NYC Comptroller Urges Anthropic to Pause IPO Until It Addresses AI Safety Concerns

Anthropic’s calls for caution on AI are now being turned back on its planned stock-market debut. In an October 14, 2026 letter, New York City Comptroller Mark Levine urged CEO Dario Amodei to pause the company’s initial public offering until it addresses safety, governance and development-speed concerns—not simply warns about them.

Levine brings the perspective of a major pension-fund official to that demand. He serves as investment adviser, custodian and a trustee of New York City pension funds holding more than $325 billion in assets. His letter frames Anthropic’s safety strategy and governance as issues investors must assess, rather than concerns separate from the company’s financial future.

The intervention is a request, not an order halting the offering. Levine asks Anthropic to stop the process while it addresses the issues he identifies, and requests a written response. The letter does not impose a binding requirement on the company.

The letter’s most specific demand concerns how safety commitments would work. Levine asks for disclosures detailed enough to explain what Anthropic will implement, what those measures are meant to cover, and when they will be in place. He identifies three connected questions:

• Implementation: How will Anthropic put appropriate audits and controls into operation?
• Scope and timing: What risks will those controls address, and what is the projected implementation timeline?
• Development pace: Will the controls sufficiently address Amodei’s call to slow improvements in AI capabilities, and how?

Levine also rejects a recent White House accord as an adequate answer. His letter says Anthropic and five other companies signed the agreement, described as “morally binding.” He argues that the company needs a governance regime matching the seriousness of the risks raised by its leadership, researchers, policymakers and the public.

The demands of preparing for a public offering diverts resources and attention from this very necessary work.

Levine builds his argument around Amodei’s September 12 essay, “We Must Pace the Frontier.” The letter quotes Amodei saying developers must slow the pace of improvements in AI model capabilities. Levine argues that prudence should apply not only to the technology’s development, but also to the timing of Anthropic’s move into public markets.

Citing news reports, Levine also points to warnings in Anthropic’s draft stock-offering registration document, known as an S-1. His letter says the document describes potential “catastrophic or existential risks to humanity” and contains 80 pages of risk disclosures—nearly twice the length of its business section. He treats that reported imbalance as evidence of unusually serious investor concerns.

Those warnings are not established predictions of what AI will do. Levine explicitly allows that the outcomes could prove overstated. His argument is that even so, the severity of the company’s stated concerns illustrates economic risks that investors need to weigh before an offering proceeds.

Governance is the other part of Levine’s challenge. The letter identifies Anthropic as a Delaware public benefit corporation with a Long-Term Benefit Trust. Citing press reports about a proposed structure concentrating control among founders and trustees, Levine warns that a gap between control and accountability would be particularly concerning given the risks Anthropic has acknowledged.

The potential scale of the offering adds to his concern. Levine cites reports that an IPO could value Anthropic at approximately $2 trillion; that is a reported possibility, not a confirmed offering value. He asks investors to assess the company’s revised development strategy, governance commitments and changing risk landscape.

Anthropic did not immediately respond to PYMNTS’ request for comment, the outlet reported on October 15. Levine’s requested written response would give the company an opportunity to explain how its safeguards and governance address the concerns he has raised before it proceeds with the planned offering.
