This market will resolve according to the candidate who wins the nomination for the Democratic Party to contest the NY-10 congressional district seat in the U.S. House of Representatives in the 2026 midterm elections. The Democratic primary will take place on June 23, 2026. If no nominee is announced by November 3, 2026, 11:59PM ET, this market will resolve to "Other". The resolution source for this market will be a consensus of official Democrat sources, including https://democrats.org/. Any replacement of the nominee before election day will not change the resolution of the market.**Brad Lander commands 83.5% trader consensus to win the NY-10 Democratic primary on June 23, driven by robust progressive endorsements and the district's left-leaning electorate, as shown in 2025 mayoral results where allies like Mayor Zohran Mamdani dominated locally.** Recent developments include 32BJ SEIU's April 2 endorsement, Sen. Elizabeth Warren's April 24 rally appearance, and Lander's April 10 call to halt U.S. aid to Israel including Iron Dome funding—contrasting incumbent Dan Goldman's support for conditioned defensive aid—which energize key voting blocs. Despite Goldman's April 23 pledge of $1 million-plus in personal funds, Q1 fundraising edge, and backing from Gov. Kathy Hochul and Rep. Hakeem Jeffries, traders view Lander's longstanding City Council tenure and grassroots strength as decisive, though late spending or turnout could shift dynamics.
