On October 22, 2026, the U.S. Treasury Department released a Notice of Proposed Rulemaking to implement the Comprehensive Outbound Investment National Security (COINS) Act. That matters because it signals how Treasury intends to police certain U.S. outbound investments into sensitive technologies and covered foreign persons—but it is still only a proposal. The current Part 850 regime continues until a final rule takes effect, and the final effective date has not yet been set. For founders, investors, corporate development teams, and compliance leads, the right response is not panic; it is a disciplined check of whether a deal sits inside the proposed perimeter.
- Written comments on the proposal are due December 7, 2026.
- The proposal applies to U.S. persons and also reaches certain controlled foreign entities.
- Covered transactions can include equity, contingent equity, certain debt with equity-like rights, joint ventures, greenfield or expansion activity, direction of some foreign-person transactions, and some limited-partner investments.
- Treasury proposes a distinction between prohibited technologies and notifiable technologies.
- A $50,000 de minimis amount is an exception from notification only; it is not a blanket safe harbor for prohibited deals.
- The proposal contemplates civil penalties and possible compelled divestment for prohibited transactions.
What changed, and what has not changed yet
What changed is the policy direction. Treasury has proposed detailed rules for outbound U.S. investment screening in six technology areas: semiconductors/microelectronics, “super intelligence” systems, quantum, high-performance computing/supercomputing, hypersonic systems, and biotechnology. The proposal also clarifies the kinds of transactions and entities that could trigger review or notification, including certain foreign-person and controlled foreign entity structures.
What has not changed yet is the legal status. This is not the final operative rule. Until Treasury finalizes and the rule becomes effective, readers should continue to treat the current Part 850 framework as the governing regime. That distinction matters, especially for any team deciding whether to close, pause, restructure, or notify.
8 checks before your next AI or biotech deal
1) Is there a U.S. person or controlled foreign entity in the chain?
The proposed rule is not aimed only at deals signed inside the United States. It generally applies to U.S. persons, and it also creates obligations involving controlled foreign entities. That means a U.S. parent, U.S. fund sponsor, U.S. operating company, or other U.S.-linked decision-maker may bring the transaction inside scope even when the target, issuer, or vehicle is offshore. Teams should map the decision rights, ownership chain, and control features early rather than assuming the deal is “foreign” just because the counterparty is offshore.
2) Is the counterparty a covered foreign person?
The proposal focuses on covered foreign persons connected to countries of concern. Treasury’s current proposal includes China, including Hong Kong and Macau, as well as Cuba, Iran, North Korea, Russia, and Venezuela under the Maduro regime. Treasury has also publicly discussed Venezuela carefully, so teams should avoid oversimplifying the category and should confirm the exact scope in the current proposal rather than relying on a shorthand list. The practical question is not just where the entity is organized, but who owns it, controls it, and whether it has the relevant ties to a country of concern.
3) Is the transaction type covered?
Not every investment relationship is treated the same way. The proposal captures a range of transaction types, including equity and contingent equity, certain debt with equity-like rights, joint ventures, greenfield or expansion activity, direction of some foreign-person transactions, and certain limited-partner investments. The last point is especially important for funds, side letters, and sponsor-led structures. A passive label does not automatically make a transaction outside the rule if the actual rights or economics tell a different story.
4) Is the technology notifiable or prohibited?
Treasury proposes to distinguish between prohibited technologies and notifiable technologies. That is a crucial planning point. A notifiable deal may be allowed but require notice, while a prohibited deal may be barred entirely. The six technology areas are the core focus: semiconductors/microelectronics; “super intelligence” systems, which is Treasury’s proposed terminology for AI; quantum; high-performance computing/supercomputing; hypersonic systems; and biotechnology. A company should not assume that a broad sector label settles the question. The specific activity, product, model, platform, device, or use case matters.
5) Does an exception genuinely apply?
The proposal includes exceptions, but they are narrower than many deal teams expect. Publicly traded securities and registered investment-company securities are among the proposed exceptions, yet governance rights can affect whether an exception actually fits. In other words, the fact that something is public does not end the analysis if other rights or arrangements create a different regulatory profile. For limited-partner investments, the proposal also contemplates exceptions when committed capital does not exceed $2 million or when a specific binding contractual assurance applies. Those are careful, fact-specific carve-outs—not a general permission slip.
6) Is $50,000 being misread as a safe harbor?
This is one of the easiest points to misunderstand. The proposed $50,000 de minimis amount is aggregated across the preceding 12 months and is an exception from notification only. It is not a blanket safe harbor, and it does not excuse a prohibited transaction. In plain English: a transaction under that amount may avoid notification in some circumstances, but that does not mean it is automatically outside the rule, and it certainly does not mean a prohibited investment becomes permissible simply because the dollar value is low. Do not repeat the misleading shorthand that the rule “only applies above $50,000.”
7) What diligence and records are needed?
Because the proposal turns on facts that may not be obvious from a term sheet, documentation matters. Teams should preserve ownership charts, cap tables, side letters, governance rights, debt terms, board materials, diligence memos, and any analysis of the target’s technology. They should also document why an exception does or does not apply. That record becomes especially important if a transaction later changes form, if additional rights are granted, or if a team acquires knowledge after closing that changes the notification analysis. Treasury has proposed notifications generally due no later than 30 calendar days after completion, with similar timing after later acquisition of knowledge. That timing makes clean records more than a back-office exercise.
8) What deadlines and comment opportunities matter?
There are two deadlines to watch. First, written comments on the NPRM are due December 7, 2026. Second, if and when a final rule is issued, the effective date may differ from the proposal and is not yet set. Treasury also proposes non-binding feedback for eligible persons with a direct financial interest in an actual, non-hypothetical transaction. That means real transactions—not hypothetical screening exercises—may be able to seek feedback, but only within the scope Treasury allows. If your organization wants to influence the final rule, the comment window is now. If you want to clear a deal, you should not assume the proposal itself has already changed the law.
Could the proposed COINS rule touch your deal?
Answer these six questions with yes, no, or not sure. This is an educational self-check, not legal advice and not a determination.
- Is there a U.S. person, U.S. parent, or controlled foreign entity involved in the investment chain?
- Is the counterparty, target, or structure linked to a covered foreign person or a country of concern?
- Is the deal an equity, debt-with-rights, joint venture, greenfield, expansion, direction, or limited-partner transaction?
- Does the activity involve semiconductors, “super intelligence” systems, quantum, high-performance computing, hypersonics, or biotechnology?
- Could the deal fall inside a proposed exception, such as a public security or registered investment-company security, or a limited-partner carve-out?
- Are you unsure whether the $50,000 threshold, timing rules, or knowledge-based notice rules apply?
If you answered yes or not sure to one or more questions, the conservative result is usually higher review intensity. A simple guide is below.
- Lower apparent exposure: the transaction appears outside the proposal on multiple points, and no obvious covered foreign person, covered technology, or covered transaction type is present.
- Needs targeted review: one or more facts are uncertain, an exception may apply, or the structure is close to the line.
- High-priority counsel review: the deal likely involves a covered foreign person, a sensitive technology area, or a transaction type that may be covered or prohibited.
If the result feels ambiguous, that is the point. The quiz is meant to surface risk early, not to replace a formal analysis.
Short scenario table
- Public stock purchase in a listed semiconductor company: requires analysis. Public securities may be excepted, but governance rights, structure, and the company’s technology profile still matter.
- $40,000 direct investment in an AI startup: requires analysis. The amount alone does not end the inquiry, and the de minimis rule is not a blanket safe harbor.
- U.S. company joint venture with a covered biotech entity: requires analysis. Joint ventures are expressly within the proposed transaction list, and the technology area is directly relevant.
Practical action plan for the next 30 days
- Build a transaction map: identify all U.S. persons, controlled foreign entities, beneficial owners, and decision-makers involved in the deal.
- Classify the target or counterparty: determine whether it is linked to a country of concern and whether it qualifies as a covered foreign person.
- Test the technology category: confirm whether the activity touches one of the six proposed areas and whether it is proposed to be prohibited or notifiable.
- Check the deal form: review equity, debt, JV, expansion, LP, or directional rights carefully.
- Review possible exceptions: do not assume public status or LP status automatically resolves the issue.
- Create a document set: preserve rights, charts, diligence notes, and the rationale for the conclusion.
- Plan for timing: if the deal closes, calendar the proposed 30-day notification framework and any later knowledge-based trigger.
- Consider comment engagement: if your organization has a real-world issue, consult stakeholders now so any comment to Treasury is ready before December 7, 2026.
FAQ
Is this rule already effective?
No. Treasury issued a Notice of Proposed Rulemaking on October 22, 2026. That is a proposal, not the final rule. The final effective date has not yet been set, and the current Part 850 regime continues until a final rule takes effect.
Does it ban all U.S. investment in China?
No. The proposal is narrower than a blanket ban. It focuses on certain outbound investments tied to covered foreign persons and sensitive technology areas, with some transactions notifiable and others prohibited. Each deal still requires a fact-specific review.
Are public stocks automatically covered?
Not automatically. Publicly traded securities and registered investment-company securities are among the proposed exceptions, but governance rights and other facts can affect whether the exception applies. A public listing does not end the analysis by itself.
Can companies ask Treasury before closing?
Treasury proposes non-binding feedback for eligible persons with a direct financial interest in an actual, non-hypothetical transaction. That is not the same as a guaranteed pre-clearance, so companies should not treat it as a substitute for internal diligence or legal review.
Conclusion
The proposed COINS rule is a major signal for outbound investment strategy in sensitive technologies, especially for cross-border AI, biotech, semiconductor, quantum, computing, and hypersonics deals. But the key word is proposed. Until Treasury finalizes the rule and sets an effective date, teams should keep working from the current regime while preparing for the new framework. If your organization wants to shape the rule, the comment deadline is December 7, 2026.
