News: Microsoft Disclosures Suggest OpenAI Sales Account For Around 70% Of FY26 AI Revenue, more than 7% of FY26 Revenue

Summary

Ed Zitron reads Microsoft’s FY26 disclosures as showing OpenAI generated about $24.1B in revenue for Microsoft — roughly 70% of Microsoft’s AI revenue and over 7% of total company revenue — largely via Azure compute purchases. His argument: against roughly $270B in Microsoft capex, that revenue is heavily concentrated in a single client (OpenAI) rather than diversified enterprise AI adoption, which he takes as further evidence for the AI-spending-bubble thesis rather than a broad-based AI business.

Implications

Directly on the cost/economy of AI thread, and it’s the bear-case companion to the Google momentum memo enriched alongside it — one lab claims broad “full stack” traction, this piece argues the industry’s actual revenue is concentrated and circular (Microsoft spends on infrastructure that mostly serves one customer who is itself burning cash). Corroborates the thread’s running Zitron citations (his “AI Demand Bubble” essay, the $110B TTM-revenue-vs-$122B-raised gap) — this is fresh, dated financial-disclosure evidence rather than commentary, which raises its weight as a falsifiable data point for the bubble/no-bubble debate the thread has been tracking without resolution.
