Bitcoin ETFs Post $450M in Outflows After Senate Blocks Clarity Act Move

U.S. spot Bitcoin ETFs suffered their steepest one-day outflows since June 24, as selling pressure hit the major funds across the board. Fidelity's FBTC recorded $214.8 million in withdrawals, followed by BlackRock's IBIT with $161.7 million and Grayscale's GBTC with $44.1 million, according to Decrypt. Decrypt reported total U.S. spot Bitcoin ETF outflows of $450.4 million for Tuesday's session. Available evidence supports the timing of the outflows, but the figure cannot be independently corroborated at the fund-data level and does not establish a causal link to the day's policy news. The risk-off move extended beyond Bitcoin. Ethereum ETFs were reported to have lost $142.3 million in the same session, putting combined Bitcoin, Ethereum, and XRP ETF outflows at roughly $593 million for the day. That total echoes the multi-asset $1.26 billion outflow week that unsettled these products earlier this year. Policy backdrop: the Senate failed to clear the procedural hurdle to advance the Digital Asset Market Clarity Act. On September 15, Senate vote 234 failed 49–50, blocking cloture on the motion to proceed to H.R. 3633. Sixty votes were required. According to the official Senate rollcall index, H.R. 3633 would have set a joint SEC and CFTC framework governing the offer and sale of digital commodities. Supporters framed it as the first comprehensive effort to resolve the long-running jurisdictional dispute between the two agencies over crypto assets. The failed vote and the ETF outflows unfolded in the same news cycle. The evidence shows coincidence in timing rather than proven causation, and broader market conditions may have contributed. Still, a one-vote setback for one of the most consequential digital-asset bills in years is the type of policy surprise that can prompt institutions to reduce exposure. Prior Bitcoin ETF outflow episodes have also coincided with heightened regulatory uncertainty in Washington. Investors now face a key question: was Tuesday's move a one-session reaction, or the start of a more persistent withdrawal trend. Several earlier weekly outflow episodes this year reversed quickly once the uncertainty faded; whether that pattern holds may depend on whether the Clarity Act finds a path forward in the Senate. There is currently no confirmed timeline for a revote or an amended bill, and despite the narrow margin, scheduling and shifting coalitions leave the next step unclear. Bitcoin was trading at $76,425 at press time. The Crypto Fear & Greed Index stood at 50, or "Neutral," suggesting sentiment had not shifted into outright panic.
