The European Commission has formally designated ChatGPT as a very large online search engine under the Digital Services Act, making it the first AI chatbot to fall under the law's jurisdiction. The move extends a regulatory framework built around social media giants into territory it has never previously covered: a generative artificial intelligence assistant.
Reddit and Roblox were designated simultaneously, both as very large online platforms under the same legislation. All three services crossed the threshold of 45 million average monthly users in the European Union that triggers designation under the act. They now have four months to comply with a set of enhanced obligations.
The Digital Services Act came into force across the EU bloc in February and has already been applied to companies including TikTok and Meta. Its strictest requirements apply to the largest platforms and, now, to the largest search engines, including AI-powered ones. ChatGPT's designation as a very large online search engine, rather than as a very large online platform like Reddit and Roblox, reflects how regulators are trying to fit a new category of technology into an existing legal structure. Whether that categorical distinction will produce meaningfully different compliance obligations in practice is not yet clear.
The obligations that apply to all three platforms are substantial. Each must assess and mitigate systemic risks across six areas: the dissemination of illegal content, negative effects on minors, harm to users' physical and mental well-being, threats to fundamental rights, risks to electoral processes, and threats to public security. The requirements are designed to force platforms to look beyond individual pieces of harmful content and examine the structural risks their services may create at scale.
Technology commissioner Henna Virkkunen said the designations mean ChatGPT, Reddit, and Roblox will be held to a higher standard of scrutiny and accountability in the European Union.
Supervision of ChatGPT and Reddit will be carried out by the European Commission in cooperation with Ireland's Coimisiún na Meán, the Irish media regulator. Roblox will be supervised jointly with the Dutch Authority for Consumers and Markets. The multi-jurisdictional structure reflects a broader principle in EU digital regulation: national authorities in the member state where a company is established take a leading role, with the Commission retaining oversight.
The strategic logic of the ChatGPT designation is best read as a statement of intent. By classifying an AI chatbot as a search engine, rather than waiting for new AI-specific legislation to mature, the Commission has found a way to impose its most demanding compliance obligations on a fast-growing AI service without a legal gap. The AI Act, the EU's dedicated framework for artificial intelligence, is still being implemented in stages. The DSA designation fills that window.
OpenAI's ChatGPT now faces a compliance clock. How the designation will affect the product's features or operational practices inside the EU remains to be seen. Enforcement consequences for falling short within the four-month window have not been specified publicly. What is clear is that regulators elsewhere are watching: a workable model for designating an AI chatbot under existing digital law, with defined risk categories and a named supervisory structure, now exists and has been tested.
