Amazon begins offering OpenAI products on AWS one day after Microsoft exclusivity ends

Within one day of Microsoft's exclusivity agreement with OpenAI expiring, Amazon began offering OpenAI models through AWS Bedrock. This marks a tectonic shift in cloud AI distribution — for years, enterprises wanting OpenAI through the cloud had to use Azure. Now the models are available on the platform where most enterprises already run their infrastructure, fundamentally changing competitive dynamics in cloud AI.

Why post about this

The speed is the story — exclusivity ends Monday, OpenAI is on AWS Tuesday. This reshuffles the cloud AI competitive landscape overnight. Enterprises that were locked into Azure for OpenAI access now have a real choice. Developer and business audiences both need to understand what this means for their stack decisions and the broader power dynamics in cloud computing.

Suggested angle

Lead with the speed to establish stakes, then explain what it means practically: most enterprises already run on AWS, so this removes the biggest reason many were considering Azure. Frame it as the moment cloud AI became truly competitive.

Expert consensus

Cloud analysts view this as a significant competitive blow to Azure's AI differentiation. Enterprise architects welcome multi-cloud optionality. Some question whether this signals OpenAI pulling away from Microsoft's orbit.
