Musk vs. OpenAI Trial Reveals Microsoft's $100 Billion Investment

The civil trial between Elon Musk and OpenAI reached a peak on Thursday, revealing financial details previously kept under tight wraps. Federal testimonies and documents presented in court confirm that Microsoft has allocated over $100 billion to the partnership, a figure nearly eight times the previously reported direct investment of $13 billion.

The True Cost of Azure Infrastructure

The $100 billion bill covers not just capital investments but also the massive cloud infrastructure costs on Azure and ongoing technical support to keep ChatGPT and other models running. This revelation places OpenAI in a nearly total dependence on Microsoft, supporting Musk's claims that the startup has turned into a "de facto subsidiary" of the Redmond giant.

In defense, Microsoft's CEO Satya Nadella argued that the costs reflect the scale of computing needed for AI's cutting edge but avoided detailing the profit margins Microsoft gains from these services.

Sam Altman's Parallel Fortune

Another critical point of the trial was the exposure of Sam Altman's personal investment portfolio. Court documents revealed that Altman holds over $2 billion in stakes across nine companies with direct commercial contracts with OpenAI. The biggest highlights are Helion Energy ($1.7 billion), Stripe ($633 million), and Retro Biosciences ($258 million).

Elon Musk uses this information to bolster accusations that Altman betrayed OpenAI's nonprofit mission for his own "side-deals." Musk is demanding in court the removal of Altman and Greg Brockman from leadership, along with the return of around $134 billion to the original foundation. With the conclusion of testimonies and closing arguments set for today, the verdict could force an unprecedented restructuring in the company valued at $852 billion.
