Senate Crypto Vote Sends Nearly $593 Million Fleeing ETFs

WASHINGTON — spot Bitcoin ETFs lost $450.4 million on Tuesday, their steepest single-day outflow since June 24, after the U.S. Senate rejected the Digital Asset Market Clarity Act. Fidelity’s Wise Origin Bitcoin Fund (FBTC) led withdrawals at $214.8 million, followed by BlackRock’s iShares Bitcoin Trust (IBIT), the largest spot Bitcoin fund by assets, with $161.7 million in redemptions.

Grayscale’s Bitcoin Trust (GBTC), which converted to an ETF in early 2024, recorded an outflow of $44.1 million. Funds managed by ARK Investment Management and Bitwise Asset Management also experienced minor net withdrawals.

The Senate voted 49 to 50 against invoking cloture on the Clarity Act, well below the 60 votes required to bypass procedural hurdles and move the bill to a formal floor debate. The defeat effectively ends the prospect of comprehensive cryptocurrency market-structure legislation passing through Congress in 2026.

Spot Ethereum ETFs, launched in July 2024 following regulatory approvals, lost another $142.3 million during Tuesday’s session. Newer and smaller investment vehicles tracking XRP held flat, one day after recording $11.3 million in inflows.

Across Bitcoin, Ethereum, and XRP products, the single-day outflow neared $593 million, the sharpest market-wide retrenchment since June. That month was the worst overall period of capital flight for Bitcoin funds on record, driven by shifting global macroeconomic outlooks. Spot cryptocurrency ETFs, which have become a primary barometer of institutional sentiment, bore the immediate impact of the political gridlock in Washington.

Senator Cynthia Lummis (R-WY) spearheaded the bill, which was intended to create a clear regulatory framework for digital assets in the United States. It would have divided oversight between the Securities and Exchange Commission (SEC) and the Commodity Futures Trading Commission (CFTC), a long-standing point of contention within the industry. The proposal also sought to define which digital assets qualify as commodities and which are securities, effectively normalizing crypto trading for institutional market participants such as pension funds and commercial banks.

Lummis declared the legislative effort “over” for the year after the vote. “The Democrats are now anti-American. Sad,” she wrote on the social media platform X. Senator Elizabeth Warren (D-MA), the ranking Democrat on the Senate Banking Committee and a prominent critic of the digital asset industry, led the opposition on the Senate floor. Warren warned that the Clarity Act could weaken consumer protections and potentially “spark a crypto-fueled economic crash.”

The legislative collapse on Tuesday sent a chill through institutional markets, while investors were also focused on an impending Federal Reserve monetary policy decision. Financial markets are pricing in a high probability of a rate hike, which would be the first upward adjustment in borrowing costs in three years. Historically, higher rates dampen investor appetite for speculative and volatile assets like cryptocurrencies.

Spot Bitcoin ETFs were approved by the SEC in January 2024 after years of regulatory resistance. The retreat was not confined to Bitcoin, as the combined outflow from the three asset categories approached $593 million in one session.

Without federal legislation clarifying regulatory boundaries, the U.S. digital asset market remains in regulatory uncertainty. For years, the industry has operated under a “regulation-by-enforcement” paradigm dominated by legal battles brought by the SEC under existing securities laws.

Only 22 working days remain on the Senate calendar before lawmakers pivot to midterm campaign efforts, making an immediate revival of the Clarity Act highly unlikely. The Digital Chamber, a prominent Washington-based crypto advocacy organization, nevertheless described the Senate vote as a temporary “setback” rather than a permanent defeat.

In the absence of congressional action, administrative agencies will again be responsible for defining the rules of the road for the digital asset sector. U.S. Treasury Secretary Scott Bessent has previously indicated that the SEC and CFTC’s administrative rulemaking processes will serve as the primary regulatory roadmap for the remainder of 2026, leaving digital asset firms to navigate a patchwork of agency guidelines rather than a codified statutory framework.
