BlackRock’s clients just added another 1,495 Bitcoin to their collective holdings, a purchase worth roughly $115.45 million routed through the iShares Bitcoin Trust (IBIT). It’s the kind of transaction that barely raises eyebrows anymore, which is itself remarkable given that barely two years ago, a spot Bitcoin ETF didn’t even exist in the US.
IBIT’s gravitational pull
IBIT has captured roughly 75% of new capital flowing into US spot Bitcoin ETFs in recent months. In one week in August 2026, IBIT pulled in $1.33 billion in investments. A single trading day on July 30/31 saw $183.41 million flow into the fund, which represented 79% of total daily flows across all spot Bitcoin ETFs.
As of late August, IBIT managed approximately $59 billion in assets under management. For a product that launched in January 2024, it has become the largest US spot Bitcoin ETF by assets. The broader US ETF sector saw $3.3 billion in Bitcoin-related inflows in August alone.
Client-driven, not proprietary
