Hedging means betting on the opposite outcome of one or more of your parlay legs. Done correctly, it guarantees you profit regardless of the final result — at the cost of reducing your maximum payout. The key is timing: hedge too early and you sacrifice upside. Hedge at the right moment (when you have 1–2 legs left and the payout is large) and you can lock real money.

Formula: Hedge amount = Parlay payout ÷ Decimal odds of opposite side. Guaranteed profit = Payout − Hedge amount − Original stake.

Expected Value (EV) is the single most important concept in sports betting. It answers one question: is this bet mathematically profitable over the long run?

A bet is +EV when the odds you're getting are better than the true probability of the outcome. Sportsbooks build in a margin (called the 'vig' or 'juice') so most bets are actually -EV by default. Capy strips out the vig to find the true probability, then checks whether the best available line across all books beats it.

Example: If the true probability of the Lakers winning is 60%, but FanDuel is offering odds that imply only 55% — you're getting a better price than the market thinks is fair. That's +EV. Bet enough +EV spots and you'll be profitable long term.

The Kelly Criterion takes this further — it tells you exactly how much of your bankroll to risk on each +EV bet to maximize long-term growth without going broke.

True probability vs. Implied probability from odds

+EV (implied < true)

-EV (implied > true)

You're getting better price than market Market is pricing you out

Books price both sides so they profit regardless of outcome. The vig inflates implied probabilities. Removing it reveals the true market price.

Anything above +2% is strong. Even +1% adds up over hundreds of bets. Avoid -EV bets.

Kelly maximizes long-term growth but can suggest large bets on high-confidence edges. Many bettors use Half-Kelly (half the suggested %) to be more conservative.

EV calculations are estimates based on market-implied probabilities. Past performance does not guarantee future results. Bet responsibly.
