Twenty One Capital
NYSE: XXITwenty One didn't slowly evolve into a bitcoin company the way Strategy did — it was built as one from day one, by some of bitcoin's biggest institutional names.

Who they are
Twenty One Capital launched in late 2025 through a SPAC merger, entering the public markets already holding more than 43,000 bitcoin — making it the third-largest corporate bitcoin treasury in the world on day one. Where Strategy built its position gradually over years, Twenty One was purpose-built from the start: majority-owned by Tether (the stablecoin issuer), with a significant stake from Bitfinex and, initially, SoftBank Group.
CEO Jack Mallers is a well-known bitcoin figure in his own right — founder of Strike, a bitcoin-based payments app, and an advisor during El Salvador’s adoption of bitcoin as legal tender.
What they actually do
Hold and grow a large bitcoin treasury. Like Strategy, Twenty One measures itself on “Bitcoin Per Share” and “Bitcoin Return Rate” — metrics designed to show shareholders that ownership per share is growing, not just that the company holds a lot of coins.
Consolidate ownership under Tether. In May 2026, Tether bought out SoftBank’s entire stake, removing SoftBank’s board seats and leaving Tether as the uncontested majority shareholder — a sign of how tightly this company is now tied to Tether’s own strategic ambitions.
Pursue a much bigger structural transformation. Tether has proposed merging Twenty One with Strike (Mallers’s payments company) and Elektron Energy (a large-scale bitcoin mining operator), which would combine treasury holdings, mining, financial services, and lending under a single public company — a far more ambitious scope than a typical treasury vehicle.
How they make money
Currently, almost entirely bitcoin price appreciation on its treasury holdings. If the proposed three-way merger with Strike and Elektron closes, the company would add mining revenue and financial-services fees on top.
Where it sits in the value chain
The bigger trend it’s riding
Twenty One represents a second generation of the bitcoin treasury model: rather than a public company gradually converting itself (Strategy’s path), it’s an entity engineered from inception by crypto-native institutions — Tether and Bitfinex — to be a pure bitcoin vehicle from day one, with ambitions to expand well beyond treasury into a full-stack bitcoin business.
What to watch (not what to do)
What to watch (not what to do)
- Whether the three-way merger actually closes. As of the proposal, no terms, timeline, or governance structure had been disclosed. This is a stated intention, not a signed transaction.
- The gap between valuation and execution. XXI's stock has traded well below its post-listing highs, with critics noting the company has shown little operational activity beyond holding bitcoin so far.
- Tether concentration. With Tether now the dominant shareholder and driving strategic direction, Twenty One's fortunes are closely tied to decisions made at a company that isn't itself publicly traded or as transparent as a typical public parent.
