BlackRock has again updated the filing for its iShares Bitcoin Premium ETF, with Bloomberg ETF analyst Eric Balchunas saying the product, identified in the older topic as the iShares Bitcoin Premium Income ETF with ticker BITA, has now filed a third amended S-1. The latest amendment still does not disclose the fund’s fee, suggesting BlackRock is continuing to refine the product’s structure and disclosures before a potential launch. Balchunas also said BlackRock may be positioning the fund to launch before Goldman Sachs’ Bitcoin ETF, which he said is expected in about six weeks. The update comes as BlackRock’s spot Bitcoin ETF IBIT reached $54 billion in assets under management, with Balchunas saying its first 18 months set the fastest pace of ETF inflows on record.
