The U.S. Treasury Department proposed broader limits on American investments in artificial intelligence and other advanced technologies tied to China, Russia, North Korea and other countries of concern on October 22, 2026. The proposal would expand efforts to stop U.S. investment from supporting foreign military and surveillance capabilities.
New technology categories covered
The proposed rule would cover transactions involving semiconductor technology, quantum information systems, artificial intelligence, high-performance computing, supercomputing and hypersonic systems. Treasury also added biotechnology, saying it can support military, intelligence, surveillance or cyber capabilities. The proposal refers to the AI category as “superintelligence systems.” (U.S. Treasury announcement)
Under the proposal, some transactions would require notification to Treasury, while others would be prohibited. The rule would apply to U.S. persons, including certain controlled foreign entities. It would also establish technical definitions for the covered technologies. Treasury said the proposal is intended to provide clearer rules for investors and companies.
Investors face wider compliance duties
The Associated Press reported that the proposal would apply to investments above $50,000 but exclude many financial investments, including stock purchases. It would build on restrictions created in 2023 and expanded by Congress in the Comprehensive Outbound Investment National Security Act, which passed in December 2025. (Associated Press report)
The broader scope could affect venture capital funds and technology companies that invest in or work with advanced-technology firms overseas. It could also require more screening of ownership structures, business activities and technology capabilities before an investment is completed.
Final rule still pending
The proposal is not yet final. Treasury is accepting public comments and will publish implementing regulations later, including an effective date. Until then, the existing Outbound Investment Security Program remains in effect, according to Treasury’s program guidance.
The final regulations will determine which commercial AI and computing projects require notification, which are barred, and how much compliance work companies must perform before sending capital abroad.
