BlackRock buys 1,404.5 BTC worth $109.35M as ETF inflows return

BlackRock acquired 1,404.5 Bitcoin valued at $109.35 million through its spot exchange-traded fund on Sept. 2, extending a run of institutional buying that has yet to be confirmed by official holdings disclosures.

The purchase, reported by crypto media with transaction details only partially verified, follows the strongest month for US-listed Bitcoin ETFs in more than a year. Bloomberg's Isabelle Lee and Philip Lagerkranser put August inflows at roughly $3.5 billion, the largest monthly total since at least mid-2025, even as Bitcoin struggled to hold near $80,000.

August was the best month of the year for crypto ETFs, with about $3.3 billion of the total directed to Bitcoin products, according to data compiled by Bloomberg and shared by analyst Alex (@obchakevich_). Year-to-date flows remain negative at about $1.07 billion, and the August intake still fell short of the $4.51 billion that left Bitcoin ETFs in June alone.

BlackRock's iShares Bitcoin Trust has been the largest single vehicle for that accumulation. The world's biggest asset manager has steadily added to its holdings through the fund, which gives mainstream investors regulated exposure to Bitcoin without direct custody. The latest $109.35 million purchase is read more as a confidence signal than an immediate price driver, given the token's difficulty holding above $80,000.

The open question is whether the buying persists. Sustained inflows through IBIT and rival products would mark the return of the Wall Street investors who helped push Bitcoin into its institutional era, while a reversal would leave the recent rally exposed. Bitcoin was trading around $80,000 as of the Sept. 2 session, a level Bloomberg described as a test for the token's latest advance.

The accumulation is not confined to Bitcoin. BlackRock's spot Ethereum fund, ETHA, led US-listed Ether ETFs to a 12th straight day of net inflows on Sept. 1, adding $11.2 million as the group took in $10.95 million, according to SoSoValue data. The parallel flows suggest the asset manager is building digital-asset exposure across both major tokens as it expands its regulated product lineup, with Fidelity's FETH and Morgan Stanley's MSSE also contributing while Grayscale's ETHE shed $7.4 million.
