**A Song To Sing** leads CMA Musical Event of the Year trader sentiment at 41.5% implied probability, driven by the star power of Miranda Lambert and Chris Stapleton, whose first official duet blends strong songwriting pedigree with proven CMA appeal and solid radio traction since its 2025 release. Ella Langley and Morgan Wallen’s **I Can’t Love You Anymore** follows at 32%, benefiting from Langley’s dominant nine-nomination campaign and rising profile, though it trails in perceived vocal-event prestige. The remaining nominees—Kacey Musgraves and Lambert’s **Horses and Divorces**, Carly Pearce and Riley Green’s collaboration, and the all-star **McArthur**—sit in single digits, reflecting limited momentum. With CMA voting underway through late October and the November 18 ceremony approaching, traders are weighing historical preference for high-profile pairings against Langley’s broader industry surge in a tightly contested field.
