Treasury proposed updated rules requiring notification or prohibiting certain U.S. investments involving foreign persons and strategic technologies, including AI.
The U.S. Department of the Treasury on October 22 proposed updates to its Outbound Investment Security Program, including rules covering certain U.S. investments involving artificial intelligence systems and other strategic technologies. The proposal implements the Comprehensive Outbound Investment Security Act, enacted as part of the Fiscal Year 2026 National Defense Authorization Act, and would require notifications for some transactions while prohibiting others.
The proposed framework covers transactions involving specified foreign persons engaged in designated technologies. In addition to AI, the law identifies semiconductors and microelectronics, quantum information technologies, high-performance computing and supercomputing, and hypersonic systems. Treasury also proposed adding biotechnology. The department’s notice describes technical parameters, covered transaction categories, exceptions, notification information, due-diligence expectations, and potential penalties. Treasury says the rules are intended to address national-security risks from U.S. investment that could support military, intelligence, surveillance, or cyber capabilities abroad.
This is a proposal, not a final rule. Treasury is seeking public comments on the scope and definitions, notification requirements, and enforcement provisions. The department says it will consider feedback before issuing final implementing regulations; the final rules will establish an effective date. Businesses and investors should therefore distinguish the proposed requirements from obligations currently in force and review the official notice for the precise transaction definitions and exceptions.
For AI companies, investors, and compliance teams, the proposal could make some cross-border financing and strategic partnerships subject to additional screening or reporting, depending on the parties, technology, and transaction. The practical effect will turn on the final definitions and thresholds, as well as the treatment of exceptions. Companies with international investment activity may want to identify potentially covered dealings and monitor the rulemaking, while avoiding assumptions that every AI-related investment is covered. Treasury’s release says comments are due by the deadline specified in the official proposed rule.
