TechNewsReel Newsroom · September 14, 2026

Capital B has further expanded its digital asset reserves, purchasing an additional 4 BTC to bring its total corporate treasury to 3,525 BTC. The move reinforces the company's position as a primary institutional holder of Bitcoin within the European public markets.

The most recent acquisition cost approximately 0.27 million euros, according to ABC Bourse. This purchase was funded through the proceeds of previously described capital operations. The addition follows a larger prior expansion in which the company acquired 376 BTC for $29.4 million, which had previously brought its holdings to 3,521 BTC.

Strategic Infrastructure

Listed on Euronext Growth Paris, Capital B operates as a Bitcoin treasury company that aggressively scales its reserves through strategic investments and capital raises. To manage these high-value assets, the firm utilizes Swissquote Bank Europe for trade execution and Taurus for secure custody. The company's institutional credibility is further underscored by its shareholder base, which includes Bitcoin pioneer Adam Back, who holds 17.62% of ordinary shares and 14.66% on a diluted basis.

The European Treasury Model

This strategy mirrors the "MicroStrategy" model, where a public company leverages capital markets to acquire Bitcoin as its primary reserve asset. By utilizing equity markets to fund BTC purchases, Capital B is signaling a shift in how European public companies may approach balance sheet management. As one of the largest public Bitcoin treasury companies in Europe, its actions provide a blueprint for other institutional players looking to integrate digital assets into a corporate structure.

Market Implications

The continued accumulation by Capital B highlights the growing institutional adoption of Bitcoin as a treasury reserve in the EU. While the most recent purchase was modest in size compared to previous rounds, the consistency of the acquisitions demonstrates a long-term commitment to the asset. Investors will likely watch for further capital raises or ATM agreements that could facilitate larger-scale purchases as the company continues to scale its holdings.
