Prediction markets are platforms where you can trade what are called event contracts— essentially bets on the outcome of a future event.
These contracts typically have a simple yes/no structure. For example:
“Will candidate X win the election?” or “Will inflation exceed 2.5% this month?”
If you believe the event will occur, you buy the “Yes” contract. If you think it won’t, you buy the “No” contract.
The price of a contract — between $0.01 and $0.99 — reflects the market’s current consensus probability of that event happening. A contract priced at $0.60 implies a 60% chance of that outcome.
Once the event settles, the contract resolves. If the outcome occurs, you get $1 per contract. If it doesn’t, the contract expires worthless.
Because the contract prices move as new information becomes available (polls, news, analysis, on-the-ground updates), prediction markets serve two roles:
Speculation and investing. Traders can attempt to profit from correctly anticipating how events unfold.
Information aggregation. The market price aggregates the opinions and information of all participants, often offering a real-time “probability consensus” of what might happen.
Bottom line
Prediction markets have expanded rapidly, and traders now have more choices than ever — from multi-asset brokers to dedicated exchanges built solely for forecasting real-world outcomes. Some offer broad market selection, others emphasize low, transparent fees or deep toolsets for active traders.
The right place to trade event contracts ultimately depends on what you value most — market variety, cost or usability. As the industry continues to grow and more brokers enter the space, expect even greater competition, better tools and more ways to trade on real-world events.
