French-Listed Capital B Expands Bitcoin Treasury With $29.4 Million Purchase
The firm increases its strategic holdings to 3,521 BTC, marking its largest acquisition in a year.
French-listed bitcoin treasury firm Capital B acquired 376 BTC on September 7, 2026, in a move that signals deepening institutional commitment to digital assets in Europe. The purchase, valued at €25.3 million (approximately $29.4 million), represents the company's most significant acquisition since September 2025.
According to reports from The Block and Cointelegraph, the acquisition brings Capital B's total strategic holdings to 3,521 BTC. The firm funded the expansion through recent capital raises, which included a private placement from Bitcoin SV creator Adam Back. Back invested €7.6 million into the company at a 15.4% premium, providing a portion of the liquidity necessary for the treasury expansion.
The Treasury Strategy
Capital B operates on the Euronext Growth Paris exchange, positioning itself as a specialized vehicle for bitcoin accumulation. Unlike traditional firms that may hold cryptocurrency as a secondary asset, Capital B functions as a dedicated treasury firm, aggressively utilizing capital markets to build a strategic reserve. By leveraging financing rounds and private placements, the company converts equity and debt into BTC, effectively turning its balance sheet into a digital asset vault.
Institutional Implications
This acquisition highlights a growing trend of European companies adopting a "MicroStrategy-style" playbook. By utilizing the public markets to fund the purchase of bitcoin, Capital B provides investors on the French stock market with a regulated proxy for bitcoin exposure without requiring them to manage private keys or navigate cryptocurrency exchanges directly. This model demonstrates how corporate treasury strategies are evolving to treat bitcoin as a primary reserve asset rather than a speculative investment.
Market Outlook
As Capital B continues to scale its holdings, market observers will be watching for further private placements and the potential for additional capital raises to fuel future buys. While the company has successfully integrated high-profile investors like Adam Back, the sustainability of this growth depends on its ability to maintain investor confidence in the Euronext Growth Paris market. It remains to be seen if other European listed firms will follow this aggressive accumulation model as institutional adoption accelerates across the continent.
