U.S. spot Bitcoin exchange-traded funds attracted $2.4 billion in net inflows for the week ending Sept. 25, marking the largest weekly inflow since October 2025. The surge pushed 2026 year-to-date net flows into positive territory after a $5.8 billion deficit in late July—a complete reversal in less than two months.

The recovery was driven by a seven-day winning streak of inflows. However, daily demand cooled sharply toward week's end, indicating that while the overall trend remained strong, capital deployment decelerated in the final trading sessions.

The renewed institutional and retail interest extended beyond Bitcoin. U.S. spot Ether ETFs recorded $690 million in net inflows during the same week, reversing a $140 million outflow from the prior week. Solana funds also attracted capital, suggesting broader confidence across major digital asset classes.

The ability to reverse a multi-billion dollar deficit within weeks points to a resilient demand base. But the daily momentum fade raises a critical question: was the seven-day streak durable conviction or tactical repositioning ahead of a consolidation phase. Future flows will reveal whether this inflow marks a sustained shift from net redemption to net accumulation or a temporary relief rally.
