Exchange-traded funds (ETFs) experienced record outflows, losing $671.9 million, as Bitcoin’s price continued to slide post-Federal Reserve meeting, dropping below $100,000.

U.S.-listed spot Bitcoin (BTC) ETFs saw unprecedented withdrawals on Thursday, with the CME futures premium falling into single digits, signaling reduced short-term demand. Investors ended a 15-day streak of inflows by pulling $671.9 million from the 11 Bitcoin ETFs, marking the largest single-day outflow since their launch on January 11, based on data from Coinglass and Farside Investors.

Fidelity’s FBTC and Grayscale’s GBTC were the main contributors to these outflows, losing $208.5 million and $188.6 million, respectively. Other funds also experienced outflows, with BlackRock’s IBIT ETF seeing its first zero inflows in weeks.

Bitcoin’s value continued its downward trend on Thursday, dipping to $96,000, a nearly 10% drop from the all-time high of $108,268 reached earlier this week.

This bearish sentiment was reflected in the derivatives market, where the annualized premium on the CME’s one-month regulated Bitcoin futures fell to 9.83%, the lowest in over a month, according to Amberdata.

A decrease in the premium indicates that cash-and-carry arbitrage strategies, which involve holding long positions in ETFs and shorting CME futures, are less profitable than before. As a result, the demand for Bitcoin ETFs may remain weak in the short term.

Additionally, Ether ETFs recorded a net outflow of $60.5 million, the first since November 21. Ether’s price has fallen by 20% since surpassing $4,100 prior to Wednesday’s Federal Reserve decision.
