Bitcoin ETFs post biggest outflow since jan.; Solana inflows

Spot Bitcoin ETF (exchange-traded funds) recorded $635.23 million in outflows on May 13, the largest single-day withdrawal since Jan. 29. The outflow was part of two consecutive days of net redemptions that left weekly flows at negative $841.19 million, according to SoSoValue data.

Between May 1 and May 6, Bitcoin ETFs attracted $1.68 billion before four days of outflows and a modest $27.29 million inflow on May 11. April was the strongest month of 2026 for Bitcoin funds, with net inflows of $1.97 billion. The six weeks before the recent outflows brought roughly $3.4 billion into spot Bitcoin products, the longest positive streak since July 2025. BlackRock’s iShares Bitcoin Trust accounted for a large share of that earlier inflow activity.

Ethereum funds recorded three consecutive days of outflows during the same period. Among other large-cap altcoin ETFs, XRP products logged three days with no flows in May. Dogecoin ETFs posted only three small inflow days, while Chainlink funds showed four modest inflow days.

Solana-based ETFs have had a different pattern. Solana funds have not reported any outflow days in May and collected $90.83 million across eight positive sessions and one flat day. Within the altcoin ETF group, Solana led in both the frequency and size of inflows for the month to date.

New listings also saw early interest. 21Shares’ Hyperliquid (HYPE) ETF, which launched on May 12, drew $2.52 million over its first two sessions and maintained positive flows through its initial trading days.

The recent outflows interrupted a multi-week run of institutional inflows to spot crypto ETFs that began earlier in the year. For now, weekly net flows sit at negative $841.19 million as of the May 13 reporting period.
