Spot Bitcoin and Ether ETFs in the U.S. added about $452 million in net inflows on September 23, extending a run of fresh allocations into regulated crypto products. Bitcoin ETFs absorbed roughly $347 million, while Ether ETFs took in about $105 million. BlackRock led both categories: its iShares Bitcoin Trust, IBIT, attracted $166 million, close to half of all Bitcoin ETF inflows for the day, while its iShares Ethereum Trust, ETHA, brought in about $50.8 million, also nearly half of the Ether total.
Demand stayed strong, but much of it flowed into the biggest name in the field. That leaves the headline positive for crypto ETF demand overall, while also showing that this session’s buying was not broadly spread across issuers.
