Are Bitcoin treasuries bigger than we think?

Institutional bitcoin holdings have long been defined by headline names like MicroStrategy and Tesla. But a new entrant has quietly emerged with one of the largest stashes of BTC on record. According to Cointelegraph (

), Twenty One Capital now holds over 43,500 BTC, making it one of the largest known corporate treasuries in the world.

Backed by Cantor Fitzgerald and led by Strike founder Jack Mallers, the firm’s previously undisclosed holdings are now coming into focus. At today’s prices, its bitcoin holdings are worth over $5.1 billion, more than several public miners and fintech companies combined.

Initial estimates pegged Twenty One’s holdings at around 38,000 BTC. But a new tranche of 5,800 BTC was recently confirmed, part of a capital infusion from Tether tied to Twenty One’s upcoming merger with Cantor Equity Partners. That brings its total stash to 43,514 BTC, as confirmed in public filings and reporting from

. This positions the firm ahead of Marathon Digital (MARA), which holds around 50,000 BTC, and behind only MicroStrategy (with over 600,000 BTC under management via Strategy). Notably, Twenty One acquired its position in less than a year, an aggressive accumulation pace not seen since the early 2021 bull cycle.

Twenty One’s launch was seeded with approximately $685 million in equity, including backing from Bitfinex, SoftBank, and Tether. As highlighted in

, the fund raised capital through both crypto-native and traditional finance channels.

Jack Mallers, the outspoken Bitcoin advocate and founder of Strike, serves as CEO. He’s long criticized centralized monetary policy and has advocated for companies to move their treasuries into bitcoin as a long-term inflation hedge. In this case, his strategy has translated into one of the fastest-growing treasuries in crypto.

While the sheer BTC amount is eye-catching, what’s more notable is how Twenty One is structuring its exposure. Unlike many other treasuries, the firm has avoided leverage and debt financing. As noted in

, its purchases have been funded largely through equity issuance and stablecoin transfers, reducing risk while maximizing flexibility.

That financial structure could make it more resilient during downturns. Many previous treasury strategies faltered when bitcoin's price dropped or interest rates rose, especially those exposed to margin calls or bond drawdowns.

Twenty One is also exploring new applications of its BTC reserves. According to

, the company is considering a lending program where users or institutions can borrow USD using bitcoin as collateral. This move mirrors models developed by firms like BlockFi and Ledn, but with larger scale and public visibility.

Another innovation is the introduction of a Bitcoin-Per-Share (BPS) metric, designed to communicate shareholder value relative to BTC holdings. This mirrors gold ETFs, where NAV is tied directly to ounces held. With BPS, investors can see in real time how much bitcoin backs each unit of equity in the firm. This level of transparency may attract institutional buyers who prefer auditable, asset-backed investments over vague crypto strategies. As

notes, the firm’s dashboard will include both on-chain verification and real-time balance sheet disclosures.

The rise of Twenty One raises a larger question: how many corporate bitcoin treasuries are bigger than we think?

According to

, public company disclosures often lag behind real holdings. While MicroStrategy is transparent, many firms only reveal BTC exposure quarterly, or not at all. With new SPACs, private vehicles, and hybrid trusts entering the space, the true number may be much higher.

Analysts at

have noted that corporate BTC strategies might be cyclical or short-lived, based on pricing momentum. But others believe this is a structural shift, not a trend. Mallers himself has forecast that bitcoin’s scarcity will push institutional demand to record highs by 2026.

As treasury-backed tokens begin to surface across Ethereum, Avalanche, or Arbitrum, liquidity and routing become a key challenge.

allows users and traders to move assets between chains where treasury-backed or synthetic BTC products are deployed. With

, analysts and users alike can track wallet flows tied to corporate treasury addresses (often publicly known) and detect inflows or outflows to lending pools, OTC desks, or on-chain vaults.

For those unfamiliar with how treasury data flows across chains,

offers a practical introduction. It includes guidance on reading wallet clusters, interpreting treasury events, and managing exposure to BTC-backed tokens. Meanwhile,

goes deeper, covering arbitrage between treasuries, collateral yield strategies, and pricing models based on BPS or net flow indicators.

One major milestone will come later this year. Twenty One is finalizing its merger with Cantor Equity Partners, which will make the firm publicly tradable. According to

, the SPAC deal could close by Q4 2025.

That would bring Twenty One into direct comparison with MicroStrategy, Galaxy, and Metaplanet as publicly listed “Bitcoin proxy plays.” It could also broaden investor access, especially among funds unable to hold spot crypto directly. More broadly, if other firms follow suit, BTC per share could become a new standard in corporate valuation, especially in macro environments where fiat-based strategies continue to underperform.

The rise of corporate treasuries like Twenty One is reshaping the narrative around Bitcoin’s institutional role. No longer is BTC just a speculative asset, it’s becoming a core balance sheet allocation for firms seeking inflation protection, cross-border liquidity, and programmable collateral. We’ve already seen governments, miners, and public companies adopt BTC as treasury insurance. Now, a new wave of firms is scaling that strategy, with better tools, cleaner disclosures, and growing capital flows.
