U.S. spot Bitcoin ETFs extend inflow streak to eight days; August net subscriptions top $3B

ChainCatcher — U.S. spot Bitcoin ETFs posted about $232 million in net inflows on Wednesday, extending their streak of net buying to eight straight sessions, according to SoSoValue data. Total inflows over the run stand at roughly $2.8 billion. Spot Ethereum ETFs also logged net inflows for an eighth consecutive day, adding around $192 million on Wednesday and lifting cumulative inflows to more than $1 billion. Elsewhere, XRP funds took in $280 million, HYPE products recorded $150 million of inflows, and Solana funds attracted $90 million. Bitcoin ETF inflows in August have now surpassed $3 billion, the strongest month since 2026 and about double April's pace. As of Tuesday, Bitcoin ETF net assets were slightly above $99 billion, up from about $77 billion in mid-August; most of the increase reflected price gains rather than fresh capital. BlackRock's IBIT captured the bulk of new money, accounting for about 62% of Monday's total and roughly $1.3 billion last week. Despite the recent rebound, Bitcoin ETFs are still down about $2.5 billion in net flows year to date in 2026. August has recouped more than half of the outflows seen from May through July. With three trading days left in August, another roughly $160 million of net inflows would lift August above October 2025 as the biggest monthly intake since these products launched.
