Elon Musk Seeks Up to $134 Billion From OpenAI and Microsoft

Jan 17, 2026
Elon Musk is demanding up to $134 billion in damages from OpenAI and Microsoft, claiming they gained wrongful profits from his early involvement in the AI startup. The case, set for trial in April, follows a judge’s decision to let a jury hear the dispute.

Elon Musk is seeking between $79 billion and $134 billion in damages from OpenAI and Microsoft, according to Bloomberg. The claim stems from allegations that OpenAI defrauded Musk by abandoning its nonprofit mission and partnering with Microsoft.

The damages figure was determined by financial economist C. Paul Wazzan, who calculated that OpenAI gained $65.5 billion to $109.4 billion and Microsoft $13.3 billion to $25.1 billion from Musk’s early contributions. Musk’s legal team argues he is entitled to a share of OpenAI’s current $500 billion valuation, citing his $38 million seed donation and early involvement in the company’s formation.

The lawsuit follows a January ruling that the case will go before a jury in April. OpenAI and Microsoft have both dismissed the claims, describing Wazzan’s calculations as unverifiable and unprecedented. OpenAI stated that the lawsuit is part of a continuing pattern of harassment.

Musk left OpenAI’s board in 2018 and later founded his own AI firm, xAI. His filing also indicates he may seek punitive damages and an injunction if the jury finds either company liable.
