Sam Altman finally stood up to Elon Musk after years of X trolling

Much attention was paid to OpenAI's Sam Altman and xAI's Elon Musk trading barbs on X this week after Musk threatened to sue Apple over supposedly biased App Store rankings privileging ChatGPT over Grok.

But while the heated social media exchanges were among the most tense ever seen between the two former partners who cofounded OpenAI—more on that below—it seems likely that their jabs were motivated less by who's in the lead on Apple's "Must Have" app list than by an impending order in a lawsuit that landed in the middle of their public beefing.

Yesterday, a court ruled that OpenAI can proceed with claims that Musk was so incredibly stung by OpenAI's success after his exit didn't doom the nascent AI company that he perpetrated a "years-long harassment campaign" to take down OpenAI.

Musk's motivation? To clear the field for xAI to dominate the AI industry instead, OpenAI alleged.

OpenAI's accusations arose as counterclaims in a lawsuit that Musk initially filed in 2024. Musk has alleged that Altman and OpenAI had made a "fool" of Musk, goading him into $44 million in donations by "preying on Musk’s humanitarian concern about the existential dangers posed by artificial intelligence."

But OpenAI insists that Musk's lawsuit is just one prong in a sprawling, "unlawful," and "unrelenting" harassment campaign that Musk waged to harm OpenAI's business by forcing the company to divert resources or expend money on things like withdrawn legal claims and fake buyouts.

"Musk could not tolerate seeing such success for an enterprise he had abandoned and declared doomed," OpenAI argued. "He made it his project to take down OpenAI, and to build a direct competitor that would seize the technological lead—not for humanity but for Elon Musk."
