Digital asset treasuries
Bitcoin bought by companies that hold it as a treasury reserve, from their SEC filings, next to the Bitcoin moved on-chain. Days are in UTC.
Treasury buying
Weeks: Monday to Sunday, UTC. A filing gives one total for several days, so it is spread evenly over those days.
Share of PEV: Bitcoin bought divided by PEV over the days a company has reported. Days it hasn't reported yet are left out. Combined adds up the companies' shares.
Not counted as bought: Bitcoin that came with a merger, such as Semler Scientific's into Strive in January 2026.
Bitcoin that Strategy and Strive report buying in SEC filings, and its share of PEV on the same days.

Strategy
Strategy's estimated daily buying from STRC trading, and the securities that paid for the bitcoin it reports.
Method change: Probable Economic Volume (PEV) used to count US market hours only. It now covers the full 24-hour UTC day, so it compares STRC buying with all the Bitcoin moved that day, and the absorption rate reads lower than on earlier days.
