Elon Musk dropped a bombshell Friday, demanding up to $134 billion from OpenAI and Microsoft for “wrongful gains” tied to his early backing of the AI pioneer. 

The Tesla tycoon claims his $38 million 60% of OpenAI’s seed funding in 2015 fueled explosive growth now valued at $500 billion, with OpenAI pocketing $65.5-109.4 billion and Microsoft grabbing $13.3-25.1 billion in benefits.

Early Days Boost

Musk didn’t just cut checks; he recruited talent, forged key connections, and lent star power to OpenAI’s nonprofit launch. 

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. MSFT shares closed at $459.86 on Jan 16, up 0.7%, shrugging off the news amid a $3.8T market cap.

Legal Firefight Ahead

The South African billionaire’s legal team sought expert advice from financial economist C. Paul Wazzan.  He stated that Musk provided OpenAI with $38 million in early funding as well as key industry contacts and expertise.

Based on those contributions, Wazzan believes Musk is entitled to a portion of OpenAI’s current value, which is estimated to be between $65.5 billion and $109.43 billion.

What Lies Ahead

This courtroom clash pits AI’s open ideals against profit motives, potentially reshaping founder rights in tech’s boom sector. Musk’s xAI rivalry fuels the fight over generative AI control as OpenAI pushes for-profit shifts amid Grok competition.

An April jury could disrupt Microsoft-OpenAI ties, sparking more early-backer suits and venture caution. Settlement talks may intensify pre-trial, but prolonged battles risk innovation focus. Investors facing volatility outcomes could empower agile rivals over giants.
