OpenAI Calls on California and Delaware to Probe Musk’s Anti‑Competitive Conduct Ahead of

OpenAI’s legal team has turned the spotlight on Elon Musk, filing a formal request with the attorneys general of California and Delaware to examine whether the billionaire’s recent moves constitute “anti‑competitive behavior,” according to a CNBC report. The timing is deliberate: the letter lands just weeks before OpenAI’s high‑stakes trial in April, a proceeding that will determine how the company can continue to monetize its flagship models amid a rapidly consolidating AI market. By invoking state‑level antitrust scrutiny, OpenAI is betting that regulators can add pressure to Musk’s parallel push to dominate generative AI through his own ventures, a strategy that has already rattled competitors and investors alike.

The correspondence, which Reuters also covered, outlines specific concerns about Musk’s alleged coordination with “associates” to undercut OpenAI’s market position. While the letter does not disclose the precise tactics under investigation, it signals a shift from private litigation to a broader, public‑policy arena. OpenAI’s leadership appears to be leveraging the dual jurisdiction of California—home to many tech giants—and Delaware, the corporate haven for countless U.S. companies, to maximize the investigative reach. This move could force Musk’s enterprises to defend their business practices not just in court but before state regulators equipped with antitrust powers.

Industry observers note that the request arrives at a moment when the AI sector is experiencing a surge of “winner‑takes‑all” dynamics, with large language models becoming the backbone of everything from search to customer service. By framing Musk’s conduct as potentially anti‑competitive, OpenAI is positioning itself as a guardian of a more open market, even as it continues to lock down its own proprietary technology. The letter’s language, as described by CNBC, underscores a strategic narrative: OpenAI is not merely defending its own revenue streams but is also warning that unchecked consolidation could stifle innovation across the broader ecosystem.

If California and Delaware decide to open formal probes, the implications could ripple far beyond the immediate legal battle. State antitrust investigations can lead to hefty fines, mandatory divestitures, or injunctions that reshape how companies collaborate and compete. For OpenAI, a successful probe would add a powerful lever to its ongoing courtroom fight, potentially swaying the April judge’s view of market dynamics. For Musk, it could mean a new front in an already crowded war over AI supremacy—one that forces his ventures to justify aggressive pricing, talent poaching, or exclusive partnerships under the glare of public regulators. The outcome remains uncertain, but the letter marks a bold escalation in a contest that is shaping the future of artificial intelligence.
