The report says U.S. spot Bitcoin ETF funds have recorded their longest inflow run this year, with combined holdings approaching 7% of Bitcoin’s circulating supply.
U.S. spot Bitcoin ETFs have reached their longest inflow streak of 2025, according to the source, signaling sustained investor demand for regulated Bitcoin exposure through exchange-traded funds. The report adds that these funds now hold close to 7% of Bitcoin’s supply, a notable benchmark because ETF accumulation can tighten available market liquidity while giving traditional investors easier access to the asset without direct custody. The development highlights the growing role of spot Bitcoin ETFs in price discovery and institutional portfolio allocation.
