Raymond McKay holds a commanding position in the Republican primary for Rhode Island's U.S. Senate seat, scheduled for September 9, 2026, as traders assign him an 88.5% implied probability. McKay has sustained active campaigning focused on the Senate race, including consistent fundraising efforts that reflect stronger organizational infrastructure within the state party. In contrast, Allen Waters has redirected his efforts toward an independent bid for Providence mayor, reducing his visibility and resources in the Senate contest. This shift, combined with limited polling data and the absence of major recent endorsements or debates, has reinforced trader consensus around McKay's frontrunner status while leaving room for late developments closer to the primary date.
