13F stock ownership research
ARK 21Shares Bitcoin ETF (ARKB) institutional holdings and quarterly fund activity
This reverse-ownership view starts with ARKB and shows every matching position in SnowballHare's tracked 13F manager universe. It connects holder-level changes with four-quarter history and company research without presenting delayed filings as live ownership.
Deterministic analysis from filing data
ARKB holder activity in the latest 13F cycle
Institutional positioning in ARKB is visible through the named holders. 1 active managers reported $150.6M in aggregate value. ARK Invest is the largest tracked holder. The sample is too small for a broad concentration reading.
ARKB's most visible fund moves were not evenly distributed. ARK Invest made the largest measured share-count move at -2.5%. These filings describe quarter-end positions and do not confirm what managers held after the reporting date.
The four-quarter series puts the latest holder count in context. Holder count remains near the trailing average of 1.0. Aggregate value also moves with quarter-end share prices, so dollar changes do not measure active buying by themselves.
Peer ownership data gives the holder figures a reference point. Related ownership pages include AAPL, AXP, KO. Return to ARKB stock research for financial statements, earnings, and company risks.
