# OpenAI accuses Musk of 'anti-competitive behavior,' asks state AGs to investigate

_Monday, April 6, 2026 at 2:30 AM EDT · AI, Policy · Latest · Tier 1 — Major_

OpenAI has escalated its legal battle with Elon Musk by sending letters to the California and Delaware attorneys general, urging investigations into what it calls "anti-competitive behavior" by Musk and his associates. The move comes weeks before an April trial in which Musk seeks to block OpenAI's for-profit conversion. OpenAI alleges Musk has used his influence and resources to undermine competitors while advancing his own AI ventures. The company is pushing state regulators to examine whether Musk's actions violate antitrust laws. The dispute stems from Musk's founding role at OpenAI and his subsequent departure, followed by his establishment of rival AI company xAI. OpenAI's request for regulatory intervention marks a significant shift from purely litigation-based strategies to invoking government enforcement mechanisms.
