Elon Musk is pursuing a multi-billion dollar legal battle against OpenAI and Microsoft, claiming that they reaped undue profits from his initial support for OpenAI. According to court documents, Musk's lawsuit, filed on Friday, argues for the restitution of 'wrongful gains' valued between $65.5 billion and $109.4 billion for OpenAI, and up to $25.1 billion for Microsoft.

The lawsuit has prompted strong responses from both companies, who refute Musk's claims. OpenAI dismisses the case as 'baseless' and a form of harassment, while Microsoft denies any involvement in aiding OpenAI's alleged missteps. Both companies filed a counter-claim challenging Musk's calculations of damages, terming them 'unsubstantiated' and potentially misleading.

The trial, expected to begin in April, underscores Musk's assertion that his early investment and involvement in OpenAI were pivotal. In his claim, Musk states he provided about $38 million, recruited staff, and connected founders with essential contacts. His legal team argues that OpenAI and Microsoft's financial gains far exceed his initial contributions.
