Bloomberg ETF analyst Eric Balchunas mentioned on May 30 that U.S. spot Ethereum ETFs could launch by the end of June, following updated filings from BlackRock and Grayscale. He noted a "legit possibility" for a late June launch but considered a mid-June launch unlikely. The latest expected launch date is July 4.

Balchunas' prediction is based on the timing of issuers’ S-1 statements, highlighting BlackRock’s May 29 amendment, which lacked final details like fees, suggesting it’s nearly complete. Grayscale also submitted an S-3 amendment on May 30, clarifying its prohibition on staking. These steps are among the last required before the funds can begin trading.

Balchunas believes the SEC's timing is politically motivated, having already achieved its goal of not appearing anti-crypto by not rejecting the ETFs. Industry figures like Ark Invest CEO Cathie Wood and Coinbase analyst David Han share this view.

The SEC has asked other applicants to submit draft S-1 filings by May 31 for initial comments, requiring further amendments if necessary. Apart from BlackRock and Grayscale, only VanEck has submitted amendments since the SEC's initial approvals on May 23. Bloomberg ETF analyst James Seyffart expects the SEC will take weeks or months to approve the S-1 statements.
