EU designates ChatGPT, Reddit, Roblox as very large platforms under Digital Services Act
They must now assess and mitigate risks to illegal content, child safety, and mental health.
Mark
So these three platforms just hit 45 million users in Europe and suddenly they're in a different legal category. What changes for them on day one?
Mimi
Technically, a lot. They have to do formal risk assessments now—not internal audits they keep to themselves, but documented evaluations of how their platforms could enable illegal content, harm minors, or damage mental health. And they have to show they're taking steps to mitigate those risks.
Luke
But do we know what "mitigation" actually means in practice? The DSA says they have to do it, but the specifics of how each platform implements that—that's still being worked out in real time.
Mimi
Right. The Commission has enforcement power, but we're in the early phase of how this plays out. ChatGPT is the first AI chatbot in this category, so there's no precedent for what compliance looks like for a generative AI system.
Mark
And ChatGPT is also under the EU's AI regulations separately, correct?
Mimi
Yes. It's operating under two regulatory frameworks at once. The DSA treats it like any other large platform. The AI Act treats it as an AI system with its own set of requirements.
Luke
Which raises a question: if ChatGPT violates the DSA, who enforces it? If it violates the AI Act, who enforces that? Are those the same regulators, or is there overlap and potential confusion?
Mimi
That's still being clarified. The Commission oversees both, but the mechanics of enforcement and how they coordinate—that's part of what we'll learn as these cases actually develop.
Mark
The article mentions TikTok being told to change its addictive design or face a ban. Is that a DSA enforcement action, or something separate?
Luke
That's a separate threat, actually. It's the Commission using its broader authority to pressure a platform on a specific design practice. The DSA gives them tools, but that particular ultimatum is more about the Commission's willingness to use its power to regulate how platforms are built.
Mimi
And it signals something important: the EU isn't just regulating after harm occurs. They're trying to regulate the design itself—the features that keep people engaged, the algorithms that decide what you see. That's a different kind of regulatory ambition than most countries have attempted.
Le Pouls
- Three of America's most widely used digital platforms have crossed a legal tripwire in Europe, triggering compliance obligations that carry real enforcement consequences.
- ChatGPT's designation is a watershed — no AI chatbot has ever been subject to the DSA before, and it now faces dual regulation under both platform and AI-specific frameworks.
- Roblox and Reddit, platforms beloved by younger and community-driven audiences, must now formally audit their own potential to cause harm — from illegal content to psychological damage.
- The EU is not waiting for harm to materialize: the DSA demands proactive risk mapping and mitigation, a fundamentally different posture than reactive prosecution.
- Brussels has already signaled its willingness to escalate, warning TikTok that addictive design features could result in a bloc-wide ban — a precedent that now looms over every newly designated platform.
In a move that reflects Europe's deepening conviction that digital power must be met with democratic accountability, the European Commission has formally designated ChatGPT, Reddit, and Roblox as Very Large Online Platforms under the Digital Services Act — a threshold crossed when each surpassed 45 million monthly users within the EU. The designation is not ceremonial: it imposes binding obligations to assess and reduce harms related to illegal content, child safety, and mental health. ChatGPT's inclusion is particularly notable, marking the first time an AI chatbot has been drawn into this regulatory orbit, even as it simultaneously faces scrutiny under the EU's separate AI framework.
The European Commission moved Monday to place ChatGPT, Reddit, and Roblox under the stricter tier of its Digital Services Act, after each platform exceeded 45 million average monthly users in the EU. The designation as Very Large Online Platforms carries binding legal weight: the three companies must now formally assess risks — including illegal content, threats to child safety, and impacts on mental health — and implement systems to mitigate them before harm occurs.
ChatGPT's inclusion is a landmark. The OpenAI chatbot becomes the first AI system of its kind to fall under the DSA, and it faces an additional layer of scrutiny under the EU's separate AI regulations — meaning it must now navigate two distinct regulatory frameworks simultaneously. Roblox and Reddit, meanwhile, join TikTok and Meta in a regulatory tier that has already been reshaping how large platforms operate across the bloc.
The expansion of the VLOP list reflects a Commission that is actively watching platform growth and applying the law as services cross the threshold. The DSA's logic is proactive rather than punitive: rather than waiting for specific harms to emerge, it requires platforms to identify and reduce systemic risks in advance. For ChatGPT, Reddit, and Roblox, the compliance clock has now started. And with Brussels having already warned TikTok that addictive design features could result in a ban across all member states, the message to newly designated platforms is clear — this regulator intends to follow through.
The European Commission moved Monday to bring three major American technology platforms under stricter regulatory oversight. ChatGPT, Reddit, and Roblox have each crossed a threshold of 45 million average monthly users within the European Union, triggering obligations under the Digital Services Act that took effect across the bloc in February.
The designation as Very Large Online Platforms, or VLOPs, means the three companies must now conduct formal assessments of potential harms and put systems in place to mitigate them. The risks they are required to address include the spread of illegal content, threats to child safety, and impacts on user mental health. This is not a suggestion or a best practice recommendation—it is a legal requirement, with compliance obligations that carry enforcement weight.
ChatGPT's inclusion marks a significant moment in the regulation of artificial intelligence. The OpenAI-owned chatbot is the first AI system of its kind to fall under the DSA's jurisdiction. It also faces a parallel layer of scrutiny under the EU's separate artificial intelligence regulations, making it subject to two distinct regulatory frameworks simultaneously. The dual oversight reflects the bloc's determination to manage both the general platform risks that apply to any large online service and the specific risks that AI systems present.
Roblox, a platform built around user-generated gaming content, and Reddit, the discussion forum site, join ChatGPT in the VLOP category. They are now in the same regulatory tier as TikTok and Meta, companies that have already been operating under DSA requirements for months. The expansion of the list signals that the Commission is actively monitoring platform growth and will continue to apply the law as services cross the user threshold.
The European Union's approach to tech regulation has hardened noticeably in recent years. Beyond the DSA framework, the Commission has taken direct action against individual platforms over specific practices. TikTok, for instance, has been told explicitly that it must redesign features the EU views as deliberately addictive or face the possibility of a ban across all member states. That threat—not a hypothetical but a stated consequence—underscores how seriously Brussels now treats the question of platform design and its effects on users.
The DSA itself represents a fundamental shift in how the EU regulates digital services. Rather than waiting for specific harms to occur and then prosecuting them, the law requires large platforms to be proactive: to identify risks in their systems, to measure their prevalence, and to take steps to reduce them before they cause damage. For ChatGPT, Reddit, and Roblox, that means the compliance work begins now. They have obligations to meet, assessments to conduct, and mitigation measures to implement—all under the watchful eye of a regulator that has shown it is willing to follow through on enforcement.
