On September 21, 2026, Bitcoin ETFs recorded $999.0 million in net inflows, while Ethereum ETFs added $270.0 million and Solana ETFs saw $26.0 million in inflows. Hyperliquid ETFs also registered positive flows of $2.9 million. The pattern reflects sustained investor appetite across multiple crypto asset classes through spot and futures vehicles.
The scale of Bitcoin inflows dwarfed other asset flows on the day, representing concentrated interest in the largest cryptocurrency by market capitalization. Ethereum's secondary position aligns with its typical depth in the ETF market. Solana and Hyperliquid, smaller by comparison, still demonstrated measurable demand.
It remains unclear what drove the inflows—whether broad macro conditions, specific news events, or seasonal patterns—or whether the flows persisted beyond this single trading day.
