Edge is model probability minus the market's implied probability, in percentage points. One published number per market: where our sources disagreed we publish the most conservative defensible figure, and where they disagreed by more than 15 points the row is a conflict and carries no stake. ¼ Kelly is the share of a bankroll quarter-Kelly would put on the row at the published price — click it to size against your own bankroll on our Kelly calculator, or call kelly_size from our MCP server inside your own agent.

Broncos vs Chiefs: where the prop prices are
The market’s prices, not ours: each Kalshi strike beside the sportsbook consensus read at the same line, and where the cheaper price for each side actually is. A gap is a price difference, not a call — the Oracle calls above are the opinion.

Broncos–Chiefs is a coin flip on our numbers
The better team here is the visitor, and it still is not favored. The Broncos rate +1.2 (12th of 32) against -0.6 for the Chiefs (20th) — but 2.5 points of home field is larger than the 1.8-point gap between them, so the model lands at 53% for the Chiefs anyway. That is the whole story of this line: venue, not talent. It rates as the 5th-closest of the 16 games in Week 1, and a game this tight is decided by the price, not the model.
Season-long, the model can barely split them: 8.2 projected wins for the Chiefs against 9.1 for the Broncos, favored in 9 and 9 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 10th-hardest on the Chiefs' schedule and 7th-hardest on the Broncos'.
The sharpest unit gap in the game runs one way: the Broncos offense grades +0.6 (16th of 32) against a Chiefs defense at -0.8 (18th) — 1.4 points of separation on our scale, and the single biggest reason the line sits where it does. Going the other direction, the Chiefs offense (-0.2, 20th) meets the Broncos defense (+0.4, 8th), a 0.6-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 8, which makes a sweep the outcome with real leverage on the AFC West race.
Scheduling note: this is a Monday game — the only one on the schedule that day — so it sits outside the main Sunday slate.
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 Chiefs at 53% are in that band. A margin that thin is why we would rather wait for a price than call it a lean.
Kalshi's KXNFLGAME-26SEP14DENKC contract implies 56% for the Chiefs against our 53% — a 3.5-point gap. That is inside our 5-point threshold, so we pass — the market and the model are telling the same story.
