Tether CEO Paolo Ardoino disclosed on July 23 that “its investment portfolio already covers more than 120 companies, and this number is expected to grow significantly in the coming months and years. These investments are all derived from Tether’s own profits (profits of $13.7 billion in 2024), which are completely isolated from USDT (and other stablecoins) reserves and are part of the business scope of the Tether Investments department.”

Tether Investments is a company established by Tether under the laws of the Republic of El Salvador, focusing on strategic investments in a wide range of areas where technology, infrastructure and practical utility intersect. Its investment portfolio covers artificial intelligence, financial services, energy, biotechnology, education and digital media, and holds strategic stakes in commodities, remittances, sports and entertainment, extending its reach beyond stablecoins.

Tether has five major sections on its official website: Finance, Power (renewable energy mining business), Data, Edu (education) and Evo (human evolution). From the layout of these five sections, it is not difficult to see Tether's strategic bet direction.

• Tether Finance is committed to promoting financial inclusion and improving global financial accessibility in areas where banking infrastructure is scarce or absent. This is reflected in stablecoins, Tether wallet development kits, asset tokenization, TradeFi, and investments.

• Tether Power focuses on the integration of renewable energy and Bitcoin mining;

• Tether Data develops artificial intelligence and P2P technology. Tether's support for initiatives such as Holepunch and Pears.com highlights Tether's support for peer-to-peer technology. The investment in Northern Data will help AI research and projects.

• Tether Edu is committed to expanding access to educational tools and resources. Tether's investment in the Academy of Digital Industries in Georgia and support for PlanB.Network are breaking down educational barriers and driving the gig economy.

• Tether Evo is committed to empowering humanity in the inevitable evolution of the future. Blackrock Neurotech, a Tether investment, is leading the development of neurotechnology, creating brain-computer interfaces, and opening up new areas of communication, rehabilitation, and cognitive enhancement.
