Bitcoin ETFs Attract $2.3 Billion in Just Four Days: Can the Momentum Carry Into Q4?

Bitcoin (CRYPTO:BTC) ETFs saw an impressive influx of about $2.3 billion over four trading days through September 22, 2026. This surge included $999 million on September 21 and $715 million on September 22, according to SoSoValue. These inflows have pushed Bitcoin ETFs back into the green for the year, with a positive balance of about $320 million after significant withdrawals in the first half of the year.

As of September 25, Bitcoin is trading at $84,362, still down 3.3% for 2026. This begs the question: can Bitcoin ETFs maintain their buying momentum as we head into the fourth quarter, or was this recent activity just a temporary spike?

Bitcoin ETFs Took In About $2.3 Billion Over Four Trading Days

The influx of money occurred on September 17, 18, 21, and 22, coinciding with Bitcoin’s surge above $86,000. During this period, the fund purchased over 26,000 Bitcoin with the newly added capital. Each dollar of inflow translates to Bitcoin purchases, as a designated trading firm called an authorized participant transfers cash to the fund in exchange for new shares, allowing the fund to buy more coins.
