Twenty One Capital shares surged more than 6% in after-hours trading on Wednesday after its majority shareholder Tether proposed a three-way merger combining Twenty One Capital, Bitcoin payments company Strike, and Bitcoin mining firm Elektron Energy. Tether stated its intention to vote in favor of both proposed mergers, lending the weight of the world's largest stablecoin issuer to a deal that would create a vertically integrated Bitcoin financial operation under a single publicly traded entity. Twenty One Capital ended regular trading down 1.7% at $7.83 but climbed to a high of $9.28 after hours before settling at $8.35 as the market processed the announcement.

The strategic logic behind the proposed combination is clearly articulated by Tether. Strike contributes a profitable financial services platform with global distribution and regulatory infrastructure across multiple jurisdictions. Elektron Energy adds large-scale Bitcoin mining operations, execution depth, and operational infrastructure. Twenty One Capital provides the Bitcoin treasury accumulation platform and public market listing. Together the three components would form a company that spans the full Bitcoin value chain from mining production through payments infrastructure to institutional holding, backed by the financial resources and stablecoin distribution of Tether sitting behind all three. If the mergers proceed, the combined entity would represent one of the most ambitious attempts to build a diversified Bitcoin-native financial conglomerate yet attempted within the publicly traded equity market.
