US spot Bitcoin ETFs vacuumed up $714.7 million on September 22, while their Ethereum counterparts added roughly $162 million. Combined, that’s nearly $877 million in fresh capital flowing into crypto ETFs in a single trading session, translating to over 7,000 BTC and 67,000 ETH worth of net buying.

The numbers cap off a four-day inflow streak that has funneled between $2.1 billion and $2.3 billion into these products since September 17. That stretch started just days after Bitcoin ETFs hemorrhaged over $450 million in redemptions on September 15.

BlackRock’s IBIT led the Bitcoin ETF charge with $350.3 million in net inflows, roughly half the day’s total. Fidelity’s FBTC followed at $257.4 million, and Morgan Stanley’s MSBT contributed $99 million.

On the Ethereum side, BlackRock’s ETHA topped the leaderboard at $88.1 million, with Fidelity’s FETH pulling in $33.6 million and Grayscale’s mini trust adding $27.3 million.

The bigger picture in numbers

Cumulative net inflows into US spot Bitcoin ETFs now sit at approximately $56.9 billion. Total assets under management across the category have climbed to roughly $110.8 billion to $111 billion, representing about 6.4% of Bitcoin’s entire market capitalization.

Just one day earlier, on September 21, Bitcoin ETFs recorded $999 million in net inflows, setting a single-day record for 2026. Bitcoin itself was trading above $86,000 during this period, having briefly punched through $87,000 — levels the asset hadn’t touched since January.
