According to U.Today, the future of spot Solana exchange-traded funds (ETFs) in the United States remains uncertain. This speculation arises after the Chicago Board Options Exchange (CBOE) removed the 19b-4 filings for Solana ETFs submitted by VanEck and 21Shares from its website. In June, New York-based investment firm VanEck filed a proposal to launch a spot Solana ETF in the U.S., aiming to provide direct exposure to SOL. The shares were to be valued daily using prices from trading platforms selected by MarketVector. Shortly after, 21Shares also filed a similar proposal with the U.S. Securities and Exchange Commission (SEC). Despite these efforts, senior Bloomberg ETF analyst James Seyffart and other experts speculated that approval was unlikely until 2025. However, the broader crypto community remained hopeful for a positive outcome. The recent removal of the filings from the CBOE website has cast doubt on the future of Solana ETFs in the U.S. It is unclear whether the SEC rejected the filings or if the asset managers retracted them. Notably, the SEC has not acknowledged the filings since their submission. ETFStore President Nate Geraci commented on the situation, suggesting that the Solana ETF might not be approved under the current administration. Meanwhile, the first Solana ETF is set to launch in Brazil. The Brazilian Securities and Exchange Commission (CVM) approved the offering about two weeks ago, generating excitement among the crypto community in the region.
