U.S. spot Bitcoin ETFs attracted about $66.2 million on Tuesday, extending their net-inflow streak to nine sessions. The nine-session total was described as exceeding $3.1 billion, while the existing record calculated cumulative inflows through Sept. 29 at about $3.08 billion, creating a discrepancy between the rounded new figure and the earlier tally. The run narrowly surpassed August's nine-session streak, which drew roughly $3.04 billion, although daily inflows slowed sharply from $999 million on Sept. 21. Ether and Zcash products moved in the opposite direction, with both ending their inflow streaks. Bitcoin traded near $84,400, below its September high near $87,350. The current run remains shorter than the 13-session streak recorded in June 2025. Spot Bitcoin ETFs provide brokerage-based exposure to Bitcoin without requiring investors to purchase or custody the asset directly, making their flows a closely watched sentiment indicator.
