Neither venue wins outright. As of September 11, 2026, Polymarket posts the cheapest price on seven of the twelve national-title contracts the desk tracks, while Kalshi holds the other five, clustered at the top of the board. The shortest team on the board, Notre Dame at 12c, prices best on Kalshi. The better venue is a function of tier, not brand.
Which venue has the better CFB title prices?
Counting cheapest-venue wins across the title board splits close to evenly, with an edge to Polymarket on volume. Polymarket carries the low price on Ohio State, Indiana, Texas, LSU, Oklahoma and Texas A&M, plus one deep tail contract, seven in all. Kalshi carries the low on Notre Dame, Miami, Oregon, Georgia and USC.
The pattern is clean: Kalshi owns the top of the board and the near-favorites, while Polymarket owns the middle and the longshots. A trader pricing the chalk and a trader pricing the tail are effectively shopping at different venues.
Price alone is only half the read. The model's de-vigged fair value sets the bar each price is measured against, and the cheapest venue does not always clear below that bar.
Where Kalshi wins: the top of the board
Kalshi's five cheapest-venue teams sit near the front. Notre Dame prices at 12c against an 11.1% fair value, a 0.9 point premium at the top of the market. Miami is 11c on a 10% fair value, and Georgia is 9c on 7.9%.
Oregon is the standout line on the entire board: its 10c best price on Kalshi sits exactly at the model's 10% fair value, leaving no premium at all. USC rounds out the group at 3c against a 2.8% fair value, the only sub-5c contract Kalshi prices cheapest.
Where Polymarket wins: the middle and the tail
Polymarket's book runs deeper down the board. Ohio State prices best there at 12c, though that sits 1.7 points above its 10.3% fair value, the richest premium among the favorites. Indiana is 11c on a 9% fair value, and Texas is 10c on 8.4%.
The venue's real edge shows in the tail. LSU prices at 8c against 7.3%, and both Oklahoma and Texas A&M clear at 2c. Oklahoma is the notable one: its 2c best price sits below the model's 2.2% fair value, the only title contract on the board trading under its de-vigged mark.
For traders who live in the longshot tier, Polymarket is where the cheapest cents concentrate.
Reading across the two books, the split is structural rather than incidental.
Why the same team costs different cents at each venue
Kalshi and Polymarket run independent order books with different liquidity, fee structures and trader bases, so an identical contract can clear at different prices at the same moment. Notre Dame at 12c on Kalshi and Ohio State at 12c on Polymarket carry the same headline price but very different premiums over fair value, 0.9 points versus 1.7.
The model corrects for this by stripping the vig from raw prices, building a consensus fair value across venues, and surfacing the cheaper book per team. That is why the answer to which venue is better is per contract, not global.
The read: shop by tier
The practical takeaway is to route by board position. For favorites and near-favorites, Kalshi holds the low price more often, and it owns the two contracts nearest fair value in Oregon and USC. For the middle and the tail, Polymarket holds the cheaper cents, including the board's only under-fair contract in Oklahoma.
Kalshi lists code FADE and Polymarket lists code TGSWC for new accounts, with terms set by each venue. Prices and the model can both be wrong, and none of this is financial advice; the point is that the cheaper venue is a per-team question, and the current board answers it by tier.
