Musk Demands Up to $134 Billion in OpenAI Lawsuit Amid $700B Fortune

Elon Musk is seeking a staggering $79 billion to $134 billion in damages from OpenAI and Microsoft, alleging the AI company misled him by abandoning its nonprofit mission, Bloomberg first reported.

The eye-popping figure comes from expert witness C. Paul Wazzan, a financial economist with a track record of nearly 100 depositions and more than a dozen trial testimonies in complex commercial litigation.

Expert Analysis Supports Massive Claim

Wazzan, who specializes in valuation and damages in high-stakes disputes, concluded that Musk is entitled to a significant portion of OpenAI’s current $500 billion valuation, based on his $38 million seed donation when he co-founded the company in 2015.

To put that in perspective, Wazzan’s analysis implies a 3,500-fold return on Musk’s initial investment. His calculations take into account not only Musk’s financial contributions but also his early technical and business input, resulting in estimated wrongful gains of:

• OpenAI: $65.5 billion – $109.4 billion

• Microsoft: $13.3 billion – $25.1 billion (Microsoft now owns a 27% stake in the company)

Musk’s legal team argues that, as an early investor, he should be compensated for returns “many orders of magnitude greater” than his initial stake.

The Lawsuit’s Broader Context

Despite the enormous figures involved, the legal battle appears to extend beyond simple financial compensation. Musk’s personal wealth is currently around $700 billion, making him the world’s richest person, according to Forbes’ billionaires list. His fortune surpasses that of Google co-founder Larry Page by roughly $500 billion, Reuters recently noted.

In November, Tesla shareholders approved a $1 trillion pay package for Musk—the largest corporate pay deal in history—further emphasizing the scale of his financial standing.

OpenAI Pushback and Trial Details

Even if Musk were awarded the full $134 billion, it would represent a relatively small fraction of his wealth. OpenAI has reportedly characterized the lawsuit as part of an “ongoing pattern of harassment” rather than a legitimate claim for compensation.

The company reportedly sent a letter to investors and business partners on Thursday, warning that Musk may make “deliberately outlandish, attention-grabbing claims” as the case heads to trial in April.

The trial will take place in Oakland, California, roughly 15 miles east of San Francisco.

This case is shaping up as one of the most high-profile clashes in the AI industry, highlighting both the massive stakes of early tech investments and the growing tensions over OpenAI’s shift from a nonprofit mission to a commercially lucrative enterprise.
