### **About Prediction Markets**

A **prediction market** acts as a decentralized mechanism to aggregate dispersed information, allowing participants to trade contracts whose values depend on the outcomes of uncertain future events. In blockchain-based environments, these markets convert collective beliefs into market prices that closely reflect real world probabilities while ensuring transparency, auditability, and automated enforcement through smart contracts (*The Rise of Blockchain-Based Prediction Markets*, 2024). Recent theoretical research highlights advancements in decentralized prediction system design, particularly through automated market maker (AMM) models that enhance liquidity, mitigate slippage, and reduce vulnerability to front-running (Wang, 2023).&#x20;

Within the decentralized finance (DeFi) ecosystem, three key actions define the market lifecycle - definitions are provided below.&#x20;

### **Definitions**

<table><thead><tr><th width="196.0390625">Job Offering Type</th><th width="187.97265625">Term</th><th>Description</th></tr></thead><tbody><tr><td>Create Market</td><td>Create Market</td><td>Setting up a new prediction market by defining the event, outcomes, resolution criteria, and end date. </td></tr><tr><td>Place Bet</td><td>Place Bet</td><td>Buying a position (shares/contracts) on a specific outcome in a prediction market. You pay the current market price for shares that will be worth $(bet amount) if your prediction is correct, or $0 if wrong.</td></tr><tr><td>Close Position</td><td>Sell</td><td>Closing or transferring your position before the event resolves; locks in profit or loss</td></tr><tr><td></td><td>Terminate</td><td>Ending your exposure before settlement, either by selling, exiting, or platform action. (Given that this is uncommon, it is not mentioned in the article for now)</td></tr><tr><td></td><td>Settle</td><td>Final contract payout when the event is officially resolved; profits/losses are locked in</td></tr></tbody></table>
