Spot Bitcoin (CRYPTO:BTC) ETFs opened 2026 with heavy selling pressure, recording a combined $681 million in net outflows during the first full trading week of the year.
The outflows marked a sharp reversal from early January inflows, signalling a shift in investor sentiment as broader risk appetite weakened.
Data from SoSoValue showed that spot Bitcoin ETFs posted four consecutive days of net redemptions between Tuesday and Friday.
The largest single-day outflow occurred on Wednesday, when investors pulled approximately $486 million from the products.
Selling pressure continued on Thursday with a further $398.9 million in outflows, followed by $249.9 million on Friday.
These losses outweighed strong inflows earlier in the week that had briefly lifted optimism around spot Bitcoin ETFs.
On January 2, spot Bitcoin ETFs attracted $471.1 million in net inflows, suggesting renewed interest at the start of the year.
Another $697.2 million flowed into the products on January 5, before sentiment quickly reversed.
The abrupt change reflected growing caution across markets as expectations for near-term US interest rate cuts faded.
