Power-rating comparison
Why the model has the Chiefs by 8
The model does not think this one is close. The Chiefs rate 20th of 32 at -0.5, the Raiders 32nd at -5.8, and once home field is applied the line lands on the Chiefs by 8 — 72% to win. That is the 3rd-widest gap among the 16 games on the Week 18 board. A preseason rating spread this size is not a promise: it says nothing about turnovers, health, or a defense that shows up different than last year. What it does say is that the Raiders need the price to be wrong, not the matchup.
The defense wins the headline matchup here: the Chiefs grade -0.8 on that side of the ball (18th of 32) against a Raiders offense at -4.1 (32nd) — 3.3 points the wrong way for the offense. Going the other direction, the Chiefs offense (-0.1, 20th) meets the Raiders defense (-1.9, 24th), a 1.8-point gap.
Zoom out to the full season and the model projects the Chiefs at 8.2 wins (favored in 8 of 17) and the Raiders at 5.6 (favored in 1) — 2.6 wins apart across the year. By win probability this is the 17th-hardest game on the Chiefs' schedule and the 7th-hardest on the Raiders'. It is the softest spot on the Chiefs' entire schedule.
On the standings side, AFC West 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 4, so a season sweep is on the table here on the AFC West race.
One team has owned this series: the Chiefs are 34-14 in 48 regular-season meetings since 2002. They have also met 3 times in the playoffs. They last met in 2025: Raiders won 14-12 in January. 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.
A note on confidence this high: the model has only been this sure 312 times in 3266 walk-forward games from 2013-2024. Teams it put in the 70-75% range won 71% of those. So a 72% Chiefs number is well supported by the record, and still loses about 29 times in 100 — which is exactly why the position is a price question, not a certainty question.
There is no market to compare against yet — Kalshi has not listed KXNFLGAME-27JAN10LVKC — and we are not going to invent a price. What the model will say when it opens: Chiefs YES is only worth buying at 67c or below, which is a demanding ask on a side the model already has at 72%. The likelier position on a game this lopsided is the Raiders at 23c or below, where the payoff does the work. 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.

Raiders vs Chiefs — frequently asked
Who is favored in Raiders vs Chiefs in Week 18?
Our power-rating model favors the Chiefs by 8 points, a 72% win probability over the Raiders. The Chiefs rate 20th of 32 (-0.5) and the Raiders 32nd (-5.8); Kalshi has not listed KXNFLGAME-27JAN10LVKC yet, so the model line is the only number on the board.
What would it take for the Raiders to win?
The 8-point line comes from a 5.3-point rating gap, and a single-game margin has roughly a 13.5-point standard deviation around it — which is why the Raiders still project at 28% rather than zero. Their best structural path is the unit matchup they win on paper. Ratings do not price injuries or turnover luck, which is where most upsets actually come from.
How do you take a position on Raiders vs Chiefs?
The contract will be KXNFLGAME-27JAN10LVKC 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 Chiefs at 67c or below, or the Raiders at 23c 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 Chiefs host the Raiders?
Las Vegas Raiders visit the Kansas City Chiefs on Sunday, January 10, 2027 — a Sunday game in NFL Week 18, at GEHA Field at Arrowhead Stadium, Kansas City, MO.
What does the model project for the Chiefs and Raiders this season?
Across all 17 games the model projects the Chiefs at 8.2 wins (favored in 8) and the Raiders at 5.6 (favored in 1). This game ranks 17th-hardest on the Chiefs' schedule and 7th-hardest on the Raiders', by model win probability.
How often does the model win when it is 72% on a team like the Chiefs?
71% 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 70-75% range 312 times, and those teams won 71% of them. The Chiefs at 72% over the Raiders sit in that band, off a 8-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.
