Bitcoin ETF Inflows Lag in 2026 Despite Faster Rebound Than Altcoins

U.S. spot Bitcoin ETFs have recovered nearly two-thirds of recent outflows while Ethereum products reclaimed only one-third, reinforcing BTC dominance near $79,000. After a six-week inflow streak totaling $3.4 billion ended with large May withdrawals, flows turned mixed with Morgan Stanley-led rebounds and sovereign buying from Mubadala. Overall 2026 ETF inflows remain below prior years amid elevated Treasury yields and regulatory optimism around the CLARITY Act. The divergence highlights institutional preference for Bitcoin over altcoins during a volatile period.
