The claims have been narrowed to four causes of action. Judge Yvonne Gonzalez Rogers will preside; the court divided the proceedings into a liability phase and a remedies phase, with liability expected to run into mid-May and an advisory jury.

Musk vs Altman: OpenAI Dispute Moves to Court
Elon Musk has taken his long-running allegation of fraud against OpenAI and CEO Sam Altman to trial. According to reporting cited by t3n, jury selection begins the week of April 27, 2026, and the trial is expected to last two to three weeks. Musk argues that OpenAI’s 2025 restructuring — which created a for‑profit core while retaining oversight by the original nonprofit — violated the founders’ agreement; he seeks Altman’s removal and more than $134 billion in damages to be redirected to OpenAI’s nonprofit arm. OpenAI denies the claims, published internal communications it says show Musk knew of the plans, and characterizes the suit as motivated by jealousy. The case could expose private depositions and documents publicly and has implications for OpenAI’s planned IPO and corporate governance of major AI labs.
