Elon Musk Sues OpenAI and Microsoft for $134 Billion

Elon Musk is seeking more than $134 billion from OpenAI and Microsoft, alleging that the two companies reaped “undue profits” from his initial support. According to the lawsuit, OpenAI earned between $65.5 and $109.4 billion, while Microsoft earned between $13.3 and $25.1 billion, thanks to Musk’s contributions since 2015. The lawsuit argues that OpenAI, originally a non-profit, changed direction and is pursuing profits, violating the agreement with Musk.
