| Market | Bears | Seahawks |
| Moneyline | 39¢ | 62¢ |
| Spread (3.5) | Bears +3.5: 54¢ | Seahawks -3.5: 47¢ |
| Total (46.5) | Under 46.5: 51¢ | Over 46.5: 50¢ |
Prices as of Monday morning, rounded to the nearest cent. Prices move until kickoff. Check the full set of NFL odds for every Week 8 game.
Every contract pays $1 if it hits and $0 if it misses. The price tells you the market’s view: Seattle at 62¢ means roughly a 62% chance. Buy a Seahawks contract at 62¢ and you collect $1 on a Seattle win, a 38¢ profit per contract. If Seattle loses, you lose the 62¢. The most you lose is always the price you pay.
The spread and total rows work the same way. Seahawks -3.5 at 47¢ pays $1 if Seattle wins by four or more, and Over 46.5 at 50¢ pays $1 if the teams combine for 47 or more points.
- Chicago’s passing game carries the offense, with Williams completing 71% of his passes, second in the NFL. Luther Burden III posted 130 yards and a touchdown last week.
- Seattle’s defense has allowed just 3.5 yards per carry, second best in the league, so Chicago leans on throws. Quarterback Sam Darnold counters with Jaxon Smith-Njigba.
- Seattle leads the series 12-8 and won the last meeting 6-3 on Dec. 26, 2024. Chicago won the last trip to Seattle, 25-24, in 2021.

Anytime touchdown contracts count every score except passing touchdowns.
Bears vs. Seahawks Prediction 1: Zach Charbonnet Anytime TD, 40¢
Charbonnet led Seattle with 12 rushing touchdowns on 184 carries in 2025, a career high, and he earned a red-zone specialist label. He scored twice on 18 carries against Carolina late last season, and he owns 21 rushing touchdowns in 49 career games. Kenneth Walker now plays in Kansas City, which leaves the short-yardage work with Charbonnet.
Everything points toward a goal-line score tonight. Seattle’s ground game struggled without him, and the Seahawks enter as the home favorite, a script that rewards the run. He practiced fully Thursday and Saturday and carries no injury designation, so Seattle gets its closer back cleared and ready. Expect Charbonnet to cash in when the Seahawks reach the red zone.
Bears vs. Seahawks Prediction 2: Colston Loveland Anytime TD, 30¢
Loveland scored in back-to-back games after a scoreless five-game start. He caught six passes for 65 yards and a touchdown at Atlanta, then seven passes on 12 targets for 69 yards and a score against New England. Kmet’s injury hands him the top tight end job, and Williams threw for over 300 yards without an interception in both games.
Loveland showed his ceiling as a rookie, with two touchdowns in a 188-yard game at Cincinnati and 193 yards across two playoff games, the most by a rookie tight end since at least 1960. A neck issue limited him Friday, but he went full Saturday with no designation. Monangai’s absence pushes Chicago toward the air, and Williams called Seattle a test of patience. Patient offenses live on short, middle-field throws, which is Loveland’s lane. Expect Williams to find him once Chicago gets inside the 20.
