Arizona is the 54c moneyline favorite over Dallas at 47c, priced identically on Kalshi and Polymarket, and the board has not moved a cent through 29 straight price snapshots. This is a preseason game, so the question the market is actually pricing is playing time rather than roster quality: Jacoby Brissett threw five passes in Arizona's last outing and Dak Prescott has not thrown one all August. Arizona is 1-1 this preseason, Dallas is 1-0, and the board carries about $39K in lifetime cross-platform volume ahead of a 10:00 PM ET kickoff in Glendale.
Arizona sits at 54c and Dallas at 47c on a Cowboys vs Cardinals preseason board that has been completely still, and the reason it prices this close to a coin flip has nothing to do with which roster is better. This is Arizona's third preseason game of four and Dallas's second of three, and in each team's most recent outing the quarterbacks who took the meaningful snaps were the ones competing for jobs, not the ones who will start in September. The board holds roughly $39K in lifetime volume across Kalshi and Polymarket, with the heaviest single leg being $19.1K on the Dallas moneyline.
Kickoff is 10:00 PM ET, which is 7:00 PM local, at State Farm Stadium in Glendale, with national coverage on NFL Network. Two independent sources agree on that slot: ESPN's scoreboard for the date and the Cardinals' own finalized preseason schedule, which lists 7:00 PM Arizona time. This is the Cardinals' only home preseason game of 2026, because their Hall of Fame Game against Carolina was played at Tom Benson Hall of Fame Stadium in Canton, Ohio, and their finale is in Green Bay.
Arizona is 1-1 this preseason after losing 33-30 to Carolina in Canton and beating Las Vegas 27-14. Dallas is 1-0 after a 17-7 win at Seattle. Those three results describe backup football almost from end to end, which is the correct way to read them. Mike LaFleur is in his first preseason as Arizona's head coach with Jacoby Brissett atop the depth chart, and Brian Schottenheimer runs a Dallas team whose starting quarterback has not appeared. Preseason results do not carry over to the regular season in any form, and nothing that happens Saturday night changes a win total, a division price, or a playoff number.
The cross-platform read here is unusually clean. Kalshi and Polymarket both price Arizona at 54c and Dallas at 47c, so there is no gap to discuss on the moneyline at all. The total is the only line where the two books differ, and by a single cent: over 37.5 is 52c on Kalshi and 53c on Polymarket, an average of 52.5c. The Arizona moneyline registered 54c on every one of the 29 snapshots taken in the 24 hours to August 19, so this line has been held rather than pushed.
The box scores from the last two weeks are the whole argument. Against Las Vegas, Brissett went 5-for-5 for 44 yards and a touchdown and then sat down; LaFleur had said before that game that his starters would "play one drive, for sure, and possibly two at most." Gardner Minshew II handled more than three times that workload in the same game, going 14-for-16 for 101 yards and two touchdowns, and Kedon Slovis added nine attempts behind him. In the Hall of Fame Game, when Arizona's starters did not dress at all, rookie Carson Beck threw 19 passes and Slovis threw 10.
Dallas is starker still. Schottenheimer said plainly that "we're not going to play a lot of our starters during the preseason," and at Seattle he meant it: Prescott, CeeDee Lamb and George Pickens all sat, and Joe Milton III (12-for-15, 107 yards, one touchdown) and Sam Howell (8-for-12, 94 yards, one touchdown) split the entire night between them. The Cowboys' leading rushers were Malik Davis with 7 carries for 39 yards and Israel Abanikanda with 7 carries for 36 yards. Javonte Williams did not register a carry.
Neither staff has announced a rotation for this specific game, and that is the honest state of the information as of writing. What is known is that neither team is out of exhibitions after this one: Arizona still visits Green Bay on August 28 and Dallas still hosts New Orleans the same night, so neither staff is under pressure to use this game as a last look. Carson Beck (ribs) is listed questionable for Arizona, as are receiver Xavier Weaver and tight end Elijah Higgins, both with concussions. Dallas lists tackle Tyler Guyton (elbow), running backs Jaydon Blue (shoulder) and Phil Mafah (chest), and defensive tackle Jonathan Bullard (hamstring) as questionable. Those absences matter more here than they would in September, because in an exhibition the depth behind them plays a majority of the snaps.
The spread and total ladders read off the same fact. Arizona -1.5 is 50c and Dallas -1.5 is 46c, so the market gives essentially no side a real edge inside two points. The total of 37.5 is where the preseason effect is most legible: the three games these teams have played produced 63 combined points (both benches, Canton), 41 combined points (starters took a cameo), and 24 combined points (Dallas's all-backup opener). A 37.5 total splits that range almost exactly, which is a reasonable place for it to sit given how little is known about the rotation. DraftKings has drifted toward Arizona, moving from -125 at open to -135 on the moneyline while the prediction-market price stayed pinned at 54c. Cross-platform prices differ for ordinary reasons like fee structure and book depth, and a one-cent spread on a thin preseason total is not a trade.
The moneyline resolves to the team that wins the game on the field on Saturday, August 22, 2026. The spread contracts settle on the final margin and the total contracts settle on combined points scored by both teams, all read off the official final score. The single edge case worth knowing is that the NFL has not played overtime in the preseason since 2021, so a tie after four quarters simply stands, and two teams already carry a tie in their 2026 preseason records. Tie handling on the moneyline is set by each platform's own contract rules, so check the rulebook on Kalshi or Polymarket before taking a side at a price near even. Settlement follows once both platforms mark the game final, usually within hours of the final whistle.
Announced rotation: Whether Brissett takes more than the one or two series LaFleur allotted him against Las Vegas is the single biggest input into both the moneyline and the total.
Dallas quarterback split: Milton and Howell divided the Seattle game evenly at 15 and 12 attempts, and how the staff divides this one signals where that competition stands.
Injury availability: Beck (ribs), Weaver and Higgins (concussions) for Arizona; Guyton (elbow), Blue (shoulder), Mafah (chest) and Bullard (hamstring) for Dallas.
Fourth-quarter roster: The last 15 minutes are played by bubble players fighting for the 53-man cut, which is what makes preseason totals volatile in both directions.
Total 37.5 pricing: The over is 52c on Kalshi and 53c on Polymarket against a three-game sample of 63, 41 and 24 combined points.
Home-field context: This is Arizona's only 2026 preseason home date, and Dallas has now played both of its games away from Texas.
This game settles on its own and moves nothing else, but the season-long boards are the useful context around it. The Arizona Cardinals season win total and the Dallas Cowboys season win total both price the 17-game regular season and neither is affected by an August result. The same is true of Arizona's playoff market, Dallas's playoff market, and the NFC East division board, where Dallas is one of four priced teams.
For games that actually count, both teams open in Week 1 on September 13: Cardinals vs Chargers and Cowboys vs Giants. Full cross-platform boards for both clubs live on the Arizona Cardinals hub and the Dallas Cowboys hub, and every league market sits under NFL prediction markets.
The moneyline resolves to the team that wins the game played at State Farm Stadium in Glendale, Arizona on Saturday, August 22, 2026, with a scheduled kickoff of 10:00 PM ET. Spread contracts settle on the final margin of victory and total contracts settle on the combined points scored by both teams, each read off the official NFL final score. The NFL has not used overtime in preseason games since 2021, so a game tied after four quarters ends in a tie and does not go to an extra period; tie handling on the moneyline is governed by each platform's own contract rules, which differ between Kalshi and Polymarket, so read the rulebook before trading a side near even money. If the game is postponed or canceled, each platform applies its own void or reschedule rule. Contracts pay $1 per share on the winning outcome and $0 on the losing outcome, and settlement normally posts within hours of the game being marked final.
As of August 19, 2026, Arizona is the 54c moneyline favorite and Dallas is 47c, priced identically on Kalshi and Polymarket. The total of 37.5 points is 52c on Kalshi and 53c on Polymarket for the over, and Arizona -1.5 is 50c.
Kickoff is 10:00 PM ET on Saturday, August 22, 2026, which is 7:00 PM local Arizona time, at State Farm Stadium in Glendale. NFL Network carries it nationally. This is the Cardinals' only home preseason game of 2026.
Neither team has announced a rotation for this game. Brian Schottenheimer has said Dallas will not play many starters this preseason and Dak Prescott has not taken a snap, while Mike LaFleur limited Jacoby Brissett to five pass attempts against Las Vegas.
The game trades on both Kalshi and Polymarket, with about $39K in lifetime volume across the two books. The heaviest leg is the Dallas moneyline at $19.1K, followed by the 37.5 total at $10.8K.
Yes. The NFL removed overtime from preseason games in 2021, so a game tied after four quarters stays tied, and two teams already carry a tie in their 2026 preseason records. Each platform sets its own rule for how a tie settles the moneyline.
Watch for each staff's announced availability on Friday and Saturday, because a single extra Brissett series is worth more to this line than any roster comparison. Preseason results do not carry into the regular season, so treat the season win totals for Arizona and Dallas as separate markets.
