43,500 BTC and self-custody

It is understood that Twenty One currently holds approximately 43,500 BTC, with a market value of approximately US$4 billion (becoming the second largest corporate Bitcoin holder after Strategy). As part of the settlement process, the team has transferred 43,122 BTC of this amount from the third-party account to the company’s self-managed wallet. In the future, through the reserve certificate website, shareholders can instantly verify assets on the chain.

CEO Jack Mallers has long advocated for Bitcoin sovereignty. He said on the eve of listing:

Bitcoin is an honest currency, and we only do one thing: continue to increase the number of coins held per share.

Unlike Strategy and mining companies that still have software or mining revenue, XXI currently has no other operating businesses and focuses solely on currency holdings. Analysts judge that 21 Capital will develop a series of Bitcoin-native financial products and tools in the future, such as providing Bitcoin spot mortgage services for institutional customers, with the goal of filling the gap between crypto assets and current traditional financial services.

Tether holds the largest shares

Twenty One Capital’s shareholder list. Tether, the world’s largest stablecoin issuer, is its major shareholder, holding up to 51.7% of the voting rights. Today (3) Paolo Ardoino, co-founder of Tether, issued a message stating that the Bitcoin purchased by SoftBank has arrived.

Other significant investors include Japan’s SoftBank Group, cryptocurrency exchange Bitfinex and Wall Street investment bank Cantor Fitzgerald.

The company is co-led by Strike founder Jack Mallers and Brandon Lutnick, son of former Cantor Fitzgerald chairman Howard Lutnick.
