Bitcoin ETFs See $606M Inflow, Biggest One-Day Haul Since May 1

U.S. spot Bitcoin (BTC) exchange-traded funds pulled in $606.29 million of net inflows on Aug. 20, extending their streak to four straight sessions of additions. It was the category's largest single-day intake since May 1. Spot Ethereum (ETH) ETFs also stayed in demand, taking in $221 million on the day and likewise notching a fourth consecutive session of inflows. The buying came as bitcoin traded around $75,524, supported by a broad crypto rally that has carried through the week. Bitcoin ETFs have now logged daily inflows of $297.56 million (Aug. 17), $189.30 million (Aug. 18), $517.19 million (Aug. 19) and $606.29 million (Aug. 20). Over the four-day run, cumulative net inflows for spot Bitcoin ETFs rose to $53.40 billion. The last larger one-day inflow for the group was on May 1, when the funds attracted $629.73 million and total net assets topped $100 billion for the first time. On Aug. 20, BlackRock's iShares Bitcoin Trust (IBIT) led the pack with $502.99 million, accounting for more than 80% of the day's total. The week's advance has been accompanied by a wave of short liquidations, pressuring bearish positions across the market. Ethereum ETFs have tracked the same pattern. The category recorded $189.15 million on Aug. 19—its biggest single-day inflow in 10 months—before adding another $221 million on Aug. 20. The parallel four-day streaks point to institutions building exposure to both assets rather than rotating between them. Trading activity also picked up. Total value traded across Bitcoin ETFs reached $5.41 billion on Aug. 20, while total net assets stood at $90.16 billion. Attention now turns to whether the inflow momentum holds into next week; after four straight sessions of buying, a pause in the rally could invite profit-taking.
