Capital B, the Paris-listed firm rebranded from The Blockchain Group in November 2024, says it has accumulated 3,140 Bitcoin over the past 12 months for what it calls Europe's first dedicated corporate Bitcoin treasury (company balance-sheet BTC holdings), worth roughly $200 million at an average cost basis (average purchase price) of about $104K per coin. The strategy began on November 5, 2024 and has included a 192 BTC purchase in May 2026 and a 1 BTC acquisition on August 3, 2026 for roughly €60,000, while the company continues to run legacy technology consulting operations focused on data intelligence, AI and decentralized technology. Capital B lists on Euronext Paris and recently expanded to Cboe Europe, and it counts Adam Back, the CEO of Blockstream, and Yves Choueifaty, founder of TOBAM, among its investors. The company plans a 10-for-1 reverse stock split (share consolidation) effective September 8, 2026, and its targets of 15,000 BTC by the end of 2027 and 210,000 BTC by 2033 would equal roughly 1% of Bitcoin's 21 million-coin maximum supply; for reference, Strategy holds well over 200,000 BTC, while the 2033 target would cost north of $20 billion at current prices and the 2027 goal implies roughly a fivefold increase in about 18 months.
