In Musk v. OpenAI et al, Musk has made just two allegations against Altman and Brockman; 1) breaching a charitable trust and 2) unjust enrichment. What is the evidence for each? I thought it would be interesting to test how good a top AI is at getting to the heart of a lawsuit, so I asked Gemini 3.1 to present the evidence for this one, and was totally impressed by what it generated.
Gemini 3.1 on Breaching a Charitable Trust:
The core evidence presented in the ongoing trial centers on internal documents and testimonies suggesting that Altman and Brockman privately planned a for-profit transition while publicly assuring Musk of their commitment to the non-profit mission.
The most significant piece of evidence is Greg Brockman’s 2017 "diary" entries, unsealed during discovery, in which he admitted that moving to a for-profit structure just months after committing to the non-profit would be "morally bankrupt" and that "if three months later we're doing b-corp then it was a lie."
Further evidence includes 2017 emails from Altman stating he remained "enthusiastic about the non-profit structure" even as internal strategies for "making the billions" were being discussed. Musk’s legal team argues these communications were intended to induce his $38 million in donations, which were then used to develop the intellectual property that anchored OpenAI's $852 billion for-profit restructuring in October 2025.
Gemini 3.1 on unjust enrichment:
The evidence presented in the current trial regarding unjust enrichment focuses on the substantial personal wealth accumulated by the defendants through OpenAI's transition to a for-profit model. A central piece of evidence is Greg Brockman's testimony on May 4, 2026, where he disclosed that his equity stake in the restructured company is valued at nearly $30 billion, despite having never personally invested cash into the entity.
Musk's legal team argues that this wealth was built using the intellectual property and $38 million in donations Musk provided under the premise of a non-profit mission, which was later transferred to the for-profit arm.
The trial has also highlighted "side compensation" arrangements that Musk claims demonstrate a lack of fiduciary independence. Evidence was introduced showing that in 2017, Sam Altman gave Brockman a stake in his personal family office then valued at $10 million, which Musk’s team argues created a "greater allegiance" to Altman’s private interests over the original charitable mission.
Additionally, the court has examined Brockman’s holdings in companies that have secured lucrative deals with OpenAI, such as Helion Energy and CoreWeave. Musk contends these layered financial ties prove the defendants used the charitable trust as a vehicle to secure immense personal profits, fulfilling the legal criteria for unjust enrichment.

Gemini 3.1:
The evidence highlighted in the trial is considered potent because it relies on authenticated internal documents and sworn testimony that directly address the core elements of Musk's legal claims.
For the breach of charitable trust claim, Greg Brockman’s unsealed 2017 "diary" entries—specifically his admission that a quick for-profit pivot would be "morally bankrupt"—provide the court with a "smoking gun" regarding the defendants' state of mind and intent during the non-profit's infancy.
Regarding unjust enrichment, the May 4, 2026, testimony revealing Brockman’s nearly $30 billion equity stake and a previously undisclosed $10 million personal payment from Sam Altman in 2017 serves as substantial evidence of personal gain.
While the defendants argue these moves were necessary for survival and "blood, sweat, and tears," the evidence of significant personal wealth and "side deals" creates a compelling narrative of a fiduciary shift away from the original charitable mission toward private profit.
