A college football futures price reads as a probability almost on sight: a contract quoted at 12c is the market pricing roughly a 12% chance that outcome hits. That single conversion, cents to percent, is the whole starting point for reading these markets.
The catch is that raw prices run a little hot. The spread built into every quote pushes it above the true odds, so the number worth trading on is the de-vigged fair value, not the sticker price. Notre Dame sits at a 12c best price but an 11.1% fair value, a compact example of the gap.
Does a 12c contract mean a 12% chance?
Close enough to use, with one adjustment. A contract that settles at 100c if it wins and 0c if it loses behaves like a probability, so its price in cents is the market's implied chance. At the top of the national title board, Notre Dame, Miami and Ohio State all carry a 12c best price, which reads as roughly a 12% implied chance each.
That first read is directional, not final. The raw price overstates the odds by the size of the spread, which is why three teams can all show 12c yet carry different de-vigged fair values underneath. The cents tell the story; the fair value corrects the accent.
Why raw futures prices overstate the odds
Every quoted price includes a margin. Market makers and the spread between bids and offers mean a contract trades slightly above the probability it truly represents, so summing the raw prices across a full field lands above 100%. That surplus is the overround, and it is the market's built-in cushion.
Reading prices as probabilities without accounting for that cushion inflates every team at once. The fix is de-vigging: rescale the raw prices so the field sums back toward a coherent 100% and each team's number reflects its share of the probability, not its share of the price plus margin.
How de-vigging turns price into fair value
De-vigging is the step that converts a tradable price into a probability worth citing. Notre Dame's 12c best price becomes an 11.1% fair value; Miami's 12c becomes 10.2%; Ohio State's 12c becomes 10%. Same headline price, different underlying probability once the spread is removed.
The consensus fair value blends venues, so it smooths single-market noise. Texas and Oregon both land at 9.8% fair value off 11c best prices, and Indiana reads 8.9% off 11c. The pattern is consistent: the raw cents sit a notch above the model's read of the real chance.
The gap between price and fair value is the number that matters. When the cheapest available price sits above fair value, the contract is rich; when it sits below, there is model-flagged value to capture.
Where the cheapest price beats fair value
Once fair value is set, the second read is venue. The same team can trade at different cents across exchanges, and the lowest entry price changes the math on any position. Ohio State's cheapest contract is 12c on Polymarket, while Notre Dame, Miami, Texas and Oregon show their best prices on Kalshi.
Lining raw price against fair value across venues is the core screen. Notre Dame at 12c versus 11.1% fair value, and Miami at 12c versus 10.2%, both show price sitting above the model's number, the profile of a fade rather than a buy.
For traders comparing venues, promotions can offset entry cost: Kalshi's FADE (trade $25, get up to $500) and Polymarket's TGSWC (deposit $20, get a $50 trading bonus) are the two venues quoting these title contracts. Prices and the model can both be wrong, so the framework is a lens, not a guarantee.
