On the up and up, and up: ChatGPT reaches 700M weekly users as AI adoption accelerates

ChatGPT is on track to reach 700 million weekly active users this week, representing a significant jump from 500 million at the end of March and a four-fold increase since last year. This milestone underscores the platform’s rapid mainstream adoption and positions OpenAI, the AI research company behind ChatGPT, as a dominant force in the consumer AI market, demonstrating sustained user engagement beyond initial curiosity.

What you should know: The user growth trajectory shows accelerating adoption rather than plateauing, with ChatGPT adding 200 million weekly users in just eight months.

• Weekly active users have grown from approximately 175 million a year ago to the current 700 million milestone.
• The platform continues expanding its use cases beyond casual interactions, with teams increasingly relying on it for complex problem-solving and creative work.

Why this matters: These numbers signal that AI tools have moved from experimental novelty to essential productivity infrastructure for millions of users worldwide.

• The sustained growth pattern suggests ChatGPT has achieved the kind of sticky user engagement that defines successful consumer platforms.
• Nick Turley, Head of ChatGPT at OpenAI, emphasized the platform’s mission-driven approach: “Every day, people and teams are learning, creating, and solving harder problems.”

The big picture: ChatGPT’s user base now rivals some of the world’s largest social media platforms, marking a watershed moment for AI adoption in mainstream workflows.

• The growth comes as OpenAI continues expanding ChatGPT’s capabilities and integrations across business and personal use cases.
• This milestone reinforces the company’s position ahead of major competitors like Google’s Bard and Anthropic’s Claude in the race for consumer AI dominance.
