The CEO of Tether recently revealed that the company's investment portfolio now includes over 120 companies, and this number is expected to grow significantly in the coming years. These investments are entirely funded by Tether's own profits, completely separate from the reserves of stablecoins like USDT, and are managed by the Tether Investments department.

Tether Investments is the company registered by Tether in El Salvador, focusing on strategic investments across multiple areas intersecting technology, infrastructure, and practical applications. Its investment portfolio covers artificial intelligence, financial services, energy, biotechnology, education, and digital media, and holds strategic equity in industries such as commodities, remittances, sports, and entertainment, expanding its business scope beyond stablecoins.

The Tether Q1 2025 report indicates that through Tether Investments, strategic investments have continued, with over $2 billion invested in long-term projects in areas such as renewable energy, artificial intelligence, peer-to-peer communication, and data infrastructure, dedicated to building a sustainable digital economy.
