ChatGPT Weekly Users Near 1 Billion, Growth Slows Amid Competition

OpenAI's ChatGPT is closing in on a staggering 1 billion weekly active users, according to internal disclosures. The milestone, originally targeted for the end of last year, arrives seven months late—but still cements ChatGPT as one of the fastest-growing products in internet history, having launched less than four years ago. OpenAI declined to comment.

Why the delay?

The slowdown isn't a mystery. Google's Gemini has been steadily integrating with its billion-user search engine, siphoning traffic at the entry point. Meanwhile, GPT-5, released last autumn, faced a rocky development and widespread user criticism, dragging down growth. Anthropic's Claude has also carved out a slice of the market.

A shifting landscape

Hitting 1 billion users is no small feat, but the seven-month lag reveals a stark reality: ChatGPT's first-mover advantage is eroding. The AI chatbot market is no longer a one-horse race—it's a multi-player battlefield where every competitor is hungry for a share.

Key Points

  • ChatGPT weekly active users nearing 1 billion, seven months behind schedule.
  • Competition from Google Gemini and Anthropic Claude is eating into growth.
  • GPT-5's troubled launch contributed to the slowdown.
  • The AI chatbot market is becoming increasingly competitive.
