The Longshot Trap
This bet is extremely profitable on paper. Half the bettors are still about to go broke.
For every $1 staked, the mathematical expectation is about +$1.01 profit.
This is an intentionally extreme training example, not a typical sportsbook opportunity.
1% sounds small. Is it small enough?
Let’s give the same bet to 1,000 bettors.
EV answers one question.
Is the price good?
Staking answers another.
How much of your bankroll can survive the way this bet wins and loses?
A huge edge on a rare event can still require a very small stake.
Being right is useless if you run out of money before right gets paid.
Every bettor in this training simulation was taking the same genuinely +EV price. In real betting, true probability is estimated, not known. Here we hold it fixed so we can study staking on its own. Simulation results, not predictions.
