How to Bet on Chiefs vs. Seahawks

1. Backing the Home Favorite (Seahawks −2.5 / 7/10): The Seattle Seahawks enter Lumen Field as narrow 2.5-point home favorites. Backing Seattle outright on the moneyline at 7/10 (−143) requires laying juice, yielding a $70 net return on a $100 wager upon victory. Bettors seeking stronger return value without taking on excessive risk can lay the points on the spread at −2.5 (17/20 odds), which requires Seattle to win by at least a field goal while bypassing the steeper moneyline cost.
2. Chasing the Road Dog (Chiefs +2.5 / 63/50): Kansas City travels to Seattle in the unfamiliar spot of a plus-money road underdog. Taking the Chiefs straight-up on the moneyline at 63/50 (+126) yields a $126 net profit on a $100 wager if they pull off the outright win. For added security against late-game field-goal variance, taking the Chiefs at +2.5 on the spread at even money (1/1 / +100) provides insurance, cashing if Kansas City wins outright or loses by two points or fewer.
3. Targeting the Game Total (Over/Under 42.5 Points): The total is pegged at a modest 42.5 points, with Over 42.5 priced at 100/107 and Under 42.5 priced at 100/109. Over backers will lean into Patrick Mahomes and Kansas City's league-leading rush efficiency (5.51 yards per carry) trading blows with Seattle's high-tempo offense. Conversely, Under bettors have strong backing from Lumen Field's notorious crowd noise and Kansas City's stingy defense, which has surrendered just seven touchdowns across their opening five contests.
