Most people think bookmakers try to estimate the true probability of a match and then add a margin.
In practice, their real problem is predicting how people will bet.
A simple coin-flip example shows why:
Even with a 10% overround, if 80% of money lands on one side, the bookmaker becomes exposed to extreme short-term variance.

– how emotional teams distort football markets
– why positive expected value does not prevent bankruptcy
