Prediction markets, like Polymarket, offer a fascinating way to bet on future events. To navigate these platforms effectively, understanding the specific terminology is crucial. Whether you're using PolyCopy to follow top traders or practicing in paper mode, this glossary will help you speak the language of prediction markets.
Core Concepts
- Market: An event or question on which users can trade shares. Examples include "Will XYZ Stock Close Above $100 on Friday?" or "Who Will Win the Next Presidential Election?".
- Share/Contract: A tradable unit within a market. Each share represents a potential outcome. For instance, in a "Yes/No" market, you might buy "Yes" shares or "No" shares.
- Outcome: The specific result of a market. If you buy a "Yes" share and the outcome is "Yes," your share will resolve to $1.00.
- Resolution: The process by which a market's outcome is determined and settled. This happens once the event has occurred and the result is verifiable.
- Liquidity: The ease with which shares can be bought or sold without significantly impacting their price. High liquidity means there are many buyers and sellers, making it easier to enter and exit positions.
- Liquidity Provider (LP): A user who provides capital to a market to facilitate trading. LPs earn fees from trades on that market.
- Fees: Charges applied to trades, often a small percentage of the trade value. These fees contribute to the platform's operation and sometimes to liquidity providers.
Trading Mechanics
- Buy/Sell: The fundamental actions in a market. You buy shares if you believe an outcome will occur, and you sell shares if you believe it won't or if you want to close a profitable position.
- Long: To buy shares of an outcome, expecting its price to rise or for it to be the correct outcome.
- Short: In some prediction markets, you can effectively "short" an outcome by selling shares you don't own (expecting to buy them back cheaper) or by buying shares of the opposite outcome.
- Price (of a share): Represents the market's perceived probability of an outcome occurring. A share priced at $0.75 suggests a 75% probability of that outcome. Prices fluctuate based on trading activity.
- Portfolio: Your collection of active and resolved positions across various markets.
- Position: Your current holding (number of shares) in a specific market.
- Profit/Loss (P&L): The financial gain or deficit from your trades. Unrealized P&L refers to open positions, while realized P&L is from closed positions.
Risk & Strategy
- Arbitrage: The practice of simultaneously buying and selling shares in different markets or on different platforms to profit from price discrepancies. While rare and often quickly closed by automated bots, it's a theoretical concept.
- Hedging: Taking a position in a market to offset potential losses from another position or real-world exposure.
- Market Maker: A participant who places both buy and sell orders to profit from the spread between the bid and ask prices, contributing to market liquidity.

FAQ
Q: What does a share price of $0.50 mean?
A: It means the market currently believes there's a 50% chance of that outcome occurring.
Q: How do I make money?
A: You profit by buying shares of an outcome at a lower price and either selling them at a higher price or holding them until resolution if that outcome is correct (where they resolve to $1.00).
Q: Can I lose more than I invest?
A: No, in most prediction markets, your maximum loss on a position is the amount you invested in buying the shares.
