ChatGPT Has an Estimated 67.7 Million US Monthly Users, But Adoption Needs Context

ChatGPT had an estimated 67.7 million monthly active users in the United States , according to eMarketer market data. Separately, Pew Research Center found that 34% of US adults had ever used ChatGPT as of June 2025, up from 18% in July 2023. Both figures point to substantial public exposure to the service, but they should not be combined or treated as interchangeable measures of adoption. The difference matters for anyone using AI usage data to inform product, marketing, or internal technology decisions . Monthly active users indicate ongoing activity during a defined month. The share of adults who have ever used ChatGPT is a survey-based measure of cumulative experience, including people who may have tried it once and people who use it regularly. They answer different questions about the same technology. The two ChatGPT metrics measure different behavior The 67.7 million figure is an estimate , not a direct count published by ChatGPT. It comes from eMarketer's market forecasting data, available through its US ChatGPT users and penetration forecasts . Such estimates are useful for sizing current engagement, but the supplied research notes that the detailed methodology is typically available only to subscribers. Pew's 34% result has a different foundation. In its June 25, 2025 release, Pew surveyed US adults and asked whether they had ever used ChatGPT. The increase from 18% in July 2023 to 34% in June 2025 shows that reported familiarity expanded substantially over that period. It does not show how often respondents used the tool, whether they used it for work, or whether they continue to use it.
