Value now multiplies the filed count by the live perpetual mark price ($77K); it is not a company figure. Counts are shown only where the filing's own fair value per coin is plausible; companies that tag fair value without a count show the value alone.
What this data is
Bitcoin treasuries
Since the 2025 accounting change (ASU 2023-08) US companies carry bitcoin at fair value and tag the count, the fair value and the cost in their quarterly and annual filings. That makes the holdings of every listed treasury company a primary-source number: it comes from the balance sheet the company signed, not from a press release or a wallet-tracking estimate.
This page reads those tags from the SEC's XBRL company facts for a maintained list of filers. Companies tag the coin count under different unit names and a few misplace the scale, so the count shown for each company is the newest one whose fair value per coin sits within a wide band of the market price; where the count cannot be reconciled or was never tagged, the fair value alone is shown and the count is marked as not reported.
The numbers lag the real position by up to a quarter, because a 10-Q is filed weeks after quarter end and purchases in between are announced on 8-Ks that carry no structured data. Strategy, the largest holder, buys weekly; its filed count is the floor, not the current figure. The page states the as-of date next to every row for that reason.

How to read it
- Read the as-of date first. A count dated 30 June is the quarter end, and anything bought since is not in it.
- Fair value less cost is the unrealized gain the company reports; cost per coin (cost divided by count) is the average price the treasury was built at.
- A company whose count is marked not reported still holds bitcoin: divide its fair value by the price on the as-of date for a rough count, and expect the company's own 8-K to be more current.
