Bitcoin spot ETFs saw $389.71 million in net outflows, while Ethereum spot ETFs recorded $2.26 million in net outflows, according to the latest weekly ETF flow data. Solana and XRP spot ETFs posted net inflows of $10.26 million and $2.25 million, respectively.

The weekly figures showed investors taking different approaches across major cryptocurrency investment products. Bitcoin spot ETFs recorded $389.71 million in net outflows, marking the largest weekly withdrawal among the major crypto ETFs. Ethereum spot ETFs also finished the week in negative territory, posting $2.26 million in net outflows. In contrast, Solana and XRP spot ETFs attracted fresh capital, highlighting continued investor interest in selected altcoin investment products. Spot crypto ETFs, which hold the underlying tokens directly rather than tracking derivatives, have become a primary channel for regulated exposure to digital assets since US-listed Bitcoin funds launched in January 2024, with Ethereum equivalents following in July of that year and Solana and XRP products listed in 2025. Because share creations and redemptions are backed by the underlying assets, weekly flow figures are widely tracked as a gauge of where institutional capital is moving.

Solana and XRP Buck the Trend

While Bitcoin and Ethereum funds experienced withdrawals, Solana spot ETFs recorded $10.26 million in net inflows, making them the strongest performers of the week. XRP spot ETFs added $2.25 million in fresh inflows, extending institutional exposure to Ripple-related investment products despite broader weakness in the crypto ETF market. The contrasting flows suggest investors were selectively allocating capital rather than reducing exposure across the entire digital asset sector. Even so, the combined $12.51 million inflow into Solana and XRP funds remains small relative to Bitcoin's $389.71 million outflow, underscoring the scale gap between the newer altcoin products and the far larger Bitcoin ETF market.

Institutional Allocation Remains Selective

The latest weekly ETF flows indicate that institutional positioning remains mixed. Although Bitcoin experienced significant outflows, demand for Solana and XRP products demonstrates that investors continue to seek opportunities beyond the two largest cryptocurrencies. Market participants will be watching upcoming ETF flow data to determine whether the divergence persists or if capital rotates back into Bitcoin and Ethereum funds.
