French company Capital B, which is building a bitcoin reserve, has purchased 376 bitcoins ($BTC) for 25.3 million euros ($29.5 million), bringing its total holdings to 3,521 $BTC.
The purchase was financed after Capital B raised approximately 30.1 million euros ($35 million), including a private placement backed by investors Adam Back and TOBAM, according to a statement released on Monday.
The company acquired the bitcoins at an average price of 67,182 euros per coin; Swissquote Bank Europe facilitated the transaction, and Taurus provided custody.
In total, Capital B has spent 309.4 million euros to build its bitcoin reserve at an average cost of 87,878 euros per $BTC. According to BitcoinTreasuries.net, following this purchase, the company now ranks 25th among public companies in terms of bitcoin holdings.
This latest acquisition is the largest for Capital B since September 2025, when the company bought 551 $BTC for 54.7 million euros. Additionally, the company holds 61 $BTC for operational purposes; these assets are held separately from the treasury reserves and are not included in performance metrics related to bitcoin.

Leading companies with $BTC reserves continue to accumulate
While companies such as K Wave Media and Sequans Communications have begun reducing their bitcoin reserves, others continue to accumulate the asset.
Japanese Metaplanet acquired 2,823 $BTC in the second quarter for approximately $222 million, bringing its holdings to 43,000 $BTC. During the quarter, the company paid an average of about $78,850 per bitcoin and now ranks third among public corporate bitcoin holders—after Michael Saylor's Strategy and Twenty One Capital, according to BitcoinTreasuries.net.
In August, Sweden-based H100 Group more than tripled its bitcoin holdings after acquiring Norwegian companies that owned 2,455 $BTC. The all-stock transaction increased H100's reserve to 3,506 $BTC, which at the time made it the second-largest public corporate bitcoin holder in Europe. Capital B's latest purchase puts it 15 $BTC ahead of H100, although both companies still trail Germany's Bitcoin Group SE, which holds 3,605 $BTC.
Strategy, the world's largest corporate bitcoin holder, also resumed purchases in August after a two-month pause, acquiring 4,603 $BTC for $370 million. This brought its holdings to 845,050 $BTC, acquired for a total of $63.3 billion.
