Prop bets have evolved from a rare courtesy offered by Las Vegas sportsbooks to a centerpiece of the sports betting industry over the past few decades.

Their popularity stems from an increasing desire among bettors to wager on more than just the outcome of a game. And sportsbook operators are happy to oblige because more bets equal more action.

Today, prop bets comprise the majority of betting markets on legal betting apps, and their reach expands with every passing year.

Props also present unique opportunities for savvy bettors, who realize bookmakers can’t possibly post accurate lines for hundreds of novelty bets.

So, what is a prop bet, and how exactly should bettors approach sports props?

Prop Bets Explained

Put simply, prop bets – otherwise known as proposition bets – are wagers not directly tied to a game outcome or season-long result. If it’s not a point spread, total, moneyline, or future, it’s probably a prop bet.

Modern sports fans want to wager on more than just the outcome of the next game. They want to bet on their favorite players, teams, and what will happen in the 1st quarter, or even the opening drive of a football game. Props satisfy that craving.

Props commonly ask YES/NO type questions, and these questions range from pedestrian, like “How many total points will the home team score?” to exotic, such as “What color will the Gatorade shower be?”

As the prop market has grown, several prop subdivisions have emerged, each sharing certain characteristics but also exhibiting key distinctions.

Game Props

Game props are often derivatives of full game bets. As long as the wager doesn’t revolve around an individual player performance, it’ll probably fall in the game prop bucket.

For instance, NFL and NBA bettors can wager on the 1st half spread and moneyline or the 2nd quarter total. Other sportsbooks take game props a step further and offer more exotic bets like:

  • Will there be a safety or a successful 2-point conversion?
  • How many 3rd downs will both teams successfully convert in total?
  • What will be the largest lead of the game?
  • What will be the last scoring play of the first half?
  • How many total field goals will there be?
  • What will be the exact score after two innings?

The list goes on, and as demand grows, books must become more imaginative with each passing season to keep up with the competition.

Team Props

As the name implies, team props pose questions tailored around team performance. Common examples include total team touchdowns or field goals in an NFL game and team rebounds or assists in an NBA game.

Other team prop examples include:

  • Which team will score the first touchdown? (NFL)
  • Which team will reach 30 points first? (NBA)
  • Will a team finish with an odd or even number of runs? (MLB)

Player Props

The application of data analytics to professional sports has increased in prominence among fans, and as a result, their interest in betting on player statistics has also spiked.

Sportsbooks capitalize on the demand by offering dozens of prop bets on individual players, with an emphasis on critical positions in football (QB, running back, etc.), baseball (pitcher, power hitter), and celebrities in other sports, such as Lebron James in the NBA.

Standard player props may cover questions such as:

  • How many passing yards or passing touchdowns will a QB have?
  • Will a star wide receiver have over or under 7.5 receptions?
  • How many assists will a player have in his next NBA game?
  • How many strikeouts will a pitcher have?

The scope of player props varies among sportsbooks, with the more aggressive books offering player props on just about every statistic or combination of statistics.

Exotic Props

Novelty props are less common than other types of proposition bets. Bettors find exotic props most often during the run-up to high-profile events like the Super Bowl.

Exotic Super Bowl prop bets have little to do with the actual game. Instead, they’re wagers on minute details surrounding the event. Examples include:

  • What will be the length of the national anthem?
  • Will the coin toss come up heads or tails?
  • What color of Gatorade will the winning team pour on its coach?
  • Who will be crowned the Super Bowl MVP?
  • How many times will the camera pan over to the head coach?

Exotic prop bets can even extend to non-sporting events like the Oscars and political elections, although wagering on the latter is not yet permitted in the United States.

How to Place Prop Bets Online

Bettors can find the greatest abundance of sports betting props via legal betting apps and online sportsbooks. Finding and placing props is easy, although the process varies slightly from one sportsbook to the next.

We’ll use FanDuel Sportsbook as an example since it offers more proposition bets than just about any of its competitors:

  1. Log in to the FanDuel sports betting app or website
  2. Navigate to a sport that’s likely to feature a wealth of prop bets, typically NFL, NBA, MLB, college football, or college basketball – FanDuel and other sportsbooks also often list popular in-play props directly on the homepage
  3. Tap or click a game, and visit the “props” tab, usually near the top of the game page
  4. Select a prop category (passing props, rushing props, player props, etc.)
  5. Tap or click a prop bet to add it to the bet slip and select an amount to wager

Bettors can expect to find quirks in how each sportsbook manages and displays prop bets. For example, when users select “QB Props” on DraftKings Sportsbook, the app displays quarterback props available for every game in the NFL. In other words, DraftKings filters by prop category first and game second, whereas most other sports betting apps do it the other way around.

Are Props Good Bets?

Props are a sportsbook’s best friend and worst nightmare.

Proposition bets usually derive from an efficient line, often a total or point spread. For instance, if an NFL game total is 54 and the spread is +2.5 / -2.5, it stands to reason that both quarterbacks will be piling up a lot of passing yards. Thus, QB totals props will skew high.

However, there is less certainty that one QB will have a big game than there is both teams combining for a ton of points. More novel props are subject to even greater degrees of uncertainty because the correlations with efficient lines are loose.

Additionally, props are in such high demand that books have to offer more of them to remain competitive. With more props comes a greater likelihood of errors.

Oddsmakers account for this uncertainty with several methods. First, sportsbooks juice props more than other lines. Whereas -110 American odds are industry standard on point spreads and totals, YES/NO prop bets skew more toward -115 or even -118.

In addition, prop betting limits are often low – sometimes laughably so. For example, if a sportsbook limits a bettor to $1,000 max on point spread wagers, it might restrict that same player to $50 on props. In some cases, the limit can be as low as $5 or less.

Finally, some books offer one-way props. Whereas two-way props are YES/NO questions, one-way props only allow bettors to bet on YES. Bookmakers know the public’s tendency to bet on favorites and overs, so they use one-way props as a vehicle to squeeze a bit extra out of their customers.

All that said, props are still highly beatable, more so than any other betting market. Sometimes all it takes is a bit of line shopping to find a book that offers drastically different prop prices than its peers. Always shop around when scouring prop markets.

Another tip is to see how prop markets react when primary lines move. For example, if an NBA game total drops by 3.5 points due to a player injury, and correlated props don’t move accordingly, it may be time to pounce.

Just be cognizant that books don’t post their prop menu until well after the primary lines go live. This could mean Wednesday or Thursday for NFL Sunday games or the late morning on game day for NBA. Books may decide only to post few if any props for smaller markets like lesser-known college sports conferences.

Prop Betting FAQ

Yes. There is nothing stopping bettors from parlaying multiple props from different games together.

Some books even take this further and allow bettors to parlay prop bets from the same game. Correlated parlays – otherwise known as same game parlays – have grown increasingly popular of late, and their scope now includes a variety of prop bets.

As is the case with traditional parlays, same game parlays possess a high house edge. The more parlay legs added, the higher the house edge swells.

Often, the vigorish on same game parlays is even higher than regular parlays. Casual bettors really have no way of knowing because sportsbooks calculate the impact of correlation behind the scenes. Beyond that, some books don’t even display individual leg odds for their same game parlays.

However, some sportsbooks do provide the odds on each leg. For example, the Caesars Sportsbook app displays each leg’s odds:

Caesars Sportsbook props

Most sportsbooks support in-play prop betting. Examples of live-betting props include:

  • Who will score the next touchdown?
  • How many rushing yards will a running back achieve?
  • Will the next drive result in a score?
  • Will the next batter strike out?

As evidenced, in-play props are just an extension of regular props. The main difference is that the lines fluctuate frequently and are dictated by what’s already happened during the game.

In-play props may be the least efficient bets in all of sports betting because they combine two betting formats subject to high degrees of uncertainty. As a result, there are plenty of opportunities for bettors to take advantage.

The sports with the greatest variety of prop betting opportunities share the following characteristics:

  • High Scoring
  • Critical positions
  • High profile star players
  • Market popularity

This list is not inclusive but should give bettors a general idea of which markets offer the most props.

For example, scoring is plentiful in the NFL, the quarterback position is arguably the most important in all of sports, and the biggest stars receive Hollywood celebrity treatment. So, it’s of little surprise that books offer dozens, if not hundreds, of proposition bets on every single NFL game.

The NBA also meets these criteria. Scoring is even higher than the NFL, every position is important, and even casual fans can name the league’s top players.

It goes without saying that both the NFL and NBA are extremely popular. It’s gotten to the point where bettors feel shortchanged if the book doesn’t support pages upon pages of NFL and NBA props.

Moving down a rung are college football and basketball, which lack the star power of their professional counterparts. MLB used to fit into this second-tier category, but books have recently shown a willingness to expand their menu of baseball props. In particular, pitcher strikeout totals and player home run props have become widespread.

Bettors will also find prop bets on soccer, golf, tennis, and hockey, but they’re not nearly as abundant.

It’s worth noting that without recent advances in sports betting technology, especially in the online space, sportsbooks wouldn’t be able to offer as many props. Today’s prop markets may not be nearly as efficient as spread or totals markets, but they’ve evolved beyond convenience bets.
