Overview
- U.S. spot Bitcoin ETFs recorded a $233.13 million net inflow on July 30 with BlackRock’s IBIT providing roughly $183 million of that lift, according to multiple flow trackers.
- The next trading day those gains flipped as ETFs posted about $265.4 million in net outflows on July 31, with IBIT accounting for roughly $122.7 million of the withdrawal.
- IBIT’s size is central to the move: it held roughly 739,066 BTC and about $46–48 billion in net assets around late July, so its creations or redemptions move large amounts of actual Bitcoin.
- ETF mechanics matter because authorized participants create shares by buying Bitcoin and redeem shares by selling Bitcoin, which means concentrated client flows into or out of a single issuer can force sizable spot buying or selling.
- Data providers differ on July and July‑to‑date totals but all show 2026 flows remain deeply negative overall, many ETF buyers sit far below their cost basis, and the market stays fragile to concentrated flows and macro signals.
