Elon Musk is seeking up ​to 134 billion dollars 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 dollars and 109.4 billion dollars from the billionaire ‌entrepreneur's contributions when he was co-founding OpenAI from ⁠2015, while Microsoft gained ‌between 13.3 billion dollars and 25.1 billion dollars, 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.

Musk's filing says he contributed about 38 million dollars, ⁠60 per cent of OpenAI's early seed funding, helped recruit staff, connect ‌the founders with key contacts and lend credibility to ‌the project when it was created.

"Just as an early investor in a startup company may realize gains many orders of magnitude greater than the ‍investor's initial investment, the wrongful gains that OpenAI and Microsoft have earned – and which Mr Musk is now entitled to disgorge – are much larger than Mr Musk's initial contributions," Musk argues.

The filing says Musk's contributions to OpenAI and Microsoft were calculated by his expert witness, financial economist C Paul Wazzan.

Musk may seek punitive damages and other penalties, including a possible injunction, if ​the jury finds either company ‌liable, the filing says, without specifying what form any injunction might take.
