New traders who register with the Kalshi promo code ACTION55 can use their $55 bonus on a Sunday Night Football prediction for the Colts vs. Chiefs matchup at 8:20 p.m. ET on NBC. All you need to do is register for an account using our promo code, make $25 worth of trades, and once they settle, you'll get a $55 bonus. Kalshi stepped up in a big way for the start of the NFL season, with a welcome offer more than double what they previously offered.
Tonight's SNF matchup showcases two of the most interesting teams in the AFC, as they wound up at opposite ends of the spectrum after Week 1: Kansas City dominated Denver at home, while Indianapolis struggled early against Baltimore and never recovered. That said, the odds are moving in favor of the Colts at +6.5, and some offerings even show +6.
Kalshi operates as a CFTC-regulated prediction market, meaning you trade contracts against other users rather than a sportsbook, and a single $25 position on our Sunday Night Football prediction clears the whole requirement.
5 Steps to Claim the Kalshi Promo Code
Signup takes roughly five minutes on a phone, and the bonus hits your account about 12 to 24 hours after you clear the $25 threshold. You never need one $25 trade either, since smaller positions across NFL markets stack toward the same number. Knock it out before the 8:20 p.m. ET kickoff at Arrowhead Stadium and put the credit to work on your own Sunday Night Football prediction:
- Tap the claim link and download the app
- Register with your name, address, phone number, and SSN
- Enter the Kalshi promo codeACTION55 during signup
- Deposit at least $10
- Trade $25 in contracts, including Colts vs. Chiefs
Kalshi Promo Code Eligibility and State Availability
Anyone 18 or older qualifies, which undercuts the 21-year-old minimum most sportsbooks enforce. Federal oversight from the CFTC also stretches the exchange's footprint well past where legal online sportsbooks operate, reaching states such as California, Texas, and Georgia.
Ongoing court cases still block sports event contracts in Arizona, Illinois, Massachusetts, Maryland, Michigan, Montana, Nevada, Ohio and Washington. Confirm your state on Kalshi before claiming the bonus.
Sunday Night Football: Colts vs. Chiefs Odds, Preview & Prediction
| Team | Spread | Moneyline | Total Points |
|---|---|---|---|

| Kansas City Chiefs | -6.5 (49%) | 72% | Under 46.5 (52%) |
Colts vs. Chiefs kicks off at 8:20 p.m. ET on Sunday, September 20, 2026. Always check Kalshi for live pricing leading up to the start of the game.
Kansas City opened as a 6.5-point favorite, and the number has seen a little movement going to -6 in some markets. The moneyline reads -300 on the Chiefs against +240 for Indianapolis, and contract prices in cents track those same probabilities. Watch the board late, because a Chris Jones calf designation and thunderstorms in the Arrowhead forecast both shape this Sunday Night Football prediction.
On Monday night, KC looked ruthless in a 31-10 dismantling of Denver, with Eric Bieniemy back as coordinator and Kenneth Walker III impressing his new teammates mightily. Indianapolis went the opposite direction in a 41-23 home loss to Baltimore, where Daniel Jones averaged 4.5 yards per attempt in his first start back from an Achilles injury. Jonathan Taylor still pounded out 98 yards on the ground with two scores on 19 carries, and Tyler Warren found the end zone, so the Colts keep a clear identity even with the passing game stuck in the mud.
Take Indianapolis and the points. These two met at this same stadium last November, and Kansas City needed overtime to escape 23-20, a three-point margin that lands comfortably inside this number. Storms in the forecast, plus a Chiefs offense leaning on Walker, both point to a slower, grinding script, and short games protect underdogs getting close to a touchdown. Taylor shortens it further every time Shane Steichen leans on him, and Bieniemy's run-heavy Week 1 approach hands Indianapolis exactly the clock control it wants.
