The UK Competition and Markets Authority (CMA) has announced statutory regulatory interventions under the Digital Markets, Competition and Consumers Act 2024 (DMCCA) specifically addressing autonomous “Agentic AI” systems. As artificial intelligence models transition from passive assistants to autonomous agents executing transactions, bookings, and commercial contracts on behalf of users, the competition regulator is moving to prevent consumer exploitation, hidden commissions, and anti-competitive ecosystem lock-in.
Prohibiting algorithmic bias and autonomous steering
The CMA’s enforcement framework establishes binding legal boundaries for platforms deploying autonomous purchasing and transaction agents in the UK:
- Ban on self-preferencing and hidden steering: Autonomous shopping and booking agents must not algorithmically steer consumers toward proprietary ecosystem services or commercial partners without unambiguous, prominent disclosure of financial incentives.
- Explicit confirmation for consequential transactions: While AI agents may research and prepare transactions, binding financial commitments above statutory thresholds require express, unmanipulated human confirmation, outlawing algorithmic inertia contracts.
- Interoperability and open switching: Dominant digital gatekeepers must allow consumers to deploy independent third-party AI agents without synthetic technical bottlenecks or exclusionary API restrictions.
Severe financial penalties and investigative powers
Under the newly active DMCCA regime, the CMA wields enhanced enforcement and sanction powers to ensure digital market fairness:
- Fines up to 10% of global turnover: Companies found guilty of employing manipulative algorithmic dark patterns or anti-competitive agent defaults face statutory fines reaching up to 10% of their worldwide annual turnover.
- Mandatory algorithm audits: The CMA’s Digital Markets Unit (DMU) holds legal authority to compel technology providers to disclose agent prompt architectures, ranking parameters, and training datasets during compliance investigations.
- Consumer redress orders: The regulator can directly mandate restitution payments to consumers harmed by deceptive algorithmic pricing or automated subscription traps.
