According to @EricBalchunas, generic listing standards now render the 19b-4 filings and their statutory clock meaningless for this product class, leaving only the S-1 registrations awaiting a formal green light from the SEC Division of Corporation Finance, which he says shifts the timing focus to final S-1 effectiveness for potential listing triggers (source: Eric Balchunas on X, Sep 29, 2025, link: https://twitter.com/EricBalchunas/status/1972779124679975004). According to @EricBalchunas, issuers have submitted amendment number 4 for the Solana spot ETF S-1, which he interprets as the process entering its final stage with approval odds now at 100 percent (source: Eric Balchunas on X, Sep 29, 2025, link: https://twitter.com/EricBalchunas/status/1972779124679975004). According to @EricBalchunas, the listing could come any day and he advises market participants to be ready, implying near-term headline sensitivity for SOL once Corp Finance issues the formal green light on the S-1s (source: Eric Balchunas on X, Sep 29, 2025, link: https://twitter.com/EricBalchunas/status/1972779124679975004).
