Republican attorneys general from Florida, Montana, Nebraska, Iowa, West Virginia, and Louisiana have written to SEC Chairman Paul Atkins asking him to investigate Sam Altman’s personal investment portfolio before OpenAI proceeds with its anticipated IPO. The House Oversight Committee opened a parallel probe on the same week, requesting governance documents and a briefing from a senior OpenAI executive.

The scrutiny is not new in substance, but the coordination and the timing are. OpenAI is targeting a public offering at approximately $1 trillion valuation. The Musk v. Altman trial running concurrently in Oakland has surfaced documents about Altman’s investment relationships that state-level officials are now using as the predicate for SEC referrals.

What the AGs Are Alleging

The attorneys general describe a pattern of “self-dealing and serious conflicts of interest.” The specific companies named include Helion Energy, a nuclear fusion startup in which Altman holds a personal stake and for which OpenAI signed an energy purchasing agreement, and Stoke Space, a rocketry startup Altman has backed personally while OpenAI pursued aerospace compute infrastructure.

The argument is structural: Altman controls OpenAI’s commercial partnerships. If OpenAI directs business toward companies Altman has personally invested in, the value of those investments rises — while OpenAI’s board, which Altman defends against in court as having been “transparent” about his disclosures, bears the governance risk.

OpenAI board chair Bret Taylor testified in the Musk trial that Altman had been “forthright” about outside investments and recused himself as required. OpenAI did not comment in response to press inquiries about the state AG letters.

House Oversight Committee

The House Oversight Committee, in a separate letter to Altman, asked for documents covering OpenAI’s governance practices, its processes for managing Altman’s conflict disclosures, and its procedures for approving commercial partnerships where a board member or executive holds a personal interest. The committee has not set a public hearing date.

IPO Implications

OpenAI restructured its governance in late 2024 and early 2025 as part of its conversion from a nonprofit capped-profit structure. The restructuring was designed in part to smooth the path to a public offering. Regulatory investigations at the state AG level and active SEC pressure letters create disclosure obligations and due diligence complexity for underwriters.

The Musk trial, running through mid-May, has already put Altman’s investment portfolio on the public record. Sutskever’s testimony cited specific concerns about Altman’s outside holdings as part of the 2023 board removal. Brockman disclosed a personal OpenAI equity stake approaching $30 billion in the same proceedings.

Whether the SEC acts on the AG letters before any IPO filing is the operative question. Atkins, installed by the current administration, has not signaled how he intends to respond.
