Regulators probe AI-driven pricing for illegal collusion risks

AI pricing tools face crackdown as regulators target algorithmic collusion

Competition watchdogs in the UK and Europe are stepping up scrutiny of AI-driven pricing tools. Authorities warn that algorithmic systems could enable illegal collusion between businesses. Recent investigations highlight growing concerns over how automated pricing software may break antitrust rules. The UK’s Competition and Markets Authority (CMA) has published a paper on agentic AI, warning of risks tied to autonomous pricing agents. These tools, used to optimise commercial strategies, could lead to anti-competitive outcomes—whether through classic collusion, predictable agent behaviour, or even self-coordinating AI systems.

The CMA has already taken action against two online poster sellers. They were found to have used automatic repricing software to fix prices, agreeing not to undercut each other. Meanwhile, an investigation into major hotel chains is underway over suspicions they shared sensitive pricing data via a third-party provider. In the EU, the European Commission has also made algorithmic pricing a priority. A recent probe uncovered four electronics manufacturers using price-monitoring software to enforce illegal resale price maintenance. The European Court of Justice further ruled that Lithuanian travel agents could be held liable if they knowingly used a shared booking platform’s algorithm to coordinate prices. Poland’s competition chief has confirmed parallel investigations into banking and pharmaceutical sectors. The focus is on whether algorithmic tools are being used to facilitate illegal price coordination.

Regulators are now treating AI-driven pricing as a key enforcement area. Businesses using automated tools must ensure compliance with competition laws. Failure to do so could result in penalties, as authorities crack down on algorithm-enabled collusion.
