BlackRock has submitted a third amended S-1 filing for its iShares Bitcoin Premium Income ETF (BITA), according to Bloomberg ETF analyst Eric Balchunas, who flagged the update on X. While fees have not yet been disclosed, the successive rounds of amendments signal that BlackRock is actively refining the product ahead of what appears to be an approaching launch.

A third S-1 amendment is a meaningful milestone in the ETF registration process. Multiple rounds of amendments typically indicate ongoing dialogue between the issuer and the SEC — with each revision addressing regulatory feedback or updating product terms. The fact that BlackRock is on its third iteration suggests the process is maturing rather than stalling.
