Capital B just closed a €21.0 million private placement. That’s roughly $24.5 million, and the French Bitcoin treasury company didn’t do it quietly — Adam Back, one of Bitcoin’s most recognizable early figures, joined asset manager TOBAM as participants in the round.
The shares went out at €0.58 each, bundled with four share-subscription warrants per share, and sold without pre-emptive subscription rights. Pretty standard structure for a European private placement, but the warrant tail is where things get interesting. If every single warrant gets exercised, Capital B could pull in an additional €135.8 million — about $158 million — by issuing 144,876,280 ordinary shares. That’s not guaranteed money, obviously. It depends entirely on where the stock trades and whether warrant holders see enough upside to act.
The company also kept itself a specific trigger option. It can kick off an accelerated warrant exercise period if the volume-weighted average price of its shares clears 130% of the warrant exercise price across the prior 20 trading days. No details yet on whether that threshold looks close.
270 Bitcoin on the Shopping List
The immediate plan for the $24.5 million is straightforward: buy 270 Bitcoin. Capital B currently holds 3,139 BTC, so the purchase would push total holdings to 3,415 BTC. At current valuations, that stack sits at just under $249 million, which puts Capital B at 29th among publicly traded Bitcoin treasury companies.
For context, Bitcoin Group SE sits just ahead at 3,605 BTC, valued under $286 million. And then there’s Strategy — the benchmark everyone in this space gets measured against — sitting at 843,775 BTC worth nearly $67 billion. Capital B isn’t close to that number. Not even kind of close. But it’s clearly not trying to stay small either.
The gap between 29th place and the top of that leaderboard is enormous. Still, the direction of travel matters. Capital B is accumulating while some smaller treasury firms are actually going the other way, selling Bitcoin holdings rather than adding to them. That divergence is real, and it says something about where different companies think the market goes from here.
The €5 Billion Ceiling Shareholders Already Approved
Back in June, Capital B put a much bigger proposal to its board: authorize up to €5 billion — approximately $5.8 billion — in capital increases through the issuance of 125 billion shares at current nominal value, plus $116 billion in credit instruments. The vote came back with 162,486,459 votes in favor. That’s 99.34% approval. Basically unanimous.
That kind of shareholder backing is hard to dismiss. It doesn’t mean Capital B will raise €5 billion anytime soon — the market would need to cooperate, and warrant exercises would need to follow through — but the authorization is there. The legal runway exists. And the company now has a structure in place to move fast if conditions shift.
Worth noting: the €5 billion ceiling was proposed to the board, not yet fully executed. The June resolution cleared the path; it didn’t fill the tank. How much of that authorization actually gets tapped will depend on a lot of factors Capital B can’t fully control right now.
The Adam Back involvement is worth a sentence on its own. Back is the creator of Hashcash, the proof-of-work system that Satoshi Nakamoto cited directly in the Bitcoin whitepaper. He’s also CEO of Blockstream. His name showing up in a European Bitcoin treasury raise carries weight in this community — it’s not a random institutional check. TOBAM, the Paris-based asset manager, brings a different kind of credibility: traditional finance comfort with the structure.
Together, those two participants probably made the €0.58 share price easier to defend to other potential investors.
Capital B’s path forward isn’t simple. Warrant exercises are uncertain. The €5 billion capital framework is authorized but not funded. And the Bitcoin market itself can move hard in either direction fast — anyone holding 3,139 BTC knows that better than most.
But the August 28 announcement locks in the 270 BTC purchase, brings in $24.5 million in fresh capital, and keeps the warrant-driven upside alive at a potential $158 million. The 29th-ranked public Bitcoin treasury just made its next move.

This capital raise highlights increasing institutional interest in Bitcoin-related assets, reflecting a broader trend of traditional finance integrating more closely with the cryptocurrency market. The involvement of notable figures like Adam Back signals confidence in the sector's potential, while the structure of the placement with warrants may attract further investment as companies look for innovative ways to leverage Bitcoin's volatility. As the market matures, such fundraising efforts could pave the way for more sophisticated financial instruments tied to digital assets.
