What Is Peer to Peer Gambling?
Peer to peer gambling allows bettors to wager against each other rather than against a traditional sportsbook. Instead of the house setting odds and taking positions, a betting exchange matches users who want opposite sides of a bet. The exchange takes a small commission on winning bets instead of building in a vig. I first used betting exchanges in 2023 when exploring alternatives to traditional sportsbooks, and the experience opened my eyes to a different way of approaching sports betting. This guide explains how P2P gambling works, when it offers advantages, and which platforms are available to U.S. bettors.
article Summary
Peer to peer gambling through betting exchanges lets users bet against each other instead of a sportsbook. Exchanges typically offer better odds since there is no traditional vig, charging a commission on wins instead. Major platforms include Betfair (internationally) and emerging U.S. options like Prophet Exchange and Sporttrade.
How Betting Exchanges Work
Understanding the mechanics of betting exchanges helps you evaluate whether they fit your betting style.
Matching Bettors Instead of Taking Positions
Traditional sportsbooks act as the counterparty to your bet. If you bet on the Chiefs, the sportsbook effectively bets on the Chiefs losing. Betting exchanges work differently. When you place a bet, the exchange matches you with another user who wants the opposite outcome. If you want the Chiefs at +3, someone else must want the opponent at -3 for the bet to be matched.
Back and Lay Betting
Exchanges introduce a concept called laying. You can "back" an outcome (bet that it will happen) or "lay" an outcome (bet that it will not happen). Laying is essentially taking the sportsbook's role. If you lay the Chiefs at +3, you are betting they will not cover. This flexibility opens strategies unavailable at traditional books.
Commission Structure
Exchanges charge a commission on net winnings, typically 2-5%. This is different from the vig built into sportsbook odds. Because users set the odds rather than the house, exchange prices often reflect true probabilities more closely, sometimes offering better value than traditional books.

Advantages of Peer to Peer Gambling
Betting exchanges offer several structural advantages over traditional sportsbooks for certain types of bettors.
Better Odds
Because there is no house taking a position, exchange odds often approach true probabilities. A market priced at -110/-110 at a sportsbook might be -102/-102 or even +100/-100 on an exchange. Over thousands of bets, these improved odds significantly impact long-term profitability.
No Account Restrictions
Traditional sportsbooks limit or ban winning bettors because they lose money to sharps. Exchanges welcome all bettors because they profit from commission regardless of who wins. If you have been limited at DraftKings or BetMGM, exchanges offer an alternative where your winning action is accepted.
Ability to Lay Bets
Laying lets you profit when you expect an outcome NOT to happen. If you think a heavy favorite will struggle but do not know if the underdog will win outright, laying the favorite's spread lets you bet against them covering without needing the underdog to win. This flexibility is unique to exchanges.
Trading Positions
Some exchanges allow you to "trade" by backing at one price and laying at another as odds move. This is similar to trading stocks. You can lock in profit or cut losses before an event settles, a capability not available at traditional sportsbooks.
Disadvantages and Considerations
Betting exchanges are not perfect. Understanding the limitations helps you decide when to use them.
Liquidity Constraints
For a bet to execute on an exchange, another user must want the opposite position. Popular markets like NFL spreads have plenty of liquidity, but niche sports or player props may have limited matching. If no one takes the other side of your bet, it does not get placed.
More Complex Interface
Exchanges require understanding concepts like backing, laying, and order books. The learning curve is steeper than traditional sportsbooks. My first experience with an exchange was confusing until I spent time practicing with small stakes.
Limited Availability in the U.S.
Betting exchanges have operated internationally for decades (Betfair is the largest globally), but U.S. options are newer and more limited. Prophet Exchange and Sporttrade are emerging platforms, but they are not available in every state. The market is growing but still less mature than traditional sportsbooks.
P2P Gambling Platforms for U.S. Bettors
If you are interested in peer to peer gambling, here are the main options available to U.S. bettors in 2026.
Prophet Exchange
Prophet Exchange launched as one of the first U.S. betting exchanges. It offers back and lay betting on major sports with competitive commission rates. The platform is designed for bettors familiar with exchange concepts, though it provides educational resources for newcomers.
Sporttrade
Sporttrade positions itself as a sports trading platform, emphasizing the ability to buy and sell positions on games. The interface resembles a stock trading app, appealing to users comfortable with that paradigm. It offers low commission rates and focuses on major U.S. sports.
Prediction Markets
While not traditional betting exchanges, prediction markets like Polymarket and Kalshi allow peer to peer wagering on event outcomes, including sports. These operate differently from exchanges but share the P2P principle. They are worth exploring for bettors interested in alternative betting structures.
When to Use Betting Exchanges
Exchanges are not a replacement for traditional sportsbooks but a complement. Here is when they add the most value.
If You Have Been Limited
Sharp bettors who face restrictions at traditional books can move their action to exchanges where winning is welcomed. This is often the primary reason professionals use exchanges, they can bet without limits on their stake size.
For Better Odds on Popular Markets
On heavily bet markets like NFL spreads, exchange odds are often better than any sportsbook. Comparing exchange prices to your sportsbook options using line shopping tools ensures you always get the best available number.
When You Want to Lay
If you have conviction that a favorite will underperform but are not confident the underdog wins outright, laying offers a way to bet that thesis. Traditional sportsbooks do not offer this option.
As Part of a Diversified Approach
Having accounts at both traditional sportsbooks and exchanges gives you maximum flexibility. Use the exchange when it offers better odds; use sportsbooks when liquidity or convenience matters. A bet tracking app helps you manage bets across multiple platforms.
Final Thoughts
Peer to peer gambling through betting exchanges offers a fundamentally different approach to sports betting. By matching users instead of taking house positions, exchanges often provide better odds and welcome winning bettors. The trade-offs are liquidity constraints, more complex interfaces, and limited U.S. availability compared to traditional sportsbooks. If you are a sharp bettor facing account restrictions, or simply want the best possible odds on major markets, exploring exchanges is worthwhile. Start with small stakes to learn the mechanics, and use exchanges as one tool in a broader betting strategy that includes traditional books.
