What the Odds Say About Seattle vs. Denver
The Seattle Seahawks travel to Denver to face the Broncos on Thursday, October 15, with kickoff set for 5:15 PM PDT. The consensus market has Seattle as a modest road favorite, which is notable given Denver's home-field advantage at altitude. Here is what the current lines are showing and what bettors should know heading into this Week 6 matchup.
Spread: Seattle Seahawks -1.5 to -2.5 Across the Market
The spread market is showing a meaningful split. Most major books have the Seahawks favored by 2.5, including FanDuel, DraftKings, BetRivers, and 1xBet. A notable cluster, including Caesars Sportsbook, BetOnline.ag, GTbets, and BetUS, have the line at Seattle -1.5.
That full-point gap matters in a low-total game. If Seattle wins by exactly a field goal, the difference between -1.5 and -2.5 is the difference between a cover and a loss. Shop for the best number before placing your bet. For live spreads where that gap creates a middling opportunity, the Middle Finder can surface those in real time.
The best price on Denver against the spread is at LowVig.ag, where the Broncos are +1.5 at -105 compared to the standard -110 juice elsewhere.
Moneyline: Seattle a Clear but Not Runaway Favorite
Seattle is the consensus favorite on the moneyline across every major US-facing book. The range runs from around -125 at DraftKings and GTbets on the low end to -143 at William Hill, 888sport, and Smarkets on the high end. Denver ranges from +102 at Smarkets to +122 at Kalshi.
The midpoint of the Seattle range, roughly -135, implies a win probability of around 57 percent. That is not a dominant number, and it reflects how competitive the market views this matchup.
The spread on Denver's moneyline is also worth noting. Denver at +122 (Kalshi) versus +102 (Smarkets) is a 20-cent difference on the same bet. If you are taking the Broncos outright, shopping that gap meaningfully improves your payout. Use the Odds Converter to translate any of these American odds into implied probability.
Total: Market Clustered at 42 to 42.5
The over/under is tightly grouped, with most books posting 42.5 and a handful, including BetOnline.ag, BetUS, GTbets, and LowVig.ag, sitting at 42. The over is priced slightly more favorably at several books, with FanDuel and 1xBet both offering it at -105.
A 42 to 42.5 total on a Thursday night road game for Seattle in Denver's altitude suggests the market does not expect a shootout. Factor in the short week and travel conditions when evaluating both offenses.
Key Factors to Watch Before Kickoff
Injury reports: With the game still nine days out, the injury picture will sharpen considerably. Any news on key skill position players could shift this line by a point or more. Watch the Wednesday practice reports, which will serve as the final injury designations before a Thursday kickoff.
Line movement: The spread sitting between -1.5 and -2.5 at different books suggests the market has not fully settled. If the line moves from -1.5 to -2.5 at the books currently sitting lower, that signals meaningful action on Seattle.
Altitude and home field: Denver's altitude is a real factor in prime-time games, particularly for a visiting team on a short week. The market is already pricing some of this in by keeping Seattle's spread modest, but it is worth weighing when evaluating the total as well.
Implied probability: At roughly 57 percent implied probability for Seattle, this is not a one-sided market. That uncertainty creates room for value on both sides depending on your read of the matchup.
