Canonical status

Source status (Polymarket)

active · closed · uma=resolved

Derived status (Orrery)

RESOLVED NO

Reason

Upstream marked the market closed/settled with NO price dominant.

The derived status is computed from the source flags plus the live YES price, so a market trading near a rail can read as PRICE-PINNED while upstream is still active. That isn't the same as resolved.

Market Description

Zohran Mamdani has proposed creating city owned grocery stores to combat rising prices (see: https://www.nytimes.com/2024/12/12/nyregion/grocery-stores-city-owned.html). This market will resolve to “Yes” if both the following occur: 1. Zohran Mamdani wins the 2025 NYC Mayoral election. 2. The City of New York implements a policy under which at least one grocery store that is city-owned and operated is actively open to the public by June 30, 2026, 11:59 PM ET. The policy will be considered to have been implemented if at least one such store is open for regular grocery retail sales to the public by the resolution date. The enactment or announcement of a policy without an operational, open store will not alone qualify. Policies that are blocked, cancelled, or not yet in effect by the resolution date will similarly not qualify. Limited pilots, studies, planning initiatives, or temporary pop-up markets which don’t regularly operate as regular grocery stores do not qualify. Partnerships which include partial city ownership will qualify as long as the store is substantively under City of New York control. Partnerships with non-profit or other operators which don’t include direct city ownership of the store will not qualify. Only stores that are initiated, approved, or opened during Zohran Mamdani’s mayoralty and that are described in credible reporting or official City communications as part of the “city-owned grocery store” initiative associated with his campaign platform will qualify. Grocery stores created by previous or subsequent administrations, or any other government-run or subsidized retail programs that are not reasonably attributable to the Mamdani administration’s city-owned grocery store policy, will not qualify. If Mamdani is confirmed to have lost the 2025 NYC Mayoral election by a consensus of credible reporting, this market will immediately resolve to “No.” The resolution source for this market will be a consensus of credible reporting.
