Detroit Lions vs Green Bay Packers

This is the second meeting. The Lions and Packers already played in Week 7, and now the Lions make the return trip in Week 18. Familiarity does not show up in a power rating, so the model prices it the same way it prices everything else: +2.9 against +2.4, plus home field, equals the Packers by 3 (59%). 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 Packers offense grades +3.2 (5th of 32) against a Lions defense at +0.6 (7th) — 2.6 points of separation on our scale, and the single biggest reason the line sits where it does. Going the other direction, the Lions offense (+1.2, 10th) meets the Packers defense (-0.5, 15th), a 1.7-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 7, so a season sweep is on the table here on the NFC North race.

Season-long, the model can barely split them: 9.7 projected wins for the Packers against 9.8 for the Lions, favored in 13 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 8th-hardest on the Packers' schedule and 2nd-hardest on the Lions'.

One team has owned this series: the Packers are 32-16 in 48 regular-season meetings since 2002. They have also met 2 times in the playoffs. They last met in 2025: Packers won 31-24 in November. Over their last 4 meetings the Packers are 2-2. 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.

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 55-60% in 797 of them, and those sides won 57%. The Packers at 59% are in that band. A margin that thin is why we would rather wait for a price than call it a lean.

Kalshi has not listed KXNFLGAME-27JAN10DETGB, so there is no price on the board and no edge to quote. The model's number to hold it to: Packers 59%, Lions 41%. Applying our five-point threshold, that makes Packers contracts a buy at 54c or below and Lions contracts a buy at 36c 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.
