This market will resolve to “Yes” if both the following occur:
1. Zohran Mamdani wins the 2025 NYC Mayoral election.
2. The New York City Rent Guidelines Board implements rent adjustments at 0.0 % for both one-year and two-year renewal leases for rent-stabilized apartments citywide by December 31, 2026, 11:59 PM ET.
The policy will be considered implemented only if a 0.0 % increases for both one-year and two-year renewal leases is in effect by the resolution date. An announced intention or proposed order not yet effective will not qualify. Orders that are blocked, enjoined, or otherwise prevented from taking effect by the deadline will not qualify.
If the policy is enacted through another official mechanism, including but not limited to a mayoral executive order, local legislation, or state law, and goes into effect by the resolution date it will qualify.
Orders that apply only to one lease term (e.g., 0 % on one-year but > 0 % on two-year), apply only to specific unit types (e.g., hotels or SROs), or relate to non-stabilized units will not qualify. Policies which include limited exceptions — such as exclusions for specific categories of rent-stabilized units (e.g., hardship exemptions, temporarily exempt buildings, or administrative carveouts) — will still qualify as long as a general policy of 0 % rent adjustment for both one-year and two-year renewal leases on rent-stabilized apartments and lofts is in effect citywide.
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 and official Rent Guidelines Board materials.
