Sports betting is more than just a game – it's a science. If you're a sports bettor, you might have heard of "Positive EV Betting", but do you understand what it truly means and how it can exponentially increase your winnings in the long run? This guide will walk you through the concept of Positive Expected Value (+EV) betting and why it's essential for your betting strategy. Whether you're a seasoned bettor or new to the scene, understanding Positive EV can be your ticket to long-term profitability.

What is Positive EV?

Positive Expected Value, or Positive EV (+EV), is a betting strategy that focuses on placing bets where the probability of winning is higher than what the sportsbooks estimate. In simpler terms, it's about finding the "edge" where the odds are in your favor. The concept of Expected Value is central to determining whether a bet is likely to be profitable in the long run. It is calculated by multiplying each potential outcome by the probability of its occurrence, then summing these results. A positive expected value indicates a bet that should result in profit over time, while a negative EV points to expected losses.

Breaking it Down

Imagine betting on a coin flip with a fair coin that gives you a 50% chance for heads and tails. If the sportsbook offers -110 odds on either outcome, you're at a disadvantage due to the vig (house edge). But what if you knew the coin was slightly weighted to land on heads 55% of the time? In this case, even with the same -110 odds, consistently betting on heads means you're stacking the odds in your favor. This is Positive EV—betting when you have an edge, ensuring long-term profitability despite the inherent vig.

How Does it Work in Sports Betting?

In sports betting, Positive EV is calculated by comparing the sportsbook's odds to the actual fair odds (true probability) of an event occurring. For instance:

1. Odds Comparison - Suppose a sportsbook offers +150 odds on a team to win (You win 1.5x your money if you win). NexusOdds' Positive EV tool calculates the fair odds for the team to win should be +130.
2. Profitability - This discrepancy indicates there's a higher probability of the event happening than the sportsbook predicts, making it a profitable bet in the long run.

How to Calculate Expected Value

Calculating expected value might sound complex, but it's straightforward once you grasp the formula:

If the resulting EV is positive, you've found yourself a profitable bet.

Example of Calculating Expected Value

Let's run through an example of calculating expected value using our previous equation. We have a bet on the St. Louis Cardinals for the 1st 5 Innings moneyline at +130 odds. If we convert the American odds to a probability, the sportsbook is implying that there's a 43.48% chance of the Cardinals winning. However, NexusOdds has calculated the fair odds for this bet, determining the true probability of the event occurring to be 46.65%. Using the Kelly Criterion, we find that the optimal bet size for this opportunity is $140.

Now, let's plug these figures into the EV equation:

Calculating this gives us:

This means we can expect to make $10.21 every time we place this bet over the long run. To convert this expected value dollar amount into a percentage, we calculate:

Thus, by consistently placing this bet, we can expect a return of approximately 7.3% over time, marking it as a positive expected value opportunity.

The Importance of Positive EV Betting

Long-Term Profitability

The key to successful sports betting isn't about winning every single bet; it's about making bets with a positive expected value over time. This means that while you may lose some bets, winning enough higher-value bets will help you come out ahead in the long run. It's crucial to understand that positive EV betting requires a long-term perspective. While short-term losses are inevitable due to the variance in sports outcomes, maintaining a mathematical edge should theoretically lead to profitability over an extended betting period.

Turning the Odds in Your Favor

Sportsbooks set their odds in such a way that they have a built-in advantage (the vig). Positive EV betting helps you identify opportunities where this advantage is reversed, favoring you instead of the house.

Making Informed Decisions

Positive EV betting encourages you to think analytically rather than emotionally. By focusing on bets with a positive expected value, you're making informed decisions based on data and statistics, rather than gut feelings or biases.
