On March 23, 2026, artificial intelligence firm OpenAI made a formal request to UK regulators, urging them to mandate Google to include ChatGPT as a selectable search engine option for users on Android devices and web browsers. According to the open search market regulations put forward by the UK's Competition and Markets Authority, Google is obligated to present a selection screen within the Chrome browser and Android operating system, enabling users to pick their preferred default search engine. OpenAI contends that ChatGPT should be among the available choices for users, akin to conventional search engines like Microsoft Bing. Presently, although users have the option to set ChatGPT as their default search engine in Chrome, this process necessitates the installation of additional software and is not proactively offered by Google. Previously, Google has encountered antitrust investigations in the United States due to Chrome's prevailing market position. OpenAI's action is aimed at contesting Google's supremacy in the search sector, signifying the formal debut of AI-driven search into the global primary traffic gateway.
