Amazon is investing $50B into OpenAI. Crucially, OpenAI will use AWS "Trainium" chips for workloads, which Jassy claims offer "30-40% better price performance." This is not just a cash injection; it is a customer acquisition strategy. By forcing the world's largest AI model (OpenAI) onto Amazon's custom silicon (Trainium), Amazon reduces dependency on Nvidia and validates its own hardware stack. LONG. This creates a flywheel of AWS revenue and validates their $200B Capex spend. If OpenAI fails to deliver AGI or revenue growth slows, the $50B investment becomes dead capital.
