Yes—but Elon Musk did not personally file the case. On August 25, 2025, X Corp. and xAI LLC sued Apple and several OpenAI entities in federal court, alleging that Apple and OpenAI worked together to disadvantage rival artificial-intelligence products, particularly xAI’s Grok chatbot.
The lawsuit remains an allegation, not a finding that Apple or OpenAI violated antitrust law. The latest docket materials located for this report show active discovery and disputes over evidence, with no established final judgment on the merits.
Who sued whom?
The case is X Corp. et al. v. Apple Inc. et al., No. 4:25-cv-00914-P, in the U.S. District Court for the Northern District of Texas, Fort Worth Division. The named plaintiffs are X Corp., operator of the X platform, and xAI LLC, the company behind Grok—not Musk personally. The defendants include Apple Inc. and multiple OpenAI entities.
Calling it “Musk’s lawsuit” is understandable shorthand because Musk controls or is closely associated with the plaintiff companies. Legally, however, the corporate entities brought the antitrust case. The filed complaint is available in the court filing.

What triggered the lawsuit?
The immediate public trigger was Musk’s criticism of Apple’s App Store rankings. Earlier in August 2025, he accused Apple of making it effectively impossible for an AI company other than OpenAI to reach the top position and threatened legal action, according to reported coverage.
X and xAI filed the complaint on August 25. The lawsuit also focuses on Apple’s June 2024 announcement that ChatGPT would be integrated into Apple Intelligence and related operating-system features. A later court order describes that Apple–OpenAI integration as part of the factual background of the dispute.
What does X and xAI allege?
The complaint presents a broader theory than simply “Grok received a low ranking.” Its central allegations include:
Rank #2
- Preferential integration: Apple allegedly gave ChatGPT privileged access to the iPhone and Apple’s operating-system ecosystem.
- App Store visibility: Apple allegedly favored OpenAI in rankings, recommendations, or other forms of App Store visibility.
- Disadvantage to competitors: The alleged arrangement harmed rival AI chatbots, including Grok.
- Platform leverage: Apple and OpenAI allegedly used their positions to protect or extend market power in AI distribution.
- Broader business effects: The plaintiffs connect the alleged conduct to xAI’s ability to compete and to Musk’s wider plans for an X-based “super app.”
These are claims made by the plaintiffs. The available materials do not establish that Apple rigged the App Store, illegally blocked Grok, or colluded with OpenAI.
Why ChatGPT integration matters
Apple’s ChatGPT arrangement involves more than making a chatbot available as an ordinary downloadable app. ChatGPT was integrated into Apple Intelligence and related iPhone functions. X and xAI characterize that arrangement as uniquely privileged or effectively exclusive because ChatGPT received system-level access that competing providers did not receive on comparable terms.
That distinction is important:
- Integration concerns access through Apple’s system-level AI features.
- App Store ranking concerns how apps appear in lists, recommendations, or search-related visibility.
- Exclusivity is a legal characterization advanced by the plaintiffs and is not an established court finding.
The complaint attempts to connect these issues into an antitrust theory: Apple’s control over device-level distribution and the App Store allegedly gave OpenAI an advantage while making it harder for competitors such as Grok to reach users.
What Apple and OpenAI argue
Apple disputes the plaintiffs’ theory and filed a motion to dismiss. In its supporting brief, Apple argued that the claims fail and pointed to objective explanations for Grok’s position in the App Store. Those are Apple’s litigation arguments, not findings by the court.

Apple and OpenAI also challenged the plaintiffs’ handling of potentially relevant communications. In February 2026 filings, they argued that Musk and personnel at his companies used ephemeral messaging services, including Signal and XChat, and that relevant material had not been adequately preserved. The surfaced materials show defense allegations and discovery arguments—not a final finding that Musk or xAI destroyed evidence.
What has happened in court?
| Date | Development | What it means |
|---|---|---|
| August 25, 2025 | X Corp. and xAI filed the federal antitrust complaint in Texas. | The case formally began. |
| January 22, 2026 | A magistrate judge ruled on discovery disputes involving the Apple–OpenAI integration and denied part of a motion to compel. | The court was managing evidence requests; it did not decide liability. |
| February 2, 2026 | Apple and OpenAI filed arguments concerning preservation of Signal, XChat, and other potentially relevant communications. | The parties were disputing the scope and preservation of discovery. |
| June 2, 2026 | District Judge Mark Pittman overruled the plaintiffs’ objection and affirmed an order requiring certain business emails from Musk-controlled SpaceX and Tesla accounts to be produced when they contained relevant X or xAI communications. | The ruling concerned discoverability of evidence, not whether Apple or OpenAI violated antitrust law. |
| June 3, 2026 | The court ordered additional production by July 3, 2026. | The latest located materials continue to show an active discovery process. |
Based on the latest docket material located for this report, the case remained in discovery rather than having reached a final merits judgment. The sources do not establish whether the July 3 production was completed or whether a later ruling resolved the case.
What relief are the plaintiffs seeking?
X and xAI seek antitrust relief and damages. Docket material lists a multibillion-dollar damages demand—reported at approximately $9.999 billion—but that figure is a demand by the plaintiffs, not money awarded by a court.
The complaint also seeks other antitrust remedies. The precise outcome, if any, would depend on later rulings, settlement, or trial proceedings.

What the lawsuit does not establish
- It does not establish that Apple “banned” or blocked Grok from the App Store.
- It does not establish that Apple and OpenAI illegally colluded.
- It does not establish that Apple suppressed Grok as a matter of fact.
- It does not establish that Musk won or lost the case.
- It does not establish liability merely because the court ordered discovery from certain Musk-controlled accounts.
To prevail, the plaintiffs would generally need to connect the alleged conduct to a legally cognizable market, market power, and anticompetitive harm—not merely show that Grok ranked below another app or that Apple preferred one integration partner.

Why the case matters
The dispute raises a broader question for the technology industry: can a device platform integrate one AI provider into its operating system while claiming to treat competing AI apps neutrally in its app marketplace?
The answer could affect how AI assistants are distributed, how operating-system partnerships are structured, and how App Store rankings and recommendations are scrutinized. It is also relevant to investors and consumers because control over default or system-level access can influence which AI services gain users, data, and revenue.
For now, the practical takeaway is narrower: X and xAI have accused Apple and OpenAI of using an integration and distribution relationship to disadvantage rivals, but the available court record shows an unresolved lawsuit—not a judicial determination that those accusations are true.
Do not confuse this case with Musk’s other OpenAI lawsuit
Musk has separately sued or pursued litigation against OpenAI over allegations that it abandoned its original nonprofit and public-benefit mission. That dispute is legally and factually distinct from the Texas antitrust case involving Apple’s alleged treatment of OpenAI and Grok. The two matters should not be treated as one lawsuit.
