In a strong vote of confidence for corporate Bitcoin accumulation, Capital B, the French-listed Bitcoin treasury firm, has successfully raised $1.3 million (€1.1 million) from legendary cryptographer and Blockstream CEO Adam Back. Announced on May 4, 2026, the deal underscores a growing divide in the corporate world between firms liquidating their digital assets and those aggressively expanding their “Orange-pill” balance sheets.

Mechanics of  Back-Backed Raise

The capital injection was structured through the issuance of 10 million subscription warrants at a price of $0.13 each. These warrants grant Adam Back, the inventor of Hashcash and a seminal figure in the Bitcoin white paper, the right to purchase new shares at an exercise price of $0.98.

This transaction significantly deepens Back’s commitment to Capital B, bringing his total ownership to 39.5 million shares, or approximately 9.97% of the company on a fully diluted basis. Back’s recent activity suggests a focused effort to support the European Bitcoin ecosystem, as he similarly backed the UK-based Connecting Excellence Group (XCE) in late April.

Divergent Treasury Strategy

Capital B’s aggressive stance comes at a time when other public companies are flinching in the face of Bitcoin’s recent volatility. While firms like Nakamoto have shifted to active derivative hedging and Genius Group liquidated its holdings to settle debt, Capital B is using the current market conditions to accelerate its holdings.

The company currently sits as the 25th largest Bitcoin treasury globally, boasting a stash of 2,943 BTC, a portfolio valued at roughly $234 million in the current market. By opting for accumulation over liquidation, Capital B is positioning itself as a primary vehicle for European institutional investors seeking pure-play Bitcoin exposure on a regulated exchange.

Market Impact and Financial Outlook

Shareholders reacted positively to the news, sending Capital B’s stock (ALCB.PA) climbing more than 6.5% following the announcement. Despite the single-day rally, the company has faced a challenging 2026, with its stock price still down roughly 16% since the start of the year.

However, with the backing of one of Bitcoin’s most influential architects and a war chest of nearly 3,000 BTC, Capital B is betting that its long-term conviction will outweigh short-term market noise. As the race for corporate Bitcoin dominance continues, the partnership between Capital B and Adam Back ensures that the French firm remains a heavyweight contender in the global digital asset treasury rankings.
