Current prices are approximately:
- Kansas City Chiefs: 72%
- Indianapolis Colts: 28%
Kalshi and Polymarket are showing almost identical win probabilities, giving the Sunday Night Football matchup an unusually clear market consensus.
Those percentages are trading prices rather than guarantees.
NFL game markets can move throughout Sunday as injuries, lineup news and trading activity change before kickoff.
Chiefs Opened the Season With a 31-10 Win
Kansas City enters Week 2 after one of the more convincing performances of opening weekend.
The Chiefs beat Denver 31-10 on Monday night to begin the season 1-0.
The result matters to Kansas City's broader season markets as well.
Kalshi currently gives the Chiefs approximately:
- 63% chance to make the playoffs
- 34% chance to win the AFC West
- 12% chance to win the AFC
- 6% chance to win the championship
Those markets provide another reason Sunday night's game matters beyond the Week 2 standings.
A move to 2-0 would strengthen Kansas City's position in a competitive AFC West.
Colts Try to Rebound From 41-23 Loss
Indianapolis enters Sunday night from the opposite direction.
The Colts lost their opener to Baltimore 41-23 and begin Week 2 at 0-1.
Kalshi currently prices Indianapolis at:
- 30% to make the playoffs
- 16% to win the AFC South
- 2% to win the AFC
- Less than 1% to win the championship
The Colts therefore enter Arrowhead with considerably more pressure on their early-season futures position.
Falling to 0-2 would not eliminate Indianapolis, but it could push the team's playoff and division probabilities lower heading into a Week 3 home game against Houston.
Patrick Mahomes Passing Markets for Sunday Night Football
Kalshi is also offering several Patrick Mahomes performance markets for Sunday night's game.
Current passing-yard probabilities include:
- Mahomes 200+ passing yards: 65%
- Mahomes 225+ passing yards: 49%
- Mahomes 250+ passing yards: 33%
The 200-yard threshold is currently the most heavily favored of those three listed levels.
Kalshi's passing-touchdown market shows:
- Mahomes 1+ passing TD: 84%
- Mahomes 2+ passing TDs: 52%
- Mahomes 3+ passing TDs: 22%
That puts at least one Mahomes touchdown pass among the stronger player-level probabilities attached to the game.
Kansas City Is Favored Despite Lower Season Futures Prices
One interesting part of the current market is the gap between Kansas City's Sunday-night probability and its longer-term futures prices.
The Chiefs are roughly 72% to win this individual game, but only around 6% to win the championship and 12% to win the AFC.
That difference illustrates how prediction markets separate one-game expectations from season-long outcomes.
Kansas City can be a strong favorite against Indianapolis without being the market's dominant championship favorite.
Indianapolis Playoff Chances Sit at 30%
The Colts' broader market position makes Sunday night particularly important.
Indianapolis currently has only a 30% probability of reaching the postseason on Kalshi.
The AFC South remains open early in the season, but Jacksonville entered the weekend at 1-0 and was priced around 43% to win the division.
Indianapolis sits at approximately 16%.
A road upset over Kansas City would likely improve both the Colts' playoff and AFC South prices.
A second straight loss could move those markets in the opposite direction.
How the Kalshi Colts vs Chiefs Market Works
Kalshi's game-winner market allows users to trade contracts tied to the official result.
A Kansas City contract trading around 72 cents represents an implied market probability of approximately 72%.
