This market will resolve according to the candidate who wins the nomination for the Republican Party to contest the FL-19 congressional district seat in the U.S. House of Representatives in the 2026 midterm elections. The Republican primary will take place on August 18, 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 Republican sources, including https://www.rnc.org/. Any replacement of the nominee before election day will not change the resolution of the market.Catalina Lauf leads the Polymarket odds in the crowded August 18, 2026, Republican primary for Florida’s open 19th congressional district after incumbent Byron Donalds entered the gubernatorial race. Her 52% share reflects trader emphasis on her local residency in Bonita Springs, small-dollar fundraising momentum exceeding $400,000 in early quarters, and background as a former Trump administration official. Jim Oberweis sits second at 17.7% on the strength of substantial self-funding that has produced the highest total receipts, though much derives from personal loans. Jim Schwartzel’s 11.3% position tracks his sizable cash-on-hand from prior business success. Lower probabilities for Madison Cawthorn and others align with their more limited recent in-district organization following the June qualification deadline. Traders are pricing the fragmented field ahead of the primary.
