ChatGPT Reaches 1.2 Billion Weekly Users, Capturing 20% of Google's Search Volume

ChatGPT's acceleration to 1.2 billion weekly active users—with 200 million added in just two months—shows AI-assisted search has moved from early adopter to mainstream behavior. The 20% search volume parity with Google reflects a genuine shift in how consumers find information, particularly among younger demographics. OpenAI's growth rate suggests the consumer AI market is consolidating around a few dominant players. The meaningful competition is no longer between ChatGPT and search engines, but between OpenAI and other LLM providers for the infrastructure layer that shapes how people access and trust information.
