Who starts at QB for Kansas City in Week 1?
There's a chance that Kansas City may begin the 2026 pro football season with a new starting quarterback for the first time since 2017. Patrick Mahomes, two- time most valuable player was injured late in the 2025 in a Week 15 loss to Los Angeles, where he tore his ACL and LCL in his left knee. Mahomes opted to have surgery immediately the next day in order to better his chances to be ready to play in Week 1.
Kalshi now lists Mahomes ($0.91) as a frontrunner to start and he has plenty of incentive to play the first week in a key AFC West showdown. Denver claimed the top seed in the AFC last season and swept the season series against Kansas City. As a safeguard, Kansas City picked up Justin Fields as a backup quarterback. He has expressed interest in learning from the three-time champion. Fields ($0.12) could also be used in action for hybrid roles and emergency snaps this season according to head coach Andy Reid.
Patrick Mahomes has a 6-2 career record in Week 1 games as a starting quarterback for Kansas City dating back to 2018. If Kansas City wants to challenge Denver for the AFC West, they may need to start off their season with their best player under center. Justin Fields, on the other hand, is aiming to improve his 2-3 career record and start for his fourth different NFL team in Week 1. Fields has won two of his last three opening-week starts with the Steelers in 2024 and the Bears in 2023.
