Bitcoin ETFs just had their roughest single-day outflow since June, and the timing was hard to miss. U.S. spot Bitcoin ETFs recorded $450 million in net withdrawals on Tuesday after the Senate failed to advance the Digital Asset Market Clarity Act.
According to SoSoValue, it was the largest daily outflow since June 25. Bitcoin also fell after the vote, though its reaction looked relatively restrained compared with the damage across several major altcoins.
The Senate motion fell short of the 60 votes needed to move forward, landing at 49–50. Seven Democrats who had spent months negotiating the legislation also voted against advancing it, adding another layer of uncertainty around the bill.
Bitcoin was down 1.7% over 24 hours, while the CoinDesk 20 Index was nearly flat after falling 4.6% on Tuesday in its sharpest decline since June 5. For an asset class that can move violently on policy headlines, the contrast between Bitcoin and some altcoins was notable.
Bitcoin ETFs Retreat as Regulatory Pressure Hits Altcoins
The selloff became more pronounced among tokens with greater exposure to U.S. regulatory questions. Stellar fell 9.6% over 24 hours, while XRP dropped 8.1%. Of the assets tracked in the CoinDesk 100, 95 posted losses during that period.
Traditional markets, meanwhile, barely flinched. Nasdaq 100 futures gained 0.33%, gold rose 0.88% and silver advanced 1.37%. The Dollar Index was unchanged.
The focus is now moving toward the Federal Reserve, which is scheduled to announce its interest-rate decision later Wednesday. Going into the meeting, an increase had been the market’s base case.
The failure of the Clarity Act also changes the legislative timetable. The bill’s defeat effectively removes the prospect of comprehensive crypto market-structure legislation clearing the Senate this year, with Congress expected to be under split control in January.
Bitcoin’s derivatives market added another warning sign. More than $570 million in leveraged futures positions were liquidated over the previous 24 hours as prices fell, marking the largest wave of forced deleveraging since Aug. 22.
Shorts also gained ground in taker activity, accounting for 51.5% of trading volume over 24 hours. On Hyperliquid, the long-to-short ratio slipped to 2.53 from 2.71, still leaving more than two long positions for every short.
Bitcoin futures open interest climbed to 688,000 BTC from 676,000 BTC even as the asset declined 1.4%. That combination can indicate traders are adding bearish positions as prices fall. The 24-hour open-interest-adjusted cumulative volume delta was negative as well, showing aggressive short execution in the market.
Yet not every derivatives signal pointed in the same direction. Perpetual funding rates still reflected optimism among some traders, while 30-day implied volatility for both Bitcoin and ether remained within recent ranges and well below their yearly highs.
Options traders, however, appeared increasingly interested in protection against further downside. Bitcoin’s one-week options skew rose to around 5.76%, while the one-month measure reached about 6.33%. Ether options showed a similar pattern.
Trading volume offered a more mixed picture. Bitcoin’s most heavily traded options over the previous 24 hours were predominantly calls, led by the $79,000 strike. Ether was different, with its five most-traded options all being puts.
Bitcoin ETFs Feel the Shock While a Few Tokens Break Away
Even in a broad selloff, there were exceptions. Arbitrum jumped 16% after Standard Chartered projected a potential $10 price by the end of 2030, roughly 70 times its current level. The bank pointed to expected revenue from Robinhood Chain and expanding tokenized-asset activity, while assigning a much more restrained $0.50 target for the end of this year.
Synapse delivered an even stranger move, more than doubling to $0.1787 without an obvious catalyst. Its market data suggests leverage played a major role: futures volume reached $310.64 million over 24 hours against a market capitalization of just $41.18 million, while open interest represented about 60% of the token’s value.
Privacy tokens also continued to attract attention. Zcash gained 6.9% to $1,186.75, leading the sector, while Dash rose 2.9%.
Perpetuals exchange token Lighter climbed 6% to $4.27, and Raydium added 5.4% to $1.30 as both recovered part of Tuesday’s losses. DeFi names AAVE, JUP and ETHFI, however, remained under pressure, each falling more than 2% after midnight.
For Bitcoin ETFs, the $450 million withdrawal tally is the clearest sign that the Senate vote changed the market’s mood. Bitcoin itself absorbed the shock with a smaller decline, but the broader reaction showed just how quickly regulatory headlines can travel from Washington into crypto portfolios, derivatives desks and some of the market’s most exposed tokens.
