How to Buy Twenty One (XXI) Bitcoin Treasury Company

Twenty One (NASDAQ: XXI, formerly CEP through SPAC merger) is a US-based company, founded by Jack Mallers, that has rapidly become one of the largest public Bitcoin treasury firms in the world. After rebranding and assembling key partners like Tether, Bitfinex, and SoftBank, the company’s mission is to maximize Bitcoin-per-share (BPS) for investors and pioneer a new generation of Bitcoin-native financial solutions.

Twenty One is a pure-play Bitcoin treasury company designed for high Bitcoin exposure per share. The firm is committed to boosting shareholder value by growing its BTC holdings through capital raises and strategic partnerships. By September 2025, the company holds over 43,500 BTC (acquired for an average cost of $87,280 each), making it the third-largest corporate BTC holder after Strategy and Marathon Digital.

Innovative treasury management practices include:

  • Collaborations with Tether and SoftBank enabling access to large pools of capital.

  • Offering new performance metrics, like Bitcoin Per Share (BPS) and Bitcoin Return Rate (BRR), for highly transparent, real-time shareholder reporting.

  • Full on-chain proof-of-reserves, allowing public verification of BTC holdings.

  • All capital raises are aimed at increasing BTC per share for investors, making XXI a leveraged Bitcoin investment.
