Microsoft's Total Investment in OpenAI to Exceed $100 Billion by June, CTO Reveals in Court

According to Beating and Microsoft CTO Kevin Scott's courtroom testimony on Wednesday, Microsoft's total investment in OpenAI will exceed $100 billion by June 2026, including infrastructure and AI computing costs. This figure significantly surpasses the previously disclosed $13 billion in direct cash investments. Kevin Scott confirmed that when the two companies built their first supercomputer years ago, they deployed over 10,000 GPUs in a single phase.

In related developments, the three-week discovery phase of Elon Musk's lawsuit against OpenAI concluded as Musk's legal team unexpectedly waived their right to file a rebuttal case after Microsoft and OpenAI completed their evidence presentation. The court will proceed directly to closing arguments on Thursday.
