Solana spot ETFs saw $39.22 million in net inflows over the past week, reflecting strong institutional interest in this layer-1 blockchain's investment products. While Bitcoin spot ETFs hold much larger balances, Ethereum ETFs experienced $7.7 billion in outflows last year, with some of that capital likely moving into Solana products. Regulatory uncertainty remains as the SEC has sent mixed signals on Solana ETF approvals, though Polymarket estimates an 87% chance of approval in 2025. Investors are rotating into Solana amid these dynamics, but regulatory risks could impact future inflows.
