Spot Bitcoin (CRYPTO: BTC) ETFs experienced a significant influx, attracting around $2.4 billion between September 21 and September 25, 2026, marking their strongest week of the year, according to SoSoValue. However, Bitcoin ETF inflows declined each day during this period—starting at $999 million on September 21 and dropping to $134 million by September 25.

As of September 26, Bitcoin was trading near $84,000, up 3.3% over the past week. With both the overall inflow and the price looking robust, Bitcoin holders may wonder which signal to trust: the impressive $2.4 billion total or the dwindling daily amounts.

The latest data shows that Spot Bitcoin ETFs, which hold bitcoin and trade like stocks, saw net inflows—money coming in minus money going out—every trading day. Nonetheless, each day’s contribution was smaller than the previous one.
