The model gives Indiana a 49% win probability at home against Ohio State on Saturday, October 17 (week 7), which leaves Ohio State at 51%. That is a coin flip, and it stands in sharp contrast to the season-long futures market, where Ohio State prices as a top-tier title contender and Indiana prices as a second-tier longshot.
The split matters: a single-game market and a national-title market answer different questions. The title board asks who wins it all in January. The game market asks who wins one Saturday in Bloomington. The model reads those two questions very differently for this matchup.
How do the markets price Ohio State vs Indiana?
On the national-title board, Ohio State's fair value is 15.4%, best priced at 17c on Kalshi. Indiana's fair value is 6.6%, best priced at 7c on Kalshi. That is roughly a two-to-one gap in title equity between the two programs.
That gap is the season narrative, not the game read. A team can be a far stronger title bet over a full season while still facing a near-even single game, particularly on the road against a quality host. The model's 49% for Indiana is a statement about this one game, where home field compresses the margin the title board implies.
Kalshi owns the best listed price on both contracts here, which is worth noting for anyone comparing venues before the game market settles into tighter two-way quotes.
Why does the model give Indiana 49%?
The model builds each game from power ratings and then adjusts for site. Indiana hosting pulls the number toward even, and the output lands at 49% for the Hoosiers, 51% for the Buckeyes. In probability terms this is the closest kind of game the model prices: neither side clears 52%.
The practical read is that the title-market gap overstates the one-game edge. Ohio State is the stronger program by the futures board, but the model does not translate that season-long standing into a comfortable road favorite. The one-game line is close to a toss-up.
National-title context: where these teams sit
The chart below frames both teams against the rest of the title board. Ohio State sits in the lead group behind Georgia; Indiana sits in the second tier alongside Texas and Alabama. That context explains why a 49% single-game read for Indiana looks aggressive relative to futures, and why the game market is the cleaner place to express a view on Saturday specifically.
Where is the best price, Kalshi or Polymarket?
For the title contracts, Kalshi holds the best listed price on both teams: Ohio State at 17c and Indiana at 7c. The chart below lines those cents up against the rest of the top of the board, so the relative cost of each contract is clear before any game market is priced.
For the game itself, both Kalshi and Polymarket are listing venues. Traders comparing the two should price the model's 49% Indiana read against whatever two-way quote appears and take the cheaper side of fair. Kalshi's new-account code FADE (trade $25, get up to $500) is one route in for anyone starting there.
Prices and the model can both be wrong, and a coin-flip read means variance dominates a single result. None of this is financial advice; it is a read on where the model and the market disagree.
