CoinEx News: U.S. spot Bitcoin ETFs, funds that hold BTC for investors, ended the first half of 2026 with about $5.47 billion in net outflows based on monthly flow data. March and April added $3.29 billion, but May and June erased that rebound with $6.94 billion in exits; June alone lost $4.51 billion, while H1 trading volume still reached $408.94 billion.

The signal is not weak activity, but active selling through ETF wrappers: net assets fell from $106.96 billion in January to $70.95 billion in June, keeping BTC exposed to institutional redemption pressure even when headline trading demand looks busy.
