Billionaire entrepreneur Elon Musk has lost his lawsuit against OpenAI and its leadership after a U.S. jury ruled against his claims in a California federal court.

The case centred on allegations that OpenAI had deviated from its original nonprofit mission of developing artificial intelligence for the benefit of humanity.

Musk accused OpenAI CEO Sam Altman, its executives, and partners of shifting the organisation toward a profit-driven model and moving away from its founding principles.

He also challenged OpenAI’s commercial partnerships and corporate structure, arguing that they conflicted with its original mission.

However, jurors in Oakland unanimously found that Musk filed the lawsuit outside the permitted legal time limits, bringing the case to an end after less than two hours of deliberation.

Musk’s legal team has indicated that it may appeal the decision.

The ruling represents a significant legal victory for OpenAI amid growing scrutiny over the governance and future direction of major AI companies.
