The 2026 NFL season opens on a Wednesday night with the game the schedule makers could not resist: the New England Patriots at the Seattle Seahawks, September 9 at Lumen Field, a rematch of Super Bowl LX seven months after Seattle won it 29-13. The odds on this game carry a tension you can read right off the board. The champion is at home and favored. But the team it beat went 14-3 last season with the MVP runner-up at quarterback, and every venue with real money on the line prices this closer to a toss-up than a coronation. This page tracks the sportsbook line, the Kalshi exchange prices, and a third number that disagrees with both of them, and it gets refreshed daily through kickoff, because a look-ahead line sitting half a point above the most important number in football never stays quiet for long.
The Quick Answer
As of the August 19, 2026 capture, Seattle's winner contract trades at 63/65 cents on Kalshi, which reads directly as a 63-65% chance, while the best moneyline on the Seahawks is -182, and de-vigging the full market lands the fair number at 64.0%. The early consensus line has Seattle -3.5 with a total of 44.5, and Kalshi prices the over on that same 44.5 at 48/49 cents, a near coin flip. The full ladder, the price of the number 3 in this specific game, and our price-blind model panel's dissenting 57% are below.
Patriots At Seahawks: Kickoff And The Current Line
The frame first. New England at Seattle is the season opener, Wednesday, September 9, 2026, 8:20 PM ET at Lumen Field. The banner-raising game, except the team standing on the visiting sideline while the banner goes up is the team Seattle took it from.

One label on that table matters more than the numbers. The spread and total are the look-ahead consensus, the early number the market is orbiting, not a live quote from any single book. The camp reports, joint practices, and injury designations between this capture and kickoff can each move it, so treat -3.5 and 44.5 as the market's starting point and shop the live number across every major book before you act on either. That screen lines up the major sportsbook and exchange prices on one row next to the fair number, and our real-time NFL odds guide covers how to read it. The moneyline and the Kalshi prices above are live captures, and the stamp tells you when.
The de-vigged 64.0% is the better single answer to "what does the market actually think" than the raw -182. The -182 is the single best price on the board, not the middle of it; at this capture it comes from NoVig, an exchange-model venue that is not live in every state. The 64.0%, by contrast, is built by de-vigging the whole board the odds screen carries, traditional sportsbooks and newer venues together. And it is worth sitting with how close that 64.0% lands to Kalshi's 63/65. A de-vigged consensus across every venue on the screen and a single exchange's open order book are two different price-discovery machines, and on this game they converge on the same probability to within a cent, though the de-vigged board already includes exchange-model venues, so read it as one broadly shared view rather than two strangers agreeing. Either way, the one number that won't fall in line, our price-blind model panel, is two sections down.
Kalshi Vs Sportsbook Prices On This Game
This is the part of the page a standard odds screen will not give you. New to event contracts? How prediction markets work covers the mechanics from zero. Kalshi lists this game as three separate markets: a winner market, a spread ladder, and a total ladder. Prices are in cents per contract, each contract pays $1 if it settles yes, so a price is a probability. All quotes as of August 19, 2026.
| Kalshi Market | Bid | Ask | Sportsbook equivalent |
|---|---|---|---|
| Seattle Wins | 63¢ | 65¢ | Moneyline -182 best price (64.0% de-vigged) |
| New England Wins | 35¢ | 36¢ | the other side of the same coin |
| Seattle Wins By Over 2.5 | 60¢ | 61¢ | roughly Seahawks -2.5 (win by 3 or more) |
| Seattle Wins By Over 3.5 | 49¢ | 50¢ | the -3.5 cover question, a shade under even |
| Seattle Wins By Over 4.5 | 44¢ | 45¢ | roughly Seahawks -4.5 |
| Over 43.5 Total Points | 52¢ | 56¢ | the total's lower neighbor |
| Over 44.5 Total Points | 48¢ | 49¢ | sits right on the consensus 44.5 |
| Over 45.5 Total Points | 44¢ | 49¢ | the total's upper neighbor |

The single most interesting row is the fourth one. "Seattle wins by over 3.5" at 49/50 cents is the exchange's translation of the Seahawks -3.5 cover question. A fairly hung spread always trades near 50 cents, because that is what a spread is, so the information is in which side of even it sits: at 49/50, Seattle's cover sits a shade under it. One rung up the ladder, "Seattle wins by over 2.5," the -2.5 question, trades all the way at 60/61. Those two rungs bracket the key number 3, and when one point of spread moves a contract roughly 10 to 12 cents, you are standing on the most common final margin in football, and that is precisely when knowing how key numbers work stops being trivia and starts being the whole decision.
The winner market is where the liquidity lives: Seattle's 63/65 quote is two cents wide, and the further you climb either ladder, the thinner the order books get, until the quotes stop meaning much.

Worked Example: What Landing Exactly On 3 Costs In This Game
Here is the ladder arithmetic worth redoing on this specific board, because it prices the key number directly instead of guessing at it. "Seattle wins by over 2.5" trades at 60/61 cents. "Seattle wins by over 3.5" trades at 49/50. The only difference between those two contracts is a Seahawks win by exactly three points, so subtracting them prices that single outcome:
- The 61-cent ask on "over 2.5" against the 49-cent bid on "over 3.5" leaves a 12-cent spread, and that spread is what the order book charges for the exact-3 margin.
- Worked from the friendlier sides, the 60 bid against the 50 ask, it is 10 cents.
- So this market currently prices a Seattle win by exactly 3 somewhere around 10-12%, an enormous amount of probability stacked on one exact margin. That margin is the outcome that pushes at -3, and it is exactly why 3 is the most fought-over number in the sport.
One honest caveat before you use that number: these are quotes, not fills. Taken literally, the same ladder leaves only three or four cents for a Seattle win by exactly one or two points, the winner market at 63/65 against "wins by over 2.5" at 60/61, and that is thinner than any margin model would sign. The deep rungs of a September order book are thin, so read the 10-12 cents as the band the market will trade at, not as a calibrated probability.
That arithmetic is still the practical answer to the question every bettor on this game faces in the run-up to kickoff: what is the number 3 actually worth on this board? Be precise about what the 10-12 cents buys, because the ladder prices a full point. Moving from Seattle -3.5 all the way to -2.5 turns a three-point Seattle win from a loss into a win on your ticket, and that full point is worth the whole 10-12 cents. The half point a book will actually sell you at the window, -3.5 to -3, only turns that margin into a push, which is worth roughly half of the band, call it 5 to 6 cents. Price a half-point buy against that 5 to 6, still several times what a half point away from a key number carries, and pay for it only when the book charges less. The rungs, not the rule of thumb, tell you what your half point buys.
It is also exactly the comparison OS Pro automates on every line of this game: each book's live price stacked against a fair, de-vigged probability, so you can see which side of 3 is actually worth paying for before you pay it. The code NESEA20 takes 20% off your first payment.
What The Market Is Saying
Strip the mechanics away and the numbers above all say one sentence: the market believes in the champion at home, but it prices the loser of that Super Bowl as a fully live underdog. A 63-65 cent home favorite in a rematch the home team won by sixteen is not a statement of dominance. It is respect for the team on the other sideline.
The respect is earned in the record. New England went 14-3 last season, Drake Maye led the NFL in EPA per play and finished MVP runner-up, and Mike Vrabel won Coach of the Year in his first season in charge. The one game that ended that run is the one being replayed here: Mike Macdonald's defense held that offense to 13 points in the Super Bowl, and its core returns largely intact. Seattle's own offseason cuts the other way. Sam Darnold is coming off a 4,048-yard, 25-touchdown career year, but the coordinator who built that offense, Klint Kubiak, left to become the Las Vegas Raiders' head coach, and Seattle is betting that Brian Fleury, the longtime San Francisco assistant the Seahawks promoted to replace him, keeps the scheme's gains without the voice that installed it. A champion returning its defense but re-wiring its offense, against the quarterback who led the league in EPA per play a year ago: that is what a 3.5-point line with no cushion under it looks like in prose.
The read in one line: every venue makes Seattle a real favorite, none of them makes it a big one, and the distance between "champion at home" and "only a 64% favorite" is the market's honest respect for a 14-3 opponent.
There is a third opinion on this game, and it is the most skeptical one on the page. On August 12, 2026, we ran eight AI models over the fetched facts of the Week 1 board, none of them shown a single price, and blended their independent estimates. After a revision round in which the seats read each other's anonymized reasoning, the panel's blended number on Seattle was 57%, with all eight seats landing between 55 and 58, while the market sat at 64 cents. That tightness without a price anchor is the part worth taking seriously: the usual failure mode of a blind panel is scatter, not consensus, and this one converged. The seats' own stated drivers were quarterback certainty and regressed 2025 point differential, with home field a smaller lift, and on those inputs they put the champion a full seven points closer to a coin flip than the money does. Those are model estimates, not predictions of fact and not financial advice, and the panel's record is graded in public here. But when the books and the exchange agree at 64 and the blind panel says 57, the daily refresh of this page has its job: watching which of them the money migrates toward as the practice reports land.
The three opinions, side by side:
| Who Is Pricing It | Seattle to win |
|---|---|
| Sportsbooks, De-Vigged Across The Market | 64.0% |
| Kalshi Winner Contract | 63¢ / 65¢ |
| Price-Blind 8-Model Panel (Aug 12) | 57% |
Market rows captured August 19, 2026; panel run August 12, 2026.
The total tells a quieter version of the same story. An early consensus of 44.5 sits mid-range for an opener, and Kalshi's ladder hugs it: the over on 44.5 trades at 48/49, a genuine toss-up. Read that off the tight rung only, though. The 44.5 quote is one cent wide, while its neighbors at 52/56 and 44/49 are four to five cents wide, and the 45.5 ask matching the 44.5 ask is a stale-quote tell, so the edges of this ladder are decoration, not evidence. The tight middle says the market expects points, just not fireworks, from a September evening in Seattle between a top defense and an offense breaking in a new play-caller.
Both of these teams also carry season-long numbers this game will immediately re-price. The market's view of New England's 2026 win total and Seattle's win total each lean on how real last season's versions of these teams still are, and the Patriots' and Seahawks' playoff chances boards will move on a Wednesday-night result before any other team has played a snap.
What To Watch Between Now And Kickoff
The daily refresh of this page will track three things, in order of how hard they can move the number.
The injury and practice reports. This far out, the line is priced off two healthy rosters, and that is the fragile assumption. The fault lines in this particular game: Drake Maye's availability is most of New England's number, Seattle's edge rests on the returning core of the defense that held that offense to 13 points, and the Seahawks are breaking in a play-caller whose first live test is this kickoff. The earliest honest signal usually shows up in the practice-participation lists before it shows up in a line move; the inactives land roughly 90 minutes before kickoff, and this line will have finished its entire journey by then.
The boundary at 3. At this capture the consensus sits at -3.5 with the exchange pricing the cover a shade under even. Watch whether the Kalshi rung "Seattle wins by over 3.5" holds its 49/50: exchange ladders can re-price before every book has adjusted, so that rung slipping toward the mid-40s would be the earliest public signal of -3.5 wanting to become -3, and the worked example above already told you what that half point is worth.
Which way the opener money drifts. A standalone season opener is the only NFL game on the board that night, and a solo national broadcast concentrates recreational volume on one line. There is also no long betting week here: with a Wednesday kickoff, whatever public flow arrives will land compressed into the final couple of days, so any drift will be fast when it comes. The measurement of it is this page's daily capture stamps, which will show in public which way this particular number actually moves between now and kickoff, and the worked example above already prices what any move across 3 is worth.

Patriots Vs Seahawks Odds: FAQ
What are the Patriots vs Seahawks Week 1 odds? Seattle is the early favorite in the 2026 season opener. The look-ahead consensus line is Seahawks -3.5 with a total of 44.5, the best current moneyline on Seattle is -182 (at NoVig, an exchange-model venue not available in every state), and Kalshi's winner market trades Seattle at 63/65 cents. Game lines this far out move on every camp headline, so shop the live number before acting on any of them.
Why is a Kalshi price also a probability? Each contract pays $1 if the outcome happens. Before fees, paying 65 cents for "Seattle wins" means you need the Seahawks to win about 65% of the time to break even, so the price reads as the market's probability, no conversion table needed. Our Kalshi NFL guide covers order types, fees, and settlement.
Is Seattle -3.5 or -3 against the Patriots? The look-ahead consensus is -3.5, and Kalshi's ladder shows why that half point is the whole fight: "Seattle wins by over 3.5" trades at 49/50 cents while "Seattle wins by over 2.5," the -2.5 question, trades at 60/61. Those rungs bracket the key number 3, and the roughly 10-12 cent gap between them is the price of Seattle winning by exactly three, the margin that pushes at -3 and the most common final margin in football.
What time is Patriots vs Seahawks and where is it played? Kickoff is Wednesday, September 9, 2026 at 8:20 PM ET, which is 5:20 PM Pacific, at Lumen Field in Seattle. It is the first game of the 2026 NFL season and a rematch of Super Bowl LX, which Seattle won 29-13.
Does this page stay current? Yes. Prices are re-captured and the page rebuilt daily through kickoff, and every table carries its capture stamp. If a number here disagrees with the live odds screen, trust the screen, it updates continuously.

The Bottom Line
Start where this page started: a champion raising a banner in front of the team it beat. On the winner question, the venues are in rare agreement, the de-vigged market at 64% and Kalshi trading 63 to 65, and the only dissent on the page is the price-blind panel at 57, which makes the moneyline a bet on whether the traders or the blind models have this one right. The spread is a different animal. Nothing about -3.5 is settled: the cover trades a shade under even, the exact-3 margin carries 10 to 12 cents of the ladder all by itself, and the run-up to the first Wednesday kickoff of the season is the story of which side of the key number 3 this line finally hangs on. The spread, in other words, is a price question more than a football question, and whichever side of it you land on, the one unforced error available here is paying a worse price than the market is offering somewhere else. That one is entirely avoidable.
