The honeymoon is officially over for spot Bitcoin ETFs. After a record-breaking debut in January 2024 and two years of near-uninterrupted capital inflows, the products have hit a wall in 2026, with net flows turning negative for the majority of the year so far.
The numbers tell an uncomfortable story
US spot Bitcoin ETFs recorded $5.4 billion in net outflows during the first half of 2026, marking the first negative half-year since the products launched.
To put that in context: these same funds had accumulated $56.6 billion in cumulative net inflows over their first two years of existence.
June 2026 was particularly rough. The month produced roughly $4.5 billion in outflows, the largest single-month exit on record for spot Bitcoin ETFs.
