OpenAI files motion to dismiss xAI antitrust lawsuit, citing SpaceX disclosures

OpenAI filed a motion asking US District Judge Mark Pittman to dismiss xAI's antitrust lawsuit before it reaches trial. The core of xAI's complaint is that Apple's exclusive integration of ChatGPT into its ecosystem unlawfully foreclosed competitors like Grok. OpenAI's counter is pointed: it argues that SpaceX's own IPO registration statement contains disclosures 'diametrically opposed' to those market-foreclosure claims — in effect using Musk's own corporate filings against his AI company.

The legal maneuver is notable for turning the SpaceX linkage — which xAI touts as a data and engineering advantage for Grok — into a liability. If SpaceX's SEC disclosures characterize the competitive landscape in ways that contradict xAI's allegations of being shut out, that inconsistency could undermine the antitrust theory at the pleading stage.

The suit is one front in the broader Musk-OpenAI feud that has spanned governance disputes, the for-profit conversion fight, and now competition law. It also intersects with Apple's AI strategy: Apple's ChatGPT integration is the specific conduct at issue, making the case consequential for how exclusive AI partnerships between platform owners and model providers are treated.

With trial scheduled for January, the dismissal motion is an attempt to end the case early rather than litigate the merits. Observers should watch how Judge Pittman weighs the SpaceX-disclosure argument — whether it's dispositive or merely a factual dispute for trial — and whether the ruling sets any precedent on platform-model exclusivity deals more broadly.
