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).

According to @EleanorTerrett, two weeks ago the SEC approved generic listing standards that remove the need for exchanges to file 19b-4s for individual token ETFs, streamlining and accelerating listings, source: @EleanorTerrett on X, Sep 29, 2025. She reports that if a token meets existing criteria, the SEC can approve a crypto ETF at any time via an S-1 filing, meaning looming deadlines for individual ETFs are no longer the gating factor for timing, source: @EleanorTerrett on X, Sep 29, 2025. Trading takeaway: headline and gap risk can now materialize on any day; monitor issuer S-1 amendments, SEC effectiveness notices, and exchange listing alerts as primary catalysts for liquidity and volatility in related token markets and ETF proxies, source: @EleanorTerrett on X, Sep 29, 2025.

According to Eric Balchunas, the SEC has approved generic listing standards that clear the way for spot crypto ETFs to launch under the 1933 Act without case-by-case hurdles, provided the underlying asset has futures on Coinbase (source: Eric Balchunas/X, Sep 17, 2025). Balchunas notes that roughly 12–15 coins currently meet the Coinbase-futures condition, indicating a pipeline of eligible spot ETF products tied to those assets (source: Eric Balchunas/X, Sep 17, 2025). For traders, the key watchpoints are issuer 1933 Act filings and Coinbase-futures eligible coins for upcoming spot ETF listing activity following this approval (source: Eric Balchunas/X, Sep 17, 2025).
