The Best Sports Betting Strategies: Winning +EV Systems That Work

Updated February 9, 2025 | 10:01 am CDT by Sam Smith
Best Sports Betting Strategies: Winning +EV Systems That Work

Sports betting has evolved from casual wagers into a data-driven industry where sharp strategies can significantly improve your odds of long-term success. Popular betting methods like moneyline betting, spread betting, parlays and value betting are the cornerstone of most profitable systems. In this guide, we’ll explore these strategies using principles from Portfolio EV.

Best Sports Betting Strategies: Winning +EV Systems That Work

Moneyline Betting: Keep It Simple

Moneyline betting is the simplest and most common form of sports betting, where you bet on which team or player will win outright. It’s ideal for beginners and a critical component of advanced strategies.

  • A favorite will have negative odds (e.g., -150), meaning you need to bet $150 to win $100.
  • An underdog will have positive odds (e.g., +200), meaning you win $200 for a $100 bet.

Tips for Moneyline Betting Success

  • Shop for the Best Lines: Odds vary across sportsbooks, so use Portfolio EV to compare odds and find the most profitable bets.
  • Avoid Heavy Favorites: While they might feel safe, consistently betting on heavy favorites offers little value and can erode your bankroll during inevitable losses.
  • Target Underdogs with Value: Focus on underdogs whose odds are higher than their true probability of winning, as determined by sharp sportsbooks.

If a team is +200 but has a 40% chance of winning (implied odds = +150), betting on them offers positive expected value (+EV).

Spread Betting: Level the Playing Field

Spread betting involves wagering on a team to win or lose by a specific margin. It’s particularly popular in sports like football and basketball, where games can be lopsided.

  • A spread of -6.5 for a favorite means they need to win by 7 or more points to cover.
  • A spread of +6.5 for an underdog means they must lose by 6 or fewer points — or win outright — for the bet to cash.

Tips for Spread Betting Success

  • Key Numbers Matter: In football, focus on key numbers like 3 and 7, which represent common scoring margins.
  • Monitor Line Movement: Line shifts can signal sharp action. For example, if a spread moves from -6.5 to -7, it might indicate sharp bettors backing the favorite.
  • Pair Spreads with Totals: Use the game’s total points to inform your spread bets. For example, a low-scoring game favors underdogs covering spreads.

The Eagles are -3.5 favorites against the Cowboys. If you believe the Eagles will win by at least 4 points, you bet on the Eagles to cover the spread.

Parlay Betting: High Risk, High Reward

Parlay betting combines multiple bets into one ticket, offering exponentially higher payouts — but with significantly higher risk.

  • Each selection in a parlay (called a “leg”) must win for the ticket to cash.
  • Odds for individual bets are multiplied, creating large potential payouts.

Tips for Parlay Betting Success

  • Limit the Number of Legs: The more legs, the lower your chance of winning. Stick to two- or three-leg parlays for a balance of risk and reward.
  • Focus on Correlation: Combine bets that are statistically related, like betting on a quarterback’s passing yards over and his team covering the spread.
  • Hunt for +EV Legs: Use Portfolio EV to ensure each bet in your parlay has positive expected value.

You create a three-leg parlay:

  • Chiefs -7 (-110)
  • Over 48.5 points (-110)
  • Travis Kelce to score a touchdown (+125)

If all three bets win, you’ll receive a payout calculated by multiplying the odds.

Value Betting: The Foundation of Winning Systems

Value betting is a professional bettor’s bread and butter. It involves identifying bets where the sportsbook’s odds don’t accurately reflect the true probability of an event.

  • Determine the “true odds” of an outcome using Portfolio EV.
  • Compare these true odds to the odds offered by your sportsbook.
  • Bet when there’s a discrepancy in your favor (i.e., when the implied probability is lower than the true probability).

Tips for Value Betting Success

  • Track Your Bets: Consistently monitor results with a Bet Tracker to ensure your strategy is profitable.
  • Use Multiple Sportsbooks: Expanding your options increases the chances of finding mispriced lines.
  • Leverage Market-Maker Odds: Sharp books like Pinnacle and Circa often have the most efficient lines. Use their odds as a baseline to identify market inefficiencies.

If a sportsbook offers +120 on a team you calculate has a 50% chance of winning (implied odds = +100), that bet is +EV and worth placing.

Leverage Portfolio EV for Winning Betting Strategies

Portfolio EV simplifies the process of finding +EV bets by identifying inefficiencies across multiple sportsbooks. It tracks odds in real time, helping you build a portfolio of profitable wagers with minimal effort. With Portfolio EV’s data-driven approach, you can maximize your edge and grow your bankroll sustainably.

Final Thoughts

Whether you’re new to sports betting or looking to refine your strategy, understanding these popular systems is crucial for long-term success. Stick to value-based principles, stay disciplined and leverage Portfolio EV to find consistent edges in the market.
