Trader consensus strongly favors Rep. Julia Letlow to win Louisiana's Republican U.S. Senate primary for the open seat, driven by her commanding early polling leads—often exceeding 50%—superior fundraising exceeding $1 million, and incumbency from her safe House district. Sen. Bill Cassidy's October 2024 retirement announcement triggered the contest, with Letlow announcing candidacy the next day and quickly consolidating establishment support. Former Rep. John Fleming holds second place via his state treasurer experience and appeal to Trump-aligned voters, while Cassidy lingers at low odds on doubts he stays retired. Minor candidates trail amid a clear frontrunner dynamic ahead of candidate filing deadlines.

If no 2026 Louisiana Republican Senate Primary takes place, this market will resolve to “Other.”
The resolution source for this market will be the first announcement of the results from the Louisiana Republican Party; however an overwhelming consensus of credible reporting may suffice.
