Among the longshots on the national-title board, Alabama is the one dark horse whose best available price sits below the model's fair value. Alabama's cheapest contract is 2c on Polymarket against a fair value of 2.5%, a rare discount on a board where nearly every longshot trades at a premium.
That distinction matters. Most longshot prices look cheap in absolute terms yet still sit above their true probability once the vig is stripped out. Alabama is the exception the model flags.
Why most longshots carry a premium, not an edge
A dark-horse edge is not the same as a low price. The model builds a de-vigged consensus fair value from Polymarket and Kalshi, then compares it to the cheapest venue. When the best price still lands above fair value, the contract is priced rich, not cheap, however small the number looks.
That is the norm at the bottom of the board. LSU's best price is 6c against a 5.1% fair value. Miami sits at 8c against 6.8%. Indiana prices 9c against 8.5%. Each carries roughly a point of premium, which is the market charging for the longshot itself.
Texas A&M is closer to fair, with a 3c price against a 2.8% fair value, but the price still sits on the expensive side of the model. The pattern holds: cheap tickets, thin or negative edges.
Where does the model see fair value on the longshots?
The chart below shows the model's fair value for the six longshots in focus. These are probabilities, not prices, and they set the bar every best price is measured against.
Fair value clusters between 2% and 8.5% here, which is the range where a one-cent move in price swings the edge from cheap to rich. That sensitivity is why the premium on LSU, Miami and Indiana reads as a fade rather than a buy.
How do the best prices compare?
Set the best prices beside those fair values and the Alabama case stands alone. Its 2c price is below its 2.5% fair value, the only clean discount in the group. Oklahoma's 2c sits almost exactly on its 2.1% fair value, so it grades as par rather than value.
Everywhere else the price tops the model. Miami at 8c, Indiana at 9c and LSU at 6c each clear their fair value, and Texas A&M at 3c edges just over its 2.8% mark.
Polymarket holds the best price on all four of the deepest longshots, including both the Alabama discount and the Oklahoma par line, which is where a dark-horse trader would look first.
How to read a dark-horse edge
The takeaway is narrow by design. On the current board the only longshot trading under model fair value is Alabama at 2c against 2.5%, with Oklahoma at par and the rest priced over the model. Dark-horse value is not a category here; it is a single contract.
Prices and the model both move, and both can be wrong. A one-cent shift flips these thin edges, so the read is only as current as the 2c line that produces it. This is analysis of market pricing, not financial advice.
