OpenAI has announced that ChatGPT has reached 500 million weekly active users, more than doubling from 200 million in early 2025 as AI assistants become embedded in daily life for hundreds of millions.

Growth Drivers

The surge is attributed to ChatGPT's integration into Apple Siri, Samsung devices, and enterprise workflows. GPT-5's multimodal capabilities have made the platform indispensable for professionals and students.

Revenue Milestone

OpenAI is now generating $15 billion in annualized revenue, split between consumer subscriptions and enterprise API contracts.
