U.S. spot Bitcoin ETFs attracted approximately $731 million in net inflows on September 3rd. Reports on September 4th confirmed this as the largest single-day inflow since January. BlackRock’s iShares Bitcoin Trust (IBIT) led the market with $454 million in new capital. This contribution accounted for more than 60% of the total daily net inflow.

The capital surge coincided with Bitcoin’s price climbing back above the $80,000 threshold. This movement signaled a sharp reversal from September 1st, when IBIT experienced a $201 million outflow. Market analysts attribute the price rally partly to traders closing short positions. The scale of the IBIT inflow further indicates a strong trend of institutional accumulation.
