OpenAI says Apple Intelligence ChatGPT integration underperformed as it seeks pretrial ruling
OpenAI told a court that ChatGPT's integration with Apple Intelligence “dramatically underperformed” after its 2024 launch, as it seeks a pretrial ruling in SpaceXAI's antitrust lawsuit.
In August 2025, Musk said X, now part of SpaceXAI, would sue Apple and OpenAI over alleged collusion to shut competitors out of the AI market. The dispute stemmed from OpenAI's deal with Apple to make ChatGPT part of Apple Intelligence and Siri. When the lawsuit was filed, it went beyond Musk's public complaint about App Store rankings: X and SpaceXAI also accused Apple of trying to stifle the development of “super apps,” including X's effort to become an “everything app.”
Apple and OpenAI have argued that their deal was not exclusive, as the complaint alleged. In the latest filing, OpenAI said it was disappointed by how little interest Apple generated from iPhone users after the two companies struck the 2024 deal for ChatGPT to power Apple Intelligence.
When the deal was agreed, OpenAI expected a “halo effect” from promotion and brand association with Apple, along with more subscriptions from Apple Intelligence users, according to the court document cited by The Financial Times. But a month after the ChatGPT integration launched, it “appeared to be off to a slow start,” and OpenAI cut forecasts for expected weekly active users. By the summer of 2025, OpenAI said, “it was clear that Apple's integration of ChatGPT was dramatically underperforming.”
The filing contains multiple redacted conversations. The unredacted portions show that OpenAI executives were concerned Apple could “want to move faster” to secure another AI partner, according to the report. When Apple Intelligence was announced in 2024, Craig Federighi said in an interview that Apple ultimately wanted users to be able to choose between different AI models, specifically pointing to Google Gemini as a potential future integration. That partnership never materialized, but Apple has since turned to Google's Gemini models to help power the new Siri AI, while Xcode has expanded to support coding agents from Anthropic, Google, and OpenAI.
The Financial Times noted that the filing also points to the way Apple implemented ChatGPT as a possible reason for slow adoption: the integration was turned off by default. Reuters reported that OpenAI is also arguing that recent securities disclosures from SpaceX undermine SpaceXAI's claims that the Apple partnership harmed competition. OpenAI said SpaceX's IPO registration statement was “replete with disclosures diametrically opposed” to the competitive harm alleged in the lawsuit.
OpenAI is asking Judge Mark Pittman to rule in its favor before trial on SpaceXAI's antitrust claims. The case is currently set to go to trial in January.
