Musk Sues OpenAI, Microsoft for $134 Billion
Elon Musk is suing OpenAI and Microsoft for up to $134 billion.
He says OpenAI promised to be a charity but became a for-profit company with Microsoft's help.
Musk gave OpenAI $38 million when it started, and now he wants a share of its $500 billion value.
OpenAI says Musk's lawsuit is not true and is just trying to bother them.
A judge said the case can go to trial in late April.
OpenAI is now partly owned by Microsoft, but its nonprofit part is still in control.
Musk also tried to buy OpenAI for $97.4 billion, but OpenAI said no.
Elon Musk is suing OpenAI and Microsoft for up to $134 billion in damages.
Musk claims OpenAI abandoned its nonprofit roots and defrauded him by taking Microsoft's investment.
A judge rejected OpenAI and Microsoft's request to dismiss the case, setting a trial for late April 2026.
OpenAI says Musk's lawsuit is baseless and part of his ongoing harassment.
OpenAI recently restructured, giving Microsoft a 27% stake while keeping its nonprofit arm in control.
