Why this drives traffic.
Musk argues OpenAI and its leaders abandoned a nonprofit, public-benefit mission while OpenAI argues Musk is using litigation to hurt a direct xAI competitor. The trial is one of the cleanest public records of how OpenAI changed from a donor-backed lab into a commercial AI power.

The questions jurors keep circling.
Did OpenAI's founding documents and representations create enforceable promises about nonprofit control and public benefit?
Did OpenAI's commercial structure preserve the mission, or invert it by making the nonprofit secondary to the for-profit business?
What did Musk know about OpenAI's for-profit plans, Microsoft relationship, and governance changes before suing?
Can a remedy benefit OpenAI's nonprofit arm without benefiting Musk, xAI, or a Musk-controlled fund?
How much of the dispute is about AI safety, and how much is about control of the most valuable AI company in the world?
