Ohio College Football Championship Odds 2027

Ohio State's Loss at USC Drops the Buckeyes Out of the Title Market's Top Tier

Ohio State national championship odds for 2027 have fallen from a four-team tie at the top of the board to the second tier, and the market rests on a plain reading of the 12-team College Football Playoff: a second loss in late October does not end a season, but it turns a team that controlled its route through the Big Ten into one that has to chase. Ohio State plays its home games at Ohio Stadium in Columbus, Ohio, and the championship is decided at Allegiant Stadium in Las Vegas on January 25, 2027. Miami (Ohio) is the only other Ohio program on the board, priced as a long shot. The live board above carries every team's current price.

Ohio State in the National Championship Market

Ohio State is 6-2. ESPN's schedule shows wins over Ball State, Kent State, Illinois, Iowa, Maryland and Indiana, a 24-23 loss at Texas on September 12 and, after its open week, a 30-18 loss at USC on October 31 at the Los Angeles Memorial Coliseum. The win that had shaped the season came on October 17, when the Buckeyes beat Indiana 19-15 in Bloomington. The USC result moved Ohio State from No. 2 to No. 11 in the AP Top 25 and to No. 10 in the AFCA Coaches Poll, both published November 1, 2026, with unbeaten Miami (Fla.) at No. 1 and Georgia at No. 2 in both polls.

The board moved with the result. On October 29, 2026, Kalshi had Ohio State at 13% and Polymarket at 14%, level with Notre Dame and a few points behind Georgia and Miami (Fla.). On November 2, 2026, Kalshi had the Buckeyes at 5% against Polymarket's 7%, which means the market now treats them as about a one-in-twenty champion, an eight-point fall in the cheapest Yes in four days. Georgia had the top price on the board on both venues, 22% on Kalshi against 23% on Polymarket, and Notre Dame sat at 14% on both venues.

What the price is saying is that the loss matters less for whether Ohio State reaches the bracket than for how it would have to win it. A 6-2 team ranked in the top dozen is still in range of one of the seven places the format gives to the highest-ranked teams after the conference champions, but the 2026-27 format also lets the top three seeds, in rank order, select their bowl path, and a team that enters as an at-large seed outside that group has more games to win against better opponents. The Big Ten race is now a chase: ESPN's standings have UCLA at 5-0 in league play and Indiana at 5-1, with Ohio State at 4-1, and the Buckeyes hold the head-to-head result over Indiana from October 17. Ohio State's trading reflects how many people hold a view: about 3.93 million contracts have changed hands on its line on Kalshi and about $60.2K on Polymarket, each venue in its own unit.

Ohio State's Path Through November

The schedule that remains is where the price will move. Ohio State hosts Oregon on November 7 and Northwestern on November 14, plays at Nebraska on November 21 and closes the regular season at home against Michigan on November 28, per ESPN's schedule. None of the four was in the AP Top 25 published November 1, 2026, and Northwestern was No. 23 in the Coaches Poll; Oregon, Michigan and Nebraska are each 5-3.

The conference race matters more than the poll. The College Football Playoff's 2026-27 format gives automatic places to the champions of the ACC, Big Ten, Big 12 and SEC and to the highest-ranked team from six other conferences, and seven more go to the next highest-ranked teams. A Big Ten title would restore the route Ohio State had before October 31; an at-large place keeps it in the bracket without one, and the selection committee's weekly rankings, starting November 3, are the first official word on how it views a two-loss Ohio State.

The board does not share the polls' view of every unbeaten team. UCLA, unbeaten and No. 5 in the AP poll, was at 3% on Kalshi on November 2, 2026, the only venue quoting it, and Utah, unbeaten and No. 3, was also at 3% on Kalshi, again the only venue pricing it. That is a market reading of schedule strength: even after two losses, the board grants Ohio State more title equity than either of two unbeaten teams it has not yet seen tested against a playoff field.

Miami (Ohio) and the Rest of the State

Miami (Ohio) is the second Ohio program on the board, and Kalshi is the only exchange pricing it. Kalshi had the RedHawks at 1% on November 2, 2026, the floor of its board and the same figure it shows for most of the long tail, which means the market treats their title chance as indistinguishable from that of dozens of other programs. The RedHawks are 5-3 and 3-1 in the Mid-American Conference, behind Ohio University, which leads the league at 4-0 in ESPN's standings, and Western Michigan at 4-1. Their losses came at Pittsburgh, at Cincinnati and at home to Bowling Green.

The route the format offers a team in Miami (Ohio)'s position is narrow. The CFP's 2026-27 rules give one place to the highest-ranked team from the American, Conference USA, the Mid-American, the Mountain West, the Pac-12 and the Sun Belt, so a MAC team needs to finish ahead of every team in those six conferences in the final rankings on December 6 before it gets a playoff game at all. The RedHawks were unranked in both polls published November 1. Their next games are at home at Yager Stadium in Oxford: Buffalo on the evening of Tuesday, November 3, and Ohio University on November 10, before trips to Kent State on November 17 and Western Michigan on November 24.

The Case Against the Ohio State Title Read

The strongest case against the price is that the market has over-corrected for one road loss. Ohio State's two losses came away from Columbus, at Texas, now No. 10 in the AP poll, and at USC, now No. 18, by a combined 13 points, and it has already won at Indiana, the Big Ten team directly ahead of it in the standings. A holder of this view would add that the 12-team bracket was built for exactly this kind of team, that a two-loss Ohio State that wins its last four would be hard to leave out, and that once in the bracket the Buckeyes would be priced alongside the teams the board now ranks well ahead of them. On that reading, Kalshi's 5% on November 2, 2026 understates a team that still controls most of its own November.

The answer the price gives is that a team without a conference title and outside the top three seeds has more playoff games to win, each against a team good enough to be there, and the board prices every one of them. It has not written Ohio State off: its best price still sits above those of two unbeaten teams, Utah and UCLA. It has moved the Buckeyes from the top of the board to the group behind it.

What Changes the Ohio State Title Read

This read would be wrong if November gives Ohio State back the route it lost at USC, or takes away the at-large one, and the price will move on dated, public events between now and January:

• First CFP rankings: the selection committee releases the first of its six rankings on Tuesday, November 3, 2026, on ESPN, and weekly after that through December 1; where Ohio State sits relative to the top 12 is the first official read on its at-large standing.

• The Oregon game: Oregon visits Ohio Stadium on November 7; a third loss would put a playoff place itself in question, and a win keeps the Buckeyes in the Big Ten chase.

• The Big Ten race: UCLA at 5-0 and Indiana at 5-1 lead Ohio State at 4-1 in league play, so a loss by either in November reopens the conference route.

• The Michigan game: the November 28 regular-season finale at Ohio Stadium settles Ohio State's place in the Big Ten race.

• Selection Day: the final rankings and the 12-team bracket, with game sites, are announced Sunday, December 6, 2026.

• The title game: the CFP National Championship is played Monday, January 25, 2027, at Allegiant Stadium in Las Vegas.

When the College Football Championship Market Resolves

Kalshi lists the board as College Football National Championship Winner 2026-27 (event KXNCAAF-27). Its Ohio State contract resolves Yes if Ohio State wins the College Football Playoff National Championship Game, and the same rule applies team by team, including a separate Miami (Ohio) contract; Kalshi gives an expected expiration just after the game, at 11 p.m. Eastern on January 25, 2027. Polymarket's market resolves Yes for the listed team determined as the national champion of the 2026-27 College Football Playoff, resolves a team No as soon as it can no longer be named champion, uses official NCAA information with a consensus of credible reporting as a backstop, and resolves to "Other" if the title game is cancelled or postponed past February 8, 2027 or no champion is declared by then.

Polymarket lists Ohio State but has no contract for Miami (Ohio), which is why that program carries a single venue. For both venues the date that matters is January 25, 2027; no ranking, conference title or Selection Day announcement settles anything on its own.
