Monday Night Football odds for tonight, Broncos at Chiefs: between 12 a.m. ET Sunday and 8:24 a.m. ET Monday, Kalshi traders swapped 1,547,874 "Denver wins" contracts and 780,916 "Kansas City wins" contracts, and Denver's price never left 43¢ to 45¢. That 32-hour run is 78% of every Denver contract the market has ever traded, and it changed nothing. The Chiefs are still a 55¢ to 56¢ favorite at Arrowhead, right where they sat on September 2.
Nine AI models priced the same game this morning without seeing any market number. Five took Kansas City, three leaned Denver and one called it even. Where all nine agree with each other and not with the market is the shape of the game: closer and lower-scoring than Kalshi's price says.
Kalshi prices and every trade from Kalshi's public API, pulled 8:24 a.m. ET, Monday, September 14, 2026. Sportsbook lines from the OddsShopper odds feed at 8:28 a.m. ET and DraftKings via ESPN. The AI panel ran 8:27 to 8:32 a.m. ET.
Tonight's Board: Broncos At Chiefs
Kickoff is 8:15 p.m. ET at Arrowhead on ESPN and ABC. Each Kalshi contract pays $1 if its outcome happens, so a price in cents reads as a percent chance. The rows are the winner, each team winning by three or more, and 44 or more total points (the over on 43.5); the table below sets that price beside the sportsbooks and the panel's middle answer.
| Tonight | Kalshi (bid / ask) | Sportsbooks | AI panel |
|---|---|---|---|
| Chiefs | 55¢ / 56¢ | -130 DraftKings, -134 FanDuel | 52% |
| Broncos | 44¢ / 45¢ | +110 DraftKings, +114 FanDuel | 48% |
| KC by 3+ | 49¢ / 50¢ | Chiefs -2.5 at DraftKings | 41% |
| DEN by 3+ | 40¢ / 41¢ | No matching line posted | 40% |
| 44+ points | 48¢ / 49¢ | Total 43.5 at DraftKings | 42% |
Read the Broncos row. A 45¢ Denver contract turns $100 into about $222 back if Denver wins, before Kalshi's trading fee, which runs about 2¢ a contract at that price. FanDuel's +114 returns $214 on the same $100 and DraftKings' +110 returns $210. The best Denver price at a regular app on the feed this morning was +115 (Bet365, Fanatics, Hard Rock), so the exchange and the books sit within a few dollars of each other. The Chiefs side runs the other way: Kalshi's 56¢ ask with the fee lands near -137, a shade worse than DraftKings' -130.
The panel number is the middle answer of nine models after a revision round. These are model estimates, not predictions of fact and not financial advice.

Where The Market Moved: Nowhere, Twice
Denver's contract has traded between 41¢ and 46¢ every day since August 1. For most of that stretch it was a quiet market: on Saturday, September 12, 76,635 Denver contracts changed hands all day. Then Sunday night arrived.
- 7:51:29 p.m. ET Sunday. Two fills in the same second bought 87,440 Denver contracts at 45¢, about $39,350, half an hour before the Cowboys and Giants kicked off Sunday night. The price held its 43¢-to-45¢ range.
- The 11 p.m. hour. 344,336 Denver contracts traded, the busiest hour the market has had. The price stayed between 43¢ and 45¢.
- 11:31 p.m. The largest Chiefs trade on Sunday was a sale: 39,173 contracts sold at 56¢ in one second. The Chiefs' price stayed between 55¢ and 57¢ all day.
- Overnight into Monday. Another 605,232 Denver contracts traded between midnight and 8:24 a.m., 98% of them buys, every one of them at 44¢ or 45¢.
Open interest tells you how many contracts are still held rather than flipped. On Denver it went from about 397,000 at the start of Sunday to 1,847,409 this morning.

How does that much buying fail to move a price? Look at the two asks together: 45¢ for Denver plus 56¢ for Kansas City is 101¢. Anyone willing to sell both sides at those prices collects a penny on every matched pair, and since the start of Sunday both sides have been bought at once: 96% of the Denver volume and 86% of the Chiefs volume were buyers taking the offer. Two-way buying explains part of it. It does not explain all of it, because Denver took about twice as many contracts as Kansas City, so someone was also content to keep selling Denver at 45¢ in size and refilling the offer without raising it. That is the shape of the trade log since Sunday evening.
The side lines barely moved either. "Chiefs by 3 or more" was 50¢ bid, 51¢ ask at noon on September 3 and is 49¢ / 50¢ now, a one-cent drift toward Denver in 11 days. "44 or more points" was 47¢ / 50¢ on September 2 and is 48¢ / 49¢. The books agree with the exchange: DraftKings has the Chiefs -2.5 with a 43.5 total.
What Nine Blind AI Models Said
Each model got the same fact card this morning with no market prices and no sportsbook lines: both teams' 2025 scoring ledgers, every meeting since 2018, Kansas City's home record since 2021, league base rates, both rosters, the live injury feed and the September 12 final injury report. Each stated one view of the margin and the total and derived four numbers from it, then read the other eight anonymously and could revise once. Here is where all nine finished.
| Model | Chiefs win | Chiefs by 3+ | Broncos by 3+ | 44+ points |
|---|---|---|---|---|
| DeepSeek | 57% | 45% | 34% | 41% |
| Claude Opus | 54% | 47% | 40% | 43% |
| GPT | 54% | 44% | 37% | 42% |
| Kimi | 54% | 49% | 39% | 46% |
| Claude Sonnet | 52% | 41% | 39% | 44% |
| GLM | 50% | 39% | 43% | 45% |
| Grok | 47% | 36% | 44% | 41% |

Two lines have all nine models on the same side of the market, and they tell one story. On "Chiefs by 3 or more," every model is below the 49.5¢ midpoint, and the middle answer is 41%. On 44 or more points, every model is at 46% or lower against 48.5¢. On who wins, the panel is close to a coin flip, and for stated reasons rather than a shrug: the seats below 50 all priced Denver's pass rush against a rookie left tackle, and the seats above 50 leaned on Arrowhead, a healthy Mahomes and how close Kansas City's 6-11 season really was. On the winner and on Denver by three, the middle answer lands within four points of the price. Put together, the panel sees a closer, lower-scoring game than the market does. Every number in this piece gets graded in public once the game settles, on the full graded scoreboard. A model that disagrees with a liquid market loses that argument more often than it wins, so treat the gaps as a question for tonight, not an answer.
Where The Panel Changed Its Mind
The case for Denver in the room came down to one matchup. Denver recorded 68 sacks in 2025 and Kansas City 35 (Denver is without linebacker Jonathon Cooper, who is on the Commissioner's Exempt List), and tonight the Chiefs start rookie Kahlil Benson at left tackle with Josh Simmons ruled out, in front of Patrick Mahomes' first game since tearing the ACL and LCL in his left knee on December 14. The case for Kansas City was the scoreboard underneath the records: the Chiefs went 1-9 last year in games decided by eight points or fewer, and in the 13 games before Mahomes got hurt they outscored teams by 4.8 points a game.
GLM opened as the panel's strongest Denver vote and moved the furthest:
Moved KC win from 42 to 50 … I had over-discounted KC's home-field ledger (32-11 since 2021, +6.6 margin) and under-weighted the significance of Mahomes carrying NO game designation after being a full participant all week. — GLM
Claude Opus held its winner number and moved the total instead, and its reason is the best argument on the page for the under:
What moved me was a group of games I had not weighted: the recent meetings where Mahomes played and Kansas City was not resting starters. Those totals were 27, 33, 30 and 41, all under 43.5. — Claude Opus
Claude Fable gave back half of its Denver lean and kept the rest:
I hold the Denver-side lean and hold the over at 42 — the KC-majority case rests on cashing the +6.6 home margin and a fully-normal Mahomes, and neither is warranted tonight. — Claude Fable
The panel's number on this game has walked toward the market all summer while the market sat still. Here is every stored run on the Chiefs winning, the middle answer after each revision round beside Kalshi's midpoint at the moment the panel ran:
| Panel ran | Chiefs win, panel | Chiefs win, Kalshi |
|---|---|---|
| August 12 | 45.5% | 56¢ |
| August 31 | 47% | 56¢ |
| September 2 | 50.8% | 55.5¢ |
| September 9 | 48% | 56¢ |
| September 12 | 52% | 56¢ |
| September 14 | 52% | 55.5¢ |
Mahomes was listed Questionable on ESPN's injury feed on August 12 and September 2, and he carried no designation on the September 12 final report. The market's price in August was already almost exactly where it is tonight; the panel moved from 45.5% to 52% over the same stretch, with a dip on September 9.
What Would Change The Number Before Kickoff
- Inactives, about 6:45 p.m. ET. Chris Jones sat out Saturday's practice in what Andy Reid called a precaution and carries no designation. If he is inactive, the Chiefs side should soften; if he is active, nothing changes.
- Kansas City's first series. The whole Denver case is Benson against that pass rush. Early pressure on Mahomes is the kind of signal that can push the live Denver price up; a clean opening drive can push it down.
- Mahomes' first hit. Every model priced some discount for a first game back from a knee reconstruction. The first time he takes a sack and gets up, watch whether that discount comes out of the live price.
- Late money. A market that absorbed 2.3 million contracts since the start of Sunday without moving has depth. A move of three cents or more before kickoff would likely mean offers got pulled or swept, and it is worth checking which side.

My Take
The thing I keep coming back to is the 11 p.m. hour. More than a third of a million Denver contracts traded in 60 minutes and the price stayed inside two cents. That is not a crowd pushing a number around; that is a crowd running into a wall of offers that does not care. When a line holds through that, I trust the line, and 55¢ to 56¢ on the Chiefs is as settled as a Week 1 price gets.
Where I am curious is the shape of the game. Nine models from seven labs, reading the same card blind, all put Kansas City by three or more at or below the market and all put 44 or more points below it too. Opus found the reason in the series itself, in the four recent meetings quoted above. Since early September the Chiefs-by-three line has drifted about a cent toward Denver and the total has not moved at all. I am not treating that as a bet. I am treating a close, low-scoring game as the one question on this board worth watching at halftime, and it goes into the record either way on Tuesday morning.
