Twenty One Capital Becomes 2nd Largest Public BTC Holder

• Twenty One Capital has ascended to become the second-largest publicly traded Bitcoin treasury, currently holding 43,514 BTC.
• The shift in rankings occurred after the mining firm MARA sold 15,133 BTC in March 2026, dropping it to third place.
• Strategy remains the undisputed leader in corporate Bitcoin accumulation with a total treasury of 762,099 BTC.

Changes in the Corporate Bitcoin Leaderboard

Led by Bitcoin advocate Jack Mallers, Twenty One Capital now holds a corporate treasury valued at over $2.9 billion based on current market prices. This move to the number two spot was facilitated by a substantial reduction in holdings by the mining giant MARA, which liquidated approximately $1.1 billion worth of Bitcoin throughout March 2026.

Behind these top three entities, the Japanese firm Metaplanet occupies the fourth position with 35,100 BTC. The rapid rise of Twenty One Capital highlights a growing trend of specialized treasury companies outperforming traditional mining operations in terms of long-term asset retention.

Listing and Market Performance

Twenty One Capital officially entered the public markets late last year following a successful business combination with Cantor Equity Partners, a special purpose acquisition company (SPAC). Now trading on the NYSE under the ticker XXI, the company has faced a challenging market environment. Since the start of the year, its shares have declined by more than 25%.

Strategic Models and Sustainability

The divergence in performance between miners and dedicated treasury companies has sparked debate among industry analysts. Tyler Rowe, an analyst at Bitcoin Treasuries, noted that Strategy has popularized a model where Bitcoin acts as "perpetual digital credit," using the asset as collateral for further acquisitions. This stands in stark contrast to the operational needs of miners.

• Mining companies may struggle to function as treasury entities without the complex capital market infrastructure built by figures like Michael Saylor.
• As access to cheap financing diminishes, firms trading at or below their net asset value (mNAV) may be forced to liquidate holdings to service debt.

Market Climate and Future Outlook

The broader cryptocurrency market has been under pressure since a bear market began in October 2025. This environment has led to what some observers call a "capitulation" phase for mining and treasury firms with weaker balance sheets. Experts from HashKey Capital suggest that companies viewing Bitcoin as a speculative bet are likely to fail, while those with a disciplined, long-term treasury strategy are better positioned to survive multiple market cycles.
