Betting on U.S. elections through online platforms like DraftKings or FanDuel is prohibited, yet it can be done legally on prediction market sites across all 50 states. This shift illustrates the growing popularity of prediction markets, which saw over $44 billion in trading in the U.S. in 2025, with Kalshi and Polymarket alone accounting for $24 billion by April 2026. To the casual observer, prediction markets may seem similar to sports betting due to their overlapping platforms and operational frameworks. However, the distinctions are significant. This guide elucidates the main differences between prediction markets and sports betting.
**What is sports betting?**
Sports betting represents the conventional approach to wagering on ongoing sporting events. In this model, sportsbooks set the odds, accept bets, and pay winnings from their own reserves. Each wager is made against the house; when a bettor wins, the sportsbook pays out, but if the bettor loses, the sportsbook retains the stake. Odds are derived from statistical models and cash flow rather than reflecting true probability, with the themes available for betting primarily restricted to sports.
**What is a prediction market?**
In contrast, prediction markets facilitate the trading of contracts based on the outcomes of future events. Each contract pays $1 if the event occurs, and $0 if it does not. Unlike traditional sports betting, users trade with one another instead of against the house, providing a direct probability signal without hidden margins. Users also have the option to exit their positions before the event's conclusion. Prediction markets cover a broader range of topics, encompassing sports, politics, economics, technology, and entertainment. Kalshi and Polymarket are notable example platforms operating under the regulations of the Commodity Futures Trading Commission (CFTC).
**Key Differences**
While prediction markets and sports betting may appear similar, several key differences set them apart:
| Feature | Prediction Markets | Sports Betting |
|———|——————-|—————-|
| Market structure | Peer-to-peer, users trade contracts among themselves | House model, bets are placed against the bookmaker |
| Pricing & odds | Prices reflect probabilities, e.g., a $0.65 contract implies a 65% chance | Odds include a margin (4-10%), which affects implied probabilities |
| House edge | No house edge, with a transparent fee (1-2%) | Built-in disadvantages; the vig ensures profitability for the operator |
| Exit flexibility | Users can sell contracts before event completion | Bets fixed upon placement, with cashing out typically at a loss |
| Event scope | Broad, including sports, politics, and more | Limited mainly to sports events |
| Regulation (US) | Classified as financial derivatives, legal in all states | Legal in about 39 states with state-specific licenses |
| Key risks | Low liquidity in niche markets, regulatory uncertainty | Structural house advantage, limited pricing transparency |
**Pros and Cons**
Both models cater to different types of players. Traditional sports betting is suitable for enthusiasts who enjoy real-time betting and the excitement of live events. Prediction markets appeal to those interested in various outcomes and the option to trade positions freely.

**Choosing Between Them**
To determine which model suits you better, consider your goals. Users of prediction markets often focus on probabilities rather than solely winning or losing. They may assess broader circumstances, such as evaluating if inflation will rise by 3% this year.
Leading prediction market platforms include Polymarket and Kalshi, although the market is evolving with various applications integrating these features, including upcoming products from major companies like Meta. On the other hand, sports betting is straightforward, revolving around popular sports such as football, basketball, and tennis, with platforms like Bet365, DraftKings, FanDuel, and Betfair leading the way.
**Legality and Regulation**
Sports betting has been legal and regulated in the UK for over a century, overseen by the UK Gambling Commission (UKGC). Most European countries impose strict betting rules, resulting in a forecasted revenue drop from €353 million in 2024 to €286 million in 2025. Currently, 39 U.S. states allow sports betting, though large states like California, Texas, and Georgia prohibit it.
Prediction markets, classified under CFTC regulations in the U.S., operate legally in all states. Meanwhile, several European countries have restricted access to prediction market sites, and analysts suggest they may fall under betting intermediary categories in the UK and Ireland, where remote betting intermediary licenses are expected to be granted by mid-2026. While gaining traction in Europe, prediction markets are still categorized as gambling products.
