Odaily Planet Daily reports that three informed sources have stated that the U.S. Securities and Exchange Commission (SEC) has requested potential Solana ETF issuers to submit amended S-1 filings within the next week. Two of the sources added that "the agency informed issuers that it will comment on the filings within 30 days after submission of the S-1 documents. The SEC requires issuers to update wording related to physical redemption and how issuers handle staking, and added that the agency appears willing to include staking as part of the Solana ETF." Another source estimated that these updates could enable the Solana ETF to be approved within three to five weeks. James Seyffart from Bloomberg Intelligence stated that he expects approval this year, possibly as early as July. Seyffart wrote in a report this week, "We believe the SEC may now focus on handling Solana's 19b-4 application and staking ETFs earlier than planned. Issuers and industry participants may have been working with the SEC and its cryptocurrency task force to develop rules, but the agency’s final decision deadline for such applications is not until October."
