New York Jets vs Buffalo Bills

The model does not think this one is close. The Bills rate 4th of 32 at +4.2, the Jets 31st at -4.0, and once home field is applied the line lands on the Bills by 10.5 — 78% to win. That is the 2nd-widest gap among the 16 games on the Week 18 board. A preseason rating spread this size is not a promise: it says nothing about turnovers, health, or a defense that shows up different than last year. What it does say is that the Jets need the price to be wrong, not the matchup.

The sharpest unit gap in the game runs one way: the Bills offense grades +4.0 (2nd of 32) against a Jets defense at -2.2 (27th) — 6.2 points of separation on our scale, and the single biggest reason the line sits where it does. Going the other direction, the Jets offense (-3.1, 30th) meets the Bills defense (-0.2, 11th), a 2.8-point gap. Special teams adds to it: the Jets grade +1.3, 1st in the league, against +0.4 (17th) on the other side — close to a point of hidden margin.

Zoom out to the full season and the model projects the Bills at 10.3 wins (favored in 13 of 17) and the Jets at 6.5 (favored in 4) — 3.8 wins apart across the year. By win probability this is the 17th-hardest game on the Bills' schedule and the 2nd-hardest on the Jets'. It is the softest spot on the Bills' entire schedule.

On the standings side, AFC East 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 already played in Week 10, so a season sweep is on the table here on the AFC East race.

Recent history, for context only: 48 regular-season meetings since 2002, 26-22 in the Bills' favour, plus 1 playoff game. They last met in 2025: Bills won 35-8 in January. Over their last 4 meetings the Bills are 4-0. It is not an input to the line — rosters turn over faster than series records do.

A note on confidence this high: the model has only been this sure 139 times in 3266 walk-forward games from 2013-2024. Teams it put in the 75-80% range won 74% of those. So a 78% Bills number is well supported by the record, and still loses about 26 times in 100 — which is exactly why the position is a price question, not a certainty question.

There is no market to compare against yet — Kalshi has not listed KXNFLGAME-27JAN10NYJBUF — and we are not going to invent a price. What the model will say when it opens: Bills YES is only worth buying at 73c or below, which is a demanding ask on a side the model already has at 78%. The likelier position on a game this lopsided is the Jets at 17c or below, where the payoff does the work. 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.
