Power-rating comparison
What the model sees in Cardinals at Chiefs
The Cardinals travel to face the Chiefs in Week 11. Our power ratings put the Chiefs 20th of 32 at -0.5 (Average tier) and the Cardinals 30th at -3.6 (Below Avg tier) — a 3.1-point gap that home field widens to a 5.5-point line on the Chiefs, 66% to win. It rates as the 6th-widest of the 13 games in Week 11.
The sharpest unit gap in the game runs one way: the Chiefs offense grades -0.1 (20th of 32) against a Cardinals defense at -2.9 (29th) — 2.8 points of separation on our scale, and the single biggest reason the line sits where it does. Going the other direction, the Cardinals offense (-0.7, 23rd) meets the Chiefs defense (-0.8, 18th), a 0.2-point gap. One more tilt worth noting: special teams favors the Chiefs +0.4 (19th of 32) to -0.1 (30th).
Zoom out to the full season and the model projects the Chiefs at 8.2 wins (favored in 8 of 17) and the Cardinals at 6.4 (favored in 3) — 1.8 wins apart across the year. By win probability this is the 15th-hardest game on the Chiefs' schedule and the 8th-hardest on the Cardinals'.
One team has owned this series: the Chiefs are 5-1 in 6 regular-season meetings since 2002. They last met in 2022: Chiefs won 44-21 in September. Over their last 4 meetings the Chiefs are 3-1. Worth saying plainly — the model does not know any of that. It reads 2026 ratings and nothing else, so a lopsided series is a story, not a number on this page.
Does the model earn this number? In 448 of the 3266 walk-forward games it has been graded on (2013-2024, no market line used), it landed in the 65-70% range. Those favourites went 68%. The 66% on the Chiefs here sits in that same band, and the history backs it.
Kalshi has not listed KXNFLGAME-26NOV22ARIKC, so there is no price on the board and no edge to quote. The model's number to hold it to: Chiefs 66%, Cardinals 34%. Applying our five-point threshold, that makes Chiefs contracts a buy at 61c or below and Cardinals contracts a buy at 29c or below — anything between is inside the noise, and we pass. Week 1's KXNFLGAME contracts opened in May 2026 and the rest of the slate lists as the season gets closer; this page picks up the price automatically when it does.
