Ohio State at Iowa on Saturday, October 3 (Week 5) reads as a clear but not lopsided road favorite spot: the model's fair value gives Iowa a 24% win probability, which places Ohio State near 76%. That is the number to anchor every price against this weekend.
What does a 24% Iowa win probability mean in cents?
Prediction-market contracts settle at 100c if the outcome hits and 0c if it does not, so a probability converts directly to a fair price. A 24% Iowa win probability maps to roughly 24c per Iowa contract and about 76c per Ohio State contract before any venue margin is added.
That framing sets the discipline. If Iowa trades above 24c, the price is charging more than the model's read; if Ohio State can be found below 76c, the road side carries positive expected value against fair. Venue vig widens both quotes, so the cheaper effective price is the one worth locating.
The 24% is a game-level model output, not a lock or a fade. It says Iowa is live at home without being favored, which is exactly the kind of range where price shopping across venues matters most.
How does the Iowa game affect Ohio State's title price?
Ohio State's national title fair value sits at 12.6%, with the cheapest contract at 13c on Kalshi. A single road result rarely swings a season-long futures price far, but a stumble in a 76% spot would compress that title number, while a routine win leaves it broadly where it stands.
On the current board, Ohio State's 12.6% trails only Georgia at 13.9% and sits level with Texas, also at 12.6%. The title market treats the Buckeyes as a co-favorite, so Week 5 is less about repricing the season and more about whether the road number holds.
For traders, the game contract and the title contract are separate instruments. The 24% Iowa read informs the Saturday market; the 12.6% fair value governs the futures position.
Where Ohio State sits on the title board
The title board is top-heavy. Georgia leads at 13.9% fair value, then Ohio State and Texas at 12.6%, Notre Dame at 12%, and Miami at 10.6%. Ohio State's placement as a co-favorite is the backdrop to any Week 5 trade.
The chart below shows where the model's fair value places the top of the board. These are season-long probabilities, distinct from the 24% single-game read on Iowa.
How to trade Ohio State on Kalshi or Polymarket
For the title contract, Ohio State is cheapest at 13c on Kalshi against a 12.6% fair value, a slim premium over the model. Texas and Notre Dame both price best on Polymarket, so the cheapest venue varies by team and is worth checking before entering.
New Kalshi accounts can use promo code FADE, which offers up to $500 after $25 of trading. For the Saturday game market, apply the same rule the model implies: pay no more than about 24c on Iowa or about 76c on Ohio State, then let the cheaper effective quote decide the venue.
The chart below compares the best available title price in cents across the top contenders. Prices and the model can both be wrong, and none of this is financial advice; the value is in measuring price against a consistent fair-value anchor.
