A freeze on one lease term, an announcement awaiting implementation or a measure confined to other property types can miss the test. The contract requires Mamdani to win the specified 2025 mayoral election and a citywide policy of zero increases for both one-year and two-year rent-stabilized renewal leases to be effective by the deadline.

The event had $289,969 in cumulative volume. These are a dated price snapshot and event-wide turnover, respectively. [1](https://polymarket.com/event/will-mamdani-freeze-nyc-rents-before-2027)[2](https://polymarket.com/event/will-mamdani-freeze-nyc-rents-before-2027/will-mamdani-freeze-nyc-rents-before-2027) The quoted Yes probability describes this specific contract at retrieval time; it is not an official determination that the condition occurred. [1](https://polymarket.com/event/will-mamdani-freeze-nyc-rents-before-2027)[2](https://polymarket.com/event/will-mamdani-freeze-nyc-rents-before-2027/will-mamdani-freeze-nyc-rents-before-2027) The API reported event-level liquidity of $2,407 at retrieval. That aggregate does not establish the executable depth or spread of this individual position.

Readers must also distinguish rent-stabilized renewals from every rent paid in New York City. The useful checks are the effective rent guidelines board order; both renewal-term percentages. Those checks connect the public story to the settlement condition instead of treating attention as confirmation.

The mayoral-election condition refers to 2025 and must be checked separately. [2](https://polymarket.com/event/will-mamdani-freeze-nyc-rents-before-2027/will-mamdani-freeze-nyc-rents-before-2027) Freezing one-year leases while increasing two-year leases does not qualify. That detail narrows the question being priced and is worth checking before comparing this contract with a broader political prediction.
