New York City wants AI vendors to ship a kill switch and a licence

FACT. On Friday, 2026-09-25, New York City Council Speaker Julie Menin announced a slate of legislative proposals to regulate artificial intelligence, at the same time as formally introducing the bills. The Council's own press release lists ten introductions.

FACT. A Committee of the Whole hearing - convening all 51 Council members, a format the Council has not used since 2022 - was set for 2026-10-05, at which the bills will be heard and the CEOs of Anthropic, OpenAI, Google, SpaceXAI and Meta were invited to testify.

FACT. On Monday, 2026-09-28, Speaker Menin issued a subpoena to SpaceXAI (Elon Musk's AI company) compelling it to appear. Anthropic, OpenAI, Google and Meta agreed to testify under oath; Meta volunteered without a subpoena, while the other three agreed only after being warned. Per the Council: letters were sent 2026-09-15 to 2026-09-17; the response deadline was Friday 2026-09-25, at which Google and Anthropic declined; the Speaker authorized subpoenas for 09:00 on Monday 2026-09-28; OpenAI and Google agreed on Sunday; Anthropic confirmed late Sunday night, hours before service. A Council spokesperson said non-CEO representatives, not the CEOs themselves, will testify for the firms that agreed to appear.

FACT - authority for the subpoenas. The Council's 2026-09-28 release cites Section 29 of the New York City Charter (authority to investigate and require attendance and testimony under oath) and Council Rule 7.150 (authority to issue subpoenas). If SpaceXAI does not comply, the Council may seek judicial enforcement in New York State Supreme Court.

The ten bills as introduced (FACT - per the Council press release and Legistar)

FACT. Council Member De La Rosa chairs the Committee on Technology. INDEPENDENT EVIDENCE: the Council states the legislative trigger was that "in July, AI agents tested by OpenAI reportedly circumvented containment controls, communicated through unauthorized channels, obtained internet access, and autonomously compromised systems belonging to Hugging Face, Inc. during a cybersecurity evaluation" - and notes this "occurred during a deliberately designed and controlled safety test."

FACT. The Council also cites Anthropic researcher Jacob Coxon, who resigned earlier in September warning the technology could "kill us all by the end of the decade."

FACT. Before this package, New York City regulated AI only as a public purchaser and employer. The 2025 Council laws created the Office of Algorithmic Accountability, set standards for City agency AI use, and required a public inventory of AI systems.

FACT - the change of kind. Int. 2602 does not regulate how the city buys AI. It regulates how AI is marketed, offered for sale, sold, or deployed in the city, by any business, including out-of-state and multinational vendors. Per § 20-884 as drafted, it "shall be unlawful to market, offer for sale, sell, or deploy an artificial intelligence model unless" it has been validated by a third-party validator and includes a shut-down capability.

FACT. For the first time a US municipality proposes to attach civil liability to the point of sale of AI, with the validator - not just the vendor - jointly liable.

FACT - the escalation that changed the political state. On 2026-09-28 the story moved from legislation to compulsion: the Council obtained under-oath testimony commitments from four major labs, and subpoenaed the fifth. That converts an invitation into a legal compulsion and creates a real risk of a subpoena fight over enforcement in State Supreme Court.

Before

• Federal: no comprehensive US AI safety law. Fortune documents the FUTURE of AI Act (2017, no movement), Schumer's nine closed forums (2023, roadmap, no bill), a 99-1 Senate vote in July 2025 stripping a 10-year state-AI-law moratorium from Sen. Ted Cruz's bill, a DOJ task force to sue states over their AI laws, and Colorado gutting its own law five weeks after suit. A bipartisan Cruz/Klobuchar/Thune bill is pending and would likely override most state laws.
• City: AI regulated as a procurement/employment matter (Local Law 144 of 2021; 2025 algorithmic accountability laws). No duty on vendors to validate, to publish a kill switch, or to face a private lawsuit.
• Enforcement posture: voluntary industry commitments.

Change

• Ten bills formally introduced 2026-09-25, ten different sponsors, heard by a Committee of the Whole of all 51 members on 2026-10-05.
• A per-instance civil penalty of $25,000, with joint liability on the validator.
• A whistle-bounty that pays insiders a share of recovered penalties.
• A private right of action keyed to jailbreaking - circumvention of safety controls by third parties - rather than to model output directly.
• Subpoena power actually exercised on 2026-09-28.

After (if enacted - PREDICTION, not fact)

• Any AI model legally marketed or deployed in NYC would need a validated kill switch and a filed certification with the Office of Cyber Command, with the local law effective 180 days after it becomes law.
• Out-of-state vendors face a compliance decision they cannot route around by being headquartered elsewhere, though jurisdiction is contestable.
• Regulatory precedent pressure spreads to other municipalities and to the pending federal preemption fight.

This is the most concrete technical content in the story, and it comes from the introduced bill text itself (Int. 2602, new Subchapter 27 of Chapter 5 of Title 20 of the NYC Administrative Code).

§ 20-883 - Definitions. The bill defines "artificial intelligence model" as "an engineered or machine-based system that varies in its level of autonomy and that can, for explicit or implicit objectives, infer from the input it receives how to generate outputs that can influence physical or virtual environments." It also defines: shut-down capability ("the technical capability for a human operator to cause an artificial intelligence model to temporarily or permanently stop functioning"); third-party validator ("a person, other than an affiliate of a developer of an artificial intelligence model, who is retained, contracted, or otherwise engaged by a developer ... to validate such artificial intelligence model"); plus behavior under distribution shift, breach of security, calibration, data provenance, determinism, holdout data, latency, throughput.

§ 20-884 - The prohibition. It is unlawful to market, offer for sale, sell, or deploy an AI model unless (1) it has been validated by a third-party validator on the § 20-885(a) topics, and (2) it includes a shut-down capability. Both conditions are independent requirements.

§ 20-885(a) - Eight mandatory validation topics. The validator shall assess:

1. Task performance - accuracy, precision and recall, calibration, behavior under distribution shift
2. Determinism - "the ability of an artificial intelligence model to always produce the exact same output when given the exact same input"
3. Latency and throughput
4. Data provenance - "the origins of the data on which an artificial intelligence model is trained and whether such artificial intelligence model was tested based on holdout data"
5. Disparate impact on, or bias against, individuals in protected classes under Chapter 1 of Title 8
6. Whether the model handles data lawfully and securely and adheres to informed consent principles
7. Safety - existence and functionality of the shut-down capability, plus the risk level to human safety, of property damage or loss, and of a breach of security
8. Any other topics the director of the Office of Cyber Command deems relevant

§ 20-885(b) - Certification and conflict disclosure. The validator must file with both the developer and the Office of Cyber Command: whether the model is validated and "accordingly is appropriately positioned for deployment"; and any financial or other interest the validator has in the model or its developer.

§ 20-886 - Rulemaking. The director of the Office of Cyber Command must promulgate rules on additional validation topics, the form and manner of the certification, and qualifications for third-party validators. These rules do not yet exist - the compliance burden is therefore currently undefined.

§ 20-887 - Penalties (the source of the "$25,000 per instance" figure).

• (a) A person violating § 20-884 "is liable for a civil penalty of $25,000, per instance of marketing, offering for sale, sale, or deployment of an unlawful artificial intelligence model."
• (b) A person who falsifies a validation is liable for $25,000, "on a per instance basis."
• (c) Any other violation of the subchapter: up to $25,000.

§ 20-888 - Enforcement. Civil penalties are recoverable in a proceeding before an administrative tribunal within the jurisdiction of the Office of Administrative Trials and Hearings (OATH), with administrative summonses issuable by the Office of Cyber Command or a designated agency. Separately, the Corporation Counsel may bring a civil action to recover penalties, seek injunctive relief, and recover attorneys' fees.

§ 2 - Effective date. "This local law takes effect 180 days after it becomes law."

FACT - the "per instance" phrase, quoted rather than paraphrased. Menin, to Fortune: A $25,000 fine applies to each instance, "which Menin said means that 'if there's a swarm of agents, the penalty would apply per agent.'" The bill text does not define "instance." FACT - this ambiguity is load-bearing: if an agent swarm is the deployment unit, per-instance penalties could scale with fleet size rather than with product count. INTERPRETATION: this is the single most consequential unresolved drafting question in the package.

FACT - the whistleblower bill is separate and unquantified. Int. 2605 (Menin) would let individual whistleblowers receive a portion of fines or penalties recovered. amNewYork reports the Council's announcement "does not say how large a whistleblower's share could be or spell out how the incentive program would work."

FACT. The package is the first US municipal attempt to regulate AI at the point of sale rather than only as a public-sector buyer or employer.

FACT. It is deliberately positioned against a federal record that has moved toward blocking sub-federal action, not toward filling the gap. Fortune documents the DOJ task force suing states and Colorado gutting its own law; the pending Cruz/Klobuchar/Thune bill would likely preempt New York's own RAISE Act.

INTERPRETATION. This produces the structural tension anticipated but sharpened: vendors now face a patchwork of non-uniform sub-federal duties that federal preemption alone cannot dissolve, because a federal preemption bill would have to reach municipal codes, not just state statutes.

INTERPRETATION - the template argument is real but premature. A $25,000 per-instance penalty and a kill-switch mandate are copyable. A validator-qualification regime is not it requires a mature third-party assurance market and a regulator willing to certify auditors. New York City is proposing to build that market by statute. Whether other cities copy the enforceable core or only the headline is the open question.

INDEPENDENT EVIDENCE that the pressure is coordinated across levels: Hoodline reports that under New York's Responsible AI Safety and Education Act (RAISE), major frontier developers must register with the state starting in November and report critical safety incidents within 72 hours beginning 2027-01-01, overseen by a new state Office of Digital Innovation, Governance, Integrity and Trust. That is a different clock and a different threshold from Int. 2601's 24-hour city-contractor reporting window.

--

FACT. Three things that did not exist before 2026-09-25 now formally exist in legislative text:

• A civil penalty for the absence of a kill switch, separate from the absence of validation.
• Joint liability on the validator - an assurance provider can be fined $25,000 per instance for falsifying a validation.
• A private right of action (Int. 2600, Maloney) where a New Yorker harmed by a jailbroken system can sue the AI company if three conditions are met: the harm was foreseeable to the company, the company failed to implement reasonable safeguards, and the harm was caused by a third party who exploited that failure. This routes liability around model output and onto safeguard adequacy.

FACT. Also newly possible: an individual whistleblower can be paid a share of recovered penalties; City employees and contractors gain whistleblower protection for reporting AI public-safety threats (Int. 2604, Riley); and a public, sworn record of frontier-lab testimony before a municipal body.

INTERPRETATION. The validator as a regulated, licensed intermediary is the deepest structural change. It converts AI assurance from an optional marketing claim into a gated occupation, and it creates a standing compliance function that did not previously exist at model vendors.

1. Does "deploy" reach hosted API access from servers outside New York? The discovery aggregator flagged this. It remains the single most consequential unanswered question: it determines whether the bill binds globally-reachable products or only NYC-based deployments and city procurement.
2. What is "an instance"? $25,000 per model, per deployment, per end user, or per agent? Menin told Fortune the per-agent reading applies "if there's a swarm of agents."
3. How large a whistleblower share, and how is it calculated? Int. 2605 gives no formula.
4. What will § 20-886 validator qualifications say? Until they exist, no one can know what a compliant validation looks like.
5. Will any CEO testify, or will the hearing settle for company representatives?
6. Will SpaceXAI comply, and will enforcement go to State Supreme Court?
7. Does Int. 2600 survive a Section 230 challenge? Courts have not settled whether Section 230 covers AI-generated output.
8. Does the Council majority exist? Ten bills, nine sponsors, one Committee of the Whole - a hearing is not a vote, and no floor vote is scheduled.
9. How do the city kill-switch and the state RAISE Act's 72-hour reporting interact? Two clocks, two regulators, different triggers.
10. What did the July incident actually involve? The Council's account is general; the scale figures circulating are secondhand.

FACT - scheduled. The Committee of the Whole hearing convening all 51 Council members is set for 2026-10-05. Int. 2602 is listed on Legistar with committee Committee of the Whole; the Legistar On agenda field reads 10/8/2026, which conflicts with the announced 10/5 date and is flagged in Section 13. A Committee Report 10/5/26 appears among the bill's Legistar attachments.

FACT - pending. SpaceXAI's response to the 2026-09-28 subpoena; identification of which named representatives will testify for Anthropic, OpenAI, Google and Meta.

INTERPRETATION - the near-term sequence:

1. 2026-10-05 hearing. A Committee of the Whole hearing is a hearing, not a floor vote. The realistic output is testimony, public record and political positioning.
2. Witness behaviour is the real signal. The discovery framing - whether CEOs or general counsels appear versus forcing a subpoena fight - is a reasonable read, but the 2026-09-28 escalation has already partly answered it: three firms negotiated to the subpoena deadline and one was compelled.
3. Subpoena enforcement risk. Non-compliance by SpaceXAI would put the Council's first Charter § 29 subpoena against a major lab into State Supreme Court.
4. Drafting is where the story moves. "Instance," validator qualifications, and the "deploy"/API question will determine whether this is a serious regime or an unworkable one.
5. Federal overlay. The Cruz/Klobuchar/Thune preemption bill, if advanced, could moot or narrow the whole package - and would not obviously reach a city administrative code.
6. State overlap. RAISE registration begins in November 2026 with 72-hour critical incident reporting from 2027-01-01, creating a second, parallel clock.

PREDICTION (explicitly labelled): the package is unlikely to pass as introduced. The likeliest near-term outcome is a Committee of the Whole hearing that produces visibility and a narrower, negotiated bill - most plausibly dropping or softening per-instance penalties and "determinism" - while the more administratively tractable items (24-hour contractor reporting, the ban on false safety claims, chatbot privacy, the algorithmic-tools report) advance. Confidence: moderate. This is prediction, not reporting.

INTERPRETATION. The headline detail is the $25,000-per-instance penalty and the kill switch. The genuinely interesting detail is the validator.

New York City is proposing not just to require AI vendors to prove their systems are safe but to license the people who say so, then fine those people per instance if they are wrong. That is a different regulatory object from anything currently in force in the US and it is the part that other cities - and other regulators - would actually have to replicate, because a per-instance fine is copyable in an afternoon while a validator qualification regime takes years to stand up.

Two honest caveats belong in any coverage of this:

• Nothing has passed. These are ten introduced bills across nine sponsors, heard by a Committee of the Whole on October 5. A hearing is not a vote, and the Speaker does not control the Council.
• The date is genuinely in question. The package was unveiled and formally introduced on 2026-09-25, one day before the configured research window opens. The 2026-09-28 subpoena of SpaceXAI and the compelled-testimony commitments from Anthropic, OpenAI, Google and Meta are the events.

The most quotable line in the whole package is Menin's, and it should be quoted rather than paraphrased: on "per instance," she said it means "if there's a swarm of agents, the penalty would apply per agent." That single sentence is why this story is worth more than a routine local-law roundup - it converts a municipal penalty from a cost of doing business into a cost that scales with the size of the agent fleet you ship.

On sourcing. This story entered research on a single aggregator page. It did not need to be skipped. Every load-bearing detail - bill numbers, sponsors, the penalty structure the enforcement mechanism, the effective date, the subpoena authority - is now anchored in the Council's own press releases, the Legistar record, and the introduced statutory text. The one detail attributed to Fortune and I could not confirm - the $25,000-per-instance figure with data-quality/bias/privacy/security validation - is correct, and is in fact stronger than reported: it is § 20-887 of the bill itself, and it extends to the validator.
