Who's using ChatGPT? Numbers and demographics
ChatGPT isn't just for techies. Its users range from students to big companies and even government teams.
The US leads with 19% of all users, followed by India (7%) and Brazil (5%).
It's especially popular with software developers (79% use it) and millennials (34%).
Fun fact: nearly all Fortune 100 companies use ChatGPT, plus about a quarter of US adults and most college students.
OpenAI's growth story in numbers
OpenAI pulled in $3.7 billion revenue last year, and by mid-2025 hit $10 billion in annual recurring revenue.
At their recent Dev Day event, they launched new tools for building smarter AI apps.
Despite its nonprofit roots, OpenAI is now valued at $500 billion after a massive funding round—making it the world's most valuable private company right now.
