Capital B Buys 376 BTC for $29M, Lifts Holdings to 3,521 BTC

French corporate Bitcoin treasury firm Capital B has added 376 BTC to its balance sheet after completing a new round of fundraising. The company says it purchased the tokens for €25.3 million (about $29.5 million), bringing its total holdings to 3,521 BTC.

According to a Capital B announcement released Monday, the purchase was financed following capital raises totaling roughly €30.1 million (about $35 million), including a private placement backed by investors Adam Back and TOBAM. Swissquote Bank Europe executed the trade, with Taurus providing custody.

Capital B’s latest treasury purchase

Capital B’s newly acquired 376 BTC represents a fresh expansion of its Bitcoin treasury, funded through the company’s recent funding activity. In its Monday filing and accompanying announcement, the company stated that the purchase price averaged €67,182 per BTC.

The execution and custody details add operational clarity for investors tracking corporate Bitcoin strategies. Swissquote Bank Europe carried out the acquisition, while Taurus is listed as the custody provider for the company’s Bitcoin holdings.

Where the company stands among corporate Bitcoin holders

Capital B also provided context on how the new purchase fits into its broader acquisition history. The company said it has spent a total of €309.4 million acquiring its Bitcoin portfolio, at an average cost of €87,878 per BTC.

Using rankings compiled by BitcoinTreasuries.net, the latest buying activity moved Capital B to 25th among publicly traded companies by Bitcoin holdings. The new total of 3,521 BTC places Capital B slightly ahead of Sweden-based H100 Group, which held 3,506 BTC after its earlier increase, though both remain behind Germany’s Bitcoin Group SE, which is reported to have 3,605 BTC.

Big buy since September 2025, but operational BTC is separated

The 376 BTC addition is Capital B’s largest purchase since September 2025, when the firm acquired 551 BTC for €54.7 million. That comparison matters for readers because it indicates a return to scale after a longer period without an equally large ticket size.

Capital B also distinguishes between treasury assets and operational holdings. The company says it holds an additional 61 BTC for operational purposes, which it keeps separate from its treasury reserve and excludes from its Bitcoin performance-related metrics. This separation is important when assessing reported results, since it clarifies that the treasury figures used for performance monitoring are not simply a blanket count of all BTC held.

Corporate accumulation continues even as some firms unwind

The Capital B purchase lands amid a mixed corporate landscape for Bitcoin treasuries. The article notes that some companies have moved to unwind Bitcoin holdings, including references to filings from firms such as K Wave Media and Sequans Communications. Against that backdrop, several other corporate players continue to accumulate.

Japan-based Metaplanet, for example, acquired 2,823 BTC during the second quarter for approximately $222 million, according to Cointelegraph reporting. Metaplanet’s holdings were stated at 43,000 BTC after that purchase, and BitcoinTreasuries.net rankings place the firm as the third-largest publicly traded corporate holder behind Strategy and Twenty One Capital.

Earlier activity also underscores the regional competition for BTC. In August, Sweden-based H100 Group more than tripled its Bitcoin exposure after an all-share deal involving Norwegian companies that held 2,455 BTC. That transaction increased H100’s treasury to 3,506 BTC, making it Europe’s second-largest publicly traded corporate holder at the time—until Capital B’s latest buy slightly closed the gap.

Meanwhile, Strategy—widely regarded as the largest corporate Bitcoin holder—resumed purchasing in August following a two-month pause. Cointelegraph previously reported that Strategy acquired 4,603 BTC for $370 million, lifting holdings to 845,050 BTC, acquired for a combined $63.3 billion. Together, these examples illustrate that corporate demand remains active even when individual companies choose to reduce exposure.

What to watch next

With Capital B scaling its treasury again after its September 2025 high, investors should watch whether the company sustains this pace of acquisitions and how it continues to structure funding rounds—particularly given the role of private placements and named backers in financing purchases. The next signal will likely come from whether Capital B schedules additional large buys or maintains a steadier, smaller accumulation strategy.
