ETF data shows Bitcoin dominance held firm in 2025 as Ethereum gradually gained share
Bitcoin maintained 70-85% of the 2025 crypto ETF market share while Ethereum slowly grew its allocation to 15-30%.Summary
Throughout 2025, Bitcoin firmly dominated the institutional crypto ETF market, consistently holding between 70% and 85% of the total market share, reflecting its status as the primary entry point for institutional investors. This strong concentration provided consistent price support for Bitcoin.
Ethereum captured the second-largest allocation, gradually increasing its share from the start of the year to reach 15-30% by December, signaling growing institutional comfort, though it remains significantly behind Bitcoin. While overall spot Bitcoin ETF volumes compressed in the final weeks of December, public treasury accumulation of ETH accelerated aggressively, driven almost entirely by a single corporate entity, BitMine Immersion (BMNR), utilizing an ATM equity strategy to fund its ETH purchases.
Long-tail assets like XRP, SOL, LINK, LTC, and DOGE held negligible market share, largely because their respective ETF products were only approved late in 2025 and are still in their early lifecycle.
