OpenAI said its ChatGPT integration with Apple's Siri 'dramatically underperformed' after launching in December 2024, according to court filings in its lawsuit with Elon Musk's SpaceXAI. The company cut its forecast for incremental weekly active users by January 2025 and asked Apple for a two-year exclusivity period, which Apple refused. OpenAI now seeks dismissal of the antitrust claims before a trial scheduled for January 2027.

Key Facts

OpenAI cut its forecast for incremental logged-in weekly active users from the Apple partnership by January 2025.
OpenAI asked Apple for a two-year exclusivity period, but Apple refused, citing the non-exclusive agreement.
Apple signed a deal with Google, and Apple's newest models are based on Gemini.
Musk's companies dropped their claims against Apple earlier this month, leaving OpenAI as the sole defendant.
OpenAI's expert Dr. Catherine Tucker calculated foreclosure shares of [REDACTED] across all metrics, consistent with minimal Apple Intelligence usage.

Underperformance Details

Apple added ChatGPT to Siri in December 2024, but users had to go through a multistep opt-in process, which added a layer of friction. By January 2025, OpenAI said the integration was 'off to a slow start' and the company cut its forecast for the number of incremental logged-in weekly active users that it expected to get from the partnership. OpenAI said that by the time Musk's companies filed an antitrust lawsuit against Apple and OpenAI, 'it was clear that Apple's integration of ChatGPT was dramatically underperforming.' In a later section of the filing, OpenAI said again that the Apple integration was 'persistently underperforming,' leading to a March 2026 conversation between Apple and OpenAI that is redacted.

Exclusivity Dispute

OpenAI asked Apple for a two-year exclusivity period, but Apple refused. The agreement between the two companies explicitly said the deal was non-exclusive and Apple had the right to 'integrate products or services that provide the same or similar functionality as [ChatGPT].' Apple told OpenAI that it planned to integrate one provider and then add more, and it made similar statements publicly when announcing the feature. Apple also signed a deal with Google, and Apple's newest models are based on Gemini.

Lawsuit Status

Musk's companies dropped their claims against Apple earlier this month, leaving OpenAI as the sole defendant in the lawsuit. OpenAI's filing asks the court to toss out xAI's claims prior to the trial planned for January 2027. OpenAI's expert, Dr. Catherine Tucker, calculated the share of GenAI consumers who accessed ChatGPT through Apple Intelligence across multiple metrics using the same data and market definition relied upon by Plaintiffs' experts. On these assumptions, Dr. Tucker found foreclosure shares of [REDACTED] across all metrics, consistent with OpenAI's internal view that Apple Intelligence saw minimal usage.
