VanEck, 21Shares, and Canary Capital have asked the US Securities and Exchange Commission (SEC) to return to the ‘first-to-file’ principle for exchange-traded fund (ETF) approvals.

Bloomberg ETF analyst James Seyffart says the SEC delay in a decision on Ether staking and XRP ETFs was not unexpected.

Nasdaq has filed with the SEC to list 21Shares spot Sui ETF, joining Canary Capital as the only other issuer bidding to launch a similar product.

Seven Solana ETF filings hit the SEC, including new entries and amendments from major issuers. Analysts say staking language in the filings could complicate approval timelines.
