New England Patriots vs Seattle Seahawks

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 Seahawks rate +5.2 (3rd), the Patriots +5.4 (2nd), and the model opens on the Seahawks 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.

Season-long, the model can barely split them: 10.8 projected wins for the Seahawks against 11.0 for the Patriots, favored in 16 and 15 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 6th-hardest on the Seahawks' schedule and 1st-hardest on the Patriots'. Nothing on the Patriots' schedule projects harder than this one.

The sharpest unit gap in the game runs one way: the Patriots offense grades +3.9 (4th of 32) against a Seahawks defense at +1.8 (4th) — 2.1 points of separation on our scale, and the single biggest reason the line sits where it does. Going the other direction, the Seahawks offense (+2.3, 7th) meets the Patriots defense (+1.3, 6th), a 0.9-point gap. Special teams adds to it: the Seahawks grade +1.2, 2nd in the league, against +0.2 (27th) on the other side — close to a point of hidden margin.

Scheduling note: this is a Wednesday game — the only one on the schedule that day — so it sits outside the main Sunday slate.

One team has owned this series: the Seahawks are 4-2 in 6 regular-season meetings since 2002. They have also met 2 times in the playoffs. They last met in 2024: Seahawks won 23-20 in September. Over their last 4 meetings the Seahawks 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.

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 Seahawks 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-26SEP09NESEA contract implies 66% for the Seahawks against our 57% — a 8.6-point gap. That clears our 5-point threshold, which flags the Patriots as the value side at 36c.
