VanEck is sticking with its Solana ETF plans even though Cboe Global Markets has removed the 19b-4 regulatory filings for the VanEck Solana ETF from its website. Matthew Sigel, head of digital asset research at VanEck, confirmed that VanEck's recruitment document (S-1) is still valid even though the filings are no longer visible. Cboe had filed an application with the Securities Exchange Commission (SEC) in July seeking to list the Solana ETF on its exchange and had asked the SEC to make a decision by March. Sigel said VanEck believes that Solana (SOL) is similar to Bitcoin (BTC) and Ethereum (ETH) and is a commodity rather than a security, and will continue to work with exchange partners to advance this plan.
