Along with ChatGPT, the European Commission also announced that Reddit and Roblox are considered Very Large Online Platforms, subjecting them to the same rules. The DSA restricts platforms from targeting ads to minors or using a person’s sexual orientation, religion, ethnicity, or political beliefs. It requires them to provide more transparency about how their recommendation algorithms work, too.

Under the DSA, online platforms and search engines are considered “Very Large” once they reach at least 45 million average monthly users in the EU. ChatGPT, Reddit, and Roblox have until the end of December 2026 to comply with the rules.

“These new designations mean that ChatGPT, Reddit and Roblox will now be held to a higher standard of scrutiny and accountability in the European Union, in line with their large impact on our citizens and society,” Henna Virkkunen, EU executive vice-president for tech sovereignty, security and democracy, says in the announcement.
