Capital B Secures $24.5M in Bitcoin Treasury Funding Led by Blockstream’s Adam Back
French Bitcoin treasury firm Capital B raised €21.0 million through private placement, with potential for $158 million additional capital via warrant exercises. The raise includes participation from Bitcoin veteran Adam Back and asset manager TOBAM.
French Bitcoin treasury company Capital B announced €21.0 million ($24.5 million) in fresh capital raised through a private share placement on August 28, 2026. The fundraise attracted participation from prominent figures including Blockstream CEO and Bitcoin advocate Adam Back, as well as asset management firm TOBAM. The funding marks a significant capital commitment to expanding the company’s digital asset reserves amid a period of market transition.
Capital B’s Multi-Layered Funding Structure
The private placement was structured at €0.58 per share, with each share purchase bundled with four share-subscription warrants—financial instruments that could unlock substantial additional capital. Should shareholders exercise all issued warrants in full, Capital B stands to receive an additional €135.8 million ($158 million) through the issuance of 144,876,280 ordinary shares. This two-stage capital framework gives the company flexibility while providing existing investors with meaningful upside participation.
To incentivize warrant exercise, Capital B retains the right to trigger an accelerated exercise period if the company’s share price climbs to 130% of the warrant exercise price when measured across a 20-day volume-weighted average. This mechanism could accelerate capital deployment if market conditions prove favorable.
Expanding Bitcoin Holdings in a Competitive Landscape
Capital B intends to deploy the immediate $24.5 million capital infusion toward acquiring 270 Bitcoin, which would expand the company’s total holdings to 3,415 BTC. This expansion positions Capital B among the global leaders in corporate Bitcoin accumulation, though substantial competition exists within the emerging Bitcoin treasury space.
According to current CoinMarketCap data, Capital B ranks as the 29th largest publicly traded Bitcoin treasury company. While this represents a meaningful position, larger competitors already dominate the sector. Bitcoin Group SE maintains 3,605 BTC worth approximately $286 million, while the sector leader, Strategy, commands a substantially larger position with 843,775 BTC valued near $67 billion.
From Board Approval to Market Positioning
Capital B’s current fundraise follows an ambitious proposal approved by shareholders in June 2026, when the board sought authorization for up to €5 billion ($5.8 billion) in additional capital through 125 billion shares and $116 billion in credit instruments. Shareholders endorsed the framework with overwhelming support, with 99.34% voting in favor—a strong mandate for aggressive capital deployment.
The participation of Adam Back, whose technical expertise and public advocacy have shaped Bitcoin’s development trajectory, signals confidence in Capital B’s accumulation strategy even amid market uncertainty. His support, combined with TOBAM’s institutional backing, suggests that sophisticated investors view the timing and structure favorably.
For Bitcoin and the broader crypto ecosystem, Capital B’s expansion illustrates how publicly traded companies continue channeling institutional capital into Bitcoin treasuries, potentially supporting long-term price discovery and accelerating corporate acceptance of Bitcoin as a strategic asset.
