Sports prediction markets use a peer to peer exchange model where users trade event shares against each other, whereas traditional sportsbooks act as the house by taking the opposite side of every bet. In a prediction market, share prices shift between $0.00 and $1.00 based on user supply and demand. This structure lowers trading fees to around 2% and allows participants to exit positions before an event ends.

Key takeaways
- Sportsbooks act as the house counterparty profiting from user losses, while prediction markets use a peer to peer exchange model to match buyers and sellers.
- Prediction market platforms charge transaction fees around 2%, whereas traditional sportsbooks embed a vig of nearly 10% directly into their betting odds.
- The Commodity Futures Trading Commission regulates prediction markets federally as financial derivatives, while state gaming laws govern traditional sportsbooks on a state level.
Exchange Model vs the House
The most foundational difference between a sports prediction market and a traditional sportsbook lies in who takes the other side of the trade. Traditional sportsbooks operate on a “house” model. When a user places a wager on a football match or a basketball playoff game, they are betting directly against the sportsbook itself. The house sets the odds, manages its risk, and profits when the user loses. If a large number of users win their bets, the sportsbook takes a financial hit, which incentivizes the house to continuously adjust lines to balance their books or limit the accounts of highly successful bettors. The sportsbook is a counterparty to every single transaction, acting as the centralized market maker and risk absorber.
Prediction markets, conversely, operate on an exchange model, specifically a peer-to-peer (P2P) architecture. Platforms like Polymarket, which handles over $2 billion in annual volume on the Polygon network, and Kalshi, which processes over $1 billion annually with heavy institutional participation, do not take the other side of a user’s forecast. Instead, they function purely as neutral matching engines. If a user believes a specific tennis player will win a major tournament, they must buy “Yes” shares from another user who is willing to sell them, or who is buying “No” shares. Supply and demand drive the price of these shares, which fluctuates between $0.00 and $1.00. This crowdsources the probability of an event. When an event concludes, the winning shares resolve at $1.00, and the losing shares resolve at $0.00.
Because prediction markets function as exchanges, they offer a critical feature rarely found in traditional sportsbooks: the ability to easily trade in and out of positions before an event has concluded. If a user buys shares in a baseball team to win a championship at $0.20 (implying a 20% probability), and the team goes on a winning streak causing the shares to rise to $0.60, the user can sell their shares to lock in a profit instantly. While some sportsbooks now offer “cash out” features, these are heavily penalized with poor margins set by the house. In a prediction market, liquidity dictates the price, allowing for dynamic, continuous trading similar to a stock or commodities exchange. This exchange model aligns platform incentives with market efficiency instead of user losses. This alters the user experience.
Apps such as Swipe1 are built specifically to make this kind of forecasting accessible from a phone, without a trading interface to learn.
Fees: 2% Cut vs Traditional Vig
The divergent architectures of prediction markets and sportsbooks directly dictate their fee structures, which drastically impacts the long-term profitability and economics for the user. In the traditional sports betting industry, the cost of participating is embedded in the odds through a mechanism known as the “vig” or overround. Because the sportsbook is taking on the risk of paying out winning bets, they build a mathematical edge into the lines. For a standard spread bet, both sides of an outcome are typically priced at -110, meaning a bettor must risk $110 to win $100. This built-in margin ensures that if action is balanced on both sides, the sportsbook is mathematically guaranteed to keep nearly 10% of the total pool. Over time, this high vig creates a significant drag on the user’s capital, requiring them to win at a much higher rate just to break even.
Prediction markets, operating as neutral facilitators, do not need to build risk premiums into the prices. Instead of a vig, they charge a transparent transaction fee or a small percentage of profits. For instance, Polymarket has historically operated with fees around the 2% mark, drastically undercutting the traditional 10% sportsbook vig. Because users are trading against each other, the market organically discovers the true probability without a centralized entity extracting a heavy premium to cover its own exposure.
| Feature | Traditional Sportsbook | Sports Prediction Market |
|---|---|---|
| Market Maker | The House (Centralized) | Peer-to-Peer (Decentralized/Exchange) |
| Fee Structure | ~10% Vig built into odds | ~2% Transaction/Trading fee |
| Position Management | Locked (or penalized cash-out) | Dynamic trading (buy/sell anytime) |
| Incentive Alignment | House profits from user losses | Platform profits from trading volume |
| Regulatory Status | State Gaming/Gambling Laws | Commodity Futures Trading Commission (CFTC) |
This lower fee environment is a primary driver behind the massive influx of capital into prediction markets, pushing open interest in the industry to around $1.3 billion by mid-2026. The efficiency of a low-fee exchange model attracts not just casual fans, but also institutional capital and algorithmic traders who provide liquidity. The result is a highly competitive, efficient market where the prices reflect a much more accurate consensus of probability, untainted by the heavy operational overhead and risk mitigation costs of traditional sportsbooks.
Regulation: CFTC vs State Gaming Law
Perhaps the most complex and consequential difference between these two verticals is how they are treated under the law. Traditional sports betting in the United States is regulated on a state-by-state basis as gambling. Since the repeal of PASPA in 2018, individual states have created their own licensing regimes, tax structures, and compliance requirements. A sportsbook must get a gaming license in every state where it operates. This creates a split system where sports betting is legal in states like New Jersey, but banned in California and Texas.
Prediction markets for event contracts follow a different regulatory route: federal oversight as financial derivatives. Platforms like Kalshi operate under the jurisdiction of the Commodity Futures Trading Commission (CFTC), categorizing sports forecasts not as wagers, but as event contracts. Because they are federally regulated derivatives, Kalshi can legally operate in massive jurisdictions where traditional sportsbooks are banned, such as California and Texas. However, this regulatory pathway is not without friction. In January 2026, Massachusetts issued an injunction to block Kalshi’s sports contracts, and the CFTC itself is actively shaping the boundaries of the industry.
In June 2026, the CFTC published a 267-page draft regulation for prediction markets. It considers limits on sports contracts predicting player injuries or referee decisions to protect game integrity. Regulatory tension between federal and state authorities has grown. The CFTC is currently suing nine states, including New York, Illinois, and Arizona, to claim sole federal control over event contracts. In April 2026, the industry saw its first insider-trading case involving event contracts. This shows that regulators treat prediction markets with the same legal severity as financial and commodity markets. This distinction matters: sportsbooks are gaming operations run under state lottery or casino commissions, while sports prediction markets are financial exchanges regulated by the federal body overseeing oil and gold futures.
How Swipe1 Frames Sports Questions
As the prediction market industry matures into a multi-billion dollar financial sector dominated by heavy trading, complex order books, and institutional volume, a new wave of mobile-native platforms is emerging to serve everyday users. Swipe1 represents this exact evolution.
