ChatGPT hits 1 billion monthly users faster than any app before it
One billion is the number apps spend years chasing and most never reach. ChatGPT got there faster than anything before it. OpenAI’s app crossed 1 billion global monthly active users in May, roughly three years after launch, according to estimates from Sensor Tower, making it the quickest app in history to the milestone.
