The Green Bay Packers visit the Minnesota Vikings on Sunday, September 13, 2026, at 4:25 PM ET, an NFC North rivalry game under the roof at U.S. Bank Stadium, and the odds on this NFL Week 1 matchup have already done something betting lines rarely do in August: they switched sides. The game opened with Green Bay as a short road favorite back in May. Then Minnesota settled its quarterback question, and by mid-August the consensus line had crossed all the way through zero to Vikings -1.5. Every serious answer to the winner question, the exchange, the consensus books, and a price-blind model panel, now lands within two points of 52% Minnesota, which makes this the closest thing Week 1 has to a pure referendum on one quarterback change. This page tracks the sportsbook line, the Kalshi prices, and the panel side by side, and it refreshes daily through kickoff. The lone dissent in the stack is a single de-vigged book capture that makes Green Bay 50.8%, and how much weight that one number deserves is below.
The Quick Answer
As of the August 19, 2026 capture, Minnesota's winner contract trades at 51/52 cents on Kalshi, which reads directly as a 51-52% chance, with Green Bay at 47/48, and the consensus moneylines (Green Bay -102, Minnesota -118) de-vig to about 51.7% Minnesota, within half a point of the exchange. The early consensus line is Vikings -1.5 with a total of 45.5, after this game opened at DraftKings at Green Bay -1.5 and 44.5 in May. The lone dissent: a same-morning BetRivers capture of Minnesota -110 that the OddsShopper fair-value engine de-vigs to 49.2%, a shade under the coin flip. That spread of answers is a reason to shop the number, not to bet either side blind. The full Kalshi ladder, what flipped the line, and how seriously to take the dissent are below.
Packers At Vikings: Kickoff And The Current Line
The frame first. Green Bay at Minnesota is the late-Sunday window's marquee divisional game of Week 1, September 13 at 4:25 PM ET, indoors at U.S. Bank Stadium. Both teams open their season inside the NFC North, the loser starts 0-1 in the division, and the betting market has spent the whole summer changing its mind about which one that will be.
The prices, as of August 19, 2026:
| Market | Number | Where |
|---|---|---|
| Vikings Moneyline (Captured Quote) | -110 | BetRivers, via the OddsShopper odds screen |
| Vikings Win Probability, De-Vigged | 49.2% | OddsShopper fair-value engine, from the captured quote |
| Consensus Moneylines | GB -102 / MIN -118 | look-ahead book consensus, about 51.7% Minnesota de-vigged |
| Vikings Winner Contract | 51/52¢ | Kalshi |
| Packers Winner Contract | 47/48¢ | Kalshi |
| Early Consensus Spread | Vikings -1.5 | look-ahead line, subject to move |
| Early Consensus Total | 45.5 | look-ahead line, subject to move |
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 organized around, not a live quote from any single book. Game lines twenty-plus days from kickoff move on every roster headline, so treat -1.5 and 45.5 as the market's current center of gravity and shop the live number across every major book before you act on either. The moneyline and the Kalshi prices above are live captures, and the stamp tells you when.
The consensus center of gravity is the story here, because it moved through zero. When the opening numbers posted at DraftKings in May, this game was Green Bay -1.5 with a total of 44.5. On August 11, Minnesota named Kyler Murray its starting quarterback for Week 1, ending the competition with J.J. McCarthy, and the consensus now sits at Vikings -1.5 with the total a point higher at 45.5. The line has traveled three points since May, and the Murray announcement is the biggest single catalyst in that window. Remember that swing, because part of this market never fully bought it, and we get to that below.
The movement log, which this page will keep updating:
| Date | What moved |
|---|---|
| May 14 | Opener posts at DraftKings: Green Bay -1.5, total 44.5 |
| Aug 11 | Minnesota names Kyler Murray its Week 1 starter |
| Aug 12 | Price-blind model panel runs: 52.1% Minnesota against a 52.0¢ market |
| Aug 19 | Consensus Vikings -1.5, total 45.5; Kalshi 51/52; the -1.5 cover rung at 45/47 |
This fixture also has a habit of punishing early-week confidence. We have handicapped Packers-Vikings in Week 1 before: Matt Savoca's breakdown of the 2022 opener had Green Bay favored on the road with a 47-point total, and Minnesota won that game decisively. Different rosters, same lesson: this rivalry's openers rarely follow the summer script.
Kalshi Vs Sportsbook Prices On This Game
This is the part of the page you will not find on a standard odds screen. Kalshi lists this game as three separate event 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 |
|---|---|---|---|
| Minnesota Wins | 51¢ | 52¢ | Moneyline -110 captured at BetRivers (49.2% de-vigged) |
| Green Bay Wins | 47¢ | 48¢ | the other side of the same coin |
| Minnesota Wins By Over 1.5 | 45¢ | 47¢ | the Vikings -1.5 cover, exactly |
| Green Bay Wins By Over 2.5 | 40¢ | 42¢ | the Green Bay -2.5 question, this game's busiest rung |
| Green Bay Wins By Over 3.5 | 33¢ | 34¢ | the Green Bay -3.5 question |
| Over 44.5 Total Points | 49¢ | 51¢ | one point under the consensus number |
| Over 45.5 Total Points | 45¢ | 46¢ | sits right on the consensus 45.5 |
| Over 47.5 Total Points | 38¢ | 42¢ | two points above the consensus number |
The single most interesting row is the third one. "Minnesota wins by over 1.5" settles yes on a Vikings win by two or more, which makes it the exact exchange translation of the consensus Vikings -1.5 cover, and it trades at 45/47. A spread sitting at the market's true center usually prices its own cover much nearer 50% than this, so 45/47 is at least a clue that -1.5 is a shade rich, a favorite by roughly a point rather than the full point and a half. The busiest rung on the ladder by volume, meanwhile, is "Green Bay wins by over 2.5" at 40/42, and the arithmetic around it holds together: the 5-8 cent gap between that rung and Green Bay's 47/48 winner price is the ladder's price for a one-or-two-point Green Bay win. No rung is fighting the others; the whole board is just refusing to move far from even.
The winner market itself is about as tight as this exchange gets: Minnesota's 52-cent ask plus Green Bay's 48-cent ask sums to exactly 100 cents, meaning you can buy either side with no combined premium at the ask. Kalshi's per-contract trading fee, roughly a cent and three-quarters at prices near 50, claws some of that back, but the all-in two-sided cost still comes in under the roughly 4-5% hold built into a standard two-way -110 sportsbook market. On this particular game, and after fees, the exchange is currently the modestly cheaper place to express a winner opinion.

Worked Example: What A Field-Goal Finish Costs In This Game
Here is the ladder arithmetic I keep coming back to on this board, because it prices the game's closeness directly instead of guessing at it. The "Green Bay wins" contract trades at 47/48 cents, and "Green Bay wins by over 3.5" trades at 33/34. The only difference between those two contracts is a Green Bay win by three points or fewer, so subtracting them prices that band on its own:
- Buy the win at the 48-cent ask, strip out the blowout scenarios at the 33-cent bid, and the 15-cent gap is the order book's price for a Green Bay win by exactly 1, 2, or 3 points.
- Work it from the friendlier sides (47 bid vs 34 ask) and you get 13 cents.
- So of Green Bay's roughly 47-48 cents of total win probability, 13 to 15 cents, a quarter to a third of it, lives inside a field-goal margin. The exact-3 slice alone, the gap between the "over 2.5" and "over 3.5" rungs, runs 6 to 9 cents; that slice is precisely the outcome a sportsbook Green Bay -3 pushes on, which is why no single ladder rung maps to -3 and the arithmetic has to price it for you.
That is the market drawing you a picture: a game it expects to be decided by one kick either way. At -1.5, the live key numbers are 1, 2, and 3 together; the ladder prices the one-and-two-point Green Bay margins at 5-8 cents against the 6-9 cent exact-3 slice, and 3 starts governing this line outright only if the spread walks to -2.5 or -3. That walk is exactly when a half point across 3 becomes worth real money while a half point elsewhere is mostly juice, and how key numbers work is the difference between paying for the right one. The same subtraction works on any two neighboring rungs of the ladder above.
What The Market Is Saying
Strip the mechanics away and the numbers are having a genuinely close argument. The consensus line flipped to Minnesota on the Murray announcement. Kalshi's traders agree, barely, at 51/52. And on August 12, the day after Minnesota named its starter, we ran eight AI models over the fetched facts of every Week 1 game, none of them shown a single price, and blended their independent estimates. The panel put Minnesota at 52.1% against a market then sitting at 52.0 cents, a 0.1-point gap that made this the tightest market-vs-model agreement on the entire Week 1 board, with all eight seats landing between 51 and 54 on the Vikings. The models' reasoning matched the market's: Minnesota resolved its quarterback situation with a proven veteran and carried a clean injury sheet, while Green Bay countered with quarterback continuity and the slightly better 2025 point differential. Those are model estimates, not predictions of fact and not financial advice, and the panel's record is graded in public here.
The read in one line: exchange 51/52, consensus books about 51.7 de-vigged, price-blind panel 52.1. Every market-wide measure says Minnesota by a whisker, and the whisker, not the winner, is the story.
The dissenting number deserves an honest label before it deserves any weight. The 49.2% is one book's captured quote, Minnesota -110 at BetRivers, run through one engine; the consensus moneylines de-vigged land at roughly 51.7% Minnesota, agreeing with the exchange almost to the tick. So treat the 49.2 as a tripwire rather than a co-equal voice: it is the kind of quote that surfaces when at least one book has not fully ratified a move. The subtler tell sits on the exchange itself. The spread ladder prices Minnesota's -1.5 cover at 45/47, under the coin flip, a hint that the order book sees a favorite by roughly a point rather than the full point and a half. A quarterback upgrade on paper is worth points; whether Murray's September version is worth all of the three this line has traveled, off a one-year deal in a new offense, is precisely the open question this page will watch the money answer.
The total is telling a quieter story. Its number, the consensus 45.5, sits a point above May's opener, and Kalshi's ladder quietly shades under it: the heavily traded rung on the consensus 45.5 itself sits at 45/46, and the much thinner 44.5 rung trades at 49/51, so the exchange's fair total lands a touch under the consensus number. Two points higher, the over on 47.5 drops to 38/42. Split 45.5 points along a -1.5 spread and the market is penciling in something like 23.5 for Minnesota and 22 for Green Bay, two efficient-but-unspectacular team totals in a dome where weather will never be an excuse. Whichever offense proves that projection wrong first will move both boards at once, starting with the season-long ones: the market's view of Minnesota's 2026 win total and Green Bay's win total each lean hard on who owns the NFC North, and the Vikings' and Packers' playoff chances boards will re-price on this result before Week 2 practice opens.
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. (Weather is not one of them; this game is indoors, which is exactly why the total's argument is about the offenses and nothing else.)
Murray's integration, in public. The market has already paid for the veteran-quarterback upgrade; the evidence phase decides whether it stays paid for. Murray debuted in Minnesota's preseason win over the Giants in an offense that hands him Justin Jefferson, Jordan Addison, and T.J. Hockenson, and the real watchpoint is whether the timing with those three looks clean enough, quickly enough, to justify the full three points this line has traveled since May. Clean buildup and the -1.5 firms; anything ragged and this line drifts back toward the zero it just crossed.
The walk toward 3. A -1.5 consensus in a division game has two magnetic destinations, pick'em and -3, and the gap between them is the most valuable stretch of spread real estate in football. The earliest public signal is usually not a sportsbook line move but the exchange: watch whether Kalshi's "Minnesota wins by over 1.5" rung climbs off its 45/47; exchange ladders often re-price before every book has adjusted. If Minnesota reaches -2.5 or -3, the half points start costing real money in both directions.
Which side the late money takes. The flip means everyone's summer opinion of this game was formed at Green Bay -1.5, and stale opinions meeting a moved line is where closing-week flow comes from. If the winner market holds in the low 50s while the spread stalls short of -2.5, the market is calling this a one-point game no matter what the August headlines said, and patient shoppers on either side will keep getting playable numbers into the weekend.

Packers Vs Vikings Odds: FAQ
Why is a Kalshi price also a probability? Each contract pays $1 if the outcome happens. Pay 52 cents for "Minnesota wins" and, before Kalshi's trading fee, you break even exactly when the Vikings win 52% of the time, so the price is the market's probability, no conversion table needed. Our full Kalshi NFL guide covers order types, fees, and settlement.
Is this game Vikings -1.5 or a pick'em? Depends which market you ask, which is the point of this page. The look-ahead consensus says Vikings -1.5. Kalshi's winner market says 51/52, barely Minnesota, and the consensus moneylines de-vig to about 51.7% the same way; one book's captured quote de-vigged even dipped to 49.2, barely Green Bay. On the exchange you choose your margin directly: "Minnesota wins by over 1.5" (45/47 cents) is exactly the Vikings -1.5 cover, and "Green Bay wins by over 2.5" (40/42) is the Green Bay -2.5 question. A book's -3 pushes on a three-point margin, which the ladder instead prices as its own 6-9 cent slice.
Why do Kalshi prices differ from sportsbook odds? A sportsbook sets a line and charges vig on both sides; a standard two-way market at -110 each way carries roughly a 4-5% hold. Kalshi is an exchange where traders set prices against each other, and this game's winner market currently sums to 100 cents at the ask before the exchange's trading fee. Different plumbing, which is why the de-vigged fair number rather than a raw moneyline is the honest comparison, and right now the consensus de-vig and the exchange agree within half a point; the outlier is a single book's captured quote.
When will this line move? Quarterback evidence, first. The line already made its big move when Minnesota named Kyler Murray the starter, so the remaining catalysts are how the new offense looks in the buildup, both teams' injury reports as September opens, and the final designations the weekend of the game. The inactives land roughly 90 minutes before the 4:25 PM ET kickoff, and this line will have finished its entire journey by then.

The Bottom Line
This game's odds have already lived a full life: favorite Green Bay in May, a quarterback announcement in August, and now a market where the exchange says 51/52 Minnesota, the consensus books de-vig to about 51.7, and a price-blind panel said 52.1, with one stray book capture dipping to 49.2. Every serious answer sits within a nickel of a coin flip, stacked against a consensus line of Vikings -1.5 that the exchange's own ladder prices as a shade rich. Between now and September 13, this page will record which way that argument resolves, one practice report and one ladder tick at a time.
