Prediction-market prices move for three reasons: liquidity, news and the model's fair value. Liquidity sets how easily price can be pushed, news changes the underlying probability, and the model's fair value is the anchor that says where a contract should trade once the vig is removed. Read together, they explain why an 11c contract can still map to an 8.5% chance.
How does liquidity move a price?
Liquidity is the depth of resting orders. In a deep book, a large order gets absorbed with little price change; in a thin one, the same order walks the price several cents. College football futures are seasonal and thin in July, so quoted prices carry a wider band around fair value than a deep, in-season market would.
This is why the raw price and the model's fair value diverge. On the 2026 title board, Texas, Oregon, Notre Dame and Miami all show a best price of 11c on Kalshi against a fair value of 8.5%. That roughly 2.5 cent wedge is the market maker's cushion plus the cost of thin depth, not free edge.
Thin books also mean price can drift without news. A single motivated buyer lifting the offer moves the last-traded print, and screen-watchers read that as signal when it is really just flow.
How does news change fair value?
News is the input that should move probability, and therefore fair value. A depth-chart change, a transfer, a result once the season starts: each feeds the power ratings the model converts into win probabilities. When those probabilities shift, the model's fair value shifts with them.
The distinction that matters for traders is timing. Price often reacts to news first, in seconds, while the model re-rates only when the estimate genuinely changes. That lag between a jumpy price and a stable fair value is the window where mispricing is visible.
The current board shows the model clustering comparable teams. Ohio State and Indiana both sit at a 6.9% fair value and a 9c best price. Georgia sits a tier below at 5.2% and 7c. Those steps are the model's read on separation, not the market's mood.
What the model's fair value actually anchors
The model's fair value is the de-vigged consensus: it removes the built-in overround so the numbers behave like probabilities. Sum the raw prices across a crowded field and the total runs well above 100%; the fair value figures are what remain after that vig is stripped.
So the model's view is not a price prediction, it is a reference point. When price sits above fair value, as it does across the top of the 2026 board, the excess is the trading cost. When price sits below fair value, the model flags potential value, subject to the same liquidity caveats.
Reading the current title board
The top tier is tightly packed. Four teams share the same 8.5% fair value and 11c price, which tells traders the model sees no meaningful separation among Texas, Oregon, Notre Dame and Miami this early. Differentiation there will come from news, not from the current market.
Below them the ladder is orderly: Ohio State and Indiana at 6.9%, Georgia at 5.2%, LSU at 4.4%. Cross-venue shopping across Kalshi, Polymarket and ProphetX is how the cheapest entry per team gets found once more venues quote these contracts; promo access such as Kalshi FADE or ProphetX VAULT only matters after the price itself is the best available.
None of this is advice, and the model can be wrong. Prices move because liquidity, news and fair value rarely agree at the same instant, and the disagreement is the whole game.
