ChatGPT Hits 1 Billion Users While AI Adoption Accelerates Amid Growing Public Skepticism

Public backlash against AI has become more visible and institutional: one report highlights that “college graduates jeering mentions of artificial intelligence at commencement speeches,” alongside warnings “as disparate as the Pope and technology giant Anthropic,” reflect a broader “sobered” sentiment even as AI usage rises.
OpenAI’s internal positioning of ChatGPT’s scale went beyond user counts: OpenAI “claimed it had more than six times the monthly web visits and mobile sessions of the next largest AI platform,” according to the article citing Reuters, while also noting OpenAI did not respond to CNBC’s comment request.
Competitive metrics included absolute MAU figures, not just growth rates: Reuters (via the summary site) reported Claude had “56 million global monthly active app users in the second quarter to date,” alongside its ~640% year-over-year MAU increase.
Reuters also described early cross-usage effects between rivals: in the U.S., users who installed Anthropic’s Claude in Q1 spent about “5% less time on ChatGPT one month after installation,” signaling measurable (if limited) switching behavior after new installs.
ChatGPT hit 1 billion monthly active users in May 2026, becoming the fastest app in history to reach that milestone — doing it in roughly 3.5 years, faster than Google Maps (5 years), TikTok (about 4 years), and Facebook (4.5 years), according to Sensor Tower data reported by Reuters and CNBC.
The news lands in a strange moment for AI. Usage is surging. But so is public unease. A March 2026 Pew Research survey found 50% of U.S. adults felt more concerned than excited about AI. And this spring, college graduates booed pro-AI speeches at multiple commencement ceremonies across the country.
ChatGPT launched on November 30, 2022, and hit 1 million users in just five days. By January 2023, it had 100 million monthly users — already the fastest consumer app on record at the time, according to Reuters. It kept growing. By February 2026, OpenAI reported 900 million weekly active users and 50 million paying subscribers, according to TechCrunch.
OpenAI also claimed ChatGPT had "more than six times the monthly web visits and mobile sessions of the next largest AI platform," according to CNBC. The company did not respond to a comment request about the 1 billion milestone. OpenAI's annualized revenue hit $25 billion by February 2026, according to reporting cited by Seeking Alpha.
ChatGPT's dominance is real, but competitors are closing ground fast. Anthropic's Claude grew about 640% year over year in monthly active users, reaching 56 million global monthly app users in Q2 2026, according to Reuters. Meta AI grew even faster — up about 973% year over year — as Meta pushed its assistant across Facebook, Instagram, and WhatsApp.
There are early signs of switching behavior too. U.S. users who installed Claude in Q1 2026 spent 5% less time on ChatGPT one month after installation, according to Reuters. That's a small dent. But Sensor Tower analyst Abraham Yousef noted that "negative sentiment is undeniably growing" even as "consumers are increasingly using and relying on these platforms," according to Seeking Alpha.
The backlash is coming from many directions at once. In May 2026, Pope Leo XIV signed a 40,000-word encyclical called Magnifica Humanitas, warning that AI risks "replacing workers, accelerating war, and exploiting the environment," according to AP. He released it alongside Anthropic co-founder Christopher Olah — a pairing some critics called "Vatican-washing," according to The Guardian.
That same month, Meta laid off about 8,000 employees — 10% of its workforce — and explicitly cited AI-first operations as the reason, according to Reuters. Meanwhile, graduates at the University of Arizona, Middle Tennessee State University, and the University of Central Florida all booed pro-AI speakers at commencement ceremonies. Pew found 57% of U.S. adults rate AI's societal risks as "high."
The clearest takeaway from the data is a widening gap. People are worried about AI. They're also using it more than ever. About 40% of regular ChatGPT users report saving a full workday each week, according to research cited by CNBC. Adoption has grown especially among people over 35, and across more geographic groups than before.
A price war is now underway. Google cut its entry-level AI subscription from $7.99 to $4.99 in June 2026, and OpenAI is weighing similar reductions, according to PYMNTS. With both OpenAI and Anthropic reportedly filing confidential IPO documents in June, according to Fortune, the race for users — and revenue — is only getting more intense.
