BlackRock's spot Bitcoin ETF has flipped from seller to buyer, pulling roughly $250 million of BTC over the past two days after more than two consecutive weeks of daily net selling, according to on-chain analytics tracked by Arkham.
Why it matters
BlackRock's IBIT has been the single largest institutional venue for spot BTC exposure since launch, and a 14-day run of net outflows had become one of the defining supply-side stories of the cycle. The reversal matters less for the dollar figure and more for the signal: the dominant bid on the tape is back in accumulation mode rather than distribution. The flip also arrives at a moment when broader spot ETF flow data had begun to turn cautious, making the largest issuer turning back to buys a notable read on positioning.
Market impact
The two-day $250 million haul is modest in absolute terms compared to IBIT's early-cycle single-day prints, but the regime change is the story. A sustained return to net buying from the issuer that set the floor on the way in would re-establish institutional accumulation as a structural force, not a one-day flow event. Watch the next several sessions for confirmation that the bid sticks rather than fades.
