Bitcoin (BTC) investors looking for a regulated on-ramp just got a new vehicle. Bitcoin-native firm Twenty One Capital, co-founded by Jack Mallers, has officially launched on the NYSE under the ticker “XXI.” Equipped with a multi-billion-dollar BTC treasury and strong institutional backing, the company aims to become a major bridge between traditional finance and digital assets, offering public investors exposure to Bitcoin via a corporate entity rather than directly through exchanges or wallets.
At the time of its launch, Twenty One Capital is said to hold 43,514 BTC, worth around USD 4 billion – among the largest corporate Bitcoin treasuries that are publicly traded today. Institutional heft comes from the firm’s backers, among which are Tether, the world’s largest stablecoin issuer, Bitfinex, and SoftBank Group.
Whereas other firms might be content as crypto treasury outfits, Twenty One aspires to something very different: an all-rounded BTC-aligned enterprise architecture, contemplating bitcoin-native financial products and services, and perhaps even capital market tools denominated in BTC.
This offering gives investors an alternative route to BTC exposure via a regulated, public entity. To many, this may seem less risky than holding crypto directly because one would not have self-custody, private keys, or exchange risks while still offering upside tied to BTC’s value and company growth.

The timing of Twenty One is notable: with institutions increasingly showing interest in BTC its public listing comes at a moment when traditional investors are considering how to fit crypto exposure into regulated portfolios. Major industry players like Tether, SoftBank, and Bitfinex also participated in the round, a signal that some of the biggest names in crypto and finance are confident in it.
Besides accumulation, the ambition to build Bitcoin-native products suggests a vision toward integrating BTC into the greater financial system via services, instruments, and infrastructure that may accelerate mainstream crypto adoption.
