Resolution criteria on PolyGram: The 2026 Pompei, Italy mayoral runoff election is currently scheduled to be held on June 7 and 8, 2026. This market will resolve according to the candidate who becomes the next mayor of Pompei as a result of this election.

If the result of this election isn't known by April 30, 2027, 11:59 PM ET, the market will resolve to "Other". The primary resolution source for this market will be a consensus of credible reporting; however, if there is any ambiguity in the results, this market will resolve according to official information from Pompei.

Pompei, the archaeological site near Naples, will hold a mayoral runoff election on 7–8 June 2026. The settlement window closes on 8 June at 06:00 UTC, with resolution dependent on credible reporting of the elected candidate. The market currently implies a 33% probability for the unnamed YES outcome, reflecting substantial uncertainty about the eventual winner. Polymarket's order book is pricing this as a competitive race, with the 33% figure suggesting the YES candidate faces material headwinds against alternatives.
Italian municipal elections typically see turnout between 50–65%, with runoff dynamics often favouring incumbents or candidates with consolidated local support. Comparable Campania region mayoral contests have shown that second-round results frequently diverge from first-round vote shares, particularly when fragmented first rounds force coalition-building. The current implied probability sits below the 50% threshold, suggesting traders view the YES candidate as the weaker position in a two-candidate runoff scenario.
Key catalysts include any formal candidate declarations or withdrawals before the election, local campaign developments reported by Italian media, and turnout patterns in the days preceding the vote. The resolution mechanism includes a potential second round, with a fallback to "Other" if results remain unclear by 30 April 2027. Traders should monitor announcements from Pompei's municipal administration and regional Italian news sources for shifts in candidate positioning or electoral logistics that might affect the probability distribution across the order book.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a two-hour dispute window opens, and if no one stakes a counter-claim the payout is final. Contested outcomes escalate to UMA token-holder voting. Payouts clear in USDC to the winning side.
