Elon Musk vs. Sam Altman: Trial Over OpenAI’s Nonprofit Promise
4/26/2026, 8:57:46 PM
Trial Overview
Elon Musk has filed a federal lawsuit in Oakland against OpenAI, CEO Sam Altman and president Greg Brockman, alleging breach of the nonprofit charter and unjust enrichment. He seeks removal of Altman and Brockman, reversal of OpenAI’s for-profit conversion, and damages up to $134 billion, to be paid to OpenAI’s charitable arm.
Background
OpenAI was founded in 2015 by Musk, Altman, Ilya Sutskever and others as a nonprofit research lab with the mission “to advance digital intelligence … for the benefit of humanity.” Musk contributed roughly $38 million before leaving the board in 2018. In 2019 the organization created a capped-profit subsidiary. ChatGPT’s 2022 success lifted the valuation to about $850 billion and set the stage for a planned IPO.

Data & Statistics
Musk contributed $38 million (other filings list $100 million or $50 million). He seeks $65.5 billion–$109.43 billion from OpenAI and $13.3 billion–$25.06 billion from Microsoft. OpenAI’s nonprofit holds equity in the for-profit arm valued at $130 billion–$180 billion; the company is valued at $852 billion.
Impact
The case tests whether AI firms can be forced to honor nonprofit commitments after large private investments, a decision that could affect OpenAI’s IPO, investor confidence, and policy debates on AI safety and public benefit.
Official Statements
OpenAI’s blog calls the suit “baseless” and a “harassment campaign” driven by “ego, jealousy and a desire to slow down a competitor.” Musk’s X posts label Altman a “liar” and “Scam Altman.” Altman calls Musk a “bully.” Legal scholar Michael Dorff says undoing the restructuring is “highly unlikely.”
Criticism
OpenAI’s lawyers call the suit petty and aimed at hindering competition; analysts note Musk’s damage estimates are speculative and charitable-trust claims hard to prove.
Conflicting Reports
Sources list Musk’s contribution as $100 million, $50 million or $38 million and damages from $134 billion to $150 billion; the complaint dropped from 26 to four claims.
