Bitcoin ETFs Log Their Worst Session Since June
The selloff hit every major fund. Fidelity’s FBTC led with $214.8 million in withdrawals, followed by BlackRock’s IBIT at $161.7 million and Grayscale’s GBTC at $44.1 million, according to Decrypt. Taken together, Tuesday marked the heaviest single-day Bitcoin ETF outflow since June 24 — a session that echoed the worst week on record for these funds earlier this year.
Total reported U.S. spot Bitcoin ETF outflows for the session reached $450.4 million, a single-source figure from Decrypt that the available evidence does not independently corroborate at the fund-data level. For related coverage, see Bitcoin ETFs See Worst Week on Record as Outflows Surge.
The losses extended well beyond Bitcoin. Ethereum ETFs shed $142.3 million in the same session, bringing combined Bitcoin, Ethereum, and XRP ETF outflows to roughly $593 million for the day. That combined figure puts Tuesday alongside the multi-asset $1.26 billion outflow week that rattled these products earlier this year.

Why the Failed Clarity Act Vote Shook Market Sentiment
The backdrop was a procedural defeat in the U.S. Senate. On September 15, Senate vote 234 failed 49-50, blocking cloture on the motion to proceed to H.R. 3633, the Digital Asset Market Clarity Act. Sixty votes were needed to advance the bill. For related coverage, see Bitcoin Spot ETFs Post $296M Weekly Outflow, March 23–27 | Ethereum ETF Data.
H.R. 3633 would have established a joint SEC and CFTC regulatory framework for the offer and sale of digital commodities, according to the official Senate roll-call index. Its supporters pitched it as the first comprehensive attempt to resolve the longstanding jurisdictional dispute between the two agencies over crypto assets.

The vote and the ETF outflows occurred in the same news cycle. The available evidence establishes timing, not causation; broader market conditions may have also contributed. But a one-vote defeat for the most significant digital-asset bill in years is exactly the kind of policy shock that prompts institutional money to move to the sidelines. Prior Bitcoin ETF outflow episodes have coincided with regulatory uncertainty in Washington, reinforcing that pattern.
What Investors Will Watch Next for Bitcoin ETFs
The immediate question is whether Tuesday’s outflows represent a one-session reaction or the start of a sustained withdrawal trend. Earlier weekly outflow episodes this year reversed quickly once the triggering uncertainty faded; whether that holds depends partly on whether the Clarity Act finds a path forward in the Senate.
No confirmed timeline for a revote or amended bill currently exists. The one-vote margin suggests potential, but Senate scheduling and shifting coalition dynamics make the next procedural step unclear. Bitcoin was trading at $76,425 at press time, with the Crypto Fear & Greed Index at 50, a Neutral reading that suggests the market has not yet tipped into full panic mode.
The Senate came one vote short of opening debate on the most significant crypto regulatory bill in years. Is that close enough to revive — or does it signal the coalition simply isn’t there?
