Two sources have reported that issuers of potential Ethereum ETFs were given less than 24 hours to complete the final 19b-4 forms. However, even if these forms are officially approved, it may still take several weeks before spot ETH ETFs can begin trading. Unlike with Bitcoin ETFs, where S-1 registration statements were prepared in advance and exchanges were ready, the recent 180-degree turn by the SEC means that preparation and approval may not happen as quickly as anticipated. If the 19b-4 forms are approved, the market may not be significantly impacted by the approval of S-1 forms within a few weeks, as the listing would already be guaranteed.
