Elon Musk's xAI and X have filed a lawsuit against Apple and OpenAI, alleging monopolistic practices in the AI market. The suit claims Apple's integration of ChatGPT into iPhones gives OpenAI unfair advantages while restricting competition from rivals like Musk's Grok chatbot. Key allegations include biased App Store algorithms favoring OpenAI, structural barriers preventing the growth of alternative AI apps, and billions in damages to Musk's businesses. OpenAI dismissed the lawsuit as harassment, while Apple hasn't directly responded. The case highlights growing tensions over competition, transparency, and market power in both mobile and AI ecosystems.
