All 12 US Spot Bitcoin ETFs Bleed on May 15 — $290M Out as Ethereum ETFs Hit Fifth Straight Day of Outflows!

U.S. spot Bitcoin ETFs recorded a combined net outflow of $290 million on May 15, according to SoSoValue data — and the damage was uniform: not a single one of the 12 tracked funds posted a net inflow on the day. That kind of across-the-board selling pressure is rare and signals broad institutional de-risking rather than rotation between products.

U.S. spot Ethereum ETFs added another $65.65 million in net outflows, extending their losing streak to five consecutive days. The persistence of the Ethereum outflow run suggests the selling isn't noise — it's a directional shift in sentiment across both major crypto ETF categories simultaneously.

For macro-aware investors, a clean sweep of outflows across all 12 Bitcoin ETFs on the same session — with no offsetting bid anywhere in the product set — is the kind of data point that warrants attention regardless of where spot prices are trading.
