AWS rents GPUs and its own Trainium chips and offers Bedrock model hosting; retail and ads are larger by revenue, so AI is concentrated in the AWS segment.

Microsoft monetizes AI through Azure AI infrastructure, Copilot subscriptions and model partnerships. Its 10-K calls its cloud and AI strategy a substantial investment that depends on customer demand.
