Prediction Markets: How to Profit From Global Events
Prediction markets let you bet on elections, sports, economic data, and crypto prices using on-chain smart contracts.
Prediction markets are one of the most fascinating applications in all of DeFi. They let you take financial positions on almost any real-world event: who wins an election, whether inflation rises, whether a specific crypto price reaches a target.
Why Prediction Markets Are More Accurate Than Polls
When real money is at stake, people think carefully. The aggregated prediction of thousands of informed participants — each risking their own capital — consistently outperforms expert polls and traditional forecasting.
How They Work On-Chain
A smart contract creates a market on a question. Two outcome tokens are issued: YES and NO, each trading between $0 and $1. If YES is trading at $0.65, the market implies a 65% probability of the event occurring.
