Rep. Julia Letlow leads Polymarket trader consensus at 77% implied probability to win Louisiana's Republican U.S. Senate primary on May 16, reflecting her surge in late polls like Quantus Insights (May 6-7), where she captured 40% support among likely voters amid a three-way race with Treasurer John Fleming (28%) and incumbent Sen. Bill Cassidy (18%). Letlow's momentum stems from President Trump's January endorsement, backing from Gov. Jeff Landry and AG Liz Murrill, and a strong May 5 debate performance emphasizing conservative credentials over rivals. Cassidy's support has eroded due to his 2021 Trump conviction vote and criticism from activists like Scott Presler, while Fleming trails after recent rescinding of state GOP endorsements. With early voting concluded and turnout pivotal in this closed primary, odds highlight Letlow's path to avoid a runoff.

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.
