Summary
U.S. spot cryptocurrency ETFs posted a combined net outflow of $51.11 million on August 28, 2026, according to data from SoSoValue, with Bitcoin ETF outflows driving the entire market-wide decline. Spot Bitcoin ETFs shed $201.81 million, terminating a nine-trading-day inflow streak that had begun on August 17. This reversal occurred despite significant price appreciation in Bitcoin, which gained 20.2% to $77,846 during the month ending August 28, compared to $64,780 on July 30.
The outflow from Bitcoin ETFs contrasted sharply with continued inflows into competing cryptocurrency products. Spot Ether ETFs attracted $102.18 million, extending their consecutive inflow streak to ten trading days. XRP ETFs drew $26.2 million, while Solana ETFs posted $18.08 million in inflows and Hyperliquid ETFs added $4.48 million. Over the past 30 days, Solana ETFs captured $193.41 million and Hyperliquid ETFs accumulated $64.5 million, with certain altcoins appreciating as much as 44.9% during this period.
Despite the daily outflow, institutional capital allocation over the preceding 30 days remained heavily weighted toward established cryptocurrency assets. Spot Bitcoin and Ether ETFs combined for $5.06 billion in net inflows, representing approximately 92% of the roughly $5.51 billion in total inflows to the spot crypto ETF market. Bitcoin ETFs individually pulled in $3.27 billion, while Ether ETFs drew $1.79 billion. Price performance across major tokens corresponded with fund flows, with Ether gaining 27.3% to $2,443 and XRP advancing 27.8% to $1.38 over the same period.
The divergence between outflows in Bitcoin products and inflows into altcoin vehicles signals evolving investor positioning within institutional crypto portfolios, even as capital concentration remains centered on the two largest cryptocurrency assets by market capitalization.
