Tether Tightens Control Over Twenty One Capital After Buying Out SoftBank Stake

Stablecoin giant Tether has officially acquired SoftBank’s stake in Twenty One Capital, further consolidating its control over one of the largest Bitcoin treasury firms in the world. The announcement pushed shares of Twenty One Capital (NYSE: XXI) higher as investors reacted positively to Tether deepening its commitment to the Bitcoin-focused company. 

Tether Takes Full Control of Twenty One Capital

The transaction removes SoftBank Group from Twenty One Capital’s ownership structure and board governance. Following the deal, SoftBank representatives officially stepped down from the company’s board in accordance with shareholder agreements. Financial terms of the acquisition were not publicly disclosed, but the move significantly strengthens Tether’s influence over the company’s long-term strategy.

Twenty One Capital was originally launched in 2025 through a SPAC merger backed by:

• Tether
• Bitfinex
• SoftBank
• Cantor Fitzgerald affiliates.

The company was designed as a Bitcoin-native public corporation focused on accumulating BTC and building financial services around Bitcoin infrastructure.

Twenty One Capital Is Becoming a Bitcoin Conglomerate

Unlike companies that simply hold Bitcoin on their balance sheet, Twenty One Capital has positioned itself as a broader operating company built entirely around the Bitcoin economy.

According to company statements, its long-term vision includes:

• Bitcoin treasury operations
• Mining infrastructure
• Lending
• Financial services
• Capital markets products
• Strategic acquisitions.

The company currently holds more than 43,500 BTC, making it one of the largest corporate Bitcoin holders globally. CEO Jack Mallers has repeatedly described the firm as a “Bitcoin-native public company” rather than a traditional treasury vehicle.

Tether’s Bitcoin Strategy Continues Expanding

The acquisition also highlights how aggressively Tether is expanding beyond stablecoins.

Over the past two years, Tether has invested heavily into:

• Bitcoin mining
• AI infrastructure
• Energy production
• Treasury companies
• Financial services
• Emerging market payment rails.

The company already holds tens of billions in U.S. Treasuries backing USDT, but it has increasingly redirected profits into Bitcoin-focused strategic investments.  Tether CEO Paolo Ardoino described Twenty One Capital as one of the most important opportunities to build a Bitcoin-native public company “from the ground up.” 

SoftBank’s Exit Reflects a Strategic Shift

SoftBank originally joined the venture as a minority strategic investor, bringing institutional credibility and technology investment experience during Twenty One Capital’s launch phase.  However, the company’s exit suggests Tether now wants tighter alignment around a pure Bitcoin-focused operating strategy.

The transition comes as Twenty One Capital reportedly explores additional mergers and integrations tied to:

• Bitcoin mining
• Payment infrastructure
• Financial products
• Strike’s Lightning Network ecosystem.

The Bigger Picture

Tether buying out SoftBank’s stake reflects a larger shift happening across crypto: major stablecoin issuers are evolving into full-scale financial conglomerates. What started as a company issuing dollar-backed tokens is now becoming deeply involved in:

• Bitcoin treasury infrastructure
• Public markets
• Mining
• Capital formation
• Financial services.

At the same time, Twenty One Capital represents a growing trend of companies attempting to build entire public businesses around Bitcoin-native economics rather than traditional fiat financial models. The broader implication is becoming clearer: the next phase of crypto may not just be about tokens or exchanges—it may revolve around building fully integrated Bitcoin and stablecoin-powered corporations that operate directly inside public financial markets.
