Darializa Avila Chevalier leads trader consensus in the New York 13th District Democratic primary, scheduled for June 23, as a democratic socialist challenger backed by Mayor Zohran Mamdani and aligned with progressive priorities on housing, campaign finance, and foreign policy. Incumbent Adriano Espaillat, a five-term representative, draws support from House Democratic leadership and traditional institutional networks while defending his record amid criticism of establishment ties. Recent candidate forums and debates have highlighted contrasts on issues such as immigration enforcement and donor influence, sharpening focus on Harlem and Upper Manhattan voters. Minor candidates remain negligible in the market. The 61.5% implied probability for Chevalier reflects the wisdom of crowds assessing the strength of this primary challenge relative to the incumbent's base in the final weeks before ballots are cast.
