Share with your CISO
Companies deploying AI systems right now are not choosing between the EU AI Act and U.S. state rules; they are subject to both simultaneously, and the frameworks measure fundamentally different things. Lowenstein Sandler partners Amy Mushahwar and Kathleen McGee lay out the core tension in AI compliance architecture: the EU regulates impact and risk category, the U.S. regulates disclosure and consent. Colorado already repealed and replaced its AI law, and the EU pushed major enforcement deadlines to 2027-2028, though its AI transparency requirements for chatbots went live in August 2025 on schedule.
What this means for your business
Any organization whose AI-generated content reaches EU users is inside the EU AI Act’s scope regardless of intent or headquarters, which is a larger population than most compliance teams have scoped. Companies that built programs around Colorado’s original law are already retooling. The organizations best positioned are those that treated AI compliance the way mature security teams treat security controls: build strong, documented controls first, then map them to whichever framework applies, rather than building to any single regulation’s checklist.
The deeper problem is that the EU and U.S. frameworks are not just different in degree, they are different in kind. EU compliance demands a risk classification exercise for every AI use case, the kind of structured impact analysis that sits closest to the CISO’s existing risk management function. U.S. compliance today is mostly a disclosure and consent documentation problem, closer to privacy counsel’s turf. A single AI compliance program that ignores this split will either over-engineer consent flows for EU purposes or under-document risk assessments for U.S. state auditors. The practical answer is a unified evidence library that feeds both frameworks, not a single policy document pretending the requirements are the same.
The August 2025 chatbot transparency deadline is the leading indicator worth watching. It is the first hard EU AI Act requirement with real operational bite, and organizations that missed it are now remediating under a live rule, not a future one. If your vendor contracts for AI tools do not yet assign responsibility for that disclosure obligation, that is the renewal clause to revisit before the 2027 wave of broader EU enforcement arrives.
Concept deep-dive: Risk-based vs. disclosure-based regulation
Risk-based regulation, the EU’s model, prohibits or conditions certain AI uses based on what the system does and to whom, the way aviation law categorizes aircraft by their potential to cause harm. Disclosure-based regulation, the dominant U.S. approach, requires telling users what data is collected and how AI is involved, but generally permits the underlying activity. The distinction matters operationally because risk-based compliance requires product-level decisions, while disclosure compliance is mostly a documentation and consent-flow problem.
