Complete comparison, expert explanation, legality, and how to choose the right prediction markets.
Prediction markets, also called event markets, idea futures, or information markets, let you buy and sell contracts tied to future event outcomes, from elections to the Super Bowl, economic indicators, pop culture moments, or weather metrics. Unlike traditional sportsbooks, these platforms create dynamic prices based on real-time market sentiment, often reflecting the collective forecast of traders.
What Is a Prediction Market App?
Prediction markets are exchange-style platforms where each contract’s price reflects the estimated probability of an event occurring. For example, if a contract trading whether “Team X wins next week” is priced at $0.65, the implied probability is 65%. If the event happens, winning contracts settle at $1; if not, they expire worthless.
Key difference vs. traditional sportsbooks:
| Feature | Prediction Market | Sportsbook |
|---|---|---|
| Market type | Peer-to-peer price discovery | House-set odds |
| Pricing | Market-driven | Fixed odds |
| Outcome settlement | $1 per winning contract | Variable payouts |
| Fee model | Trading fees / spread | Vig (juice) |
This model attracts strategies ranging from probabilistic forecasting to arbitrage and hedging. More details here on Prediction Markets vs. Sports Betting.

Liquidity & Volume Metrics
Liquidity and volume distinguish serious prediction markets. Higher liquidity typically means tighter spreads and faster fills, especially around big events (e.g., Presidential elections or Super Bowl futures).
Approx. trading volume snapshot:
| Platform | Estimated Monthly Volume |
|---|---|
| Polymarket | ~$1.9B+ (sports heavy) |
| Kalshi | $4.4B+ (wide event mix) |
| Robinhood/Underdog | Variable, rising |
These figures show institutional and retail engagement in prediction markets far beyond early niches.
Legal & Regulatory Landscape (U.S.)
Prediction markets have seen high scrutiny and rapid development:
- CFTC regulation: Kalshi’s designation gives it strong oversight.
- Ongoing debates: Some regulators argue these markets operate like gambling.
- Sports betting expansion: Entities like FanDuel partnering with CME Group signal mainstream adoption
This means where and how you can trade may vary by state and platform. Always consult each platform’s legal disclosures.
Event Types You Can Trade
Most prediction markets categorize events into:
- Politics: Elections, primaries, policy outcomes.
- Economics: Inflation, jobs data, Fed decisions.
- Sports: Match winners, futures, MVP markets.
- Culture & media: Award winners, major news outcomes.
- Finance & commodities: Indices and price direction.
This breadth makes them more like financial markets than casual betting apps.
Expert Tips for Choosing an App
1. Liquidity matters: Higher liquidity = tighter pricing and easier trades.
2. Know your event focus: Some apps specialize (e.g., political markets), while others cover broad events.
3. Fees & spreads: Look at transaction costs, higher fees can erode returns.
4. Regulation: U.S. regulated markets often provide better legal clarity.
Transaction Fees:
Prediction market platforms can make their money on transaction fees or by leveraging the bid-ask spread. Fees can be variable based on how much you spend. The platform Kalshi usually charges $0.02 to buy a $0.40 contract and $1.68 to buy 100 $0.40 contracts. Competing platform Polymarket does not charge fees and instead earns on the difference between the bid price and the higher selling price. - YAHOO Finance
