Svmuu News On the last day of the discovery phase in Musk's lawsuit against OpenAI, a Microsoft executive revealed in court that by June 2026, Microsoft's total investment in OpenAI (including investment commitments, infrastructure, and computing power hosting costs) will exceed $100 billion.
The report states that this figure is significantly higher than the market's general understanding of a $13 billion cash investment, marking the first disclosure of Microsoft's overall costs in supporting OpenAI through underlying computing power and infrastructure. Microsoft CTO Kevin Scott also confirmed that when the two parties first built the initial supercomputer, they deployed tens of thousands of GPUs at once.
Furthermore, after Microsoft and OpenAI concluded their presentation of evidence, Musk's team chose to forgo the rebuttal phase, officially ending the three-week discovery period. The court is expected to enter the closing argument phase on Thursday.
