Will Mamdani freeze NYC rents before 2027?

Updated 2d ago

How to read the numbers

Implied / market-implied YES

The probability of YES implied by current traded prices (mid or last). It is what participants are paying for, not a claim about real-world odds.

Model estimate

A rule-based heuristic from the signal engine when a rule sets one, not a black-box forecast. Some signals only describe liquidity or spreads and may show no model estimate.

Edge / gap

The difference between the model estimate and market-implied, in percentage points (model minus market for YES). Filters may use “largest gap.” This is informational only-not trading advice or guaranteed advantage.

Stance (above / below / near estimate)

Compares market-implied to the model estimate when both exist. Labels are not buy or sell recommendations.

Confidence

A simple UI clarity label for signals (not a prediction). It summarizes the signal’s own magnitude/quality metrics into one of: Low, Mid-low, Mid, Mid-high, or High.

Volume

Reported trading activity for the market, for context on size and liquidity.

Change & sparklines

Movement in market-implied YES over the window labeled on the card-often 24h where data allows.

Signals

Rule-based flags from ingested public data. They are not trade recommendations.

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.
