When and where do the Broncos play the Chiefs in Week 1 of the 2026 season?

Kickoff is Monday, Sept. 14 at 8:15 p.m. ET at GEHA Field at Arrowhead Stadium in Kansas City.

Who is favored to win the Broncos vs. Chiefs season opener?

Kansas City enters as a slight favorite after a stunning fall from grace. The Chiefs went 6-11 in 2025, missing the playoffs for the first time since 2014, as quarterback Patrick Mahomes tore his ACL and LCL in Week 15. Mahomes has since been cleared and is listed without an injury designation, and he is expected to start Monday night wearing a knee brace in his first game back.

Denver enters off the best season of the Sean Payton era. The Broncos went 14-3 in 2025, won the AFC West, and reached the AFC Championship Game before falling to New England, a game they played without quarterback Bo Nix after he fractured his ankle in the divisional-round win over Buffalo. Nix underwent surgery on the ankle this offseason and says he is fully healed; the team also traded for Dolphins receiver Jaylen Waddle this offseason.

Kalshi Power rankings

According to Kalshi's 2026 NFL market-implied power rankings, the Chiefs enter as the No. 5 team in the league with a Power Score of 35.7 and a 63% playoff qualification price, while the Broncos rank ninth with a Power Score of 35.1 and a 61% playoff price, a 4-spot gap heading into Denver's Week 1 trip to Kansas City.

What is the projected point total?

Kalshi traders have the game going over 43.5 combined points at 47%.

What is the biggest storyline in the Broncos vs. Chiefs season opener?

Both starting quarterbacks are coming off major injuries. Mahomes is working back from a torn ACL and LCL, while Nix is returning from a fractured ankle that knocked him out of last year's AFC Championship Game. How each holds up physically is the swing factor for this rivalry's first meeting of 2026.

What are the Broncos' and Chiefs' expectations entering the 2026 season?

Broncos: Denver finished 14-3 in 2025, won the AFC West, and advanced to the AFC Championship Game for the first time since winning Super Bowl 50, only to lose that game without an injured Bo Nix. A healthy Nix and the addition of Jaylen Waddle are the swing factors for another deep run in 2026.

Chiefs: Kansas City finished 6-11 in 2025, missing the playoffs for the first time in over a decade after Patrick Mahomes' season-ending knee injury. A healthy Mahomes returning to a roster that has been to five of the last six Super Bowls is the biggest swing factor for 2026.
