Spencer Pratt hits 33% on Kalshi as L.A. mayoral race draws volume
Former reality TV personality Spencer Pratt has surged to second-favorite status in Kalshi trading for the Los Angeles mayoral race, with traders pricing him at 33% to win as of May 20 while incumbent Karen Bass remains the favorite at 64% ahead of the November election. Pratt is dominating trading volume on the regulated exchange for the contest. Separately, a Kalshi market prices the odds that former President Trump will endorse Pratt's campaign at 35%, with other potential endorsers including Greene at 40% and Bannon at 26%. The unlikely candidacy has drawn significant prediction-market activity to the regulated platform.
Kalshi's official X account now treats price-point milestones as breaking news events. Any CFTC review of that practice could rewrite how regulated exchanges broadcast live odds, especially after this visible political market surge.
Pratt's mayoral pricing becomes the latest in a string of headline Kalshi political markets — alongside Massie's Kentucky collapse, Talarico's Texas flip, and the KY-04 arbitrage spread against Polymarket — showing the exchange's political contracts driving both trading volume and regulatory scrutiny.
