Fundamentals

1. Understanding Betting Odds

In the U.S., sportsbooks use Odds, which are displayed as either a positive (+) or negative (−) number.

  • Positive Odds (+): Show how much profit you'd make on a $100 bet. Example:

    • +200 → A $100 bet wins $200 (total payout = $300).

  • Negative Odds (−): Show how much you need to bet to win $100. Example:

    • -150 → You must bet $150 to win $100 (total payout = $250).

Key Points:

  • Negative odds = favorite (more likely to win, smaller payout).

  • Positive odds = underdog (less likely to win, bigger payout).


2. Types of Sports Bets

📌 Moneyline

  • Bet on who wins the game.

  • Example:

    • Chiefs -130 → Must bet $130 to win $100.

    • Raiders +110 → Bet $100 to win $110.


📌 Point Spread

  • Bet on the margin of victory.

  • The favorite must win by more than the spread; the underdog can lose by less (or win outright) and still cover.

  • Example:

    • Cowboys -6.5 → Must win by 7 or more points.

    • Giants +6.5 → Can lose by 6 or fewer points (or win outright).

Odds on spreads are usually around -110 on both sides (bet $110 to win $100).


📌 Over/Under (Totals)

  • Bet whether the combined score will be over or under a set number.

  • Example:

    • Over 45.5 → Total combined points must be 46 or more.

    • Under 45.5 → Total combined points must be 45 or fewer.

Odds are often close to -110 for both Over and Under bets.


📌 Parlay

  • Combine two or more bets into one for a higher payout.

  • Every bet (leg) must win for the parlay to cash.

  • Example:

    • Bet the Chiefs -6.5 AND Over 45.5 → Both must hit.

Parlay payouts increase based on the number of legs and the odds for each.


📌 Teaser

  • Special type of parlay where you move the point spread in your favor.

  • Example:

    • Move Chiefs -6.5 down to -0.5 to make it easier to win.

Because teasers are easier to hit, the payouts are smaller than standard parlays.


📌 Prop Bet (Proposition Bet)

  • Bet on specific outcomes inside a game.

  • Examples:

    • "Patrick Mahomes to throw over 2.5 touchdowns" (-120).

    • "First touchdown scorer: Travis Kelce" (+500).

Props have their own individual American odds.


📌 Futures

  • Bet on a long-term event or outcome.

  • Example:

    • "Chiefs to win the Super Bowl" at +600.

You place the bet now and wait for the outcome at the end of the season.


📌 Live Betting

  • Place bets after the game has already started.

  • Odds constantly shift during the game based on real-time action.

Example:

  • After the first quarter, Chiefs are down 7-0. Their live odds move from -150 pregame to +120.
