📈 New York City mayor election betting odds
Curious who the favorite is to become New York City's next mayor? Market-based platforms like Kalshi offer valuable insight:
Mamdani has surged past Cuomo after a dominant debate performance and endorsements from progressive leaders. Cuomo’s odds have fallen from 70% in early June to 5%, reflecting concerns over a potential independent run and weak ranked-choice positioning.
Mamdani’s rise
Backed by Alexandria Ocasio-Cortez and Bernie Sanders, Mamdani’s progressive agenda—housing reform, free childcare, and transit expansion—has energized younger voters. His campaign has been strategic about ranked-choice voting (RCV), ensuring second- and third-choice support. His odds are buoyed by progressive momentum and effective ranked-choice strategy.
Cuomo’s decline
Despite big-name backing and financial muscle (Bloomberg’s PAC contributed over $8 million), Cuomo’s comeback bid has been marred by lingering controversies. While still a viable candidate, Kalshi users now see his path narrowing without cross-ideological support.
The former Governor is betting on name recognition and centrist appeal. Yet with scandal baggage and a primary loss looming, some speculate he may continue as an independent. That uncertainty weakens his odds.
Other candidates
Republican Curtis Sliwa, Independent Eric Adams, and reform lawyer Jim Walden round out the field, but all are long shots in heavily Democratic NYC.
What is ranked-choice voting?
New York uses ranked-choice voting, allowing voters to rank up to five candidates. If no one earns over 50% of first-choice votes, the lowest candidate is eliminated, and ballots are redistributed based on the next preference. This continues until someone clears 50%.
Given NYC’s Democratic tilt, the winner of the primary often becomes the mayor, making June’s vote arguably more critical than November’s.
Betting tips
Betting on politics isn’t just about picking a favorite—it’s about understanding momentum, mechanics, and timing. The 2025 NYC mayoral race is shaped not only by personalities and policies, but also by the quirks of ranked-choice voting and the behavior of informed bettors.
