Bitcoin ETFs see $770M in inflows – Is September breaking its curse?

As the crypto tokens saw fresh rallies in August 2026, the ETF market was no exception. Carrying ahead this bullish sentiment. Spot Bitcoin [BTC] ETFs recorded $730.8 million in net inflows on the 3rd of September, the strongest single-day inflow since the 14th of January.

On this day, BlackRock’s IBIT alone absorbed about $454 million, followed by ARK 21Shares’ ARKB at about $137.7 million and Fidelity’s FBTC at $74.4 million. There were smaller inflows into several other funds, while VanEck and WisdomTree saw modest outflows.

Is 2026 September slightly different from previous years?

Well, the month of September, which has historically been known to be unlucky for the crypto market, especially Bitcoin, has so far favored BTC.

It was only on the 1st of September that BTC ETFs saw approximately $236.5 million of net outflows. On 2nd September, however, things changed as the ETFs recorded $101 million of inflows and then the huge $730.8 million inflow on 3rd September.

On 4th September, too, the ETFs added another $174.6 million, bringing the four-day period to approximately $770 million of net inflows despite the large 1st September withdrawal.
