BITCOIN TREASURY: CAPITAL B
How much Bitcoin does Capital B own?
A company listed in Paris that has been buying Bitcoin since November 2024 with money raised from investors. It announces each purchase with a running total, so the history below has a point for every one it has announced. It also keeps a small amount of Bitcoin for its day-to-day needs, apart from that total. The company leaves those coins out of its figures, and so does this page.
Capital B Bitcoin held
Every day since the first disclosure. The line steps because the company reports a running total, not individual purchases, and the dashed marks are its most recent reported changes.
Right now
3,525 Bitcoin. That is the most recent total Capital B has reported, as of Sep 14, 2026.
That was 7 days ago. Until the company reports again, this is the most recent thing it has said.

Why does the line sit flat for weeks at a time?
Because a treasury only changes on paper when the company says it changed. Capital B reports a running total rather than each purchase, so the history moves in steps, and a step covers everything that happened between one report and the next.
A flat stretch is not missing data. It is the company not having filed anything new, which is most weeks for most companies.

What this page counts
Capital B is a public company that holds Bitcoin on its own balance sheet. Every number on this page comes from a filing the company made to its regulator, on the date it made it, so this is what Capital B said about itself rather than an estimate of what it owns.
Why the line runs flat between filings
A treasury only changes when the company reports a change. Between filings the line runs flat, which is not missing data: it is the most recent thing the company has told anyone.
Why the history moves in steps
Capital B reports a running total rather than each individual purchase. That is why the history moves in steps, and why a step covers everything that happened between one report and the next rather than a single day's buying.
Why the dollar figures are dated
The dollar figures are the coins valued at one day's price, and that day is stated beside them. It runs a day behind the holding itself, because the price calendar and the filing calendar are not the same calendar, and pretending they were would date a number to a day it does not belong to. How these figures are put together.
