Answer: EV stands for expected value — the average profit or loss a bet would produce if you placed it many times. A positive-EV (+EV) bet makes money long term; a negative-EV bet loses. It equals your win probability times the profit, minus your loss probability times the stake.

Key takeaways

  • EV is your long-run edge (or loss) per bet.
  • +EV means profitable over time; -EV means not.
  • Reduced juice turns more bets into +EV.

Why this matters

Sharp bettors bet on EV, not gut feel. Short-term results are noisy; EV tells you whether the process wins.

The Bet105 difference

A bet can win and still be -EV (you got lucky), or lose and be +EV (right process, bad luck). Judge your betting by EV, not by individual outcomes.
