Tether, the issuer behind the world’s largest stablecoin USDT, has revealed major details about how it has been deploying its profits—and the numbers are turning heads.
According to CEO Paolo Ardoino, Tether has invested approximately $5 billion into U.S.-based companies over the past two years, signaling a deep and growing integration with the American economy.
Strategic Stakes in U.S. Tech and Innovation
Tether’s investment arm, Tether Evo, has made high-profile moves into both digital media and frontier technologies. In early 2025, the company invested $775 million in video-sharing platform Rumble, acquiring over 103 million shares of the company’s Class A Common Stock. In 2024, it also became the majority shareholder in Blackrock Neurotech, a brain–computer interface company, following a $200 million investment.
These ventures indicate Tether’s desire to diversify beyond its core stablecoin business and back companies aligned with its vision of digital freedom and alternative infrastructure.
Bitcoin Mining and the OCEAN Pool
In the crypto mining sector, Tether has grown its influence steadily. It recently expanded its stake in Bitdeer, a major Bitcoin mining company, to 21%, establishing itself as one of the firm’s largest shareholders. Additionally, Tether is redirecting hash power from its mining activities to support the OCEAN mining pool, part of its efforts to decentralize BTC mining infrastructure.
A Giant in U.S. Treasury Markets
Beyond venture capital and crypto infrastructure, Tether holds a staggering $120 billion exposure to U.S. Treasuries, making it the 19th-largest holder of U.S. debt globally. This places the company ahead of major nations like Germany ($111.4B) and the United Arab Emirates ($104.4B).
Ardoino emphasized this exposure as a signal of Tether’s confidence in and reliance on the U.S. economy. It also reinforces the idea that stablecoins like USDT are intricately linked to traditional financial systems, despite operating in the decentralized world of crypto.
In sum, Tether’s investments reveal a broad and strategic approach — backing both emerging tech and legacy financial instruments — as it cements its role as a powerhouse within both the digital and traditional economic ecosystems.
