Tether has acquired SoftBank Group's stake in Twenty One Capital, a company specializing in Bitcoin asset reserves, expanding into lending, mining, and capital markets services. The acquisition, announced on Wednesday, involves approximately 26% of SoftBank's shares, though the transaction amount remains undisclosed. This move enhances Tether's control over one of the largest publicly listed Bitcoin holders, as SoftBank's representative exits the board. The acquisition comes amid market challenges for Twenty One Capital, with Bitcoin's declining price impacting its asset value. Despite these pressures, the company's stock rose 4% following the announcement, partially recovering from a 37% decline since its NYSE debut. Twenty One Capital plans to evolve from a Bitcoin treasury model to a broader financial services company, integrating treasury operations with lending, mining, and capital markets activities.
