Patrick Mahomes gets another primetime matchup in front of a full Arrowhead crowd, and plenty of Colts vs. Chiefs prediction promos will get you through the night.
Colts vs. Chiefs goes down at Arrowhead Stadium for the Sunday Night Football matchup on NBC (8:20 p.m. ET), and the setup is two quarterbacks working their way back from major injuries. The Chiefs opened with a 31-10 rout of Denver on Monday night in Mahomes' return from a torn ACL, a response they needed after a 6-11 finish and their first missed playoffs since 2014. The Colts arrive 0-1, coming off a 41-23 loss to Baltimore, with Daniel Jones starting after averaging 4.5 yards per attempt in his Colts debut while still working back from the Achilles injury that ended his 2025.
Below are the best Colts vs. Chiefs prediction market promos for the game, the welcome offers live at each one right now, and how traders are actually pricing Colts–Chiefs heading into kickoff.

Colts vs. Chiefs Pricing on Prediction Markets
| Market | Indianapolis Colts | Kansas City Chiefs |
|---|---|---|
| Moneyline | ~28% | ~72% |
| Spread | +5.5 (~50%) | -5.5 (~51%) |
| Total | Over 46.5 Points (~5o%) | Under 46.5 Points (~51%) |
Kickoff for Colts vs. Chiefs is at 8:20 p.m. ET on Sunday, September 20, 2026. Always check a notable prediction market app for the latest pricing before the game begins.
As of the weekend, Sunday Night Football is priced at Colts 28% and Chiefs 72%. Some outlets have the Colts trading at $0.28 per share on Kalshi, making the Chiefs one of the heavier favorites on the Week 2 board, though nowhere near the top: San Francisco is the week's strongest favorite at 90% against Miami.
That's a meaningful repricing off one week of football. Kansas City has climbed from an opening spread of -5.5 to -6.5, then back down to -5.5 in some markets, while the total has dropped from 47.5 to 46.5. A -285 moneyline strips down to roughly 74% on a vig-free basis, so the prediction markets and the sportsbooks largely agree on the headline number.
The interesting wrinkle is the split between tickets and money. Kansas City hasn't moved through the key number of seven despite attracting most of the spread bets and money, but Indianapolis has drawn 75 percent of the moneyline handle on only nine percent of moneyline tickets. On an exchange, that kind of divergence shows up in the order book instead of being hidden behind a bookmaker's number, which is a fair argument for trading this one on a prediction market app instead of a sportsbook.

Best Colts vs. Chiefs Prediction Market Promos
1. Polymarket
| Promo Code | Sign-Up Bonus | States |
|---|---|---|
| Click Here | Deposit $10, Get a $50 Trading Bonus! | 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 |
Nothing else on this page gets you to a live position faster. The Polymarket promo code requires a $10 deposit and no qualifying trade, meaning you don't have to commit to a side in Kansas City just to unlock the money. Fund the account, and you'll have $60 before the 8:20 p.m. ET kickoff.
Because the $50 lands as flexible trading credit rather than a one-and-done ticket, it doesn't expire with this game. Pick up Chiefs shares in the mid-70s, sell into a two-score third-quarter lead, and the same balance is still there for Monday night's Giants–Rams card or next Sunday's slate, without reaching for your wallet again.
2. Kalshi
| Promo Code | Sign-Up Bonus | States |
|---|---|---|
| Click Here | Trade $25, Get $55! | 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 |
The Kalshi promo code returns $55 once you've traded $25 worth of contracts. The requirement tracks volume, not deposits, so it doesn't matter whether your positions win or lose. Each one counts toward clearing the bar, and a winner just leaves you with a larger bankroll heading into the next trade.
You can clear the whole thing on Sunday night without stretching for a single large position. Place $10 on the Chiefs spread, $10 on the under, and $5 on a Kenneth Walker III anytime touchdown after his 173-yard rushing night against Denver, and you're done before the third quarter kicks off. Kalshi also runs the widest per-game board of any platform listed here, and with the season two weeks old, its season-long markets are still moving: the Chiefs trade at $0.14 to win the AFC Championship and $0.07 to win the Super Bowl.
3. Novig
| Promo Code | Sign-Up Bonus | States |
|---|---|---|
| Click Here | Deposit $10, Get $25 in Trade Credits! | AK, AR, FL, GA, HI, IL, IN, IA, KS, KY, ME, MA, MN, MO, NE, NH, NC, ND, OH, OK, OR, SC, SD, TX, VT, VA, DC, WI, WY |
The Novig promo code unlocks on the deposit itself, with no qualifying trade required, making it the low-friction option if you're opening an account while the pregame show is already on. $10 in becomes $35 of usable balance, and you can call it seven $5 positions across the Colts vs. Chiefs board.
What separates Novig is how it charges you, or rather how it doesn't. It's sports-only, takes no vig on pregame markets, and layers on rewards that scale with your trading volume rather than capping it. The order-book feature is the part worth learning: you can set your own price and wait for someone to take the other side. If you like Jonathan Taylor to clear his rushing number but not at the price on the screen, list your own and let the market come to you instead of paying up.
4. ProphetX
| Promo Code | Sign-Up Bonus | States |
|---|---|---|
| TANBONUS | 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 |
The ProphetX promo code TANBONUS asks the most of you and gives the most back: $75 in bonus credit once you've cleared $50 in volume. It doesn't have to come from one position, so 10 $5 trades across the Sunday night board clear the bar just as cleanly as a single $50 swing on the Chiefs' moneyline.
ProphetX is built for sports and carries nothing else, so you won't scroll past election or inflation contracts to find the Colts vs. Chiefs market. Instant cash-out is the underrated feature, as you can exit a position and the capital is available immediately, rather than tied up waiting on settlement. That matters more than usual in a game with rain in the forecast, where one weather-driven possession can swing a total. The platform also reaches most states, including a handful where no legal sportsbook operates.
5. FanDuel Predicts
| Promo Code | Sign-Up Bonus | States |
|---|---|---|
| Click Here | Trade $1 for 5 Days, Get $100 Bonus! | AK, AL, CA, DE, FL, GA, HI, ID, MN, ND, NE, NM, OK, RI, SC, SD, TX, UT |
There's no FanDuel Predicts promo code to remember and no waiting period to clear, as the offer attaches automatically to eligible new accounts, removing the most common way people accidentally forfeit a bonus. $1 on Sunday's NFL board starts the streak, Monday night's Giants–Rams game covers day two, and a dollar on the Super Bowl or MVP market covers the quiet midweek stretch until Thursday night.
Turning $5 into $100 offers the best return per dollar on this page, with one condition: you have to show up on five separate days. Miss one and the counter resets to zero. The interface is close enough to the FanDuel sportsbook that first-time contract traders have little to no learning curve, and existing FanDuel customers can bypass verification altogether. It's also live in a number of states where traditional sportsbooks still aren't, which is the main reason to keep it on your list even if you already have two or three accounts open.
