Arizona Cardinals vs Los Angeles Rams

The model does not think this one is close. The Rams rate 1st of 32 at +6.3, the Cardinals 30th at -3.6, and once home field is applied the line lands on the Rams by 12.5 — 82% to win. That is the 1st-widest gap among the 14 games on the Week 6 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 Cardinals need the price to be wrong, not the matchup.

The sharpest unit gap in the game runs one way: the Rams offense grades +4.2 (1st of 32) against a Cardinals defense at -2.9 (29th) — 7.0 points of separation on our scale, and the single biggest reason the line sits where it does. Going the other direction, the Cardinals offense (-0.7, 23rd) meets the Rams defense (+1.9, 2nd), a 2.6-point gap.

Zoom out to the full season and the model projects the Rams at 11.3 wins (favored in 16 of 17) and the Cardinals at 6.4 (favored in 3) — 4.8 wins apart across the year. By win probability this is the 17th-hardest game on the Rams' schedule and the 1st-hardest on the Cardinals'. Nothing on the Cardinals' schedule projects harder than this one.

On the standings side, NFC West 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 10, which makes a sweep the outcome with real leverage on the NFC West race.

Recent history, for context only: 48 regular-season meetings since 2002, 28-20 in the Rams' favour, plus 2 playoff games. They last met in 2025: Rams won 37-20 in January. Over their last 4 meetings the Rams are 3-1. It is not an input to the line — rosters turn over faster than series records do.

There is no market to compare against yet — Kalshi has not listed KXNFLGAME-26OCT18ARILAR — and we are not going to invent a price. What the model will say when it opens: Rams YES is only worth buying at 77c or below, which is a demanding ask on a side the model already has at 82%. The likelier position on a game this lopsided is the Cardinals at 13c 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.
