Musk seeks up to $134B from OpenAI and Microsoft, escalating AI “mission drift” lawsuit

Elon Musk is asking a federal court for up to $134B in damages from OpenAI and $MSFT, arguing they earned “wrongful gains” tied to his early support of OpenAI. The dispute centers on claims that OpenAI abandoned its original nonprofit mission as it evolved into a highly commercial, for-profit structure. A jury trial is scheduled for April 2026 in Oakland, California.

Why markets care

This is a governance-and-control headline for AI: who owns the upside, what “mission” promises mean, and how much legal risk sits on top of the AI monetisation story. Even if the case takes months, the overhang can influence valuations, partner negotiations, and how quickly big AI buildouts get signed.
