Cardinals vs Chargers Prediction & Odds (Sep 13)

A Big Favorite With a Small Crack In It

Los Angeles is priced at -480 on the moneyline, which means the market gives the Chargers roughly an 80 percent shot to win this football game. That is heavy. But the Arizona price on the other side, +410 at Fliff, quietly pays more than that same market read says it should. Two numbers, one game, and only one of them is on your side. Week 1 openers are where stale prices hide, and Cardinals vs Chargers is a clean example.

The Matchup

This is Week 1 of the 2026 regular season, Sunday, September 13, 2026, kicking off at 4:25 PM ET at SoFi Stadium. As of publication both clubs sit at 0-0, which is simply where every team starts before a snap is played. There is no season series yet and no form to lean on, so the entire market opinion is built from projections, roster value and home field.

That opinion is loud: Los Angeles is laying 9.5 points, meaning oddsmakers expect the Chargers to win by about a touchdown and a half. For the reverse-order crowd searching Chargers vs Cardinals, it is the same game, the same number, and the same question. Is Arizona really a nine-and-a-half point dog in September?

Players to Watch

The names our data flags all sit on the injury report, and in a Week 1 game with no tape, availability is the story. For the Los Angeles Chargers, edge defender Tuli Tuipulotu is listed Questionable, with cornerback Deane Leonard and offensive lineman Isaiah World both ruled Out. For the Arizona Cardinals, Jeremiyah Love is Questionable, while offensive lineman Isaiah Adams and defensive back Garrett Williams are both Out. Six names in total, four of them already ruled out. Watch the secondary matchups in particular: both teams are missing a defensive back, and thin coverage groups tend to push scoring up, not down.

The Numbers

Moneyline means a straight bet on who wins, no margin required. Chargers -480 (best at BetRivers) profits $20.83 on a $100 bet and loses the full $100 if they fall. Cardinals +410 (best at Fliff) profits $410.00 on a $100 bet. The point spread is a margin bet. Arizona +9.5 at -105 (best at DraftKings) wins if Arizona wins outright or loses by 9 or fewer, and it loses on a 10-point defeat.

There is no push at a half point, so no ties, no refunds. Los Angeles -9.5 at +104 (best at ProphetX) wins only if the Chargers win by 10 or more; a 9-point win loses. The total is the combined score of both teams. Over 47.5 is +100 at theScore Bet, Under 47.5 is -112 at BetMGM. Those best prices come from shopping multiple books, and that habit is worth more than most handicaps.

Where the Value Is

Strip the sportsbook's built-in margin out and the market reads this at 80 percent Chargers, 20 percent Cardinals. Small edge, real edge.

Injuries

Arizona is down Isaiah Adams up front and Garrett Williams in the back end, with Jeremiyah Love uncertain. Questionable means exactly that, uncertain, and we do not assign it odds. Los Angeles loses Deane Leonard and Isaiah World outright, with Tuli Tuipulotu uncertain. If Tuipulotu sits, the Chargers' pass rush thins out against an Arizona line already patched together. Check Sunday's inactives before kickoff.

The Pick

Arizona Cardinals moneyline +410 at Fliff, small stake. We are not predicting an upset. We are buying a price that pays more than the market's own number, at a 19.6 percent break-even against a 20 percent read.

The Prediction

Chargers 24, Cardinals 20. That adds to 44 points, which lands under the 47.5 total, and it is a 4-point margin, so Arizona +9.5 would cash while the underdog moneyline would not. That is the honest base case, and it is precisely why the +410 ticket makes sense at a fraction of a normal stake rather than a full one. That is the read on this number; the Desk posts a documented free play on days like this, and it sits right below.
