Quick Answer

As of July 30, 2026, our model favors the Bears by 1.5 in Detroit Lions vs Chicago Bears, NFL Week 17 2026 — 55% to win, and the second NFC North meeting of the year. Kalshi has not listed KXNFLGAME-27JAN03DETCHI yet, so there is no price to compare: when it opens, Bears at 50c or below (or Lions at 40c or below) is where the model would take a position.

The rematch: what the model sees the second time around

This is the second meeting. The Lions and Bears already played in Week 12, and now the Lions make the return trip in Week 17. Familiarity does not show up in a power rating, so the model prices it the same way it prices everything else: +1.5 against +2.4, plus home field, equals the Bears by 1.5 (55%). Where a rematch does matter is the standings — a division sweep is worth more than the two wins suggest.

The sharpest unit gap in the game runs one way: the Lions offense grades +1.2 (10th of 32) against a Bears defense at -0.9 (19th) — 2.1 points of separation on our scale, and the single biggest reason the line sits where it does. Going the other direction, the Bears offense (+1.9, 8th) meets the Lions defense (+0.6, 7th), a 1.3-point gap.

On the standings side, NFC North games are the ones that decide the tiebreakers. Head-to-head record is the first tiebreaker between two teams in the same division, and division record is the next — so the value of this result is not just the win column. They already played in Week 12, so a season sweep is on the table here on the NFC North race.

Season-long, the model can barely split them: 8.9 projected wins for the Bears against 9.8 for the Lions, favored in 11 and 13 of their 17 respectively. Two teams heading for the same neighborhood in the standings tend to produce exactly this kind of line. This game sits 11th-hardest on the Bears' schedule and 4th-hardest on the Lions'.

The series is dead level: 24-24 across 48 regular-season meetings since 2002. They last met in 2025: Lions won 19-16 in January. Over their last 4 meetings the Bears are 0-4. History says these two are hard to separate, which is the one place it agrees with the ratings.

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 55% are in that band. A margin that thin is why we would rather wait for a price than call it a lean.

No price exists for this game yet; KXNFLGAME-27JAN03DETCHI is not listed, and a model number is not a market number. Because the model is close to even here — 55% / 45% — the tradable window is narrow: Bears at 50c or below, Lions at 40c or below, and a pass on everything between. On near-coin-flips the opening price usually lands inside that window, which is why most games like this end up as no-position. 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.

Lions vs Bears — frequently asked

Who is favored in Lions vs Bears in Week 17?

Our power-rating model favors the Bears by 1.5 points, a 55% win probability over the Lions. The Bears rate 10th of 32 (+1.5) and the Lions 8th (+2.4); Kalshi has not listed KXNFLGAME-27JAN03DETCHI yet, so the model line is the only number on the board.

How much does a NFC North result matter here?

Head-to-head is the first tiebreaker between two NFC North teams and division record is the next, so this result carries more than one game of standings weight. These two also meet in Week 12. Our model does not adjust for any of that — it prices the Bears by 1.5 on ratings and home field alone.

How do you take a position on Lions vs Bears?

The contract will be KXNFLGAME-27JAN03DETCHI on Kalshi, a CFTC-regulated exchange open to traders in all 50 states. It has not opened yet; when it does, the model would take the Bears at 50c or below, or the Lions at 40c or below. There is no point spread — you buy a yes or no contract on a team and it settles at $1 or $0.

When and where do the Bears host the Lions?

Detroit Lions visit the Chicago Bears on Sunday, January 3, 2027 — a Sunday game in NFL Week 17, at Soldier Field, Chicago, IL.

What does the model project for the Bears and Lions this season?

Across all 17 games the model projects the Bears at 8.9 wins (favored in 11) and the Lions at 9.8 (favored in 13). This game ranks 11th-hardest on the Bears' schedule and 4th-hardest on the Lions', by model win probability.

How often does the model win when it is 55% on a team like the Bears?

52% of the time. Over 3266 walk-forward games from 2013-2024 — trained only on prior seasons, no market line as an input — the model put a team in the 50-55% range 870 times, and those teams won 52% of them. The Bears at 55% over the Lions sit in that band, off a 1.5-point model line. Straight-up across all 3266 graded games the model picked winners at 59.6%, with a Brier score of 0.236 against 0.25 for a coin flip.
