The race for the Democratic nomination for New York City mayor has seen fluctuating odds between Andrew Cuomo and Zohran Mamdani according to Polymarket data. Initially, Mamdani held a strong lead with 55% to Cuomo's 45%, and at one point, Mamdani's odds surged to as high as 91% while Cuomo's dropped to 9%. However, by late June 2025, Cuomo began gaining ground, with his support rising to 57% against Mamdani's 43%. Despite Cuomo's resurgence, Mamdani maintained a leading position in overall mayoral election odds at 68%, followed by incumbent Eric Adams at 19% and Cuomo at 10%. Recent trends indicate Cuomo's increasing support as Adams' popularity declines. Discussions have emerged suggesting that if Cuomo were to drop out, it could improve Adams' chances of winning and prevent Mamdani, described as a socialist candidate, from securing the mayoralty. Calls for Cuomo and Republican Curtis Sliwa to clear the field for Adams have been noted amid concerns over Mamdani's rising odds, which reached 70% on Polymarket at one point.
