The European Commission has classified ChatGPT as a very large online search engine and Reddit and Roblox as very large online platforms, since each reaches at least 45 million average monthly users in the EU. The three services now have until January 2027 to meet added obligations.
On 31 August 2026 the European Commission designated ChatGPT as a very large online search engine and Reddit and Roblox as very large online platforms under the Digital Services Act. The classification follows the companies own reporting that each service reaches at least 45 million average monthly users in the European Union. From the date of notification the three services have four months, until January 2027, to meet the additional obligations that apply to this category.
The added duties include risk assessments, external audits and transparency reporting. Each provider must assess and mitigate systemic risks such as the spread of illegal content, harm to minors, effects on physical and mental wellbeing, impacts on fundamental rights, election integrity and public security. For companies that rely on ChatGPT, Reddit or Roblox in their own workflows, the designation adds a new compliance factor to vendor and partner reviews.
It remains open how closely the Commission will monitor the deadline and what penalties apply if a provider misses it. Companies that use these services as a marketing channel or as infrastructure should watch for the first transparency reports, due once the new rules take effect in January 2027.
What this means for decision-makers
- Check whether your company counts as a business partner of ChatGPT, Reddit or Roblox under the new transparency rules.
- Track the January 2027 deadline and the risk assessments the three providers must publish by then.
- Review which marketing and sales workflows depend on these now more heavily regulated platforms.
