US-based spot Bitcoin and Ether ETFs saw a combined net inflow of $646 million on the first trading day of 2026, with Bitcoin ETFs receiving $471.3 million and Ether ETFs adding $174.5 million. This marked the largest single-day inflow for both types of ETFs in over a month.

The market decline in December impacted crypto ETFs, with investors viewing inflows as an indicator of mainstream sentiment and potential price direction. Bitcoin and Ether prices have fallen over the past 30 days amid the broader market downturn, with Bitcoin up 1.03% in the last 24 hours.

Institutional investors are reportedly “loading up” on spot Bitcoin ETFs after selling off in Q4 2025 for tax loss harvesting. Despite the year-end stumble, US investors poured over $31.77 billion into US crypto ETFs in 2025, with Bitcoin ETFs attracting the majority of net inflows at $21.4 billion.
