EU classifies ChatGPT, Reddit and Roblox under its strictest platform regulations
The European Commission has classified ChatGPT as a Very Large Online Search Engine (VLOSE), and Reddit and Roblox as Very Large Online Platforms (VLOPs). This requires them to comply with the EU's toughest regulations under the Digital Services Act.

What happened?
The European Commission has designated OpenAI's ChatGPT as a Very Large Online Search Engine (VLOSE) and Reddit and Roblox as Very Large Online Platforms (VLOPs) under the Digital Services Act (DSA). The decision, taken on 10 March 2025, follows the platforms exceeding the threshold of 45 million monthly active users in the EU. This means the companies must comply with the EU's most rigorous regulatory framework for digital platforms.
Key facts
Why it matters
Classification as a VLOP or VLOSE entails strict requirements for risk assessments, mitigation of disinformation and systemic risks, and increased transparency regarding algorithms. The platforms must also provide independent audits and prevent minors from being exposed to harmful content or manipulative design patterns.
Who is affected?
The decision affects the parent companies OpenAI, Reddit, and Roblox, which are now required to implement more comprehensive audits of their services. Users in the EU and Sweden will receive enhanced protection against illegal content, harmful recommendation algorithms, and targeted advertising towards minors.
Impact on the EU
The decision was made at the EU level, with the European Commission imposing strict requirements on the three services under the Digital Services Act. ChatGPT, Reddit, and Roblox must now follow the same stringent regulations on transparency and risk management that have previously been applied to other tech giants in the EU.
What else you should know
The designations of VLOSE for ChatGPT and VLOP for Reddit and Roblox are based on the platforms reaching the threshold of at least 45 million active monthly users within the EU. The services now have four months to align their systems with the new requirements.
