US spot Bitcoin exchange-traded funds (ETFs) recorded their weakest performance in nearly a year after posting $1.33 billion in net outflows last week. The data comes from SoSoValue and covers a shortened four-day trading period.
The sharp pullback marks the worst weekly showing since February 2025. It also reflects a sudden shift in investor sentiment after Bitcoin ETFs attracted $1.42 billion in net inflows the previous week.
Selling pressure peaked in the middle of the week. On Wednesday alone, investors pulled $709 million from Bitcoin ETFs, the largest single-day outflow of the week. Tuesday followed with $483 million in redemptions, while outflows slowed on Thursday and Friday.
The scale of the losses mirrors the volatility seen in late February 2025, a period often referred to as the “February Freeze.” During that week, Bitcoin ETFs lost $2.61 billion as Bitcoin prices fell sharply from above $109,000 to below $80,000.
BlackRock’s iShares Bitcoin Trust (IBIT) led the declines. The fund posted outflows on all four trading days, with the heaviest redemptions occurring on Tuesday and Wednesday. IBIT currently holds around $69.75 billion in net assets, equal to about 3.9% of Bitcoin’s circulating supply.
Despite the recent setback, the long-term picture remains strong. Since their launch in January 2024, US spot Bitcoin ETFs have recorded $56.5 billion in cumulative net inflows, with total assets across all funds reaching roughly $115.9 billion.
Ethereum ETFs also faced selling pressure. Spot Ether ETFs saw $611 million in net outflows for the week, reversing the previous week’s $479 million inflows. Wednesday was the worst day, followed by heavy redemptions on Tuesday.
Not all crypto ETFs struggled. Spot Solana ETFs continued to attract demand, posting $9.6 million in net inflows and extending their positive trend. In contrast, spot XRP ETFs ended the week with $40.6 million in net outflows.
The ETF sell-off comes as on-chain data signals a broader market shift. According to CryptoQuant, Bitcoin holders have started realizing net losses for the first time since October 2023, a pattern that has often appeared during past transitions from bull to bear markets.
