The issuer of the USDT stablecoin has placed its bets on the growing importance of artificial intelligence in the field of health.
Tether has announced a strategic investment in Eight Sleep, a developer of “smart sleep systems.” The company manufactures beds, mattresses, and other sleep products with artificial intelligence that adapt in real time to the user's physiology by analyzing data from built-in sensors.
Tether is known as the issuer of the largest dollar-pegged stablecoin, USDT, and the market leader in tokenized gold, Tether Gold (XAUT). The company's net profit for 2025 exceeded $10 billion. The company did not disclose the amount of its investment in Eight Sleep, but said the AI startup is valued at $1.5 billion.
Tether is betting on the growing importance of AI in medical development. Technologies that can turn health data streams into concrete practical ideas “will define the future of consumer health,” the press release said.
Tether has its own AI project, QVAC. The investment in Eight Sleep followed the recent launch of Tether QVAC Health, a personal wellness platform designed to collect data on physical fitness and health from smart gadgets and apps. According to Tether, this is done while “maintaining individual control” on the part of the user.
Tether's investment is aimed at expanding Eight Sleep's capabilities, including the use of QVAC architecture and capabilities. According to Tether CEO Paolo Ardoino, Eight Sleep could define the future of healthcare technology with AI that constantly monitors the user's condition.
“We are entering an era of intelligent healthcare systems focused on human well-being,” Ardoino said. Eight Sleep has promised that “sleep was just the beginning.”
Tether mines bitcoins, accumulates physical gold, and its investment portfolio includes investments in artificial intelligence, financial services, energy, biotechnology, education, and media, as well as commodities, money transfers, sports, and entertainment. At the end of 2025, Tether invested in humanoid robots, supporting Italian developments in AI and robotics.
