EU Places ChatGPT and Reddit Under Strictest Digital Services Act Oversight

The European Union has designated ChatGPT and Reddit as high-impact digital services, subjecting them to the most stringent regulatory requirements under the Digital Services Act (DSA). This move signals a tightening of oversight for generative AI and community-driven platforms operating within the bloc.

According to the European Commission, Reddit has been classified as a Very Large Online Platform (VLOP), while OpenAI's ChatGPT has been designated as a Very Large Online Search Engine (VLOSE). These designations are triggered when a service exceeds 45 million monthly active users in the EU. Along with these two, Roblox has also been designated under the DSA framework. As a result, these companies must now implement rigorous systemic risk assessments and publish detailed transparency reports regarding their content moderation and algorithmic processes.

The DSA Framework

The Digital Services Act serves as the EU's comprehensive regulatory framework for online intermediaries. By categorizing services as VLOPs or VLOSEs, the EU applies a tiered system of responsibility where the largest players bear the heaviest burden of proof regarding safety. The goal is to mitigate systemic risks—such as the spread of illegal content or the manipulation of public discourse—by forcing platforms to be transparent about how their algorithms function and how they police their users.

Industry Implications

This regulatory shift is significant because it forces a fundamental change in how AI and forum-based platforms manage data and moderation in Europe. For OpenAI, the VLOSE designation acknowledges the role of ChatGPT as an information retrieval tool, bringing it under the same scrutiny as traditional search engines. For Reddit, it means a transition from a loosely moderated community forum to a highly regulated entity with legal obligations to identify and mitigate systemic risks.

The financial stakes are substantial. Failure to comply with the DSA's strict obligations can result in massive penalties, with fines reaching up to 6% of a company's global annual turnover. This creates a powerful incentive for these firms to overhaul their internal compliance structures to meet European standards.

What to Watch

Observers will now be watching for the first round of mandatory transparency reports and risk mitigation plans from OpenAI and Reddit. The primary point of contention is likely to be the implementation of algorithmic transparency, as companies struggle to balance regulatory openness with the protection of proprietary trade secrets. It remains to be seen how the EU will enforce these rules against the unique architecture of generative AI compared to traditional social media platforms.
