Bitcoin ETFs Shed $450M in Largest Outflow Since June as CLARITY Act Fails

What happened: Spot Bitcoin ETFs recorded a $450.4 million net outflow on September 15, marking the largest single-day withdrawal since June 24. Fidelity’s FBTC led with -$214.8M, followed by BlackRock’s IBIT (-$161.7M), Grayscale’s GBTC (-$44.1M), ARKB (-$17.4M), and BITB (-$12.4M). The outflow coincided with a 2.5% drop in BTC price and the failure of the CLARITY Act to advance in the U.S. Senate, falling short in a 49-50 cloture vote. Four Republican senators joined all Democrats in voting no, effectively stalling the bill.

Why it matters: The sharp reversal from a $159.9M inflow the previous day underscores the fragility of institutional sentiment amid regulatory uncertainty. The failed CLARITY Act vote removes a potential regulatory tailwind for crypto markets, contributing to weakening U.S. demand as reflected in both ETF flows and spot pricing. Industry lobbyists remain hopeful for a revived bill, but the setback signals ongoing legislative headwinds for digital assets in the U.S.
