Power-rating comparison
AFC West math: Chiefs at Raiders
Kansas City Chiefs at Las Vegas Raiders is a AFC West game, the first of two meetings, with the rematch in Week 18. The model has the Chiefs by 3 (58%) off a -5.8 to -0.5 rating gap. Division games carry weight the model does not price: head-to-head is the first tiebreaker in the AFC West, so a win here is worth more in January than the standings column shows.
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.
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 meet again in Week 18, which makes a sweep the outcome with real leverage on the AFC West race.
Zoom out to the full season and the model projects the Raiders at 5.6 wins (favored in 1 of 17) and the Chiefs at 8.2 (favored in 8) — 2.6 wins apart across the year. By win probability this is the 15th-hardest game on the Raiders' schedule and the 14th-hardest on the Chiefs'.
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 Raiders are 1-3. 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 Chiefs at 58% 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-26OCT04KCLV, so there is no price on the board and no edge to quote. The model's number to hold it to: Raiders 42%, Chiefs 58%. Applying our five-point threshold, that makes Raiders contracts a buy at 37c or below and Chiefs contracts a buy at 53c 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.

Chiefs vs Raiders — frequently asked
Who is favored in Chiefs vs Raiders in Week 4?
Our power-rating model favors the Chiefs by 3 points, a 58% win probability over the Raiders. The Raiders rate 32nd of 32 (-5.8) and the Chiefs 20th (-0.5); Kalshi has not listed KXNFLGAME-26OCT04KCLV yet, so the model line is the only number on the board.

Head-to-head is the first tiebreaker between two AFC West teams and division record is the next, so this result carries more than one game of standings weight. These two also meet in Week 18. Our model does not adjust for any of that — it prices the Chiefs by 3 on ratings and home field alone.
