Tether Buys Out SoftBank Stake in Twenty One Capital as Bitcoin Treasury Competition Intensifies

Tether has acquired SoftBank’s minority stake in Twenty One Capital (NYSE: XXI), tightening its control over the publicly traded Bitcoin treasury firm as competition among institutional crypto investment vehicles continues to expand.

The transaction, disclosed on May 20, removes SoftBank representatives from Twenty One Capital’s board and leaves Tether as the dominant shareholder in a company built around large-scale Bitcoin accumulation and related financial operations.

The move comes less than six months after Twenty One Capital entered public markets through a SPAC merger with Cantor Equity Partners. At launch, the company disclosed holdings of more than 43,500 BTC, valued at roughly $4 billion at the time, placing it among the world’s largest corporate Bitcoin holders.

SoftBank Steps Away From Bitcoin Treasury Venture

SoftBank joined Twenty One Capital during its formation stage in late 2025, when institutional interest in Bitcoin treasury companies was accelerating following the approval and expansion of spot Bitcoin exchange-traded funds across several global markets.

The Japanese investment conglomerate held a minority position reportedly tied to approximately 10,500 BTC and maintained representation on the company’s board following the merger. Its exit reflects a broader trend among traditional institutional investors reassessing exposure to volatile crypto-linked equities after sharp swings in digital asset markets during the first half of 2026.

While SoftBank has historically invested heavily in emerging technology sectors through its Vision Fund businesses, the company has taken a more selective approach toward crypto-related investments in recent years following losses tied to several high-risk growth bets. Amid shifting institutional strategies, even narratives around Capital B Bitcoin treasury expansion highlight how firms are increasingly competing to scale Bitcoin-focused balance sheet strategies.

The board departures associated with the deal also simplify governance inside Twenty One Capital at a time when the company is pursuing a more aggressive Bitcoin-centered expansion strategy.

Tether Expands Influence Beyond Stablecoins

The acquisition further extends Tether’s reach beyond its core stablecoin business and deeper into Bitcoin infrastructure and treasury operations. Best known as the issuer of USDT, the world’s largest stablecoin by market capitalization, Tether has increasingly used profits from its reserve operations to expand investments across Bitcoin mining, energy production, lending, and treasury management businesses.

Industry analysts have viewed Twenty One Capital as part of that broader strategy. In fact, the company is increasingly being discussed alongside emerging models like the Southeast Asia first licensed Bitcoin treasury, which signals how regulated Bitcoin treasury frameworks are beginning to evolve across different regions.

Unlike companies that primarily hold Bitcoin as a treasury reserve asset, XXI has attempted to position itself as a broader Bitcoin operating business with exposure to capital markets activity, infrastructure, and financial services tied directly to the Bitcoin ecosystem.

Earlier this year, the company explored a possible integration involving businesses connected to Bitcoin entrepreneur Jack Mallers, including Strike and operations linked to Elektron Energy. The proposed structure aimed to combine Bitcoin treasury accumulation with mining, payments infrastructure, and lending services.

Public Bitcoin Treasury Firms Face Growing Pressure

The deal arrives as public Bitcoin treasury firms face increasing scrutiny from investors over sustainability, leverage exposure, and long-term profitability. Companies following Bitcoin accumulation strategies have seen share prices move closely alongside BTC market volatility, with investor sentiment often shifting rapidly during broader crypto market corrections.

While MicroStrategy remains the most prominent corporate Bitcoin holder, a growing number of firms have attempted to replicate or expand on that model by building dedicated treasury businesses around Bitcoin ownership. Some analysts argue these companies provide institutional investors with indirect exposure to Bitcoin through equity markets, while critics question whether treasury-focused firms can maintain growth during prolonged periods of crypto market weakness.

For Tether, full control of Twenty One Capital could provide greater flexibility to pursue acquisitions, raise additional capital, or expand Bitcoin holdings without the complexity of competing shareholder priorities. Investors are expected to watch closely for any changes to the company’s treasury strategy, future BTC purchases, or broader restructuring plans in the coming months.
