Decision to combine this investigation with the CMA’s investigation into Google’s conduct in ad tech

10 March 2023: The CMA has been conducting a separate investigation into whether Google has abused a dominant position through its conduct in relation to ad tech (Case 51145).

Following its decision to close its investigation into an agreement between Google and Meta (see below), and due to the interrelationship of the facts and conduct in the two investigations, the CMA has taken the decision to combine the remaining part of this investigation (Case 51134) – concerning whether Google’s conduct in relation to header bidding services was an abuse of a dominant position under Chapter II of the Competition Act 1998 – with the CMA’s investigation into Google’s conduct in ad tech.

As a result, the CMA has closed this investigation. Updates on the combined investigation will be provided on the case page for the CMA’s investigation into Google’s conduct in ad tech.

Administrative priorities decision

10 March 2023: The CMA has decided on administrative priorities grounds to close its investigation into whether Google and Meta entered into an anti-competitive agreement under Chapter I of the Competition Act 1998. As a result, the CMA is no longer investigating Meta in this case.

The CMA is continuing to investigate whether Google has abused a dominant position through its conduct in relation to header bidding services under Chapter II of the Competition Act 1998. That investigation includes whether Google has abused a dominant position through its agreement with Meta.

Case Information

On 10 March 2022, the CMA launched an investigation under Chapter I and Chapter II of the Competition Act 1998 into suspected breaches of competition law by Google and Meta. The investigation concerns an agreement between Google and Meta in relation to Meta’s use of Google’s header bidding product. The CMA is also investigating whether Google’s conduct may have affected the ability of other firms to compete with its header bidding product.

Notes

  • The investigation was opened Chapter I of the Competition Act 1998 in relation to Google and Meta, and under Chapter II of the Competition Act 1998 in relation to Google. In March 2023, the CMA decided on administrative priority grounds to close the Chapter I investigation into whether Google and Meta entered into an anti-competitive agreement. In light of that decision and due to the interrelationship of the facts and conduct in the 2 investigations, the CMA has taken the decision to combine the Chapter II investigation into Google’s conduct in relation to header bidding services with the CMA’s investigation into Google’s conduct in ad tech (Case 51145): visit the Google ad tech case page for further information.
