Power-rating comparison
AFC East math: Patriots at Bills
New England Patriots at Buffalo Bills is a AFC East game, the first of two meetings, with the rematch in Week 13. The model has the Bills by 1.5 (54%) off a +4.2 to +5.4 rating gap. Division games carry weight the model does not price: head-to-head is the first tiebreaker in the AFC East, so a win here is worth more in January than the standings column shows.
The sharpest unit gap in the game runs one way: the Patriots offense grades +3.9 (4th of 32) against a Bills defense at -0.2 (11th) — 4.1 points of separation on our scale, and the single biggest reason the line sits where it does. Going the other direction, the Bills offense (+4.0, 2nd) meets the Patriots defense (+1.3, 6th), a 2.7-point gap.
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 meet again in Week 13, which makes a sweep the outcome with real leverage on the AFC East race.
Season-long, the model can barely split them: 10.3 projected wins for the Bills against 11.0 for the Patriots, favored in 13 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 Bills' schedule and 2nd-hardest on the Patriots'.
One team has owned this series: the Patriots are 36-12 in 48 regular-season meetings since 2002. They have also met 1 time in the playoffs. They last met in 2025: Bills won 35-31 in December. Over their last 4 meetings the Bills are 2-2. 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 50-55% in 870 of them, and those sides won 52%. The Bills at 54% 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-26OCT04NEBUF is not listed, and a model number is not a market number. Because the model is close to even here — 54% / 46% — the tradable window is narrow: Bills at 49c or below, Patriots at 41c 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.

Patriots vs Bills — frequently asked
Who is favored in Patriots vs Bills in Week 4?
Our power-rating model favors the Bills by 1.5 points, a 54% win probability over the Patriots. The Bills rate 4th of 32 (+4.2) and the Patriots 2nd (+5.4); Kalshi has not listed KXNFLGAME-26OCT04NEBUF yet, so the model line is the only number on the board.
How much does a AFC East result matter here?
Head-to-head is the first tiebreaker between two AFC East teams and division record is the next, so this result carries more than one game of standings weight. These two also meet in Week 13. Our model does not adjust for any of that — it prices the Bills by 1.5 on ratings and home field alone.
