OpenAI alleges Elon Musk sent threatening text messages to its executives in a new court filing.
The messages followed a failed settlement attempt on April 25, 2026.
The attempt occurred just days before the trial began.
Musk reportedly told OpenAI President Greg Brockman that he and Sam Altman would become the most hated men in America.
Musk allegedly added that if they insisted on the trial, so it would be.
OpenAI lawyers seek to introduce the exchange as evidence of Musk's intent to attack a competitor and its principals.
Musk’s 2024 lawsuit claims OpenAI abandoned its non-profit mission by adopting a for-profit model with Microsoft.
The ongoing trial includes expected testimony from Sam Altman and Microsoft CEO Satya Nadella.
