According to this press announcement, Twenty One Capital will debut with an estimated 43,500 BTC, a reserve valued near $4 billion at recent market levels. This immediately places it among the top corporate Bitcoin treasuries globally. Unlike companies that hold Bitcoin as a secondary reserve, Twenty One is specifically engineered around a Bitcoin-native model. The firm intends to report “Bitcoin-per-share,” providing investors a transparent look at how much BTC each equity unit represents. It also pledges full, on-chain proof-of-reserves, positioning itself as a high-transparency asset custodian at launch.
