The difference between BTC, ETH, and SOL spot ETFs is evident not only in scale but also in investment models. Bitcoin ETFs lead the institutional market with an asset size of approximately $94 billion, standing out due to their high liquidity and store-of-value narrative. Ethereum ETFs have reached a size of $12 billion and differentiate themselves through smart contracts and staking yields. Solana ETFs attract attention with an asset size of approximately $1.3 billion and cumulative net inflows exceeding $1.4 billion. Their staking-focused structure provides a significant advantage. The key divergence in 2027 will not be based on fund size, but on the sustainability of capital inflows. While BTC will continue to serve as the foundational crypto asset in institutional portfolios, the decisive factor in the competition between ETH and SOL will be the economic value generated by their networks—and how effectively that value translates into investor demand—rather than staking yields alone.
