Prediction-market prices move on three distinct forces: liquidity in the order book, incoming news, and the model's fair value acting as a gravitational anchor. Reading a price move well means identifying which of the three is driving it, because a swing from thin liquidity carries no information while a swing from news or a fair-value gap does.
What are the three forces behind every price move?
Liquidity is the depth of resting orders. When a book is thin, a single trader taking size can lift a contract several ticks without any change in the underlying picture. When a book is deep, the same order barely registers. This is why move size alone says little until the book depth is known.
News is the information layer: results, injuries, suspensions and schedule developments that change a team's path. Genuine news tends to move price in the same direction across all three venues at once, which distinguishes it from a one-venue liquidity blip.
The model's fair value is the anchor. The de-vigged consensus estimates a true probability for each team, and persistent gaps between best price and fair value tend to close over time. When price drifts from the model without news, that gap is the signal worth watching.
How does liquidity shape CFB title prices right now?
The current national title board shows the liquidity effect cleanly. At the top, Georgia carries a 14.4% fair value with a best price of 16c on Polymarket, and Texas and Ohio State sit at 13c each on Kalshi. These favorites trade on deeper books, so flow is absorbed and prices move in small, orderly increments.
At the tail, Texas Tech prices at 1c against a 1.5% fair value. A contract that cheap moves on the lightest order flow, so a one-tick swing there is mechanical, not informational. The same applies to Ole Miss at 3c and Alabama at 3c: small notional moves register as large percentage changes.
The practical read: a two-tick move on Georgia means something different from a two-tick move on Texas Tech. Context from book depth has to come before any conclusion about news.
When does a price gap signal the model's view?
A standing gap between best price and fair value is where the model's view shows up. Georgia's 16c best price against a 14.4% fair value puts the market a shade above the model, a small premium rather than a mispricing. Notre Dame tells a similar story at 13c versus 11.9%.
Lower on the board, LSU prices at 5c on Polymarket against a 5.5% fair value, meaning the cheapest venue sits slightly under the model's estimate. Gaps like that, when they persist without news, are the cleanest expression of the model disagreeing with the market.
The discipline is separating a gap that reflects a genuine model edge from one that reflects stale pricing on a thin book. The former holds across venues; the latter tends to vanish as soon as size arrives.
How to read the next move
The sequence is liquidity first, news second, model third. Check whether the book is deep or thin, then whether the move appeared across venues or just one, then whether price has drifted from fair value without a cause. That order filters most noise before any trade thesis forms.
Venue still matters for execution. The board shows the cheapest price split across platforms: Polymarket holds the best Georgia, Notre Dame, LSU and Oregon prices, while Kalshi owns Texas, Ohio State, Miami, Indiana and Florida. Where fair value and price diverge, the venue with the better number is the one worth routing to. New accounts can explore the venues with Kalshi code FADE or Polymarket code TGSWC.
Prices and the model can both be wrong, and none of this is financial advice. The point is narrower: every move has a cause, and naming the force behind it is the first step in reading the board.
