Golden Finance reported that the cryptocurrency prediction platform Polymarket previously stated that the probability of the U.S. Solana ETF being listed in 2025 is about 77%. Matthew Sigel, director of research at VanEck, said the forecast was "underestimated." In June 2024, VanEck and rival asset manager 21Shares sought permission from U.S. regulators to list the spot Solana ETF. In November, shortly after Trump won the US presidential election, Matthew Sigel said the likelihood of US approval of the SOL ETF in 2025 was "extremely high".
