Musk Seeks Up to $134 Billion From OpenAI and Microsoft in Escalating Damages Fight

Defendants challenge his expert valuation as implausible, with a jury trial scheduled for April.

Overview

  • New court filings from Musk’s team outline demands of $65.5 billion to $109.4 billion from OpenAI and $13.3 billion to $25.1 billion from Microsoft.
  • The figures come from an expert who attributes Musk’s early $38 million funding plus contacts and know‑how to a share of OpenAI’s current value.
  • OpenAI and Microsoft moved to exclude the expert report, calling it invented and unverifiable in their request to the court.
  • A judge previously denied a motion to dismiss the lawsuit, clearing the case to proceed before a jury in April.
  • Musk alleges OpenAI abandoned its public‑benefit mission, while OpenAI argues he sought control of the lab and now operates rival xAI with its Grok chatbot.
