U.S. Bitcoin spot ETFs recorded $630 million in net inflows on May 1, according to SoSoValue data, marking a strong single-session print as institutional appetite shows no sign of cooling. Ethereum spot ETFs added $101 million on the same day, a meaningful figure for a product category that has historically lagged its Bitcoin counterpart.
The simultaneous inflow across both asset classes is notable — it suggests buyers aren't rotating between <a class="ticker-mention" href="/en-US/token/btc">BTC</a> and <a class="ticker-mention" href="/en-US/token/eth">ETH</a> but adding exposure to both. When demand broadens like this across the two majors, it typically reflects a structural allocation shift rather than a tactical trade.
Combined, the two products absorbed over $730 million in a single session — a reminder that regulated ETF wrappers are steadily becoming the dominant on-ramp for institutional crypto capital.
