Summary
U.S. spot Ethereum ETFs demonstrated continued institutional buying momentum on August 28, 2026, recording $102.1 million in net inflows and extending their inflow streak to 10 consecutive trading days. Concurrently, U.S. spot Bitcoin ETFs reversed course, posting $201.9 million in net outflows and ending a nine-day inflow period, according to data reported by Decrypt and attributed to SoSoValue. The divergence between the two leading cryptocurrency ETF categories underscores shifting capital allocation patterns within the institutional digital asset space.
The reversal in Bitcoin fund flows occurred against the backdrop of cooling momentum in Bitcoin's price rally toward $80,000, triggered by hawkish remarks delivered at Jackson Hole. This suggests that institutional investors may have capitalized on Bitcoin's recent strength to reduce exposure or reallocate capital, while simultaneously maintaining appetite for Ethereum-based investments. The data reflects net flows into and out of U.S.-listed spot crypto ETF categories, rather than changes in underlying asset valuations.
Bitcoin spot ETFs maintain substantially larger cumulative inflows and asset bases compared to Ethereum peers. Bitcoin ETF cumulative net inflows total approximately $55.1 billion with total net assets of roughly $93.9 billion as of August 28. By contrast, Ethereum ETF cumulative inflows stand at approximately $12.9 billion with total net assets of $13.8 billion, reflecting the significant disparity in institutional capital concentration between the two markets. Despite the smaller absolute flows, Ethereum's 10-day inflow streak outlasts Bitcoin's recent nine-day run, indicating relative strength in near-term demand for Ethereum exposure among ETF investors.
