OpenAI Posts $10 Billion in Q3 Revenue as Enterprise Sales Top Half of Business

OpenAI generated $10 billion in revenue during the third quarter of 2026, about 50% more than in the prior quarter, Crypto Briefing reported, citing The Information on November 10, 2026. The San Francisco company builds and sells access to frontier AI models including GPT-5.6, Codex and Sora, and runs ChatGPT.

OpenAI's API and Enterprise Mix

Demand for OpenAI's application programming interfaces drove the quarter, with particular strength in newer models including GPT-5.6 and Astra. Advertising sales also added to revenue. Co-founder Greg Brockman said more than half of OpenAI's revenue now comes from enterprise clients.

Brockman said annualized revenue grew 70% quarter-over-quarter, a separate measure from the roughly 50% rise in quarterly revenue. On that basis OpenAI was running at around $50 billion at the end of September 2026, up from about $20 billion at the start of the year. The run rate is expected to push past $70 billion by year's end, with enterprise sales expected to carry much of that load.

Rival Anthropic announced nearly $17 billion in revenue for the same period, putting it ahead of OpenAI on quarterly revenue. Anthropic filed paperwork for its IPO, budgeting $41.5 million in legal fees, Business Insider reported.

Microsoft's OpenAI-Linked Revenue

According to akta.pro company records, OpenAI closed a $122 billion funding round in April 2026 and submitted a confidential draft S-1 to the SEC in June 2026, saying it had not decided on timing. The same records list a $20 billion Cerebras compute contract and a $99 billion CoreWeave backlog.

Microsoft said it generated $10 billion from commercial engagements tied to OpenAI in its fiscal quarter ending September 30, 2026, almost 11% of its $92.3 billion in quarterly revenue. Across fiscal 2026, Microsoft's revenue from OpenAI-linked activities reached $24.1 billion.

TSMC has not invested in OpenAI but will manufacture its custom AI inference chips, starting with the Jalapeño design on 3 nm, with mass production projected for 2026, Crypto Briefing also reported. Bishop Fox integrated OpenAI GPT Cyber Models into offensive security through the OpenAI Daybreak Defense Network, EIN Presswire reported.
