Quick Answer
As of July 28, 2026, our model favors the Jaguars by 0.5 in Jacksonville Jaguars vs Cincinnati Bengals, NFL Week 4 2026 — 52% to win, and effectively a toss-up — the teams are 3.3 rating points apart.

Power-rating comparison
Jaguars–Bengals is a coin flip on our numbers
There is almost nothing between these two on our numbers. The Bengals rate -0.6 (21st of 32), the Jaguars +2.7 (6th) — 3.3 points apart before home field, inside the error bar of any preseason rating. The split comes out 48%/52%, and this rates as the 2nd-closest game of the 16 in Week 4. When the model has no opinion worth holding, the price has to supply the edge.
Season-long, the model can barely split them: 8.6 projected wins for the Bengals against 9.5 for the Jaguars, favored in 7 and 11 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 Bengals' schedule and 9th-hardest on the Jaguars'.
The sharpest unit gap in the game runs one way: the Jaguars offense grades +1.8 (9th of 32) against a Bengals defense at -2.1 (25th) — 3.9 points of separation on our scale, and the single biggest reason the line sits where it does. Going the other direction, the Bengals offense (+0.7, 15th) meets the Jaguars defense (0.0, 9th), a 0.7-point gap.
One team has owned this series: the Bengals are 8-4 in 12 regular-season meetings since 2002. They last met in 2025: Bengals won 31-27 in September. Over their last 4 meetings the Bengals are 4-0. 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.
Conditions are unlikely to be the story: across 11 Cincinnati home games in October since 2015, the median temperature was 66°F and the median wind 6 mph. That is a neutral-weather profile, which is worth knowing mostly because it removes an excuse from both sides.
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 Jaguars at 52% 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-26OCT04JACCIN is not listed, and a model number is not a market number. Because the model is close to even here — 48% / 52% — the tradable window is narrow: Bengals at 43c or below, Jaguars at 47c 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.

Jaguars vs Bengals — frequently asked
Who is favored in Jaguars vs Bengals in Week 4?
Our power-rating model favors the Jaguars by 0.5 points, a 52% win probability over the Bengals. The Bengals rate 21st of 32 (-0.6) and the Jaguars 6th (+2.7); Kalshi has not listed KXNFLGAME-26OCT04JACCIN yet, so the model line is the only number on the board.
Why does the model call this a toss-up?
Because the Bengals (-0.6, 21st) and Jaguars (+2.7, 6th) are only 3.3 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 48%/52%. In games like this the model is not the deciding input — the contract price is.
How do you take a position on Jaguars vs Bengals?
The contract will be KXNFLGAME-26OCT04JACCIN 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 Bengals at 43c or below, or the Jaguars at 47c 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 Bengals host the Jaguars?
Jacksonville Jaguars visit the Cincinnati Bengals on Sunday, October 4, 2026 — a Sunday game in NFL Week 4, at Paycor Stadium, Cincinnati, OH.

Across all 17 games the model projects the Bengals at 8.6 wins (favored in 7) and the Jaguars at 9.5 (favored in 11). This game ranks 8th-hardest on the Bengals' schedule and 9th-hardest on the Jaguars', by model win probability.
How often does the model win when it is 52% on a team like the Jaguars?
52% 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 50-55% range 870 times, and those teams won 52% of them. The Jaguars at 52% over the Bengals sit in that band, off a 0.5-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.
