The news
New York City AI regulation moved from proposal to confrontation on September 28, when Council Speaker Julie Menin said Anthropic, OpenAI, Google and Meta will testify under oath on October 5 and subpoenaed Elon Musk's SpaceXAI to appear.
The hearing, a Committee of the Whole session convening all 51 council members, will consider a package Menin unveiled on September 25. The broadest bill, Introduction 2602, would make it unlawful to market, sell or deploy an AI system in the city without third-party validation covering data quality, bias, decision outputs, privacy and security, and would require every such system to have a kill switch, a human override that can shut it down. Both the business and the validator would face a $25,000 penalty for each violation.
Other bills would give whistleblowers a share of penalties recovered from AI companies, which the council calls a first in the nation; create a private right of action for people harmed when third parties get around an AI tool's safety controls, if the harm was foreseeable and safeguards were unreasonable; require city contractors to report AI safety incidents within 24 hours; ban false or misleading safety claims; and set privacy rules for chatbots.
According to the council's September 28 release, Menin wrote to the five companies between September 15 and 17. Meta agreed to send a senior leader, Google and Anthropic declined by a September 25 deadline, and after the council authorized subpoenas, OpenAI and Google agreed on September 27 and Anthropic late that night. SpaceXAI had not responded. The council said it may seek court enforcement if SpaceXAI does not comply.
Menin told Fortune the $25,000 fine would apply per agent if a swarm of agents is involved. Her stated position, in the council's September 25 release: "We can and must be both pro-innovation and pro-safety." That September 25 release also cites the July incident in which AI agents tested by OpenAI reportedly compromised systems at Hugging Face.
The numbers
- Penalty per violation (Intro 2602)
- $25,000
- Incident reporting window for city contractors
- 24 hours
- Council members at October 5 hearing
- 51
- Bills listed in the initial package
- 10
Why CEOs should care
For any company that sells or deploys AI in New York City, including software vendors, banks, retailers and health systems, the validation bill is the one to model. As written in the council's summary, it covers any AI system marketed, offered or deployed in the city, not just frontier models, and it makes both the business and its validator liable. General counsels should map which products and internal tools would fall under the definition, and ask vendors whether they could produce independent validation and a documented human override on short notice. Marketing and product teams should also note the separate bill barring false or misleading safety claims about AI tools, which would reach product copy and sales materials.
CFOs should look closely at how penalties would be counted. If fines apply per instance, and per agent in a swarm as Menin described, exposure for a company running many automated agents could grow quickly. Budget for third-party validation costs and for engineering work to add kill switches where none exist.
CISOs and procurement leads at city contractors face a nearer deadline in practice: a 24-hour notice requirement for AI safety incidents, plus public disclosure by the city within 24 hours. Review incident definitions and escalation paths now, and ask AI suppliers how quickly they can confirm and report an incident.
The bigger picture
The package is part of a broader shift toward state and local action while Congress debates. Fortune noted that a bipartisan Senate safety bill from Sens. Ted Cruz, Amy Klobuchar and John Thune would likely override most state laws, and that a Justice Department task force created to sue states over their AI laws made Colorado its first target. New York City's leverage is that AI companies are expanding there: Fortune reported that Anthropic leased a 16-story building in Manhattan and expects more than 1,000 employees in the city by year-end.
What’s next
The October 5 hearing is the next milestone. Watch whether SpaceXAI complies with the subpoena, what the four labs say under oath about recent agent incidents, and whether the bills are amended to narrow which AI systems need validation. Also watch Congress: Fortune reported that the bipartisan Senate bill would likely override most state AI laws, though its reporting did not address city rules. The council has also said more bills are coming, including a ban on deceptive deepfakes and a study of how algorithmic tools change job duties.
What “Fact-checked” means
Fact-checking means testing a story’s facts against the evidence before it is published. This story went through at least two separate checks before this version was published.
- What we checked
- Its names, figures, dates, job titles, quotes and who said what were checked against the story’s sources, including its main source where it could be opened. The headline was checked for accuracy and overstatement.
- How
- A first check reviewed the whole story. If it passed, a second, skeptical check went back to the sources to look for mistakes in the most important facts. If a check flagged the story, it was edited to fix the problems found, and a separate re-check then reviewed the whole story again.
- Who
- The checks are made by our newsroom, as steps kept separate from the writing, under rules set by our editor, Hussein Mukhtar. A story the checks still flag is held for the editor, who decides whether it is fixed, published or dropped.
- If something is wrong
- “Fact-checked” does not mean error-free. If a material error is found after publication, we correct the story and add a note saying what changed. Report an error
