Elon Musk has withdrawn his antitrust claims against Apple over its ChatGPT integration but is continuing his legal fight against OpenAI on the same issue. Musk had accused Apple and OpenAI of colluding to create a "monopoly" on AI prompts through the iPhone's ChatGPT integration, harming competition in both the smartphone and chatbot markets, and had separately alleged that Apple was blocking his own chatbot, Grok, from topping App Store rankings. The move matters because it narrows a high-profile case just as it heads towards trial, leaving OpenAI to fight the claims alone while Musk's rival AI venture continues to compete with it.

In a Monday court filing, Musk confirmed he had resolved all claims against Apple and agreed never to raise them again, though no settlement terms were disclosed. He is still pursuing OpenAI on the theory that it exploited the (non-exclusive) Apple deal to monopolise the chatbot market, estimating its market foreclosure at anywhere between 0 and 55 percent, a figure OpenAI has dismissed as guesswork. OpenAI, which has separately claimed the Apple partnership underperformed commercially, casts the suit as harassment, while both companies have argued Musk lacks standing since none of his firms compete in smartphones; Musk may have dropped Apple after obtaining internal company messages about the deal through court-ordered disclosure this summer.
