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.Trader consensus heavily favors former NYC Comptroller Brad Lander at 84% implied probability to win the NY-10 Democratic primary on June 23, driven by private polling from both campaigns showing him with a sizable lead in recent weeks, bolstered by endorsements from Mayor Zohran Mamdani, Sen. Elizabeth Warren, and powerful union 32BJ SEIU. Incumbent Rep. Dan Goldman holds 16% amid aggressive self-funding of at least $1 million announced last week, alongside strong first-quarter fundraising, but faces headwinds in a district that swung progressive in the recent mayoral race. Minor candidates like City Councilmember Alexa Avilés trail due to limited visibility and resources, with the race's outcome hinging on turnout among key voting blocs in Brooklyn and Lower Manhattan.
