OpenAI Multicloud Pivot Accelerates

Microsoft announced it will stop revenue‑sharing with OpenAI and described the partnership as non‑exclusive; OpenAI has since broadened cloud relationships (including with Amazon) to meet growing compute needs. The commercial restructuring — plus Microsoft’s 27% stake — signals a move away from single‑vendor dominance toward multicloud sourcing and more transactional partnerships. — If AI providers increasingly spread workloads across multiple cloud vendors, that will reshape market power, antitrust exposures, supply‑chain resilience, and government leverage over critical AI infrastructure.
