Oracle's Massive AI Capex Fuels Market Worries and Triggers Microsoft Stock Dip

Oracle reported record fourth‑quarter FY2026 results, with total revenue of $19.2 billion, cloud revenue up 47% and Oracle Cloud Infrastructure (OCI) revenue soaring 93% to $5.8 billion. The company disclosed a $670 billion backlog of AI infrastructure contracts and a remaining performance obligation of $6.38 trillion. It also forecast AI‑related capital spending of about $70 billion for FY2027, to be financed partly by new debt and equity issuance. Analysts said the scale of spending exceeds Oracle’s free cash flow, raising concerns that AI capital outlays may be difficult to recover.

The market reaction spilled over to other major software firms. Microsoft’s shares fell more than 6% after the Oracle earnings highlighted the broader risk of heavy AI investment, while Microsoft announced a new in‑house foundational model aimed at reducing dependence on OpenAI and controlling AI costs. The episode underscores heightened investor sensitivity to the financial sustainability of the current AI infrastructure boom.
