If you’re serious about making money in sports betting, understanding expected value betting (+EV) is crucial. Many recreational bettors focus on picking winners, but professional bettors focus on finding edges — small advantages that compound over time. Below we break down common +EV sports betting FAQs, teaching you how to leverage Portfolio EV principles to help you maximize your returns.

What is +EV betting?
Positive expected value betting — or +EV betting — refers to placing wagers where the odds offer better value than the true probability of the outcome. This means you’re consistently getting more than you should, based on fair market odds. Over time, placing only +EV bets leads to profitability, even with some variance along the way.
For example, if a bet has a true probability of 50% (fair odds of +100) but a sportsbook offers it at +110, this is a +EV bet because you’re getting a price better than fair value.
How do I find +EV bets?
Finding +EV bets requires two key steps:
- Understanding true odds – This often means comparing odds across multiple sportsbooks or using advanced tools like Portfolio EV to locate the best prices.
- Targeting inefficient markets – Market-making sportsbooks (like Pinnacle or Circa) set the sharpest lines. If a soft book lags behind, that’s where the edge is.
What is a market-making sportsbook, and why does it matter?
Market-making sportsbooks set the lines rather than copying from others. These books take sharp action, adjust accordingly, and establish the most efficient odds. Non-market-making sportsbooks often just move their lines based on the big books — creating opportunities for +EV bettors to exploit discrepancies.
Example: If Pinnacle has an NFL spread at -3 (-110) but a soft book offers -2.5 (-110), betting the -2.5 is a +EV move since you’re getting a better number at the same price.
Should I bet on every +EV opportunity?
No — bankroll management is key. The best approach is a portfolio strategy, where you spread your bets across multiple edges, much like a diversified investment portfolio.
Using Portfolio EV tools, you can track your expected returns across different bets and stakes, ensuring you’re maximizing your edge without overextending yourself.
What is CLV (Closing Line Value), and why is it important?
Closing Line Value (CLV) is the measure of how your bets compare to the final odds at a sharp sportsbook. If you consistently beat the closing line (i.e., you bet a team at -110 and it closes at -125), that indicates long-term profitability. Winning bettors prioritize getting the best number rather than just picking winners.
Should I always bet the best available odds?
Yes — always compare odds across multiple sportsbooks. Even a small difference, like betting at +105 instead of +100, increases your long-term profitability. Over thousands of bets, small edges compound significantly.

How do sportsbooks adjust lines, and how can I take advantage?
Sportsbooks adjust lines based on:
- Sharp action – If respected bettors hammer one side, the book will move the line.
- Public money – Recreational bettors influence movement, especially in big markets (NFL, NBA).
- Injury/news updates – A key player being ruled out can shift the odds significantly.
How to take advantage:
- Bet early if you think the line will move in your favor.
- Bet late if you want to fade public overreaction.
- Monitor movement on market-making books and pounce on soft books that lag behind.
What’s the difference between a sharp and a square bettor?
A square bettor places bets based on gut feeling, narratives or team loyalty. A sharp bettor:
- Shops for the best odds
- Finds +EV opportunities
- Understands market movement
- Tracks their results and CLV
What bankroll strategy should I use for +EV betting?
The Kelly Criterion is a popular staking strategy that helps you determine how much to wager based on your edge. A flat-betting strategy (betting the same unit size per wager) is also effective for reducing risk and avoiding bankroll swings.
What’s the best way to manage variance and downswings?
Variance is inevitable—even sharp bettors experience losing streaks. The key is to:
- Stick to +EV bets and trust the long-term math.
- Track your bets (not just wins/losses, but how often you beat closing lines).
- Stay disciplined with staking — don’t chase losses or bet beyond your means.
