Power-rating comparison
Bears–Panthers is a coin flip on our numbers
There is almost nothing between these two on our numbers. The Panthers rate -1.9 (24th of 32), the Bears +1.5 (10th) — 3.4 points apart before home field, inside the error bar of any preseason rating. The split comes out 47%/53%, and this rates as the 5th-closest game of the 16 in Week 1. When the model has no opinion worth holding, the price has to supply the edge.
Zoom out to the full season and the model projects the Panthers at 7.5 wins (favored in 4 of 17) and the Bears at 8.9 (favored in 11) — 1.4 wins apart across the year. By win probability this is the 11th-hardest game on the Panthers' schedule and the 7th-hardest on the Bears'.
The sharpest unit gap in the game runs one way: the Bears offense grades +1.9 (8th of 32) against a Panthers defense at -1.7 (22nd) — 3.6 points of separation on our scale, and the single biggest reason the line sits where it does. Going the other direction, the Panthers offense (-0.8, 24th) meets the Bears defense (-0.9, 19th), a 0.1-point gap.
One team has owned this series: the Bears are 8-3 in 11 regular-season meetings since 2002. They have also met 1 time in the playoffs. They last met in 2024: Bears won 36-10 in October. Over their last 4 meetings the Panthers are 0-4. 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.
Conditions are unlikely to be the story: across 9 Carolina home games in September since 2015, the median temperature was 83°F and the median wind 4 mph. That is a neutral-weather profile, which is worth knowing mostly because it removes an excuse from both sides.
Calibration check, because a near-even number is the easiest kind to overtrust: across 3266 walk-forward games (2013-2024) the model gave a side 50-55% in 870 of them, and those sides won 52%. The Bears at 53% are in that band. A margin that thin is why we would rather wait for a price than call it a lean.
Kalshi's KXNFLGAME-26SEP13CHICAR contract implies 43% for the Panthers against our 47% — a 4.9-point gap. That is inside our 5-point threshold, so we pass — the market and the model are telling the same story.
