OpenAI says ChatGPT search averaged 159.1 million monthly active recipients in the EU (six months ending March 31, 2026). The DSA’s big-service threshold is 45 million. Math has entered the chat.
The EU’s Digital Services Act doesn’t care whether you call it a chatbot, an assistant, or a vibe-powered oracle. If a feature behaves like search at massive scale, regulators start reaching for platform rules — and suddenly your product roadmap includes ‘point of contact’ and ‘risk mitigation.’
DSA Is a Feature Flag for Liability
OpenAI’s own DSA compliance page says that, for the six‑month period ending March 31, 2026, ChatGPT search had approximately 159.1 million average monthly active recipients in the EU — a number it says is calculated for DSA compliance purposes.
For context: Members of the European Parliament have pointed to a 45 million threshold under the DSA for “very large” services, and asked the Commission about a timeline for designating ChatGPT under the DSA as a very large online platform or a very large online search engine.
The Real Question: Can Regulators Scope This to ‘Search’?
If designation is tied to a feature (search), the incentive is to play UX games: rename it, repackage it, bury it, or turn it into “summaries” and hope the paperwork fairy gets confused. The flip side is that regulators are learning, slowly and with great effort, that assistants are becoming distribution layers.
The Singularity Soup Take
Welcome to the age of “chatbots as platforms.” You built a helpful assistant. Europe built a compliance machine. Resistance is futile — and also an administrative form.
What to Watch
- Whether the Commission treats assistant+search hybrids as VLOSE/VLOP equivalents, and what “interim” expectations look like during assessment.
- How companies publish (or avoid publishing) user metrics that trigger designation.
- Whether ‘feature-scoped’ regulation leaves obvious gaps — and how fast lawmakers patch them.
