Microsoft is considering legal action over a $50 billion deal between Amazon and OpenAI

BlockBeats News, March 18th — According to the Financial Times, Microsoft is considering taking legal action regarding the $50 billion cloud collaboration deal between Amazon and OpenAI. At the core of this deal is OpenAI's enterprise AI Agent platform called Frontier, and Microsoft believes that running it on AWS may violate their API exclusivity agreement.

When Microsoft approved OpenAI's structural reorganization in October last year, relinquishing their exclusive cloud service provider status, they retained a key provision: all requests to access OpenAI models via API must be routed through Azure. To circumvent this restriction, Amazon and OpenAI developed a "Stateful Runtime Environment" (SRE) on Amazon Bedrock. The SRE can access enterprise data stored on AWS, enabling the Agent to have cross-tool memory and operational capabilities. Microsoft views this technical approach as unfeasible under the contract terms and, even if feasible, a violation of the agreement's spirit.

A source familiar with Microsoft's position stated, "We are clear on the contractual terms. If they breach it, we will sue. If Amazon and OpenAI are banking on their contract lawyers' creativity to prevail, I bet on our side." OpenAI, on the other hand, argues that Frontier is not primarily provided as an API, avoiding a red line, and believes that Microsoft is unlikely to actually litigate, given that Microsoft itself is facing antitrust scrutiny in the U.S., U.K., and the EU over its Azure licensing practices.

Prior to this, Business Insider exposed an internal Amazon memo that strictly defined the wording employees could use to describe SRE: they could say "powered by OpenAI" or "integrated with OpenAI," but were prohibited from saying "providing access to OpenAI models" or "invoking OpenAI models," and from implying that OpenAI's cutting-edge models were already available on AWS. Ahead of the Frontier launch, the three parties are still negotiating for a settlement. If the dispute ultimately escalates to court, it could impact OpenAI's planned IPO as early as this year.
