Tensions between OpenAI and Microsoft (NASDAQ: MSFT) are rising fast — and behind the scenes, discussions have turned combative.

According to the Wall Street Journal, OpenAI executives have recently debated a dramatic move: filing antitrust complaints against Microsoft if the tech giant doesn’t ease its grip over the partnership.

At the heart of the conflict is OpenAI’s push to gain independence over its AI products and infrastructure, and to receive Microsoft’s greenlight to formally convert into a for-profit entity — a necessary step if OpenAI wants to raise more money and eventually go public.

Microsoft’s approval is mandatory under the terms of their contract — giving it significant leverage.

From partners to competitors

The six-year relationship between the two companies, once hailed as a model tech partnership, is now under intense strain. While Microsoft has invested billions into OpenAI in exchange for early access to its models (including GPT-4), the companies are increasingly stepping on each other’s turf — both racing to commercialize AI at scale.

OpenAI, for example, launched ChatGPT Team and Enterprise, while Microsoft embedded GPT models into Copilot across Windows and Office — turning them into rivals for AI productivity tools.

Sources familiar with the talks say negotiations around future terms have grown increasingly difficult. OpenAI is now considering a “nuclear option” — launching a formal antitrust review and pressuring Microsoft through public messaging.

What’s at stake?

An antitrust challenge could fracture one of the most influential collaborations in the tech sector. Microsoft has relied heavily on OpenAI’s models to fuel its $3 trillion valuation narrative, while OpenAI has depended on Microsoft for cloud compute via Azure and enterprise-scale distribution.

A regulatory dispute could also attract broader scrutiny around vertical integration in AI, as more startups and regulators question the role of hyperscalers like Microsoft, Amazon, and Google in locking up the AI stack.

The AI boom’s most iconic partnership may soon become its most public divorce — with OpenAI threatening to bring regulators into the room if Microsoft doesn’t back off.
