Investors piled $269.3 million into BlackRock’s iShares Bitcoin Trust on Thursday, marking its strongest single day since early March — around the time US-Iran tensions began escalating sharply.
The surge helped end two consecutive days of net outflows across the 12 US spot Bitcoin ETFs, which together recorded a net inflow of $358.1 million.
Other ETFs join the rally
Fidelity’s FBTC brought in the second-largest haul at $53.3 million, while the newly launched Morgan Stanley Bitcoin Trust (MSBT) added $14.9 million on just its second day of trading, according to Farside Investors data.
Bitwise and ARK 21Shares saw $11.7 million and $4.8 million in inflows respectively, while Franklin Templeton and VanEck each tallied around $2 million.
Morgan Stanley’s record launch
Morgan Stanley’s digital asset head, Amy Oldenburg, told Bloomberg on Thursday that MSBT was the bank’s best-performing ETF launch ever.
Oldenburg said:
“This is just the first of a long roadmap of new products on the asset management side.”
Year-to-date picture
BlackRock’s IBIT has now accumulated $1.5 billion in net inflows year-to-date, even as bitcoin has pulled back from a 2026 high of $97,000 to around $72,100.
BlackRock’s digital assets head Robert Mitchnick noted in March that IBIT investors have proven to be “disproportionately long-term buy and hold” even during periods of heavy selling pressure.
US spot Bitcoin ETF flows finished 2025 at $56.59 billion in net inflows and currently sit at $56.51 billion, leaving them just $80 million short of clawing back to their year-start figures.
