Expected Value (EV)
What you'd win on average if you made the same bet over and over. Like a coin flip where you pay $1 to win $2 on heads—the expected value is $0 (break-even). Positive EV bets profit over time.
Like calculating your average score if you rolled a dice 1000 times. You'd expect around 3.5 per roll.
Why it matters
EV is the only number that matters for long-term profit. Positive EV bets win over time, even if individual bets lose.
How DMP uses this
We calculate EV for every prop to show you which bets have mathematical edge.
Common mistake
Confusing EV with result. A +EV bet can still lose. That doesn't make it a bad bet.
