Kalshi versus Polymarket for college football does not have a single winner. Across the 12-team national title board, the best posted price splits almost evenly: Kalshi is cheapest on the top favorites (Ohio State, Oregon, Indiana and Miami), while Polymarket holds the better price on most of the rest (Notre Dame, Texas, Georgia, LSU, Alabama and Texas A&M). The better venue is a team-by-team question, not a platform-wide verdict.
Which venue has better CFB title prices?
The market prices Ohio State as the clear favorite at a fair value of 11.4%, with the cheapest contract at 13c on Kalshi. Notre Dame sits right behind at 11.2% fair value, and its best price of 13c comes from Polymarket. Those two lines, level on the model but sourced from different venues, capture the whole story: the price leadership flips depending on which team is in question.
Counting the board, Kalshi carries the best price on more of the heavy favorites, while Polymarket carries more of the total names once the tail is included. That is a structural split, not a rounding artifact. Each venue runs its own order book, and the de-vigged consensus fair value is drawn from Kalshi, Polymarket and ProphetX combined, so no single platform sets the reference number.
Where Kalshi wins the price
Kalshi holds the cheaper number on the front of the board. Oregon prices at 11c against a 10.6% fair value, Indiana at 10c against 8.8%, and Miami at 8c against 7.5%. Ohio State at 13c anchors the group as the shortest contract on offer.
The pattern is that Kalshi tends to lead where liquidity and attention concentrate, which is the cluster of teams the market treats as genuine contenders. For a trader building exposure to the favorites, Kalshi is the first book to check. The FADE code adds a trading bonus on Kalshi, but the posted price is what matters when comparing venues.
Where Polymarket wins the price
Polymarket carries the better price deeper into the board. Texas is 11c against a 10.1% fair value, Georgia 10c against 8.7%, and LSU 6c against 5.4%. Further out, Alabama sits at 3c and Texas A&M at 2c.
Texas A&M is the one contract on this list trading below the model: 2c against a 2.5% fair value, a small gap but the only case where the posted price undercuts the de-vigged number rather than sitting above it. For traders shopping the tail, Polymarket is the more frequent home of the cheapest line, and the TGSWC code applies there.
Why the better price depends on the team
Most best prices still sit above fair value, which is the vig floor at work: Ohio State's 13c against 11.4% and Notre Dame's 13c against 11.2% both carry a premium over the model. That premium is what a buyer pays to hold the contract, and it varies by venue and by team.
The practical read is that there is no shortcut to one platform. Because the cheapest price flips between Kalshi and Polymarket across the board, the only durable edge is checking both books before taking a position. A venue that leads on the favorites can trail on the tail, and the reverse holds just as often.
Prices and the model can both be wrong, and none of this is financial advice. What the data supports is narrow and useful: the better CFB price is a per-team answer, and line-shopping across Kalshi and Polymarket is the mechanism that captures it.
