HedgeCo.Net — U.S. spot Bitcoin ETFs recorded about $159.5 million of net inflows on September 17, 2026, according to Farside Investors data cited by Gate News, Bloomingbit, and Lookonchain on September 18. BlackRock’s IBIT led with about $183.7 million of inflows. The same session’s spot Ethereum ETFs posted about $39.3 million of net outflows, with BlackRock’s ETHA about ?$42.9 million.
The print reverses the prior session’s already-published tape: on September 16, spot BTC and ETH ETFs together lost about $520 million. Allocators should treat September 17 as a one-day Bitcoin rebound alongside continued Ether redemptions rather than a broad crypto-ETF risk-on day. Farside remains the primary flow source of record for issuer-level U.S. spot ETF prints.
This is finalized daily flow data, not a fundraise. Mark the ~$159.5 million BTC inflow, IBIT’s ~$183.7 million lead, ETH’s ~$39.3 million outflow / ETHA ~?$42.9 million, and the contrast to September 16’s ~$520 million combined outflows as sourced. Do not invent price targets or multi-day streak claims beyond the published tape.
