Public companies that keep bitcoin on the balance sheet, each number taken from the company's own filing or exchange disclosure, and every 8-K they filed that says «bitcoin», by the minute EDGAR accepted it.
1,108,595 BTC 15 companies we checked · 5.28% of 21M · stated Jun-30 to Oct-18 2026 · 3 approximate, the filing feed read through Oct-22 2026, measured and published by askthetape.com.
Some public companies keep bitcoin as a treasury asset and report it: in the US on a form 8-K or in a quarterly report, elsewhere in a notice on their own stock exchange. This page names them. The table gives each company's bitcoin as the company itself last stated it, with the date and a link to that document; together the 15 companies we have checked hold 1,108,595 BTC, 5.28% of bitcoin's 21 million cap. The list is not complete: it names only the companies we have checked so far. The total adds numbers stated on different dates, Jun-30 to Oct-18 2026, 3 of them «approximately». Under the table runs the feed of 8-K filings that say «bitcoin» from the US-listed companies we follow, newest first, stamped with the minute EDGAR accepted each one. The chart counts those filings day by day, by EDGAR's filing date, next to every 8-K on EDGAR that says «bitcoin». Numbers come from the filings themselves; we do not copy aggregators.
| leg | own poller of SEC EDGAR full-text search (form 8-K, the word «bitcoin»), deduplicated by accession number; the time of each filing is EDGAR's acceptance time, read from the filing's own header in New York time and converted to UTC. The submissions record is only a fallback: on 1 of 52 filings it carried New York digits under a UTC mark |
|---|---|
| 🩸 numbers: the document or nothing | each holding is copied from the company's own filing, press release or stock-exchange notice, and printed only after we open that document and find the number in it. Aggregator tables are a cross-check, never a source. Checked and left out, because the company states no single number for the bitcoin it holds: GameStop (GME): its 10-Q splits the coins between the balance sheet and bitcoin pledged to Coinbase, carried as a receivable, and states no total; Bullish (BLSH): it reports bitcoin only in thousands of units, wrapped bitcoin included. |
| 🩸 what is printed and how it is checked | A purchase is printed on the day it is filed when the poller's extract is marked ok, the form is an 8-K Item 8.01, and an automatic check passes (amount times average against any sum the text states, period parsed, accession present in the index, not a sale, not a quarterly total); the label beside the number says whether that extract is still «not yet reviewed» or has been «reviewed» by hand. |
| 🩸 lag | EDGAR publishes an 8-K the day it is filed, and the feed carries it on the poller's next pass. Companies outside the US report on their own exchange (Tokyo, London, Paris), not on EDGAR: their rows follow those notices and are read by hand, not by the poller. |
| policy | «as of» is the date the document gives for the number, not the day we read it. Holdings are what the company says it holds; bitcoin lent out or pledged is counted the way the company counts it. Sums add rows as of different dates. · export: whole history |
| cadence | the feed moves when the EDGAR poller runs, once an hour at :41 UTC; a filing keeps EDGAR's own acceptance time, so a late pass delays a row but never changes its time. The holdings table is checked by hand (the last check is printed above it), and a hand check older than 8 days is flagged there; since Oct-07 2026 a purchase a US company states in its 8-K (bought, average price, holdings after) also moves its row by the poller, only when the totals add up with the row before it, and the row then says «read by our poller from the 8-K, not yet checked by hand» until we check it. Daily bars count by EDGAR's filing date and stop at the last CLOSED UTC day |

latest stated purchase per company: 8 of the 15 companies 🩸 The oldest hand check in this table is 29 days old: a company may have stated a newer number since. Newest filing first. One row per company: the newest purchase from either the company's own document or its holdings line; the holdings table updates when the company states a total. A purchase whose filing states no holdings total prints «total not stated» and does not change the company's holdings row until a total is disclosed; such a row is shown only when it is newer than the holdings line. A company whose document gives no bitcoin count for a purchase is not listed (Trump Media & Technology Group: a purchase in 2026-07, amount not stated). «announced» is the day the company announced the purchase; its document does not give the trade date. Checked by hand on Sep-24 2026.
The link opens the document that states the purchase (text «SEC 8-K <accession>» for filings our poller read). The average price is the one the document gives, in its own currency, not converted. A purchase is printed the day it is filed after an automatic check of the extracted numbers; the label beside it says whether that draft has been reviewed by hand.
