Los Angeles is the heavy side in the Week 1 opener at SoFi Stadium, and the 2025 records are why: the Chargers went 11-6 and reached the AFC wild-card round, while Arizona went 3-14 and lost its last nine games. Kalshi and Polymarket price the moneyline within 1c of each other, so the value question on this board is the spread ladder rather than the side. The board carries roughly $291K in lifetime volume across both platforms and resolves Sunday, September 13, 2026. The live board above has the current prices.
Los Angeles is the chalk in this Week 1 opener at SoFi Stadium, and the two 2025 seasons behind the matchup explain the size of the gap. The Chargers finished 11-6, outscored opponents 368 to 340, and lost 16-3 at New England in the AFC wild-card round. Arizona finished 3-14, was outscored 355 to 488, and lost its final nine games by an average of 15.8 points after a 2-0 start. The board carries roughly $291K in lifetime volume across Kalshi and Polymarket and resolves on Sunday, September 13, 2026.
Cardinals vs Chargers Market Context
As of September 5, the moneyline prices Los Angeles at 82.5c blended (83c on Kalshi, 82c on Polymarket) against Arizona at 19c on both books. The two sides sum to 101.5c, so stripping the market's built-in margin leaves the Chargers at roughly 81% and the Cardinals at roughly 19%. Those two legs carry $100.5K and $64.2K of lifetime volume respectively, which is more than half the board.
The cross-platform read is the quiet story here. Kalshi and Polymarket sit 1c apart on the Chargers and dead level on the Cardinals, and the two books are also within 1c on the most-traded alternate spread rung. Both are quoting the same game at the same number, which is what a two-book board looks like when neither side has information the other lacks. There is no better price to shop between them on the moneyline.
The spread board is more interesting than the moneyline. Chargers -7.5 carries the most spread volume at $12.2K and prices at 59c, but the 50% crossover sits lower down the ladder: -9.5 trades at 53c and -10.5 at 46.5c blended (46c Kalshi, 47c Polymarket). The market's true line is therefore near Chargers -10, wider than the rung most of the money is sitting on. On the total, over 46.5 is the single most-traded contract on the entire board at $20.9K and 54c, with over 47.5 at 48.5c, which puts the implied total right around 47 points.
Line movement over the captured window, which runs from 5:15 PM ET on September 4 to 5:08 PM ET on September 5, shows a moneyline that has not moved. The Chargers opened that window at 83c on Kalshi, dipped to 81c twice overnight, and printed 83c on each of the last nine captures. Arizona went 18c to 19c on Polymarket in the first hour and has been pinned at 19c ever since. The volatility is all in the spread: Chargers -7.5 ranged between 50c and 62c across 31 captures in the same 24 hours and settled at 59c. That is a stable game price with an unstable margin-of-victory price underneath it, which is the normal signature of a Week 1 board where nobody has seen the teams play yet.
The Cardinals vs Chargers Quarterback Matchup
Justin Herbert enters his third season under Jim Harbaugh, who has taken the Chargers to the playoffs in each of his first two years. Herbert threw for 3,727 yards with 26 touchdowns and 13 interceptions in 16 games in 2025, completing 66.4% at a 94.1 passer rating, and added a career-high 498 rushing yards on 83 carries at 6.0 per attempt. The number that should worry Chargers backers is 54: that is how many sacks he absorbed in 2025, a career high and up from 41 the year before. Arizona's pass rush against a line that leaked that often is the most direct route to the Cardinals covering.
Arizona is starting over. Jonathan Gannon was fired on January 5, 2026 after a 15-36 run across three seasons, and Mike LaFleur takes over for his first head-coaching job with Nathaniel Hackett installing the offense. Kyler Murray was released on March 11, ending a seven-year run and leaving the job to Jacoby Brissett, who already did it for most of last season. Brissett took over after Murray's season-ending injury and threw for 3,366 yards with 23 touchdowns and 8 interceptions in 14 games, posting the identical 94.1 rating Herbert did. He was also sacked 43 times, so both quarterbacks in this game spent 2025 under heavy pressure.
Brissett missed the start of camp in a contract dispute and returned on July 26 after a reworked deal that locked in $15.5M. ESPN reported on September 1 that he needed time to adjust to LaFleur's terminology and has since gotten comfortable, which is the honest version of a quarterback learning a third system in three years. Around him, Marvin Harrison Jr. and Trey McBride are the established pass catchers, and third overall pick Jeremiyah Love is listed as questionable at running back on the Week 1 depth chart. A rookie back sitting or playing limited snaps behind a new offense is the sort of detail that moves the total more than the moneyline.
Fifteen passing-yardage prop rungs are posted on this board, running from 149.5 to 399.5 for Herbert and 149.5 to 349.5 for Brissett. None of them carry a quote or any volume yet, so the props exist as structure rather than as a price you can read. Watch them for the first real quotes as kickoff approaches.
When the Cardinals vs Chargers Market Resolves
The market resolves on the result of the game, which kicks off at 4:25 PM ET on Sunday, September 13, 2026 at SoFi Stadium in Inglewood, California, on CBS. The moneyline settles to the team that wins outright, with no push condition. The spread and total ladders settle against the final score, and every rung on this board is a half point, so no spread or total contract can push.
Key Cardinals vs Chargers Catalysts
- Herbert's protection: he took 54 sacks in 2025, a career high and 13 more than in 2024, and that is the cleanest path to an Arizona cover.
- Brissett in a new system: his first start under Mike LaFleur, after a holdout that cost him the front half of camp and a July 26 return.
- Jeremiyah Love's status: the third overall pick is listed questionable at running back, which reads through to the total more than the side.
- The spread ladder's real line: the crossover sits near Chargers -10 while the most-traded rung is -7.5, so the ladder and the volume disagree.
- A tight two-book board: Kalshi and Polymarket are within 1c on the moneyline, so there is no cross-platform price to choose between.
- No 2026 form to price: neither team has played a regular-season snap, so this line is built entirely on 2025 results and offseason roster change.
Related Cardinals vs Chargers Markets
Both season-long boards for these teams trade separately: the Chargers 2026 win total prices how far Los Angeles carries an 11-6 season forward, and the Cardinals playoff market prices whether Arizona ends a four-year absence in LaFleur's first year. The Super Bowl LXI champion board is where both of those roll up.

Resolution Criteria
Resolves to the team that wins the game, scheduled for 4:25 PM ET on Sunday, September 13, 2026 at SoFi Stadium in Inglewood, California. The winning team’s moneyline contract pays $1 per share and the losing team’s resolves to $0, with no push condition on a two-way moneyline. Spread contracts settle on the final margin and total contracts on the combined final score; every spread and total rung on this board is set at a half point, so none of them can push. Settlement follows the official final result on the scheduled date. If the game is postponed, the market settles on the completed result; if it is canceled outright, it voids per each platform’s own rules.
Key Factors
- Justin Herbert took a career-high 54 sacks in 2025, up from 41 in 2024, making Chargers pass protection the clearest route to an Arizona cover

- Third overall pick Jeremiyah Love is listed questionable at running back on Arizona’s Week 1 depth chart
- The spread ladder crosses 50% near Chargers -10 while the most-traded rung is -7.5 at $12.2K
- Kalshi and Polymarket are within 1c on the moneyline, so there is no cross-platform price to choose between
- Neither team has played a 2026 regular-season snap, so the line is built on 2025 results and offseason roster change alone
