Grayscale filed a prospectus and, according to earlier reporting, a second amended S-1 registration statement for a spot BNB ETF, while VanEck submitted a similar amendment to its own BNB ETF proposal on May 15, according to Bloomberg ETF analyst James Seyffart. Seyffart said the coordinated filings may reflect responses to SEC feedback and could signal progress in the review process. If approved, Grayscale’s product could become the first U.S. spot ETF offering direct exposure to BNB. Separately, Canary Capital also amended its proposal for a staked TRX ETF, underscoring how issuers are broadening U.S. crypto ETF efforts beyond Bitcoin and Ethereum into altcoin and yield-linked products.
