US spot Bitcoin ETFs recorded more than $1.7 billion in net inflows over a two-day period, Cointelegraph reported on September 23, 2026. The inflows came as Bitcoin moved above investors’ estimated average cost basis, a level that reflects the average price at which holders acquired the asset. The report links the ETF activity with Bitcoin’s move above that estimated holder cost basis, placing both developments at the center of the latest market update. The data concerns US spot Bitcoin exchange-traded funds and Bitcoin itself; it does not provide a fund-by-fund breakdown or specify the exact two-day dates in the supplied material. Bitcoin is the primary asset covered by the report, while the ETF flows offer a measure of recent net demand through US-listed spot products.
