Capital B’s Funding Push
Capital B has increasingly used equity financing to expand its Bitcoin treasury. Earlier in September, the company raised €7.6 million from Blockstream co-founder Adam Back to support its Bitcoin strategy. Back has also participated in previous Capital B financing rounds.
In June, shareholders approved additional financing capacity intended to support the company’s Bitcoin treasury strategy. The company’s approach is focused on increasing the amount of Bitcoin held per fully diluted share over time. Capital B uses BTC Yield as one of its key indicators to track this metric.
The company, however, said BTC Yield should not be treated as a traditional investment return, profitability measure or financial performance indicator.

Capital B ranks among the 25 largest publicly listed Bitcoin holders, based on BitcoinTreasuries’ data. Strategy ranks first with 846,000 BTC, followed by Twenty One Capital with 43,514 BTC, and Japan’s Metaplanet with 43,000 BTC. Capital B currently holds the 25th position with 3,538 BTC. Its Bitcoin treasury has grown rapidly from 40 BTC in December 2024 to more than 3,500 BTC today, with major purchases including 624 BTC in June 2025, 551 BTC in September 2025 and 376 BTC earlier in September 2026. The company continues to use equity financing as part of its strategy to expand its Bitcoin reserves.
