French Bitcoin-treasury firm Capital B has expanded its market presence and capital reserves to support its strategy of accumulating Bitcoin. In early August 2026, the company debuted on Cboe Europe, a move intended to deepen liquidity and provide institutional investors with broader access to its stock, which acts as a leveraged proxy for Bitcoin exposure. Following this debut, the company successfully raised €21 million through a private placement to accelerate its treasury expansion. This funding round, which included backing from Adam Back and TOBAM, is intended to facilitate the purchase of additional Bitcoin, furthering the firm’s goal of using capital raises to build a primary reserve of the cryptocurrency.
