AI Forces Antitrust Authorities to Reevaluate Enforcement Toolkits
Artificial intelligence is prompting regulators worldwide to rethink how they apply antitrust laws.
AI’s rapid integration into business models is reshaping competitive dynamics, leading antitrust and competition authorities across the globe to question whether their existing enforcement frameworks are adequate. A November 2026 briefing by Perkins Coie highlights how regulators in the U.S., EU, U.K., and other jurisdictions are exploring new policy tools, such as AI‑specific metrics for market dominance and real‑time monitoring of algorithmic collusion. The guidance stresses that traditional merger review criteria and digital marketplace oversight may no longer capture the speed and opacity of AI‑driven transactions. For law firms advising clients in tech, fintech, and platform industries, understanding these evolving toolkits is critical. Firms should advise clients to review current AI governance practices, assess potential antitrust risks, and engage proactively with regulators to align AI strategy with emerging enforcement expectations. The next development to watch is the release of jurisdictional white papers and regulatory frameworks that may codify these new enforcement mechanisms.
