Claire Valdez leads the NY-07 Democratic primary with an 80% implied probability, driven by recent endorsements including from Mayor Zohran Mamdani, stronger fundraising, and positive early voting reports just days before the June 23 contest. A May Emerson poll showed her narrowly ahead of Brooklyn Borough President Antonio Reynoso at 23% to 21% with 43% undecided, but trader pricing reflects her consolidation of support among younger voters and progressive networks in the district. Reynoso holds steady backing in parts of Brooklyn but trails significantly. Other candidates including Julie Won remain at negligible levels following the June 3 debate among the top three contenders. The compressed timeline leaves limited room for major shifts absent late developments.
