Musk v. Altman Evidence Shows What Microsoft Executives Thought of OpenAI

Court filings in the ongoing Musk v. Altman lawsuit have surfaced internal Microsoft communications from 2018 that reveal how senior leaders at the tech giant privately viewed OpenAI during the early years of their deepening partnership. According to documents reviewed by Wired, Microsoft executives expressed significant skepticism about OpenAI's commercial prospects and technical direction, even as the company moved forward with what would become a multibillion-dollar investment.

The emails suggest that despite public enthusiasm for the collaboration, decision-makers at Microsoft were unconvinced that OpenAI could deliver on its ambitious artificial intelligence research goals within a realistic timeframe. Internal discussions referenced concerns over the startup's talent retention, its reliance on Microsoft's Azure cloud infrastructure for compute, and the credibility of its leadership at the time.

Perhaps most revealing is the strategic calculus behind Microsoft's continued engagement. Executives feared that withdrawing support or applying too much pressure could push OpenAI directly into a competing cloud deal with Amazon Web Services, giving a rival hyperscaler both a high-profile AI partner and deeper influence over the emerging generative AI landscape. That risk calculus appears to have shaped Microsoft's posture as it deepened financial commitments to OpenAI, including the massive funding round announced in 2023.

The disclosures add another layer of complexity to Elon Musk's lawsuit against OpenAI and its CEO Sam Altman, which alleges that the organization strayed from its original nonprofit mission. For Microsoft, the emails underscore how the company's investment in OpenAI was as much about neutralizing a potential competitor as it was about advancing frontier AI research, a dynamic likely to draw scrutiny from regulators and courts as the case moves forward.
