Oracle could become a vulnerable point in the artificial-intelligence infrastructure boom if OpenAI encounters financial difficulties, Council on Foreign Relations senior fellow Sebastian Mallaby said. S&P Global cut Oracle’s rating to BBB- on July 9, one notch above junk, and estimated that roughly half of its $638 billion in contracted future revenue is linked to OpenAI. Oracle expects $90 billion to $95 billion in fiscal 2027 capital expenditure and plans to raise another $20 billion through an equity offering this year. OpenAI has agreed to purchase roughly $300 billion of Oracle computing capacity over five years starting in 2027, or about $60 billion annually, exceeding its current reported annualized revenue of around $40 billion. OpenAI CEO Sam Altman said he expects to use the company’s planned compute capacity profitably but warned that parts of the wider buildout show "unsustainable silliness," particularly among neocloud operators without sufficient revenue or committed buyers. Customers are prepaying or supplying hardware for $75 billion of Oracle’s largest AI contracts, and Oracle’s cloud infrastructure revenue grew 77% in fiscal 2026, while companies including CoreWeave and Nebius have long-term contracted revenue and Bitcoin miners such as IREN, Hut 8, Bitdeer and Cipher Mining are investing in GPU campuses.
