Musk seeks up to $134 billion from OpenAI, Microsoft in 'wrongful gains'

Elon Musk is seeking up to $134 billion from OpenAI and Microsoft, arguing he deserves the "wrongful gains" that they received from his early support of the artificial-intelligence startup, according to a court filing on Friday.



OpenAI gained between $65.5 billion and $109.4 billion from the billionaire entrepreneur's contributions when he was co-founding OpenAI from 2015, while Microsoft gained between $13.3 billion and $25.1 billion, Musk said in the federal court filing ahead of his trial against the two companies.



OpenAI, Microsoft and Musk's lawyers did not immediately respond to requests for comments outside business hours. OpenAI has called the lawsuit "baseless" and part of a "harassment" campaign by Musk. A Microsoft lawyer has said there is no evidence that the company "aided and abetted" OpenAI.



Musk, who left OpenAI in 2018 and now runs xAI with its competitor chatbot Grok, alleges that ChatGPT operator OpenAI violated its founding mission in a high-profile restructuring to a for-profit entity.



A judge in Oakland, California, ruled this month that a jury will hear the trial, expected to start in April.
