OpenAI earned $10 billion in a single quarter, yet still finds itself playing catch-up in the AI race. The Information exclusively revealed that OpenAI’s revenue for the third quarter of 2026 reached approximately $10 billion, surging nearly 50% quarter-over-quarter and nearly tripling year-over-year—marking its first quarter surpassing the $10 billion threshold. Bloomberg subsequently confirmed this figure. This growth was primarily driven by increased demand for APIs from new models like GPT-5.6 and Astra, enterprise product sales, and the expansion of ChatGPT’s advertising business. However, Anthropic generated approximately $17 billion in revenue during the same period, still leading OpenAI by about $7 billion. That said, the two companies have historically used different revenue reporting methodologies, making direct comparisons imperfect. Interestingly, their growth trajectories are shifting. OpenAI’s revenue growth slowed to just 17% last quarter but has now accelerated back to nearly 50% this quarter; Anthropic, by contrast, saw its quarter-over-quarter growth decline from over 140% in Q2 to approximately 47% in Q3. This reflects a competition between two distinct commercialization strategies. Anthropic has deeply embedded its products—like Claude Code—into enterprise workflows, while OpenAI is attempting to capture multiple markets simultaneously: developer APIs, enterprise agents, consumer subscriptions, and advertising. Previously, the debate centered on which model was smarter. Now, capital markets are increasingly focused on one question: who can effectively convert model capabilities into sustained revenue while maintaining profitability amid massive compute costs? The number-one model on the leaderboard may change every month—but real competitive moats are proven by customers who consistently pay.
