The EU Designates ChatGPT a Very Large Online Search Engine Under the DSA
On August 31, 2026, the European Commission designated ChatGPT a Very Large Online Search Engine—the first AI chatbot in the DSA’s strictest tier—after measuring ~159.1 million average monthly EU users, with four months to comply and fines up to 6% of global turnover.
TLDR
The European Commission on Monday, August 31, 2026 designated ChatGPT a Very Large Online Search Engine (VLOSE) under the Digital Services Act—the first AI chatbot in that tier. Same package: Reddit and Roblox as VLOPs. Threshold: ≥45 million average monthly EU users. ChatGPT search AMAR: ~159.1 million for the six months ending 31 March 2026. Four months to comply: systemic-risk assessments (illegal content, minors, wellbeing, elections, public security), researcher data access, ad archive. Fines up to 6% of global turnover. Henna Virkkunen: higher scrutiny “in line with their large impact.” Legal theory: web search inside the chatbot = search engine.
What the designation does
| Item | Commission 31 Aug 2026 |
|---|---|
| Status | VLOSE (not VLOP) |
| Clock | 4 months to the full obligation set |
| Peers named | Reddit, Roblox as VLOPs |
| Not | An AI Act GPAI decision (that clock started Aug 2) |
Product-line de-dupe: not Aug 2 AI Act enforcement, not Aug 18 ChatGPT Ads Europe. Different statute, different clock.
Why this story matters
Brussels just treated ChatGPT search as Google-scale infrastructure. That pulls ads, ranking, and researcher access into DSA process just as OpenAI prints $1B ads ARR. Watch: OpenAI’s risk-assessment filing, and whether Claude / Gemini get the same label next.
