Formerly known as The Blockchain Group, Capital B adopted a "corporate Bitcoin standard" in November 2024 and formally rebranded under its current name in July 2025, marking a deliberate and recent pivot to a Bitcoin treasury strategy. Understanding that timeline is essential context for evaluating the company's position today.

The acquisition was funded through capital raises completed in late August and early September 2026. The company trades on Euronext Growth Paris under the ticker ALCPB and on US over-the-counter markets as CPTLF. It paid an average of about €67,182 (roughly $77,900) per bitcoin for this tranche. Capital B's overall average acquisition cost across its full position stands at €87,878 per BTC, equivalent to approximately $102,058. Because the current market price of bitcoin sits well below that aggregate cost basis, the company carries an unrealized loss of approximately $79.45 million across its full position.

In addition to its 3,521 BTC strategic reserve, Capital B holds a further 61 BTC separately for operational purposes, bringing total bitcoin on the balance sheet to 3,582 BTC.

How the Purchase Was Funded

Capital B raised capital through two equity placements and an ongoing at-the-market facility before executing the buy.

On August 28, the company raised €21.01 million through a private placement of 36.22 million shares priced at €0.58 each, a 6.45 percent discount to the prior close. Investors in that placement received four warrants per share, exercisable over five years across strike price tiers of €0.75, €0.98, and €1.27. Participants included Blockstream CEO Adam Back and French asset manager TOBAM.

On September 2, Back separately subscribed for an additional 13.18 million shares at the same €0.58 price, committing another €7.64 million and raising his direct stake in Capital B from 14.82 percent to 17.64 percent of ordinary capital. TOBAM contributed a further €1.44 million through its ongoing at-the-market facility. Total net proceeds came to roughly €28.7 million after fees.

Back is one of the most credentialed figures in Bitcoin's technical history. His Hashcash proof-of-work algorithm is cited directly in Satoshi Nakamoto's original Bitcoin whitepaper, and his affiliated entity Blockstream Capital Partners holds 18.77 percent of Capital B's ordinary capital. If all warrants from the September placement are eventually exercised, his personal stake could reach 27.8 percent, though that outcome depends on the share price reaching each applicable strike level.

Capital B did not provide an executive statement specific to this purchase. Back has previously described Capital B's model as "aligned with Blockstream's long-term vision of Bitcoin as a reserve asset."

Position in Europe and Globally

The purchase narrows the gap between Capital B and Bitcoin Group SE, the German-listed firm that currently leads European corporate bitcoin holders with approximately 3,605 BTC. Capital B needs just 84 more bitcoin to claim the top spot on the continent.

Globally, the company ranks 25th among 179 listed companies across 30 countries that hold bitcoin, according to tracking data from Bitcoin Treasuries. Those 179 firms collectively hold about 1.287 million BTC, roughly 6.1 percent of the total bitcoin supply that will ever exist, valued at approximately $102 billion. Strategy, formerly known as MicroStrategy, dominates that group with 845,050 BTC, accounting for about 65.7 percent of all corporate bitcoin holdings. Twenty One Capital ranks second among corporate holders globally with 43,514 BTC, illustrating the considerable scale gap between Strategy and the rest of the field.

Capital B reported a year-to-date bitcoin yield of 2.17 percent, a metric that measures growth in BTC holdings per diluted share rather than price appreciation. For context, Strategy has reported a YTD BTC yield of 13.3 percent, which may reflect the advantage of earlier and larger-scale accumulation at lower average prices.

The Unrealized Loss: A Cautionary Signal for Emerging-Market Imitators

Capital B's total cost basis across its 3,521 BTC reserve stands at approximately €309.4 million ($359.45 million). At current market prices, those holdings are worth roughly $280 million, leaving an unrealized loss of approximately $79.45 million. Bitcoin would need to climb back above approximately $102,000 per coin for the company to break even on its aggregate position.

For investors evaluating Capital B as a vehicle or as a model to replicate, the company's equity valuation adds another layer of complexity. Capital B's stock trades at a meaningful discount to net asset value: 0.82 times NAV on a diluted basis and 0.45 times NAV on a basic basis. Firms in emerging markets considering similar strategies should account for equity valuation dynamics, not only treasury performance, before treating the model as straightforwardly replicable.

The gap matters beyond Capital B's own balance sheet. The company describes itself as Europe's first Bitcoin Treasury Company and has set targets of 15,000 BTC by end-2027 and 250,000 BTC by 2033. Its model is being watched and replicated across emerging markets. Africa Bitcoin Corporation, a Johannesburg Stock Exchange-listed firm formerly known as Altvest Capital, rebranded in 2025 along similar lines and is targeting a $210 million bitcoin allocation. CEO Warren Wheatley has framed the structure as a way to give African pension funds and retirement annuity investors regulated indirect exposure to bitcoin through equity. "This creates a new gateway for institutional investors in Africa," Wheatley has said.

The regional backdrop strengthens the case for that framing. Sub-Saharan Africa crypto adoption grew 52 percent between July 2024 and June 2025, according to Chainalysis, and Nigeria ranks sixth globally in the Chainalysis 2025 Global Crypto Adoption Index.

In India, IT training firm Jetking has made a comparable move on a much smaller scale, targeting a 210 BTC reserve and positioning itself as the country's first publicly listed bitcoin treasury company. The contrast with Capital B's 3,521 BTC position is stark, reflecting both capital constraints and regulatory caution in South Asia relative to Europe. Pakistan has moved at the sovereign level, establishing a national bitcoin reserve with MicroStrategy founder Michael Saylor, whose company has since rebranded as Strategy, serving as an advisor. That announcement drew considerable attention across the region; reports noted that prominent voices in India's bitcoin community expressed surprise at Pakistan's move, underscoring the growing competitive dimension of sovereign and corporate bitcoin accumulation in South Asia.

For any firm in those markets considering a similar accumulation strategy, Capital B's current position illustrates the balance sheet risk that comes with buying bitcoin at scale during periods of price contraction. Companies with shallower capital reserves have considerably less room to absorb an unrealized loss of that size.

What Comes Next

Capital B has established Capital B Treasury Limited in Abu Dhabi, describing the subsidiary in an official statement as an entity that "will play a central role in supporting the Group's international expansion, particularly in the development of global institutional partnerships to accelerate the emergence of digital capital markets, at the intersection of Bitcoin and traditional finance." The MENA region also provides a corridor to institutional capital from sovereign wealth funds in the UAE, which have been expanding their own bitcoin holdings, making Abu Dhabi a strategically significant base for Capital B's international ambitions.

Bitcoin was trading at approximately $77,934 as of September 3, within an analyst consensus range of $70,000 to $90,000 for the year. Whether prices recover toward the company's $102,000 break-even level will be the defining near-term question for its treasury strategy and for the growing number of companies globally that are watching its model.
