What the model sees in Lions at Cardinals
The Lions travel to face the Cardinals in Week 5. Our power ratings put the Cardinals 30th of 32 at -3.7 (Below Avg tier) and the Lions 7th at +2.5 (Playoff tier) — a 6.2-point gap that home field narrows to a 4-point line on the Lions, 62% to win. It rates as the 15th-widest of the 15 games in Week 5.
The sharpest unit gap in the game runs one way: the Lions offense grades +1.3 (10th of 32) against a Cardinals defense at -2.9 (30th) — 4.2 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, 22nd) meets the Lions defense (+0.7, 6th), a 1.4-point gap. One more tilt worth noting: special teams favors the Lions +0.6 (11th of 32) to -0.1 (30th).
Zoom out to the full season and the model projects the Cardinals at 6.5 wins (favored in 3 of 17) and the Lions at 9.8 (favored in 13) — 3.3 wins apart across the year. By win probability this is the 11th-hardest game on the Cardinals' schedule and the 11th-hardest on the Lions'.
The series is dead level: 8-8 across 17 regular-season meetings since 2002. They last met in 2024: Lions won 20-13 in September. Over their last 4 meetings the Cardinals are 0-4. History says these two are hard to separate, which is the one place it agrees with the ratings.
Does the model earn this number? In 666 of the 3266 walk-forward games it has been graded on (2013-2024, no market line used), it landed in the 60-65% range. Those favourites went 59%. The 62% on the Lions here sits in that same band, and the history runs slightly behind the claim.
Kalshi has not listed KXNFLGAME-26OCT11DETARI, so there is no price on the board and no edge to quote. The model's number to hold it to: Cardinals 38%, Lions 62%. Applying our five-point threshold, that makes Cardinals contracts a buy at 33c or below and Lions contracts a buy at 57c 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.
