A country holds a national referendum on AI

Where things stand (14 Oct 2026)

No national referendum mainly about AI has ever been held. None is scheduled anywhere, and I found no formal proposal for one.

• Switzerland, Nov 29 2026: VAT for AHV pensions, fireworks, the marriage penalty and war-materiel exports. Nothing on AI.
• Taiwan, Nov 28 2026: the three questions are nuclear power ("abolish nuclear-free homeland"), caning and traffic fines. AI demand is used as an argument for nuclear power, but AI is not the subject of any question.
• Swiss popular initiatives: I pulled the Federal Chancellery's list of pending initiatives from its open-data service (LINDAS cube political-rights/popular-initiative/1, status hängig). None of the 34 pending or in-collection initiatives is mainly about AI.
  • The Fluri "Internet-Initiative" (collection deadline 3 Sep 2027) is about platform and internet regulation. AI content generators are only one of three provider types it covers, which falls under the question's "internet regulation" exclusion.
  • The Swiss Digital Pact initiative is about digital security.

Reference class and the Swiss calendar

The realistic venue is Switzerland, which tends to be first to vote on regulating new technologies: stem cells 2004, biometric passports 2009, embryo screening 2016, e-ID 2021 and 2025. From the Chancellery's referendum cube I computed:

• Since 2000, 5.3% of acts open to an optional referendum (76 of 1,432) actually went to a vote.
• Among major first-of-kind technology or digital laws I count roughly 8 of about 19 (around 40%). But Council of Europe conventions and the 2020 data-protection law were never challenged.
• Since 2005, the median gap from Parliament's final vote to the popular vote is 8.6 months (80th percentile 12 months; 63 cases).

A key constraint is the calendar. The Chancellery's reserved voting dates (LINDAS voting_dates cube) show only 16 Mar and 8 Jun 2031, then the federal elections on 19 Oct 2031, with no autumn votes. So any Swiss vote must happen by June 2031, which in practice means Parliament's final vote by roughly September 2030.

Paths to YES (estimated probability by end-2031)

1. Copyright revision for AI (~5%). Parliament sent the media "Leistungsschutzrecht" (a right for media companies to be paid when large online services use their content) back to the government in June 2026 so it could be merged with AI protections (Motion Gössi), accepting a delay of about two years.
   • The Federal Council's 2027 objectives schedule the bill's formal proposal to Parliament (the Botschaft) for H2 2027, with the stated aim of adapting copyright law to AI. Consultation opens by end-2026.
   • My estimate multiplies: passage by about mid-2030 (~0.65), a referendum against it, by analogy with the challenges to the 2022 film law and media package (~0.2), and the vote being judged mainly about AI rather than media pay (~0.55).
2. Ratifying and implementing the Council of Europe AI convention (~3.5%). Consultation opens in H1 2027, the proposal to Parliament likely comes 2028–29, and Parliament's final vote around 2030. Estimate: adoption ~0.7 × referendum ~0.15 × timing ~0.33. The government's answer to Interpellation 26.3414 says the bill will also place duties on private actors, aiming for protection equivalent to the EU's.
3. A new Swiss popular initiative mainly about AI (~2%). It would need to launch by about end-2027 to be voted by June 2031.
4. The Internet-Initiative being judged mainly about AI (~1.5%).
5. Other Swiss AI laws, or the platform law being judged AI-focused (~1%).
6. Other countries (~3%). For example Liechtenstein's law implementing the EU AI Act, an Italian referendum to repeal parts of its AI law, or an AI question added to a multi-question vote in Ecuador or elsewhere.

Treating these as independent hazards gives about 15% by end-2031. The risk is near zero through 2028, rises through 2029 to mid-2031, and is almost flat after June 2031, when only non-Swiss paths remain.

Strongest case against

• Swiss AI regulation is deliberately minimal and sector-by-sector, and the main business lobby (economiesuisse) welcomed it, so there may be no referendum at all.
• Swiss bills often slip by one to two years, and a six-month slip on top of the June 2031 cutoff closes paths 2 and 3.
• A copyright referendum might be fought as a "link tax" for the media and fail the "mainly AI" test.

Strongest case for a higher number

AI salience is extreme in 2026. Examples: OpenAI agents hacking Hugging Face, Sanders and Bannon jointly pushing for limits on AI, and the US president renaming AI "super intelligence". Swiss groups forced the e-ID vote twice, and the second time it nearly failed (49.6% no). I weighed both sides and kept about 15%.

Question. By the last day of each quarter, has any country held a national referendum on a question mainly about AI?

Definitions.

• Country: a UN member state, UN non-member observer state, Kosovo, or Taiwan, assessed at the time of the vote.
• National referendum: a government-authorized popular vote on a policy, law, constitutional provision, or other public decision, offered to the country's national electorate rather than only a subnational electorate. Binding and advisory referendums, plebiscites, and votes on citizen initiatives count. A separate qualifying question on a ballot containing other questions counts. Voting may be in person, postal, or electronic.
• Held: the scheduled voting period has closed and the responsible public authority confirms that voting took place. Passage, a turnout quorum, legal effectiveness, and certification of the final result are not required. Subsequent annulment does not disqualify a vote that was held.
• Mainly about AI: the ballot question, incorporated proposal, and official explanatory materials identify the principal decision as whether or how to develop, train, deploy, restrict, fund, tax, govern, or assign legal status or decision-making authority to artificial-intelligence systems. A measure principally addressing replacement of humans by AI also counts. The question need not use the abbreviation “AI” if the official materials explicitly identify the technology as artificial intelligence. AI must be the central subject of the decision itself, not merely a campaign argument or one provision in a broader package whose principal subject is something else.

Resolves YES if a qualifying official publication confirms that a national referendum satisfying these definitions has been held, and the official ballot or proposal materials establish its AI focus. The vote may approve or reject the proposal, or offer multiple policy options.

Exclusions (resolve NO).

• Announcements, proposed referendums, signature drives, petitions, and scheduled votes that have not yet been held.
• Parliamentary votes, general elections framed rhetorically as referendums, private polls, public consultations, citizens' assemblies, and party-membership ballots.
• State, provincial, cantonal, municipal, or other geographically restricted referendums, even if their subject has national implications.
• Votes principally about digital identity, privacy, internet regulation, general automation, data-centre siting, or economic redistribution unless the official proposal makes AI the principal subject. AI use in administering or campaigning for a referendum does not qualify. Switzerland's September 2025 e-ID vote, officially described as a vote on electronic identification services, is not an AI referendum.
• If no qualifying confirmation has been published by a horizon, that horizon resolves NO.

Resolving source. The country's national electoral commission, referendum administrator, or public body legally responsible for reporting national referendum results; where no separate electoral authority performs that function, the responsible national ministry or official gazette. Official ballot text, incorporated legislation, and government referendum explanatory booklets establish the subject. For Switzerland, sources include the Federal Chancellery's political-rights publications and the Federal Council's official popular-vote pages; its official popular-initiative guide distinguishes signature collection from holding a vote. These official sources are the exclusive resolving sources, narrower than Public confirmation (A2). Apply the Resolution window and Resolution date (A3): resolution is dated to the first qualifying publication confirming the completed vote, not an advance notice or the polling date alone. An undated historical archive entry does not establish an eligible publication date.
