An AI is given formal authority over a city or zone

Where things stand (16 October 2026)

I found no government instrument anywhere that gives an AI system binding, general authority over the administration of a city, district or zone. I also found none in preparation. Every project billed as an "AI city", "AI mayor" or "AI-native government" either leaves humans formally in charge or falls under one of the question's exclusions:

• UAE. On 23 April 2026 the federal cabinet set a target of moving 50% of federal government sectors and services to "agentic AI for autonomous execution and decision-making" within two years (Dubai Media Office, 23 Apr 2026). This applies to federal services, not to any designated territory. Abu Dhabi's "AI-native government" programme says it keeps "judgment and accountability" with officials (ITP.net, Oct 2026). The Dubai International Financial Centre's "AI-native" plan registers AI agents as participants in financial activity, not as municipal authorities (Fast Company ME, Apr 2026).
• China. National rules on AI agents issued 8 May 2026 say users keep "the final decision right". They describe AI in government approvals as an assistant only (CAC, 8 May 2026). Zhenglu town in Changzhou (about 100,000 people) has an "AI town head" that sends tasks to staff across 12 modules. Officials there say it "is not a leader, it is an assistant" (People's Daily Jiangsu, 23 Sep 2026). That makes it an excluded smart-city platform with no formal grant of authority.
• Kazakhstan. Alatau has a special legal regime and is billed as an "AI-native city". The local council and akimat (city administration) still run day-to-day affairs, and AI is described as a tool for decisions (Astana Times, 27 May 2026; KazBuild, Sep 2026). Kazakhstan's national AI law requires human control.
• South Korea. The K-AI City strategy amends the law by 2027 and builds pilot cities by 2030 (Chosunbiz, 9 Sep 2026). It is about infrastructure and services, which the question excludes.
• Albania. A year after Diella was named "AI minister", its role is still unclear. The AI procurement system is only at the tender-specification stage (BIRN, 14 Aug 2026). It is national and covers one function in any case.
• Other "AI mayors". Büttelborn (Germany) and Ratiboř (Czechia) have information chatbots. Japan's AI Party candidates have lost every executive race. Sensay Island is an unrecognised micronation whose population is one groundskeeper (RNZ/CNN, May 2026). None of these qualify.

Base rate and approach

This has never happened. The nearest precedents are stunts with no legal force, such as Albania's AI minister and Japan's AI candidates. So I estimate how likely each type of actor is to cross a strict line. The line is an official instrument giving an AI general executive or coordinating authority, with decisions taking effect without case-by-case human sign-off, in a territory of at least 10,000 people, confirmed by official publications. My rough guess is that a 25–40% chance of some "AI-run city/district" announcement by 2031 shrinks to roughly 5–8% once all the criteria apply. The main routes are:

• a Gulf emirate piloting an AI-run district (about 2–4%);
• a Chinese locality formalising an AI agent's autonomous authority across several functions (about 1–2%);
• an attention-seeking or AI-enthusiastic government such as Albania, Kazakhstan or El Salvador (about 1–2%);
• the US, EU or Japan (under 1%).

Hazard shape (computed)

Quarterly hazards rise from 0.07% in Q4 2026 to 0.16% by late 2027, 0.28% by late 2028, 0.37% by late 2029, 0.46% by late 2030 and 0.54% by late 2031. Cumulative p = 1 − ∏(1 − h), giving about 0.6% by end-2027, 1.6% by end-2028, 2.9% by end-2029, 4.6% by end-2030 and 6.5% by end-2031. The near term is close to zero because nothing is in the pipeline, and an instrument, its commencement and official population evidence would all have to appear. The hazard rises later as AI agents become more reliable and the UAE's two-year push (to about April 2028) and Korea's 2030 pilot cities mature.

Strongest case against my estimate

For a higher number: AI is moving fast. The UAE is explicitly targeting autonomous AI decision-making. AI-city programmes are multiplying (Korea's top development level is an "autonomous city", and Alatau allows experimental legal regimes for AI). There are thousands of jurisdictions, and a "world first" brings publicity. If AI agents become clearly better than humans at administration by 2029, a time-limited pilot (which the question counts) could follow quickly.

For a lower number: In 2026 every leading adopter publicly insists on human accountability: the UAE, China, Kazakhstan, Singapore and the EU AI Act. Even Albania's stunt has no legal substance. The 10,000-resident threshold rules out new planned zones and small villages.

I weigh these at about 6–7% for the full five years.

Question. By the last day of each quarter, has any government designated a city, district, or zone with at least 10,000 residents in which an AI system is given formal authority over municipal administration?

Definitions.

• Government: a national, regional, or local public authority exercising governmental jurisdiction over the territory concerned. A private developer or zone operator counts only when its delegation of governmental powers is established by a qualifying government instrument.
• City, district, or zone: a geographically bounded territory identified in the instrument, including an existing municipality, a newly created administrative district, or a special administrative or economic zone. It need not have elected local government. Unrelated territories cannot be aggregated unless the instrument establishes them as one administrative jurisdiction.
• At least 10,000 residents: at least 10,000 people ordinarily living within the designated boundaries when the grant of authority takes effect. Use the latest official census, population register, or government population estimate applicable to those boundaries and dated no later than that effective date. A contemporaneous official population statement in the establishing instrument also counts. Planned population, housing capacity, commuters, and visitors do not count. If official figures give a range, its lower bound must be at least 10,000.
• AI system: an identified computational system employing machine learning or other AI inference to determine administrative decisions, rather than merely transmitting human decisions or executing fixed administrative rules. No particular developer, model architecture, or legal personhood is required.
• Formal authority over municipal administration: a legally operative grant of general executive or coordinating authority over the territory's local civil administration, extending across multiple municipal functions. The system must be authorized to make decisions that take administrative effect without a human's case-by-case approval, such as binding directions to municipal departments or decisions allocating municipal resources. Human supervision, appeal, override, or the government's ability to revoke the delegation does not disqualify it. Delegation confined to a single specialized service or department is not general municipal authority.

Resolves YES if a published law, decree, charter, ordinance, regulation, or other binding governmental delegation instrument establishes the designated territory and grants the AI system the authority defined above, the grant has taken effect by the quarter-end, and the population threshold is documented. An existing territory receiving a new designation or administrative arrangement counts; creation of a new city is not required. A legally operative, time-limited pilot counts if it satisfies all conditions.

Exclusions (resolve NO).

• Proposed legislation, political pledges, memoranda of understanding, procurement contracts alone, or announcements of future AI-led cities without an operative grant of authority.
• Advisory AI, honorary AI mayors, human officials promising to follow AI recommendations, or systems whose decisions require a human's approval before taking effect.
• Smart-city platforms, traffic control, utility optimization, automated application processing, or procurement systems without the general administrative mandate defined above.
• Private management of a development without delegated governmental authority, simulated cities, and unpopulated or under-threshold planned settlements.
• Broad commitments to digitization, automation, or “AI-native government” without the requisite delegation. For example, the Abu Dhabi Government Digital Strategy 2025–2027 announcement and Dubai AI Lab initiative do not by themselves establish such authority.

Resolving source. The establishing instrument as published in the issuing government's official gazette, legislative register, or official government website; any necessary commencement instrument must also be official. Population evidence must come from the responsible national statistical agency, population registry, or government responsible for the territory. These are narrower source requirements than Public confirmation (A2); press coverage, vendor claims, and evaluator reports alone cannot resolve YES. Apply the Resolution window and Resolution date (A3): a qualifying official publication on or after the opening date must establish or confirm that the operative arrangement and population conditions are met. Where several publications are needed, use the publication date of the last necessary evidence; a future-effective grant requires an official publication on or after commencement confirming it is operative. A later repeal does not undo an earlier YES.
