Chiefs vs. Seahawks prediction market promos land for Week 7's biggest game in primetime. Five offers are available to new users before the undefeated Kansas City Chiefs visit the defending-champion Seattle Seahawks tonight, Sunday, Oct. 25, 2026, at 8:20 p.m. ET on NBC. Patrick Mahomes faces Sam Darnold in a game many are treating as a Super Bowl preview.
Prediction market apps work differently from traditional sportsbooks. Instead of placing a wager at set odds, you buy a contract on an outcome, and each contract pays $1 if that outcome hits. Contracts trade between 1¢ and 99¢, and the price doubles as the crowd’s implied probability. A 59¢ contract means traders see that result as roughly 59% likely.
Seattle trades at about 59¢ to win on Kalshi and Polymarket US even though Kansas City owns the better record. My preferred Chiefs vs. Seahawks prediction is Seattle on the moneyline, and the full breakdown follows below.

Chiefs vs. Seahawks Prediction: Seahawks Win
I’m taking the Seahawks to win at about 59¢ on Polymarket US, where $100 returns roughly $170 before fees. Four things push me toward Seattle:
- Home field: The game is at Lumen Field, and Seattle is favored by 2.5, even with Kansas City at 5-0 against a 3-3 Seahawks team.
- Champion pedigree: Seattle is the reigning Super Bowl winner, and Darnold gets Mahomes’ defense at home on a national stage.
- Kansas City’s receiver room is thin: Tyquan Thornton went on injured reserve after dislocating his ankle in Week 4, leaving Mahomes with fewer targets to lean on.
- A possible running game boost: Coach Mike Macdonald said Zach Charbonnet would get a full week of practice reps and could make his season debut.
The Chiefs have real arguments, starting with their perfect record and Mahomes. Seattle has also lost three of its last four, so this is not a comfortable favorite. The total sits at 42.5, and the Chiefs trade at about 41¢ to 42¢ if you want the upset.
| Market | Kansas City Chiefs | Seattle Seahawks |
|---|---|---|
| Spread | +3 (50%) | -3 (50%) |
| To Win | 42% | 59% |
| Total Points | Over 42.5 (50%) | Under 42.5 (50%) |
Kickoff for Chiefs vs. Seahawks is at 8:20 p.m. ET on Sunday, October 25, 2026. Odds subject to change. Always check your preferred prediction market for the most up-to-date NFL odds before the game begins.
