As stated in the headline, this marked the fifth consecutive week of net outflows for spot Bitcoin ETFs.

IBIT and GBTC Led Weekly Outflows
The spot Bitcoin ETF with the largest net outflow last week was BlackRock’s ETF IBIT, which recorded a weekly net outflow of $355 million. Despite that weekly outflow, IBIT’s historical cumulative net inflow stood at $62.11 billion at the time of the data release.

Grayscale’s Bitcoin Trust GBTC ranked second by weekly net outflow. The product recorded a net outflow of $87.9141 million for the same period. Its historical cumulative net outflow reached $26.85 billion. Together, the weekly outflow data for IBIT and GBTC accounted for the main outflow figures highlighted in the latest spot Bitcoin ETF weekly statistics.

On the inflow side, Fidelity’s ETF FBTC posted the largest weekly net inflow among spot Bitcoin ETFs last week. FBTC recorded a net inflow of $55.6961 million during the reporting period. Its historical cumulative net inflow stood at $10.45 billion. This placed FBTC in contrast with the outflow figures reported for IBIT and GBTC during the same week.
