Bitcoin ETFs See $450M Outflow as Senate Vote Fails

U.S. crypto exchange‑traded funds (ETFs) experienced a sharp reversal on Tuesday, September 15, as investors withdrew $450.33 million from bitcoin ETFs – the largest single‑day outflow since June 25. The sell‑off coincided with the Senate’s failure to advance the Digital Asset Market Clarity Act and a dip in bitcoin’s price below $76,000.

Bitcoin ETF Outflows

All major bitcoin ETFs recorded net redemptions. Fidelity’s FBTC led the withdrawals with $214.75 million, followed by BlackRock’s IBIT ($161.69 million) and Grayscale’s GBTC ($44.14 million). Smaller funds such as Ark & 21Shares’ ARKB and Bitwise’s BITB lost $17.38 million and $12.36 million respectively. No bitcoin ETF posted an inflow. Total trading value for the sector rose to $4.35 billion, while net assets fell by nearly $5 billion to $95.72 billion.

Ether ETFs Follow Suit

Ether‑linked ETFs also saw net outflows of $141.47 million. BlackRock’s ETHA accounted for $97.97 million of the exits, with Bitwise’s ETHW ($34.40 million), Grayscale’s ETHE ($17.47 million) and Fidelity’s FETH ($7.18 million) also losing capital. A few inflows occurred, notably BlackRock’s ETHB (+$12.38 million), 21Shares’ TETH (+$2.40 million) and Morgan Stanley’s MSSE (+$776,050). Ether ETF trading value reached $1.99 billion, and net assets declined to $15.42 billion.

Solana ETFs Remain Positive

Solana‑focused ETFs were the only major category with net inflows, attracting $1.35 million, all of which went to Bitwise’s BSOL. Trading value for solana ETFs was $81.20 million, with net assets ending at $1.38 billion.

Other Crypto ETFs

• HYPE ETFs lost $3.89 million, entirely from Bitwise’s BHYP, leaving net assets at $407.53 million.
• XRP ETFs recorded no net flows, maintaining net assets at $1.41 billion.

Regulatory and Monetary Context

The Senate cloture motion on the Digital Asset Market Clarity Act failed 49‑50, falling short of the three‑fifths threshold needed to advance the legislation. Market participants are now looking ahead to the Federal Reserve’s rate decision, with futures markets indicating a roughly 90 % probability of a quarter‑point increase. The Fed’s guidance could influence bitcoin positioning as institutional investors react to regulatory uncertainty and tighter financial conditions.
