What did the European Commission’s designation of ChatGPT, Reddit, and Roblox as “very large” online platforms or search engines under the Digital Services Act mean, why did each service receive its classification, what compliance obligations and January deadline now apply—includ

The designations place ChatGPT, Reddit, and Roblox in the DSA’s highest regulatory tier because each reported at least 45 million average monthly users in the EU. ChatGPT is classified as a Very Large Online Search Engine (VLOSE); Reddit and Roblox as Very Large Online Platforms (VLOPs). 678

What the designation means

• It does not declare the services unlawful or find that they have breached the DSA. It subjects them to the DSA’s additional, most stringent obligations for services whose systemic reach can affect society and democracy. 38
• The threshold is more than 45 million average monthly EU users—about 10% of the EU population—and the classifications follow the services’ own reported user figures. 678
• The deadline is four months after notification: the Commission’s announcement says compliance is due by the end of December 2026, not January. If “January” refers to the first full month of enforcement, the operative legal deadline is end-December 2026. 5

Why each service received its category

• ChatGPT — VLOSE: the Commission treats it as a very large online search engine, based on its reported EU user reach. 67
• Reddit — VLOP: it is designated as a very large online platform, based on reported EU reach and its platform role in hosting and distributing user content. 67
• Roblox — VLOP: it is likewise designated as a very large online platform, based on reported EU reach and its platform role in distributing user-created and interactive content. 67

Compliance obligations

The evidence provided establishes the broad point—extra DSA duties aimed at preventing abuse and managing systemic risks—but does not contain the full text of the Commission’s service-specific notice. The resulting requirements generally encompass:

• Assessing and mitigating systemic risks associated with illegal content and goods, effects on minors, fundamental rights, civic discourse and electoral processes, public security, and other societal harms. 3
• Maintaining mechanisms to identify, act on, and explain moderation decisions concerning illegal content, while providing greater transparency about content governance. 3
• Providing transparency concerning the operation and risks of their services, and taking risk-mitigation measures proportionate to identified systemic risks. 38

Insufficient evidence in the supplied material supports a more granular claim about the exact January date, precise service-by-service mitigation measures, audit timetable, recommender-system controls, advertising rules, or data-access duties.

Supervision and enforcement

• The Commission directly supervises designated VLOPs and VLOSEs under the DSA framework, rather than leaving their enhanced obligations solely to national authorities. 12
• The DSA can impose fines of up to 6% of a provider’s global annual turnover for infringements. However, the supplied evidence does not substantiate the asserted AliExpress, X, or Temu penalty amounts or outcomes, so those should not be treated as verified precedents here.
• The practical significance is therefore heightened regulatory scrutiny: these services must demonstrate compliance by the end of December 2026 and may face investigation and sanctions if they fail to meet their DSA obligations. 58
