Mamdani’s dominance only grows in hypothetical four-way matchups. Without Cuomo in the race, he climbs to 55 percent; without Adams, he rises to 51 percent. Even in direct, one-on-one contests, Mamdani maintains a decisive edge: 52 percent to Cuomo’s 40 percent, and 59 percent to Adams’s 32 percent.

Mamdani is leading his major opponents beyond the margin of error in what is the largest NYC mayoral polling sample size to date.

A once-commanding lead for Democratic nominee Zohran Mamdani in the New York City mayoral prediction markets has narrowed significantly.
