This OpenAI analysis reveals that roughly 4 million people in the US used ChatGPT during March 2026 to help start, run, or grow a small business—and they’re not tech founders. These are owners of consulting practices, online stores, home-service companies, beauty salons, and restaurants. For them, AI isn’t a product to sell; it’s a flexible assistant that tackles tasks once requiring a whole team or outside consultants. The report found 71% of entrepreneurial users were already running a business, with the biggest groups in professional services (22%), retail (21%), and home trades (12%). They use AI for marketing, customer communication, legal queries, and more—reducing administrative burdens that eat up owner time. Active entrepreneurs also tend to be heavier users: 78% of them are on paid plans versus 67% on free. Why it matters: This signals a shift where AI becomes an affordable first line of support, leveling the playing field for small businesses against larger competitors who have dedicated staff.
