Written before the game and kept as published. Final: Tampa Bay Buccaneers 27, Cincinnati Bengals 33 — the graded call is above.
Week 1 is the widest-error week of the season for every model, ours included — nothing about 2026 is on tape yet, and the ratings are priors, not measurements. With that stated plainly: the Bengals rate +1.9 (8th), the Buccaneers +0.8 (12th), and the model opens on the Bengals by 2.5, 57% to win. Every number on this page will move more between now and kickoff than it will in any week that follows.
Zoom out to the full season and the model projects the Bengals at 10.6 wins (favored in 14 of 17) and the Buccaneers at 7.3 (favored in 10) — 3.3 wins apart across the year. By win probability this is the 11th-hardest game on the Bengals' schedule and the 2nd-hardest on the Buccaneers'.
The sharpest unit gap in the game runs one way: the Bengals offense grades +2.2 (7th of 32) against a Buccaneers defense at +1.2 (3rd) — 1.1 points of separation on our scale, and the single biggest reason the line sits where it does. Going the other direction, the Buccaneers offense (-0.9, 25th) meets the Bengals defense (-1.0, 15th), a 0.1-point gap.
The series is dead level: 3-3 across 6 regular-season meetings since 2002. They last met in 2022: Bengals won 34-23 in December. Over their last 4 meetings the Bengals are 3-1. History says these two are hard to separate, which is the one place it agrees with the ratings.
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 Bengals at 57% 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-26SEP13TBCIN contract implies 50% for the Bengals against our 57% — a 7.5-point gap. No position on this game.
