Elon Musk and Sam Altman spar on X after Apple files OpenAI lawsuit

This article covers a public dispute between Elon Musk and Sam Altman on X (a social platform Musk owns) following Apple's lawsuit against OpenAI over alleged trade secret theft. The conflict stems from a long-standing disagreement over OpenAI's transformation from a nonprofit to a for-profit structure, which Musk lost in court earlier in 2026, and intensified as both leaders promoted competing AI models (Musk's Grok 4.5 and Altman's GPT-5.6 Sol).
