Capital B Adam Back Warrant Subscription 2026 Pulls In $1.28M

The Capital B Adam Back warrant subscription 2026 deal pulled in $1.28 million for the French Bitcoin treasury firm in May. Back, the CEO of Blockstream and one of the original cypherpunks, purchased 10 million subscription warrants at $0.13 each, doubling down on a company he has backed since it first built out its BTC accumulation strategy. The deal keeps Capital B among the handful of European listed firms still raising capital during Bitcoin’s current correction cycle, rather than selling into it.

Inside the Capital B Adam Back Warrant Subscription 2026 Deal

The mechanics are simple enough. Each of the 10 million warrants Back purchased gives him the right to buy one new share of Capital B stock at an exercise price of $0.98. That price corresponds to the company’s market net asset value ratio of 1.1 per share, meaning Back is buying in at a slight premium to NAV, not at a discount. Capital B disclosed the transaction in a Monday announcement, with the Capital B Adam Back warrant subscription 2026 confirming that the full EUR 1.1 million raise was subscribed entirely by Back.

Back is not a new face at Capital B. He was already one of the company’s largest strategic investors before this transaction. After the warrant purchase, he now holds over 39.5 million shares, which works out to roughly 9.97% of the company on a fully diluted basis. That is close to a 10% stake, a meaningful anchor position in any small-cap company.

Outside of crypto circles, Back is probably best known as the inventor of Hashcash, the proof-of-work algorithm that Satoshi Nakamoto cited directly in the Bitcoin white paper. Inside crypto, he is recognized as one of the earliest cypherpunks and a long-standing Bitcoin maximalist. His continued investment in Capital B is not a side bet, it lines up precisely with his public statements about corporate Bitcoin adoption.

The new capital will be used to accelerate its Bitcoin treasury strategy.

How Large Is Capital B’s Bitcoin Treasury?

As of early May 2026, Capital B holds 2,943 BTC, currently valued at roughly $234 million. That puts it at number 25 on the global ranking of corporate Bitcoin holders, according to Capital B bitcoin treasury 2943 BTC holdings data from Bitcointreasuries.net. It is a smaller stack than the top-tier names, but meaningful in the European listed company context.

Capital B trades on the Paris stock exchange under the ticker ALCB.PA. The stock jumped more than 6.5% on Monday after the announcement, which shareholders appear to have read as a positive vote of confidence. That reaction makes sense, having a figure with Back’s reputation double down at close to a 10% diluted stake sends a clear signal about direction.

That said, the year-to-date picture is less cheerful. Capital B shares are still down more than 16% since January 1, 2026, according to Yahoo! Finance data. That mirrors what most Bitcoin treasury company stocks have done during the same period as Bitcoin worked through its own correction. The warrant subscription does not erase that underperformance, but it does give the company fresh capital to keep accumulating BTC rather than selling to cover operating costs.

Europe’s Bitcoin Treasury Firms Are Raising Capital. Who Else?

Capital B was not the only European Bitcoin treasury company to raise money recently. UK-based Connecting Excellence Group, which trades under the ticker XCE, closed a $794,000 capital raise on April 23, 2026, and that round was also backed by Adam Back. The Connecting Excellence Group XCE Adam Back 794000 capital raise filing shows Back is actively placing capital across multiple European Bitcoin treasury vehicles, not just Capital B.

Together, Capital B and XCE were the only two Bitcoin treasury companies in Europe to raise capital over the past month. That is a short list. European Bitcoin treasury firms are still much fewer in number than their US counterparts, and the regulatory and listing environment is different. Back appears to be building a deliberate exposure across both the French and UK markets.

The broader picture outside Europe is more mixed. Some Bitcoin treasury firms are raising new capital, as Capital B is doing. Others are taking a different route, managing balance sheet risk through derivatives, selling Bitcoin holdings to pay down debt, or cutting exposure entirely. The strategy divergence is real, and it reflects the fact that there is no single playbook for running a corporate Bitcoin treasury through a market downturn.

What Are Other Bitcoin Treasury Companies Doing With Risk?

Not every Bitcoin treasury company is in accumulation mode right now. On April 24, Nasdaq-listed Nakamoto announced an actively managed Bitcoin derivatives program. The program targets recurring income from volatility while also hedging part of its corporate BTC holdings against further downside. Nakamoto ranks as the 20th largest Bitcoin treasury firm globally, and it was the largest company to publicly disclose selling part of its holdings earlier this year.

Nakamoto reported the sale of 284 Bitcoin, worth roughly $20 million at the time, in a March 30 filing with the US Securities and Exchange Commission. That is a meaningful drawdown of a corporate treasury and a clear sign that not every firm is in a position to hold through volatility without consequences.

The situation at Genius Group was even more dramatic. In February, Genius Group said it liquidated its entire treasury position of 84 BTC, worth about $5.7 million, to pay down an $8.5 million debt obligation, according to a separate SEC filing. Selling your entire Bitcoin treasury to service debt is not a treasury strategy. That is survival mode. It shows the gap between companies like Capital B, which can raise fresh capital from credible backers like Back, and those that cannot.

Capital B’s warrant deal with Back puts it clearly in the first camp. The company is not selling BTC. It is raising equity capital to buy more. Back, for his part, is not diversifying away from his Bitcoin thesis, he is concentrating it, across multiple balance sheets, in multiple jurisdictions. Whether that conviction pays off depends on where Bitcoin trades when those warrants eventually get exercised at $0.98 per share.
