Microsoft CorporationEisman warns Microsoft's OpenAI-linked Azure revenue (70% of hyperscaler AI revenue from OpenAI/Anthropic) could become uncollectable if OpenAI can't pay its $250B Azure commitment.
Steve Eisman, the money manager who shorted subprime and was portrayed by Steve Carell in The Big Short, warned on his September 21 podcast that 70% of hyperscaler AI revenue comes from just OpenAI and Anthropic, amounting to roughly 25% to 35% of the hyperscalers' entire cloud revenue, and said the entire ecosystem depends on two companies, with OpenAI the one he thinks is in trouble. The warning came six days after OpenAI CFO Sarah Friar told CNBC on September 15 that the company's business is a diversified set of revenue streams with strong margins and a diversified chip supply chain, and a day before CNBC reported investors had approached OpenAI about a new funding round at a valuation as high as $1.5 trillion with no active raise underway. Eisman offered no source for the 70% figure. The concentration concern centers on Microsoft, whose market cap stands at $3.68 trillion and whose restructured OpenAI deal gave it a roughly 27% stake valued around $135 billion in exchange for OpenAI contracting $250 billion in incremental Azure services; if OpenAI cannot generate the cash to consume what it promised to buy, that remaining performance obligation becomes uncollectable. NVIDIA sits at the head of the chain with a market cap of roughly $5.52 trillion, fiscal Q2 revenue of $96.22 billion, up 105.8% year over year, data center revenue of $89.02 billion, and Q3 guidance of $108.0 billion. NVIDIA shares are up 23% year to date and 947.6% over five years, while Microsoft is up just 3.02% in 2026 and down 3.62% over the past year.

NVIDIA CorporationNVIDIA sits at the head of the AI chain whose demand hinges on OpenAI/Anthropic, but the article only cites its revenue and guidance without stating a clear impact.
Eisman says OpenAI is the company he thinks is in trouble, questioning its ability to generate cash for its commitments.
Anthropic is named as one of the two firms driving 70% of hyperscaler AI revenue, but no specific development about it is reported.
