VanEck's Mathew Sigel believes Solana ETFs could arrive sooner than expected, contrasting with BlackRock's view that it is premature. Solana has challenged Ethereum on scalability and fees, now entering the ETF debate. Sigel highlights Europe's existing ETPs, aiming for US leadership. Regulatory changes, potentially under a new SEC chair, could ease ETF approvals. BlackRock's Robert Mitchnick remains skeptical, citing maturity and investability issues. Hester Pierce, SEC Commissioner, echoes regulatory caution. Only VanEck and 21Shares have filed for Solana ETFs, despite the asset's recent market decline.
