The European Commission designated ChatGPT, Reddit, and Roblox as "very large online platforms" under its Digital Services Act, forcing them to remove illegal content and protect minors or face fines up to 6% of global revenue. All three services exceeded 45 million EU monthly users, triggering stricter regulatory requirements by year-end.

• ChatGPT joins X's Grok in facing DSA investigations, marking the EU's expanding enforcement of digital safety rules on AI services
• Companies must comply with obligations including illegal content removal and minor protection by December 31 or face substantial penalties
• The 45-million-user threshold automatically triggers enhanced scrutiny, meaning any platform crossing that mark in the EU becomes subject to these rules
