How to Use Public Betting Percentages to Win Bets

Gaining an edge over the sportsbooks is no small feat. Yet, one of the most overlooked tools for doing just that is understanding how to use public betting percentages to win bets. While many casual bettors blindly follow the crowd, there are many sports handicappers that know how to interpret public sentiment and use it strategically to identify value and make smarter wagers. In this guide, we’ll explore the concept of public betting percentages, how they work, why they matter, and how to integrate them into your overall handicapping process.

What Are Public Betting Percentages?

Public betting percentages refer to the proportion of total bets placed on each side of a matchup. Sportsbooks and data aggregators track this information to see how the betting public is wagering. Two primary data points are commonly discussed:

• Bet Percentage: This is the percentage of total individual wagers on a particular side of a game. For example, if 75% of bets are on Team A and 25% are on Team B, then Team A has a 75% bet percentage.
• Money Percentage: This refers to the percentage of total money wagered on a particular side. If 55% of the money is on Team A but only 25% of the bets are, that suggests larger wagers (often from sharper bettors) are backing Team A.

While both metrics are useful, money percentage often offers better insight into where the sharp money is going, while bet percentage reveals where the casual public is leaning.

Why Public Betting Data Matters

Public betting data matters because it offers a window into the behavior of the average bettor. Sportsbooks don’t just set lines based on predictions of game outcomes – they also set lines to balance their risk and attract action on both sides. When public sentiment heavily leans in one direction, sportsbooks may “shade” or adjust the line to make the less popular side more attractive and to manage their exposure.

For example, if 80% of bettors are on the Dallas Cowboys -3, the sportsbook might move the line to -3.5 or even -4 to encourage bets on the opponent and reduce liability. This line movement isn’t always based on team news or sharp analysis – it can be a reaction to betting volume alone.

The Concept of “Fading the Public”

“Fading the public” means betting against the majority. The rationale is that the public—driven by media narratives, popular teams, and recency bias – is often wrong, especially in marquee games where casual bettors are highly active.

A well-cited data source for this concept is the Action Network and Sports Insights (a part of Action Network), which have published findings on how public betting trends correlate with outcomes. One such trend showed that teams receiving less than 30% of bets covered the spread at a profitable rate – roughly 54-56% – over many seasons, particularly in NFL and NCAA football. However, this figure varies by sport, season, and line movement, and should not be treated as a guaranteed edge.

This strategy tends to work best in high-profile matchups, like Sunday Night Football or playoff games, where public money floods in on favorites or popular franchises. Overvalued teams like the Cowboys, Packers, Lakers, or Yankees often attract heavy action from the public, pushing lines in their direction and potentially creating value on the other side.

How to Access Public Betting Percentages

There are a number of sources for accessing public betting data:

Free Sources

• Vegas Insider – Offers consensus betting percentages from major sportsbooks.
• Oddshark – Provides a public betting breakdown and matchup analysis.
• DraftKings and FanDuel Sportsbooks – Sometimes offer public trends in their betting insights section.

Paid Sources

• Action Network (formerly Sports Insights) – Provides real-time bet and money percentages, line movement history, and sharp money indicators.
• VSIN (Vegas Stats & Information Network) – Offers betting splits and insider commentary.
• WagerTalk and SportsMemo – Deliver betting data along with expert analysis.

Pros and Cons:

• Free tools offer basic access to public percentages, but may not show money percentages or sharp money indicators.
• Paid tools offer more context, such as reverse line movement, line history, and sharp bet alerts, which can add a lot of value for serious bettors.

Mistakes to Avoid When Using Public Betting Data

While public betting data is useful, it’s not foolproof. Here are some common pitfalls to avoid:

1. Blindly Fading the Public

Just because 75% of bets are on one team doesn’t automatically mean you should take the other side. Context matters. Look for line movement that contradicts the betting percentages. This is where the concept of reverse line movement comes in – if most bets are on Team A but the line moves in favor of Team B, it may indicate sharp money is backing Team B.

2. Ignoring Sharp Money Signals

Sharp bettors typically wager larger amounts, earlier in the week, and influence the line more significantly than casual bettors. If 60% of bets are on one team but 70% of the money is on the other, that’s a strong signal that informed money disagrees with the public.

3. Overreacting to Small Sample Sizes

Don’t overreact to a single game or short-term trend. Look for consistent patterns across hundreds or thousands of games before forming conclusions.

Combining Public Betting Data with Other Metrics

Public betting percentages become even more powerful when combined with other factors:

• Line Movement – Is the line moving toward or away from the public side?
• Injury Reports – Are key players injured or returning?
• Weather – Rain, snow, or high wind can drastically affect scoring in football and baseball.
• Historical Matchups – Do teams have trends against the spread (ATS) in past meetings?
• Situational Angles – Travel, back-to-back games, or letdown spots can matter.

Example: If the public is on the Over in a Monday Night Football game and 80% of the bets back it, but the total drops from 47.5 to 46, that reverse movement—combined with rainy weather and a history of low scoring between the teams—could be a great spot to take the Under.

How to Use Public Betting Percentages in a Broader Handicapping System

Public betting data should never be the only tool in your arsenal. Instead, use it as a compass to guide further research.

Here’s a step-by-step approach:

1. Check bet and money percentages.
2. Analyze line movement for sharp or reverse indicators.
3. Evaluate injuries, weather, and scheduling spots.
4. Compare with your own power rankings or projections.
5. Make a decision only when the data aligns.

Conclusion

Learning how to use public betting percentages to win bets is about more than just fading the crowd – it’s about understanding why the crowd is on one side and whether that sentiment is justified. While historical data from sources like Action Network suggests that going against public betting trends can be profitable in the right context, this strategy requires discipline, research, and a willingness to go against the grain.

Used properly, public betting data can be a valuable piece of your handicapping puzzle. Blend it with sharp line analysis, situational trends, and other data points, and you’ll be on your way to making more informed – and more successful – bets.
