The core substance of the claim is supported by the primary SEC filing, Form S-1 for iShares Bitcoin Premium Income ETF. That filing explicitly states the trust seeks bitcoin exposure while providing premium income through an actively managed strategy of writing (selling) call options on IBIT shares and sometimes on indices tracking spot bitcoin ETPs including IBIT. Yahoo Finance's BlackRock Files With SEC to Launch iShares Bitcoin Premium Income ETF independently describes the same mechanism and attributes it to the SEC filing. However, the specific ticker claim 'BITA' is not established by the SEC filing; the fetched filing names the vehicle iShares Bitcoin Premium Income ETF and the Yahoo report notes that initial registrations can omit details like tickers. So the statement is likely true in substance, but the exact ticker/name framing in the title is not fully verified from the primary source.
