Morgan Wallen’s dominant 2026 chart run, including a fourth Country Airplay No. 1 with “Been By Now” and continued strong streaming and sales for his 2025 album *I’m the Problem*, has driven trader consensus toward his 77.4% implied probability for Billboard’s year-end top artist. He has now posted at least four radio leaders in each of the past three years, a first in the format, while placing multiple titles on the Hot 100. Other contenders trail far behind: Kendrick Lamar, Taylor Swift, and Post Malone sit in single digits amid more fragmented pop and hip-hop releases, with no artist matching Wallen’s consistent volume or crossover airplay. Year-end rankings will incorporate final streaming, sales, and radio data through December, but Wallen’s current trajectory leaves limited room for a late surge by competitors.
