The Baltimore Ravens open their 2026 NFL season at the Indianapolis Colts on Sunday, September 13, in a spot the market has already sorted: a road favorite priced on quarterback and roster, perched on the most important number in football.
The Quick Answer
The early consensus line makes the Ravens 3.5-point road favorites with a total near 48.5, and the de-vigged sportsbook prices say Baltimore wins this game about 65% of the time. The one thing worth tracking between now and kickoff is whether that -3.5 survives or crosses the key number 3. The live prices, the Kalshi market status, and the full case for why two 8-9 teams are priced this far apart are below.
Game Header: Ravens At Colts, NFL Week 1
| Matchup | Baltimore Ravens at Indianapolis Colts (NFL Week 1) |
| Kickoff | Sunday, September 13, 2026 · 1:00 p.m. ET · CBS |
| Venue | Lucas Oil Stadium, Indianapolis (indoor) |
| Early Consensus Line | Ravens -3.5 · total 48.5 (schedule-release market; context only, subject to move) |
| Live Capture (Aug. 19) | Colts +3.5 at -108 (BetRivers) · Colts moneyline +165 (BetRivers) |
| De-Vigged Read (Aug. 19) | Roughly 65% Baltimore, 35% Indianapolis once the vig comes out |
Strip the juice out of that moneyline and the market is not saying "slight lean, Baltimore." It is calling the Ravens about a two-in-three favorite. Prices in the live-capture row are a dated snapshot, not a standing quote; the number you can actually bet lives on the live NFL odds screen, where you can shop the line across the books it tracks whenever you read this.

Sportsbook Prices Vs. Kalshi, Side By Side
Because this game trades in two different venues, you can price it two ways.
| Market | Sportsbooks (Aug. 19 capture) | Kalshi |
|---|---|---|
| Colts To Win | +165 (BetRivers) · de-vigged ≈ 35% | Listed, no trades yet |
| Ravens To Win | ≈ 65% implied by the same de-vig | Listed, no trades yet |
| Point Spread | Colts +3.5 at -108 (BetRivers) · de-vigged ≈ 49% | The winner market is what Kalshi lists under this event |
One quirk to read correctly: the OS board is single-sided and surfaces one side per market, which is why the captured prices are the Indianapolis ones. The Baltimore side is implied by the same de-vig, the quoted best prices in this capture happen to be BetRivers', and the probabilities come from the board's de-vigged multi-book consensus. There was no total posted for this game on the board in the August 19 capture.
Kalshi's winner market for this game has been open since May 15 and had not printed a single trade as of August 19. The ticker is KXNFLGAME-26SEP13BALIND, one yes/no contract per team, listed under Kalshi's NFL game markets. A quiet book is normal for a regular-season game this far from kickoff: prediction-market liquidity shows up when the public does, in the final days before a game. Until then, the sportsbook consensus is the only real price signal, and it implies contracts near 65 cents on Baltimore and 35 cents on Indianapolis if Kalshi traders end up agreeing with the books. When the first trades print, a gap between the exchange price and the de-vigged book number in either direction is a genuine piece of information.

What The Market Is Saying About Two 8-9 Teams
Both teams finished 2025 at 8-9, and the raw scoring says Indianapolis was the better of the two. The Colts scored 466 points and allowed 412, a +54 differential. Baltimore scored 424 and allowed 398, which comes out to +26. Take the names off those two season lines and the +54 team has no business catching 3.5 points at home from the +26 team.
That inversion is this page's real story. The market is not taking last season's records at face value. A 65/35 price for the road team says the books believe Baltimore's 8-9 was the fluke and Indianapolis's scoring was closer to a mirage. Home teams get a couple of points of home-field advantage in every NFL line, so put this game on a neutral field and Baltimore is being priced as something like a five-to-six-point better team. That is a playoff-team-versus-middling-team gap, hung on two clubs that finished with the same record.
The quarterback rooms are where the books are making that bet. Baltimore returns Lamar Jackson, active with no injury designation on the August 19 roster check, and his floor is the kind of thing a market will happily pay for over a stale 8-9. Indianapolis's roster carries both Daniel Jones and Anthony Richardson Sr., and however that room resolves by September, the market is clearly treating it as a discount rather than a weapon. Our season-long pages price the same disagreement one bet wider: see the Ravens' 2026 win total and the Colts' 2026 win total for how the books frame each team's full season.
One environmental note that sharpens the read: Lucas Oil Stadium has a retractable roof, so weather is a far smaller variable here than at an open-air September kickoff, though it is not zero until the roof call is made. Little about this price is a weather discount. It is close to a pure talent-and-situation number.
What To Watch Between The Capture And Kickoff
The half point is the story. Here is what actually matters between the August 19 capture and the September 13 kickoff, in order.
-
Does -3.5 hold, or does it cross 3? NFL games land on a margin of exactly 3 more often than any other number. A Ravens backer holding -3.5 loses the games Baltimore wins by exactly a field goal; at -3 those become pushes. On a 2023 episode of Eytan's Essentials, breaking down a teaser that moved a spread to minus two and a half, Eytan framed the payoff as being "on the right side of the number one key number." The standing OddsShopper rule on buying that half point: pay to move onto 3 only when it is cheap, in the 10-cent range, because books usually charge well more than that for it and an overpriced half point is a long-term loser. The push-frequency math behind the rule lives in our guide to NFL key numbers.

Kalshi's first prints. This line trades in two venues, and one of them is still empty. The sportsbook number is live now; Kalshi's market has been listed since mid-May without a trade. So the real timing question is not early-versus-late, it is whether you take the book's 65/35 read as it stands or wait for the exchange's opening trades to tell you whether its traders agree. If those first prints come in meaningfully off 65 cents on Baltimore, one of the two venues is wrong, and that disagreement is the cheapest information this game will produce before kickoff.
-
Roster news is the biggest mover of this line before kickoff. Camp injuries, preseason snaps for either quarterback room, and cut-day decisions are the movers. A price captured in mid-August can be stale by Labor Day, which is exactly why every number on this page carries its capture date. Treat the live odds screen as the source of truth and this page as the map for reading it.
The Bottom Line On Ravens Vs Colts
Two 8-9 teams, one clear favorite: the market has taken a side on which of last year's records was real, and it took the side of the team with the worse point differential, half a point above the most contested number in football. Everything between the August capture and the 1:00 p.m. ET kickoff on September 13 is an argument about whether -3.5 deserves to survive. Shop the number before you take a side, and if you want the vig-stripped fair price on every line in this game rather than just the winner market, that is exactly what OS Pro's +EV tools are built for.

FAQ: How These Prices Work

Who is favored to win? Baltimore. The de-vigged sportsbook prices put the Ravens around 65% and the Colts around 35% as of the August 19 capture.
Can I trade this game on Kalshi? Yes: the winner market is KXNFLGAME-26SEP13BALIND, one yes/no contract per team. It has been listed since mid-May but had no trades as of August 19, so there is no exchange price to quote yet. Kalshi is a CFTC-regulated exchange; 18+ and eligible states only.
How do Kalshi prices compare to sportsbook odds? A contract's price in cents is roughly the market's win probability: a 65-cent contract implies about 65% and pays $1 if it hits. Strip the vig from a sportsbook moneyline and the two should sit close together; a persistent gap between venues is worth investigating before you bet either one.
When and where is the game? Sunday, September 13, 2026, 1:00 p.m. ET, Lucas Oil Stadium in Indianapolis, on CBS, in Week 1 of the NFL regular season, played indoors.
All probabilities on this page are de-vigged market estimates, not guarantees, and every price carries its capture date because lines move. Kalshi event contracts trade on a CFTC-regulated exchange; you must be 18 or older and in an eligible state to participate. Bet responsibly.
