Bitcoin ETFs Plunge After Clarity Act Vote Fails

Bitcoin ETFs Had Their Worst Day Since June Following Failed CLARITY Act Vote

U.S. spot Bitcoin exchange-traded funds (ETFs) posted one of their sharpest single-day setbacks of the year after a key vote on the CLARITY Act failed, underscoring how policy uncertainty and a risk-off macro backdrop continue to shape flows into listed crypto products.

On Tuesday, Bitcoin, Ethereum, and XRP ETFs shed roughly $593 million combined, marking their heaviest one-day drawdown since June. U.S. spot Bitcoin ETFs were a major driver of that move, with a separate session seeing $265.37 million in net outflows, according to SoSoValue.

BlackRock’s IBIT led that day with $122.66 million in redemptions (about 1,948 BTC), followed by Fidelity’s FBTC at $54.78 million and Grayscale’s GBTC at $52.63 million.

The outflows arrived as Bitcoin traded near $63,000 to $63,650, roughly 23% below the $82,249 average cost basis for ETF holders, highlighting the pressure on investor positioning when prices sit well under aggregate entry levels.

June had already set the tone. U.S. spot Bitcoin ETFs recorded $4.5 billion in net outflows that month, the largest monthly withdrawal total since the products launched in January 2024 and about 29% above the prior record of $3.48 billion set in February 2025, according to Farside Investors. The month ended with a nine-day outflow streak, including $222.6 million withdrawn on June 30 alone, per SoSoValue.

Market participants linked the June redemptions to a mix of reduced incremental allocation to Bitcoin and broader portfolio rotation. Thomas Seiler, head of digital assets research at Standard Chartered, told The Block that “fewer new dollars are being allocated to Bitcoin,” adding that the SpaceX IPO in June pulled meaningful capital away as allocators rotated into the listing. Seiler also pointed to the lack of a near-term catalyst while crypto market structure legislation remained unresolved.

The policy backdrop became more complicated as Senate leadership confirmed there would be no floor vote on the CLARITY Act before the August recess, putting the U.S. crypto market structure debate on hold for the summer. White House adviser Patrick Witt told Semafor that a failed Sept. 15 Senate vote could leave the bill stranded for years, with odds markets reflecting reduced confidence in near-term passage. Polymarket has shown shifting expectations, including 28% odds of passage in 2026 in one snapshot and lower odds cited elsewhere.

Macro conditions have also weighed on risk assets. The Federal Reserve held rates at 3.50%–3.75% for a fifth consecutive meeting and signaled that cuts are not imminent. Three Fed presidents—Neel Kashkari, Lorie Logan, and Beth Hammack—dissented in favor of a 25-basis-point hike, and the 30-year Treasury yield jumped above 5.20%, its highest since 2007. In that environment, borrowing costs remain elevated and risk appetite often compresses, which can reduce demand for higher-volatility exposures.

Fund-flow data beyond ETFs has shown similar pressure. CoinShares reported $1.07 billion in weekly outflows from digital asset investment products in a May 18 report—its first negative week in seven and the third-largest weekly outflow of 2026—with $982 million attributed to Bitcoin withdrawals.

At the same time, ETF flows have not been one-way. U.S. spot Bitcoin ETFs also recorded periods of strong demand, including a nine-trading-day inflow streak that brought in roughly $3 billion since Aug. 17 before ending with about $201.8 million in net outflows on Aug. 28. Even with that break, the week still finished with approximately $924.5 million in net inflows, following an even stronger prior week of about $1.92 billion, the largest weekly total of 2026.

For investors and policymakers, the recent drawdowns highlight a key point: even as regulatory developments can influence long-term market structure, near-term flows into ETFs remain sensitive to price levels, macro policy, and competing capital demands—especially when legislative timelines become less certain.
