The United Kingdom's competition regulator has unveiled proposals that would give users greater control over which search they use on Google's Android operating system and Chrome browser, in a move intended to open the door to rival platforms at a time when AI-powered assistants such as ChatGPT and Perplexity are drawing users away from traditional search.

The Competition and Markets Authority (CMA) is pushing Google to display search alternatives in a manner that gives competing platforms a meaningful opportunity to attract users. The measures are intended to make it easier for people to find and switch to alternative search services, including emerging AI-powered options. The proposals are set out in a consultation document published on the UK government's website.

Regulatory Focus on Choice Architecture

The initiative forms part of the UK's comprehensive digital markets framework, implemented after Google was classified in October 2025 as holding strategic market status in general search and search advertising. That designation empowers the CMA to impose specific behavioral obligations on the company.

At the center of the proposal is Google's “choice architecture” — the methodology through which search alternatives are presented to users, and how that presentation shapes consumer behavior. The CMA is scrutinizing whether Android and Chrome users require enhanced capabilities to designate their preferred search provider. The stakes of that design question are considerable: because presentation shapes behavior, the prominence a search service receives inside Android and Chrome can influence which platforms users ultimately adopt — the very lever the CMA is targeting.

Such changes could boost exposure for both established search competitors and AI-powered alternatives. Services such as ChatGPT, developed by OpenAI, and Perplexity are increasingly challenging traditional search models by delivering direct responses to queries instead of link-based results.

The authority initially launched consultations on user-choice requirements in January and has since refined its approach based on stakeholder input and evolving market dynamics. The public comment period runs through October 9, 2026.

Additional Regulatory Measures Already in Effect

The user-choice initiative comes alongside multiple other regulatory actions imposed on Google throughout the current year. In June, the CMA established a publisher conduct requirement granting content creators enhanced authority over how their materials appear in Google Search, encompassing AI-enhanced functionalities.

The watchdog also mandated fair-ranking protocols and data-portability standards. The portability obligation compels Google to supply approved third-party providers with mechanisms enabling UK consumers to transfer their search history without cost.

Taken together, the interventions demonstrate that the CMA is addressing not merely Google's search market dominance, but also the potential impact of emerging AI technologies on competitive dynamics.

AI-Powered Search Reshapes Competition

The emergence of AI-driven assistants has fundamentally altered the competitive environment for online information retrieval. Users now turn to platforms such as ChatGPT and Perplexity for research, guidance, and immediate answers that would traditionally have begun with a Google query. If adopted, the measures would shape how easily someone setting up an Android device or using Chrome in the UK can designate an AI assistant rather than a conventional search engine as their default.

The CMA's current proposal is a preliminary measure rather than a definitive mandate. The authority is soliciting public input before finalizing whether and how user-choice regulations should be implemented.

For Alphabet, Google's parent company, these developments carry substantial significance given that Google Search constitutes a fundamental revenue stream. Enhanced default-selection options across Android and Chrome could enable competitors to capture market share if consumers receive more prominent exposure to alternative search engines and AI platforms.

Subsequent actions will hinge on the results of the consultation. The next milestones to watch are the close of the comment period and the CMA's response, which will determine whether the proposals harden into binding conduct requirements. The UK regulator has made clear that search market competition will increasingly encompass both conventional search engines and AI-powered assistants moving forward.
