Is a bookmaker wrong about Western Michigan Broncos – Boise State Broncos?
Babeth checks nearly 30 bookmakers against these probabilities every 45 seconds. When one pays more than the fair odds, she tells you where, at what price and how much to stake.
How are these probabilities computed?
Bookmakers build a margin into their odds: the implied probabilities add up to more than 100 %. We start from the sharpest bookmaker on the market — the one whose prices best predict results — and remove that margin (power method) so the probabilities sum to exactly 100 %.
We then blend in the consensus of the other bookmakers, weighted by how many quote the market. The result is a fair probability and a fair odds figure: the price at which a bet neither wins nor loses money in the long run.
It is not a prediction. A 65 % favourite loses more than one time in three. The only way to make money is to be paid more than the real chance justifies — which is exactly what the app looks for.
