NYC Democratic Primary Races Draw Close Watch From Prediction Markets
Traders on prediction markets are betting on Mamdani-backed candidates to win in key New York City Democratic congressional primaries.
New York City voters are casting ballots in a set of competitive Democratic congressional primaries, with political forecasters and prediction market traders paying particularly close attention to four races seen as bellwethers for the direction of the city's progressive movement.
