About
OpenAI is a frontier AI research and deployment company founded in December 2015 as a nonprofit, with a for-profit arm created in 2019 and fully recapitalized in October 2025 under a public benefit corporation controlled by the OpenAI Foundation. The company builds large-scale language models (GPT-6 Astra, GPT-5.6 family, o-series reasoning, and the open-weight gpt-oss line) and distributes them through ChatGPT (900M+ weekly users and 50M+ paid subscribers), a developer API, and an enterprise suite spanning ChatGPT Enterprise/Business seats, the Codex coding agent, the Frontier agent-orchestration platform, and custom model work. OpenAI reported $13.07B booked revenue for 2025, reached a $40B+ revenue run rate by August 2026, filed a confidential S-1 in June 2026, and is widely expected to go public in 2027 or sooner.
The Take
OpenAI is the defining private company of the AI era — a hyper-growth business that closed the largest private funding round in history ($122B at $852B, March 2026) and reached a >$40B revenue run rate by August 2026, with enterprise revenue now overtaking consumer. But the gap between its commercial trajectory and financial reality is enormous: ~$21B of operating losses on $13.07B of booked 2025 revenue, a 20% capped revenue share to Microsoft through 2030, and a rival (Anthropic) that is now more valuable, growing faster in enterprise, and profitable before OpenAI. The bull case rests on GPT-6 Astra, Codex (5M+ weekly developers), and its in-house Jalapeño inference chip; the bear case on unfunded compute obligations, C-suite churn, and an IPO window that must price AI-scale losses for the first time.
