Overview

  • Microsoft is considering suing OpenAI, according to the Financial Times, over plans to run the unreleased Frontier platform on Amazon Web Services in a deal reported at about $50 billion.
  • no lawsuit has been filed and the companies remain in talks, with a person familiar with Microsoft’s position quoted as saying it would sue if the contract is breached.
  • Microsoft contends a clause retained in a revised September agreement requires all API calls to OpenAI’s models to be routed through Azure, which it says the AWS plan would violate.
  • OpenAI and Amazon are developing a Stateful Runtime Environment on AWS Bedrock that would let agents access AWS data and maintain context across tasks, a setup Microsoft argues cannot be implemented without breaking the routing clause.
  • Sources say Microsoft may hesitate to litigate because regulators in the US, UK, and EU are already examining Azure licensing, and a court fight could also complicate OpenAI’s IPO plans; separately, Microsoft has reorganized its Copilot teams to address product fragmentation.
