Missouri Tigers the Heavy Favorite in Halloween Matchup
Missouri heads to Fayetteville on Saturday, October 31 as a significant favorite over Arkansas, and the odds across books make that consensus clear. The Tigers are priced between -357 and -500 on the moneyline depending on where you shop, while the Razorbacks range from +275 to +317. The spread at FanDuel has Missouri laying 9.5 points, with the Tigers at -122 and Arkansas at +100. For an SEC matchup on Halloween afternoon, this line tells a straightforward story: the books expect Missouri to win, and to win by more than a touchdown.
What the Missouri vs. Arkansas Moneyline Odds Imply
Converting moneyline prices into implied win probabilities helps frame the market precisely. Missouri's -385 at FanDuel implies roughly a 79% chance of winning. At Kalshi, the -357 price softens that to around 78%. At Paddy Power, the -500 line pushes Missouri's implied probability above 83%. Arkansas's best number, +317 at Kalshi, implies about a 24% chance for the Razorbacks.
If you want to run those numbers yourself, the Odds Converter translates any price into implied probabilities or decimal odds quickly.
The range across books is worth noting. Paddy Power's -500 on Missouri is nearly 150 cents steeper than Kalshi's -357 on the same bet. Shopping lines on a heavy favorite matters more than it often gets credit for, because the difference between -357 and -500 represents a meaningful gap in how much you risk to win the same amount.
Line Shopping the Razorbacks
For Arkansas backers, Kalshi is offering the best price at +317, roughly 40 cents better than Paddy Power's +275. That gap is substantial. On a $100 bet, the difference between +275 and +317 is $42 in potential profit. FanDuel and Unibet both sit at +300, making Kalshi's +317 the clear outlier in the Razorbacks' favor. Bettors backing the underdog should prioritize Kalshi here.
The Spread and Total
The 9.5-point spread at FanDuel reflects a game where Missouri is expected to control the outcome. The plus money available on Arkansas at +100 for the spread means you're getting even money to back a team receiving nearly 10 points at home, a meaningful entry point for bettors who like backing home dogs to cover.
The total is set at 48.5 at FanDuel, with both the over and under at -110, suggesting no strong lean from the book in either direction. That number can move quickly based on weather conditions in Fayetteville, quarterback or receiver injury reports, and each team's recent defensive form.
Key Factors to Watch Before Kickoff
Several things could shift this line before the 4:45 PM CT kickoff on October 31.
Quarterback health. Any uncertainty around Missouri's starting quarterback or offensive line depth would likely compress the spread and soften the moneyline. The same applies to Arkansas if their signal-caller is compromised.
Weather. Late-October afternoons in Fayetteville can bring cold and wind, which tends to suppress scoring and favor the under. Monitor the forecast as the week progresses.
Recent form. Missouri coming off a strong performance or Arkansas following a rough stretch could push the spread past 10 before kickoff. Use Line History to track how this number evolves across books.
Home field. Playing in front of their own crowd on Halloween carries some value for the Razorbacks, even if the books aren't reflecting much of it. Home underdogs in the SEC cover at a respectable historical rate, and this setup fits that profile.
Shopping This Market
With a nine-day window before kickoff, there's time to monitor this line rather than locking in immediately. The moneyline disparity between Paddy Power and Kalshi on the Missouri side is already notable, and spreads and totals could shift as Saturday approaches. Tracking those moves gives you a better chance of finding value on whichever side you like.
