Summary
Bitcoin and Ethereum spot exchange-traded funds continued to attract investor capital on May 4, 2026, with data from SoSoValue showing sustained demand for cryptocurrency exposure through regulated investment vehicles. Bitcoin spot ETFs recorded a $532 million net inflow, marking the third consecutive day of positive flows and signaling resilient institutional participation in the spot Bitcoin market. This multi-day inflow pattern reflects ongoing confidence in direct Bitcoin holdings through the ETF structure.
Ethereum spot ETFs demonstrated similarly positive momentum, capturing $61.3 million in total net inflows for the same trading period. BlackRock's ETHA led inflows with $54.8 million for the day, though the product maintains a historical cumulative net outflow position of $45.3 million. This divergence suggests recent investor rebalancing or renewed interest in the ETHA product after earlier redemptions. Fidelity's FETH claimed the second-largest inflow contribution at $6.5 million and significantly outperforms the broader category on a historical basis, with cumulative net inflows totaling $2.30 billion since inception.
The Ethereum spot ETF complex has now accumulated $12.08 billion in total historical net inflows, with current assets under management reaching $13.97 billion. This represents meaningful institutional integration, with Ethereum spot ETFs comprising 4.93% of the asset's total market capitalization. The concentration ratio and cumulative flow data underscore the strategic importance of regulated spot ETFs as distribution mechanisms for institutional cryptocurrency allocation, particularly as providers compete for market share in what remains a maturing asset class.
