On December 9, 2025, Twenty One Capital began trading on the NYSE under the ticker “XXI” as the third largest Bitcoin holder (~$4B). [RELEASE]
Everyone sees Twenty One Capital as another MicroStrategy clone. The market saw it too: XXI dropped 25% on its NYSE debut to $11, trading at 0.80x NAV.
But while investors fixate on the Bitcoin treasury playbook, they're missing what Tether, Cantor Fitzgerald, and SoftBank actually built: a closed-loop monetary infrastructure disguised as a public company.
This isn't about holding Bitcoin. It's about controlling the rails.
Shares opened and immediately fell 20-24% below their underlying value. Investors were willing to pay $3.2B for a $4B asset. And XXI traded below its NAV (0.80x to 0.90x mNAV) because the market saw it as a costly way to hold Bitcoin at a time when cheap spot ETFs already exist.
But the market is pricing it wrong.
Twenty One Capital (the third largest Bitcoin corporate holder) isn’t just a treasury company. It’s a closed-loop monetary system disguised as one.
The capital structure tells the deeper story. XXI secured $585M in additional closing capital, including $385M in convertible senior secured notes and a $200M common equity PIPE.
Who owns it: Led by Jack Mallers, a Bitcoin evangelist, the firm is backed by a powerful triumvirate: Tether (which issues the world’s most popular stablecoin), Cantor Fitzgerald (a major Wall Street firm), and SoftBank Group (a Japanese technology conglomerate with hundreds of billions in assets).
