## Microsoft Executive Testifies Company Has Invested Over $100 Billion in OpenAI Partnership
A Microsoft executive told a court that the company has invested more than $100 billion in its partnership with OpenAI, a figure that dramatically illustrates the financial depth of a relationship now at the center of Elon Musk's lawsuit against OpenAI and CEO Sam Altman. Michael Wetter, a Microsoft vice president, provided the testimony during proceedings where Musk alleges OpenAI abandoned its nonprofit mission in favor of commercial interests aligned with Microsoft. The disclosure marks the first time a specific cumulative total has been articulated under oath in connection with the case.

The amount encompasses Microsoft's original investments as well as ongoing capital commitments flowing into OpenAI's operations, infrastructure, and research. The figure dwarfs earlier public estimates and positions the partnership as one of the largest technology-sector investments in recent history. Microsoft's stake has given it significant influence over OpenAI's direction, including preferential access to the startup's models and computing infrastructure built largely on Azure. The relationship has drawn regulatory scrutiny in the United States and Europe over questions of market concentration and whether the arrangement effectively constitutes an acquisition that should have triggered merger reviews.

Musk's legal team has pointed to the investment scale as evidence that OpenAI's governance structure is structured to benefit Microsoft at the expense of the organization's founding commitments to develop artificial general intelligence safely and openly. OpenAI has denied the allegations, arguing its hybrid model is necessary to fund the compute-intensive work required to advance AI safely. The testimony is expected to feature prominently as the case moves forward, with both sides likely to use the financial relationship to support competing narratives about OpenAI's purpose and accountability.
