Capital B's trading volume more than doubled within two hours of its debut on Cboe Europe on August 5, quickly surpassing activity on its original Euronext Growth Paris listing under ticker ALCPB. The secondary listing on Europe's largest pan-European stock exchange provided European institutional investors with improved liquidity access to the Bitcoin treasury company.
Capital B rebranded from The Blockchain Group in late 2024 and targets accumulating 1% of Bitcoin's total supply, approximately 210,000 BTC. The company currently holds between 2,834 and 3,140 BTC, funded partly by a €15.2 million private placement completed in May 2026.
