Seattle is the favorite to open the 2026 NFL season against New England, and the price looks right. As of August 16, Kalshi priced the Seahawks near 64 cents to win. Our price-blind AI model panel put them at 63%. If you came here hoping the opener was mispriced, it was not.
The game is Wednesday, September 9 at Lumen Field, a rematch of February's Super Bowl LX, which Seattle won 29-13 over this same Patriots team.
The Board
Prices are Kalshi's order book as of August 16, 2026. The panel column is the blend of five models, none of them shown the market price.
| Outcome | Context | Kalshi market | AI panel blend |
|---|---|---|---|
| Seattle Wins | Home, reigning SB LX champion | 64¢ | 63% |
| New England Wins | Road, SB LX runner-up | 36¢ | 37% |
Kalshi's contract pays out if the named team wins, so 64 cents is simply a 64% chance. Kalshi is a CFTC-regulated event-contract exchange; trading is 18+ and availability varies by state.
All five seats landed within a point of each other, and a second anonymized round, where each model read the others' reasoning, moved the blend less than a point. These are model estimates, not predictions of fact and not financial advice. Every number here is graded in public once the game settles, on the full graded scoreboard.
Why Seattle Is The Favorite
Seattle is the defending champion, it is at home in one of the league's loudest buildings, and it beat this exact opponent on the sport's biggest stage a few months ago, holding New England scoreless through three quarters. Home field alone is worth close to a field goal in the NFL. Sportsbooks opened Seattle as a 4-to-4.5-point favorite, and the panel's blend sits inside the win chance that spread implies.
The Seahawks did lose talent. Super Bowl MVP running back Kenneth Walker III left for Kansas City, and the secondary lost cornerback Tariq Woolen and safety Coby Bryant. The core that won a title is intact, and good teams rarely stop being good over one offseason.
Can New England Beat The Number?
The panel would not push New England below the mid-30s, and the roster is the reason. Drake Maye finished 2025 as the MVP runner-up behind Matthew Stafford, and New England spent the offseason arming him: A.J. Brown and Romeo Doubs at receiver, Alijah Vera-Tucker on the offensive line, plus Carlton Davis III, Dre'Mont Jones and Kevin Byard on defense. On paper this roster is more complete than the one that reached the Super Bowl.
The caution is the schedule. New England's 14-win 2025 came against a last-place slate, and the 2026 schedule is a first-place gauntlet, so some regression is baked in whatever the added talent does. A 4-point road dog splits that difference about right, and the panel landed there too.
What Would Move The Price Before Kickoff
A confirmed absence for Drake Maye or one of his new receivers would push Seattle up several points. Another loss in Seattle's already-thinned secondary would nudge New England toward 40%. And if the point spread drifts off 4.5 in either direction before Wednesday, new information has arrived. Week 1 inactives post about 90 minutes before kickoff.

The Bottom Line
If you want Seattle, the 64-cent price from August 16 was fair, and the only reason to wait is the injury report. If you want New England, you are backing Drake Maye's new weapons against a champion at home, and the panel gives that about a one-in-three shot. We grade this call in public the moment the game ends.
