On September 4, 2026, the UK Competition and Markets Authority (CMA) issued a provisional finding that Alphabet Inc. has abused its dominant position in the digital advertising technology market. The regulator concluded that Google’s self--preferencing of its AdX exchange has harmed competition for UK publishers and advertisers. The CMA is considering enforcement measures, including a potential fine of up to 10% of global revenue and a mandate for the operational separation of its ad--tech business. Alphabet has until October 25, 2026, to respond to the findings before a final decision is reached.
