Musk Escalates Altman Legal Feud, Casting OpenAI as Monopolist

Elon Musk is ramping up his feud with Sam Altman, alleging in a court filing that OpenAI is trying to corner the market for generative artificial intelligence and sacrificing safety in a race to get ahead.

In a revised version of a lawsuit he filed in August, Musk highlighted antitrust concerns about OpenAI’s journey from its nonprofit roots in 2015 — when he and Altman worked together as founders — to its current effort to restructure as a for-profit company following billions of dollars in outside investment by Microsoft and others.

Musk, who launched his xAI startup last year, said OpenAI has now abandoned all pretense of proceeding as a charity to benefit humanity with a focus on openness and safety as it tries to complete its restructuring.

“Microsoft and OpenAI, apparently unsatisfied with their monopoly, or near so, in generative artificial intelligence (“AI”) are now actively trying to eliminate competitors, such as xAI, by extracting promises from investors not to fund them,” lawyers for the billionaire wrote in the amended complaint filed late Thursday in federal court in Oakland, California.

The revised suit lists 26 legal claims and runs 107 pages, compared with 15 claims in the 83-page original complaint.

In a statement Friday, OpenAI rejected the claims and provided a web link to a collection of emails it said showed Musk had previously supported the for-profit structure. “Elon’s third attempt in less than a year to reframe his claims is even more baseless and overreaching than the previous ones,” OpenAI said. “His prior emails continue to speak for themselves.”
