Musk described $80 billion Mars plan at OpenAI trial

Greg Brockman, president of OpenAI, testified during the Musk v. OpenAI trial in Oakland that in 2017 Elon Musk backed converting OpenAI from a nonprofit to a for-profit structure because the nonprofit model made it hard to raise the capital needed, Reuters reports. Brockman testified that Musk said he deserved a majority stake and intended to use that stake to raise $80 billion to build a self-sustaining city on Mars, and Brockman quoted Musk saying, "He said he needed $80 billion to create a city," Reuters reports. Brockman also told the court that OpenAI plans to spend $50 billion on computing resources in 2026, Reuters reports. Reuters and related coverage note that Musk is seeking $150 billion in damages and wants Sam Altman and Brockman removed from leadership, and that Musk left OpenAI's board in February 2018.

The testimony foregrounds two quantifiable claims from the court record: the $80 billion figure tied to Musk's Mars remarks, and OpenAI's reported plan to spend $50 billion on compute in 2026, as stated by Brockman on the stand, Reuters reports. For practitioners, the latter number underscores the scale of capital allocation that major frontier-model efforts are publicly acknowledging. Industry-pattern observations: organizations building large generative models increasingly disclose multi-year, multi-billion-dollar compute commitments, which affects procurement, spot-market GPU demand, and vendor negotiation leverage.

The trial concerns governance and the transformation of OpenAI's legal structure, matters that shape how capital, control, and mission interact in frontier-AI projects. Reporting by Reuters frames Musk's claim about an $80 billion Mars fund as part of his argument for majority control, while the plaintiff relief sought, $150 billion in damages, is a legally high-stakes demand according to Reuters. Observed patterns in similar disputes: governance contests at research organizations often hinge on fundraising models and equity arrangements, and they can produce prolonged litigation with implications for investor confidence and partner commitments.

Observers should track testimony excerpts and court filings for corroboration of the timeline and any documentary evidence that substantiates the alleged 2017 conversations, as reported by Reuters. Industry observers will also monitor whether the trial produces more detailed disclosures about OpenAI's projected compute spend and contractual terms with cloud and chip vendors, since such details influence capacity planning across the AI infrastructure market. Finally, watch for any judicial rulings that materially affect OpenAI's corporate structure or the enforceability of its historical agreements, as reported in follow-on Reuters coverage.
