The U.S. SEC has indicated that issuers of spot Bitcoin ETFs can submit their final 19b-4 filings, which are proposals for rule changes on stock exchanges, as soon as Friday. SEC commissioners are expected to vote on these filings next week. Additionally, issuers need SEC approval for their S-1 filings and ETF prospectus documents. The approval of 19b-4 and S-1 forms may not occur simultaneously, with a gap of days expected between them. Once the S-1 is approved, trading can commence on the next business day. BlackRock, Fidelity, Grayscale, VanEck, Valkyrie, and 21Ark have made recent filings. Bloomberg analyst Eric Balchunas commented that the 19b-4 filings might not pass until Jan. 10 and S-1 approvals could extend to Jan. 16 or later.
