The Justice Department's antitrust chief issued a stark warning to dealmakers attempting to use artificial intelligence disruption as a legal defense during merger reviews. Acting Assistant Attorney General Omeed Assefi told companies at a New York University event that claims of AI replacing entire industries must be supported by concrete evidence, signaling heightened scrutiny of AI-related merger arguments.

DOJ Antitrust Head Issues Warning on AI Claims

The DOJ antitrust division is putting companies on notice about using AI as a convenient excuse during merger reviews. Acting Assistant Attorney General Omeed Assefi, who oversees the Justice Department's merger review process, delivered pointed remarks at New York University that signal a new level of scrutiny for dealmakers invoking artificial intelligence disruption. His message was direct: regulators can distinguish between legitimate competitive concerns and misleading claims designed to smooth approval processes.

Artificial Intelligence Disruption Requires Concrete Evidence

"We know you will be tempted to tell us that AI is replacing your industries. We get it. We hear that a lot," Assefi stated, according to prepared remarks

. The warning addresses a growing trend where companies attempt to justify business deals by arguing that AI-driven market changes make consolidation necessary for survival. However, the DOJ antitrust head made clear that such assertions must be supported by concrete evidence rather than speculative forecasts or vague references to technological change

Heightened Scrutiny for Merger Reviews

The remarks reflect broader concerns about antitrust enforcement in an era where AI dominates corporate strategy discussions. While Assefi emphasized that merging parties remain welcome to engage with his division at any point during merger reviews, he drew a clear line against attempts at deception

. "We know when you are trying to mislead us," he warned, suggesting the division has developed methods to evaluate the validity of claims of AI disruption. This statement matters because it signals that regulators are building expertise in tech policy and won't accept AI buzzwords as substitutes for substantive competitive analysis.

What This Means for Dealmakers and Tech Policy

For companies planning mergers, this warning from Omeed Assefi represents a critical shift in how they should prepare their legal defense strategies. The Justice Department appears determined to prevent AI from becoming a catch-all justification that obscures genuine antitrust concerns. Dealmakers now face the challenge of assembling detailed, data-driven evidence if they intend to argue that artificial intelligence is fundamentally reshaping their competitive landscape. Short-term, expect longer review timelines as companies scramble to substantiate AI-related claims. Long-term, this approach could establish precedents that shape how regulators worldwide assess technology-driven market changes during antitrust enforcement actions. Companies should watch for follow-up guidance on what types of evidence the DOJ considers credible when evaluating misleading claims about technological disruption.
