Power-rating comparison
Chiefs–Dolphins is a coin flip on our numbers
The better team here is the visitor, and it still is not favored. The Chiefs rate -0.5 (20th of 32) against -3.0 for the Dolphins (28th) — but 2.5 points of home field is larger than the 2.5-point gap between them, so the model lands at 50% for the Dolphins anyway. That is the whole story of this line: venue, not talent. It rates as the 1st-closest of the 16 games in Week 3, and a game this tight is decided by the price, not the model.
Zoom out to the full season and the model projects the Dolphins at 6.7 wins (favored in 4 of 17) and the Chiefs at 8.2 (favored in 8) — 1.4 wins apart across the year. By win probability this is the 14th-hardest game on the Dolphins' schedule and the 9th-hardest on the Chiefs'.
The sharpest unit gap in the game runs one way: the Chiefs offense grades -0.1 (20th of 32) against a Dolphins defense at -2.5 (28th) — 2.4 points of separation on our scale, and the single biggest reason the line sits where it does. Going the other direction, the Dolphins offense (-1.3, 25th) meets the Chiefs defense (-0.8, 18th), a 0.4-point gap. Special teams adds to it: the Dolphins grade +0.8, 6th in the league, against +0.4 (19th) on the other side — close to a point of hidden margin.
One team has owned this series: the Chiefs are 6-3 in 9 regular-season meetings since 2002. They have also met 4 times in the playoffs. They last met in 2023: Chiefs won 21-14 in November. Over their last 4 meetings the Dolphins 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.
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 Dolphins at 50% 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-26SEP27KCMIA is not listed, and a model number is not a market number. Because the model is close to even here — 50% / 50% — the tradable window is narrow: Dolphins at 45c or below, Chiefs at 45c 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.

Chiefs vs Dolphins — frequently asked
Who is favored in Chiefs vs Dolphins in Week 3?
Our power-rating model favors the Dolphins by 0 points, a 50% win probability over the Chiefs. The Dolphins rate 28th of 32 (-3.0) and the Chiefs 20th (-0.5); Kalshi has not listed KXNFLGAME-26SEP27KCMIA yet, so the model line is the only number on the board.
Why does the model call this a toss-up?
Because the Dolphins (-3.0, 28th) and Chiefs (-0.5, 20th) are only 2.5 rating points apart. The 2.5-point home-field adjustment is larger than the gap between the teams, so home field is effectively the entire margin and the split lands at 50%/50%. In games like this the model is not the deciding input — the contract price is.
How do you take a position on Chiefs vs Dolphins?
The contract will be KXNFLGAME-26SEP27KCMIA 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 Dolphins at 45c or below, or the Chiefs at 45c 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 Dolphins host the Chiefs?
