Prediction-market prices move for three reasons: liquidity (how much size the order book can absorb), news (any information that changes a team's outlook), and the pull of the model's fair value (the anchor the price drifts toward or away from). Every tick on the CFB title board is one of those three forces at work, and usually a mix of all three.
How does liquidity move prediction-market prices?
Liquidity is the depth of the order book: how many contracts sit on the bid and the ask. When a book is deep, a large order barely nudges the price. When it is thin, the same order sweeps several levels and the print jumps.
This is why longshots move more violently than favorites. A contract like Oklahoma at 2% fair value trades on a thinner book than Ohio State at 11.3%, so a single motivated buyer can lift the price a full cent or two without much capital. Favorites near the top of the board absorb size and hold their level.
Summer is the thinnest part of the CFB calendar. Fewer traders are active, books are lighter, and prices are more sensitive to any one order. The model treats a single thin quote with suspicion and leans on the de-vigged consensus across venues instead.
How does news reprice a contract?
News is anything that changes a team's real outlook: a depth-chart shift, a transfer, a preseason ranking, or a change in strength of schedule. When information arrives, informed traders move first, and the price adjusts before slower participants react.
The size of the move scales with surprise. Confirmation of an expected starter barely registers; an unexpected development can reprice a contract several cents in minutes. Notre Dame and Ohio State both sit at 11.3% fair value, and a genuine shift in either program's outlook is what separates them on the board.
The key is distinguishing signal from noise. A price that jumps on real information should stick; a price that jumps on a single thin order tends to revert. The model reads persistence as the tell.
Why is the model's fair value the anchor?
The model builds fair value from power ratings and schedule, then strips the vig out of live prices across Kalshi and Polymarket to form one consensus number. That number is the reference point every contract is measured against.
When price sits above fair value, the contract is priced rich and reads as a fade. When price sits below, it reads as value. Ohio State and Notre Dame both carry an 11.3% fair value against a 13c best price, so the market is charging a modest premium to the model's read at the very top of the board.
Prices and models can both be wrong, and fair value is an estimate, not a verdict. The edge is not in any single quote but in tracking how far, and for how long, price drifts from the anchor.
Where do the cheapest prices sit right now?
Because each venue runs its own book, the cheapest price for a team is not always on the same exchange. The model surfaces the best venue per team so traders pay the lowest entry for the same contract.
Texas trades cheapest at 11c on Polymarket, while Georgia is cheapest at 10c on Kalshi. Oregon sits at 11c on Kalshi and Miami at 8c on Polymarket. The spread between venues is small at the top but meaningful on longshots, where a cent is a larger share of the price.
New traders comparing venues can note the standing promos: Polymarket TGSWC (deposit $20, get a $50 trading bonus) and Kalshi FADE (trade $25, get up to $500). The venue with the cheapest quote, not the biggest promo, is what the model optimizes for.
Putting the three forces together
Liquidity sets how far a price can travel on a given order, news supplies the reason to travel, and fair value defines whether the destination is rich or cheap. A durable move usually shows all three: real information, enough flow to reprice, and a new level that holds against the model's anchor.
For CFB futures, the practical read is to weight persistence over any single tick, treat thin-book jumps with caution, and measure every price against the de-vigged consensus rather than a lone venue quote. That is how price discovery actually works on the title board.
