BTC: ARKB Reported Bitcoin Holdings — SEC Filings

Bitcoin holdings reported by the ARK 21Shares Bitcoin ETF (ARKB) in its original SEC 10-K and 10-Q filings, at each explicit report date.

Why use it. Track this fund's officially reported BTC holdings from one quarterly or year-end report date to the next. How to read it. Points are sparse quarterly and year-end report-date quantities, not daily, latest-hour or on-chain holdings; nothing is interpolated, forward filled or converted to USD, and no value is inferred from absent facts. SEC acceptance does not prove when figures were publicly disseminated or observed, and historical as-known availability is not claimed. Supported report dates begin March 31, 2024; this does not establish coverage from launch.

Calculation. Take each Bitcoin quantity from the fund's original SEC 10-K/10-Q filings at its explicit report date. A quantity requires a dated investment schedule Bitcoin row and Quantity of Bitcoin column; a duration context alone is not a balance, and explicit statement as-of proof sets the report date. Four reported XBRL decimals are retained. Retained periodic filings begin with the 2023-12-31 annual report, which has no supported Bitcoin balance disclosure. When later filings report a date again as a comparative, the latest SEC-accepted vintage wins and all originals stay retained.
