inflow figures at the start of the year.
