Potential spot Ethereum ETF issuers are responding to comments received from the Securities Exchange Commission (SEC) last week regarding the S-1 form and plan to file a response by this Friday. Sources described the comments as "minor" and "reasonable" and expect approval soon. In May, issuers filed preliminary drafts of the S-1 form after their Form 19b-4 was approved, but it took the SEC two weeks to provide feedback. Bloomberg senior ETF analyst Eric Balchunas expects the product could go live in early July. SEC chairperson Gary Gensler said the approval time depends on how quickly issuers respond to feedback. Analysts predict that the flow of Ethereum ETFs could reach 20% of the Bitcoin ETF.
