Bitcoin and Ethereum ETFs Face $345M Outflows Amid Selective Altcoin Inflows

Key Insights:

• Bitcoin ETFs sold nearly seven days of mined BTC supply as institutional investors reduced large-cap crypto exposure.
• Ethereum ETFs recorded over $121 million in outflows while XRP and LINK funds posted positive daily inflows.
• Altcoin ETF demand remained selective as Solana, Chainlink, and HYPE products attracted fresh institutional capital.

Crypto ETF outflows intensified on May 28 as institutional investors reduced Bitcoin and Ethereum exposure while selective altcoin products continued attracting steady capital inflows.

Crypto ETF outflows accelerated after U.S. spot Bitcoin ETFs sold 3,114 BTC yesterday. The combined outflows reached nearly $228.88 million during the trading session. Market participants tracked another heavy distribution day across institutional investment products.

The update shared on X showed Bitcoin funds maintaining persistent selling pressure. ETF issuers sold almost seven days of mined Bitcoin supply yesterday. That selling activity added pressure across broader digital asset markets.

BlackRock recorded the largest Bitcoin ETF reduction during the session. The company sold approximately 2,420 BTC valued near $177.94 million. Institutional traders monitored the move closely because of BlackRock’s market influence.

Fidelity Investments, Grayscale Investments, and Valkyrie Investments also reported notable Bitcoin sales. Fidelity sold 261 BTC during the session yesterday. Grayscale reduced another 357 BTC from its Bitcoin holdings.

Crypto ETF outflows also affected Ethereum investment products during the same session. U.S. spot Ethereum ETFs recorded outflows exceeding 60,160 ETH yesterday. The total Ethereum selling reached approximately $121.35 million.

BlackRock again represented the largest source of Ethereum ETF selling activity. The firm sold roughly 38,310 ETH valued near $77.28 million yesterday. Institutional investors remained cautious despite Ethereum’s expanding tokenization narrative.

Fidelity also reduced Ethereum exposure by approximately 7,470 ETH during the session. Grayscale sold another 14,380 ETH worth nearly $29.01 million yesterday. Ethereum products therefore experienced broad institutional selling rather than isolated fund activity.

Previous trading data already showed large Ethereum ETF withdrawals across the market. The latest session extended that trend into another trading day. Traders continued evaluating whether demand could stabilize after recent outflows.

Crypto ETF outflows remained concentrated mainly within Bitcoin and Ethereum investment products. Several altcoin ETFs still attracted positive inflows during the same session. That divergence reflected selective institutional capital rotation across digital assets.

XRP ETFs added approximately 1.34 million XRP yesterday. The inflows represented nearly $1.77 million in fresh institutional demand. XRP products therefore outperformed several larger digital asset funds.

Solana ETFs also recorded positive inflows during the trading session. Solana products added nearly 5.88K SOL valued around $484,370 yesterday. Investors continued monitoring institutional interest surrounding high-performance blockchain networks.

Chainlink and HYPE ETFs also posted positive daily inflows yesterday. Meanwhile, Litecoin, Polkadot, Hedera, Avalanche, and Dogecoin recorded zero ETF flows. Total U.S. spot crypto ETF outflows finished near $345.27 million overall.
