OpenAI is planting a flag in São Paulo, launching commercial operations in a country that has quietly become one of its most engaged markets. Brazil now ranks among ChatGPT’s three largest markets by weekly active users, with usage nearly doubling over the past year. Brazilians send approximately 215 million messages to ChatGPT every day — a scale that makes the country impossible to ignore for any AI company serious about global reach.

What’s striking is not just the volume but the shift in how Brazilians are using the tool. By June 2026, 35% of classified messages from individual ChatGPT accounts in Brazil were work-related, compared with 30% globally. Of those, 53% asked ChatGPT to actually complete a task or produce output — drafting proposals, analyzing information, writing code. That’s a meaningful gap above the global average, suggesting Brazilian users are moving from experimentation to practical application faster than most. OpenAI funded an independent RegLab study estimating AI could add nearly R$1 trillion to Brazil’s economy by 2030, a figure that gives the commercial push a clear economic narrative.

Brazil’s developer ecosystem tells a similar story. The country ranks second globally by number of developers using the OpenAI API and is Codex’s largest market in Latin America. Since the start of 2026, weekly Codex users in Brazil have grown more than elevenfold, with daily interactions up nearly thirtyfold. Enterprise adoption is climbing too — ChatGPT Enterprise seats increased fivefold year over year, putting Brazil among OpenAI’s ten largest markets by business customers. The company is pairing its commercial push with partnerships: ChatGPT Edu accounts at Instituto Tecnológico de Aeronáutica, research grants for IMPA and Hospital das Clínicas, an AI literacy program with legal-sector unicorn ENTER, and small-business support through Estímulo.

The local team’s stated mission is to help Brazilian organizations find valuable use cases, prepare their workforce, and establish responsible governance. That’s the right framing, because raw adoption numbers alone won’t guarantee the R$1 trillion projection materializes. The real test for OpenAI in Brazil — and for Brazil in AI — will be whether the enthusiasm of individual users and developers translates into durable institutional value, not just impressive engagement metrics. The groundwork is clearly there. Whether it compounds depends on execution that neither OpenAI nor its Brazilian partners have fully demonstrated yet.
