Bitcoin and ether ETFs in the U.S. saw record monthly outflows as prices fell sharply on Monday.

U.S. Bitcoin and Ether ETFs See Largest Outflows Since November as Prices Fall

U.S. spot bitcoin (BTC$88,457.49) and ether (ETH$2,961.55) ETFs experienced a combined $582 million in net outflows on Monday, marking the largest withdrawals since November 20, as crypto markets fell and bitcoin dropped to $85,100.

Bitcoin ETFs accounted for $357.6 million of the outflows, the heaviest in nearly two weeks, while ether ETFs saw $224.8 million redeemed, extending a three-day streak of withdrawals, according to Farside data.

Historically, Mondays have been weaker for bitcoin. Velo data shows it is the third-worst performing day of the week over the past 12 months, trailing only Thursday and Friday, with several of bitcoin’s local lows in 2025 occurring on Mondays.

A key level to watch is the U.S. ETF cost basis, representing the average entry price of bitcoin held by ETFs. At roughly $83,000, it has previously supported rebounds during lows on November 21 and December 1, per Glassnode.

Among bitcoin ETFs, Fidelity Wise Origin Bitcoin Fund (FBTC) led outflows with $230.1 million, followed by Bitwise Bitcoin ETF (BITB) at $44.3 million and ARK 21Shares Bitcoin ETF (ARKB) at $34.3 million. BlackRock’s iShares Bitcoin Trust (IBIT) reported no net flows.

For ether ETFs, iShares Ethereum Trust (ETHA) accounted for the bulk of redemptions, with $139.1 million withdrawn.
