ChatGPT reaches 1 billion monthly active users on its app, hitting the milestone in May, according to multiple outlets citing reporting from CNBC. The growth makes it the fastest application to reach that user scale, taking about three years to do so—significantly quicker than major consumer apps that previously required roughly five to eight years to reach similar adoption levels. The reports also note that public attitudes toward AI are becoming more mixed, with growing unease about ethical and environmental impacts. Despite this increased skepticism, ChatGPT’s user growth continues as other AI models and services expand and compete for users. Together, the sources describe both the scale of ChatGPT’s current adoption and the broader context of rapidly developing “AI economy” offerings that are increasingly drawing comparisons with other tech platforms’ growth trajectories.
