Invesco and Galaxy Digital have filed an S-1 registration statement with the U.S. Securities and Exchange Commission (SEC) for a spot Solana (SOL) exchange-traded fund (ETF). This filing marks the ninth application from asset managers seeking to launch a Solana ETF, indicating growing institutional interest in the cryptocurrency. Invesco and Galaxy Digital collectively manage over $400 billion in assets under management (AUM). The ETF proposal has been submitted to the Cboe BZX Exchange under Rule 14.11(e)(4) for Commodity-Based Trust Shares, including features such as staking and in-kind redemption. The Cboe BZX has also filed for regulatory approval to list and trade the Invesco Galaxy Solana ETF. This development comes amid a competitive landscape where multiple issuers, including VanEck, Franklin Templeton, Grayscale, 21Shares, and Bitwise, have filed or updated their S-1 applications for spot Solana ETFs. VanEck manages over $116 billion in assets, and Franklin Templeton is among four issuers to have submitted amended registration statements recently. The filings underscore an intensifying race among institutional investors to offer regulated exposure to Solana, reflecting broader demand for altcoin investment products.
