College Football Prediction Market Promos: Trade on Kalshi & Polymarket Today (Sept. 11)

The college football prediction market promos available for Week 2 give new users six different offers ahead of one of the sport’s oldest and most bitter rivalries. Missouri vs. Kansas kicks off tonight at 8 p.m. ET on FOX from David Booth Kansas Memorial Stadium, marking the first Border War played in Lawrence since 2005.

The former Big 12 rivals meet with both teams 1-0 after Week 1 blowouts of FCS opponents. No. 23 Missouri enters as the road favorite behind Ole Miss transfer Austin Simmons, receiver Donovan Olugbode, and a defense returning most of its front seven, while Kansas counters with third-year quarterback Isaiah Marshall, a Lance Leipold offense back under coordinator Andy Kotelnicki, and a home crowd that has waited 21 years for this.

The college football prediction market promos below come from Polymarket, Kalshi, Novig, ProphetX, FanDuel Predicts, and DraftKings Predictions, with offers ranging from a $25 trading bonus to $200 in promotional value.

Best College Football Prediction Market Promos for Missouri vs Kansas

The best six college football prediction market promos all have different details and requirements to claim, so make sure you find the best one that works for you. Without further ado, let’s get into what each of these prediction market apps offer:

1. Kalshi

New users who sign up with the Kalshi promo code LABS can earn $25 in promotional credit, unlocked once they place $25 in qualifying trades. It’s a dollar-for-dollar match with no multiplier to work through, which makes it one of the cleaner offers available for Friday night’s slate.

Tonight’s Border War gives new traders plenty to work with. Kalshi has winner, spread, and total contracts open for Missouri-Kansas. Anyone who thinks Kansas keeps this close in Lawrence but still loses can go that route on the spread side rather than the outright market.

Promo Code	Sign-Up Bonus	States
LABS	Trade $25, Get $25!	AK, AL, AR, CA, CO, CT, DC, DE, FL, GA, HI, IA, ID, IN, KS, KY, LA, ME, MN, MO, MS, NC, ND, NE, NH, NJ, NM, NY, OK, OR, PA, RI, SC, SD, TN, TX, UT, VA, VT, WI, WV, WY

2. Polymarket

The Polymarket promo code LABS works on a different model. There’s no qualifying trade to clear, instead requiring that eligible new users deposit $10 and the $50 trading bonus lands in the account.

That’s useful in a spot like this one, where the outright and spread markets disagree. Polymarket traders have Missouri around 68% to win the Border War outright, but only about 51% to cover a spread of roughly 5.5 points in Lawrence.

3. ProphetX

Of the college football prediction market promos in this roundup, the ProphetX promo code LABSMAX asks the most up front. Eligible new users need $50 in qualifying trades to unlock $75 in promotional credit, which doubles the volume Kalshi requires and is five times Polymarket’s $10 deposit.

The trade-off is the payout. At $75, it’s among the largest fixed rewards here, and a 1.5x return on required volume beats Kalshi’s dollar-for-dollar match. If you were already planning to put $50 through the Missouri-Kansas markets tonight (winner, spread, or total) the higher threshold isn’t really a cost. If you weren’t, one of the lower-entry offers is the better starting point.

LABSMAX	Trade $50, Get $75!	AL, AK, AZ, AR, CA, CO, CT, DE, FL, GA, HI, ID, IL, IN, IA, KS, KY, LA, ME, MD, MA, MI, MN, MS, MO, MT, NE, NH, NJ, NM, NY, NC, ND, OH, OK, OR, PA, RI, SC, SD, TN, TX, UT, VT, VA, WV, WI, WY

4. Novig

The Novig promo code BCLABS turns a $10 qualifying deposit into $25 in trade credits, putting it in the same low-entry tier as Polymarket rather than asking for ProphetX-level volume.

What separates Novig is the structure underneath it. Rather than taking positions against you like a traditional sportsbook, it runs a two-sided exchange where users trade against each other. So, the price you get on Missouri-Kansas tonight depends on what someone else is willing to take the other side at. The catch is availability: Novig is live in fewer states than most of the platforms in this roundup, so confirm you’re in an eligible one before you start the signup.

5. FanDuel Predicts

FanDuel Predicts skips the code entirely. Eligible new users just register through the qualifying FanDuel Predicts promo code link, and the welcome offer attaches to the account automatically, which removes the most common way people accidentally forfeit a bonus.

The limitation is reach. FanDuel Predicts is live in fewer states than any of the other five platforms here, so it’s worth confirming eligibility before kickoff in Lawrence rather than after. If you’re outside the footprint, Kalshi and Polymarket have the widest availability of the group and both have full winner, spread, and total markets open on the Border War.

Missouri vs. Kansas: The Border War Odds, Preview & Prediction

Missouri is the clear favorite across college football odds from major prediction markets, with the winner contract currently priced at 67¢.

Prediction Market	Missouri	Kansas
Kalshi	67¢	34¢
Polymarket	66¢	35¢

A Missouri contract in the upper 60s represents roughly a 66% implied probability that the Tigers win outright. These are market prices rather than fixed sportsbook odds, so they can continue moving as traders enter and exit positions before kickoff. Polymarket traders have also priced Missouri at only about a 51% chance to cover the spread, a much closer call than the outright number.

No. 23 Missouri (1-0) visits Kansas (1-0) tonight (8 p.m. ET, FOX) at David Booth Kansas Memorial Stadium in Lawrence. This is Mizzou’s first trip there in 21 years, and the Tigers haven’t won in Lawrence since 2001. Missouri leads the all-time series 57-55-9 by Kansas’ official count and won last year’s revival meeting 42-31.

Both teams cruised in Week 1, as Missouri handled Arkansas-Pine Bluff 54-14, while Kansas piled up more than 600 yards in a 52-6 win over Long Island University. Both programs are breaking in new starting quarterbacks, and each lost three of its top four wide receivers. 

Ole Miss transfer Austin Simmons was close to flawless in his Missouri debut, completing 17 of 19 passes for 252 yards and four touchdowns with no interceptions, albeit against an FCS opponent. Eli Drinkwitz’s team will be without running back Ahmad Hardy, who is expected to miss the game with an offseason injury. 

Kansas looks different too. Lance Leipold’s staff lost Jalon Daniels to graduation and rehired Andy Kotelnicki to call plays, with Isaiah Marshall making just the third start of his career — and his first real test against a Power Four defense. 

The venue adds a variable, considering this is the first Border War in Lawrence since 2005, and it’ll be played in a limited-capacity venue listed at roughly 32,000 seats, which is a loud, but smaller home-field edge than a full-size Power Four crowd. Kansas has the atmosphere, the more experienced defensive front seven, and a live shot at keeping this inside a touchdown. 

Missouri vs. Kansas Prediction: Kansas +5.5 (~52¢)
