Capital B adds 376 Bitcoin in $29M purchase, boosting holdings to 3,521 BTC

French Bitcoin treasury company Capital B has acquired 376 Bitcoin (BTC) for 25.3 million euros ($29.5 million), bringing its total holdings to 3,521 BTC.

The purchase was funded after Capital B completed roughly 30.1 million euros ($35 million) in capital raises, including a private placement backed by investors Adam Back and TOBAM, according to a Monday announcement.

The company bought the Bitcoin at an average price of 67,182 euros apiece, with Swissquote Bank Europe executing the purchase and Taurus providing custody.

Capital B has spent a total of 309.4 million euros acquiring its Bitcoin treasury, at an average cost of 87,878 euros per BTC. The purchase moved the company to 25th among publicly traded companies by Bitcoin holdings, according to BitcoinTreasuries.net.

The latest acquisition was Capital B’s largest since September 2025, when it purchased 551 BTC for 54.7 million euros. The company also holds 61 BTC for operational purposes, which it keeps separate from its treasury reserve and excludes from its Bitcoin-related performance metrics.

Top BTC treasury firms continue accumulating

While companies including K Wave Media and Sequans Communications have moved to unwind their Bitcoin treasuries, others are continuing to accumulate.

Japan-based Metaplanet acquired 2,823 BTC during the second quarter for about $222 million, bringing its holdings to 43,000 BTC. The company paid an average of roughly $78,850 per Bitcoin during the quarter and now ranks as the third-largest publicly traded corporate Bitcoin holder, behind 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 holding 2,455 BTC. The all-share deal lifted H100’s treasury to 3,506 BTC, making it Europe’s second-largest publicly traded corporate Bitcoin holder at the time. Capital B’s latest purchase puts it 15 BTC ahead of H100, though both remain behind Germany’s Bitcoin Group SE with 3,605 BTC.

Strategy, the world’s largest corporate Bitcoin holder, also resumed buying in August after a two-month pause, acquiring 4,603 BTC for $370 million. The purchase brought its holdings to 845,050 BTC, acquired for a combined $63.3 billion.
