Voters are heading to the polls in New York, with four competitive races in Democratic congressional primaries in focus.

TL;DR
- Traders on prediction market platform Kalshi expect Mayor Zohran Mamdani's endorsed candidates to win two out of three competitive Democratic congressional primaries in New York City.
- Brad Lander (NY-10) and Claire Valdez (NY-7) are favored to win their races, while Darializa Avila Chevalier (NY-13) is considered an underdog.
- In the NY-12th district, where Mamdani did not endorse, traders see state Assemblymember Alex Bores as an underdog due to significant spending for and against him related to AI regulation positions.
