Jack Mallers’ Twenty One Capital (XXI) secured new funding.

Jack Mallers’ Bitcoin-focused financial services company Twenty One Capital (NYSE: XXI) has reportedly secured new funding, adding to the capital base behind one of the largest public corporate Bitcoin treasuries. The firm, co‑founded by Mallers alongside major backers including Tether and formerly SoftBank, already holds more than 43,000 BTC on its balance sheet, making it the second‑largest public company Bitcoin holder behind MicroStrategy. Any fresh capital raises further reinforce its role as a listed vehicle for large-scale Bitcoin exposure. Twenty One was created through a business combination with Cantor Equity Partners, with sponsors contributing over $1.2 billion in Bitcoin and arranging roughly $585 million in additional committed capital via subscription agreements at launch, alongside several hundred million dollars in associated debt financing. The company positions itself as a Bitcoin-native financial services platform, focusing on treasury management, credit, and lending products that use Bitcoin as core collateral. Earlier, Tether acquired SoftBank’s entire stake in the firm, consolidating control and effectively turning Twenty One into a key public operating arm for Tether’s Bitcoin strategy. In this context, new funding is material because it can expand Twenty One’s capacity to scale its Bitcoin-backed lending, balance sheet structure, and broader institutional market presence around Bitcoin.
