What is Event Trading?
Event trading is trading contracts whose value depends on real-world event outcomes. Traders buy and sell "YES" or "NO" positions, profiting from accurate predictions.
Definition
Event trading (also called outcome trading) is trading contracts linked to event results. YES contracts are worth $1 if the event occurs, $0 if not. NO contracts have opposite values.
For example, a "Will Candidate X win?" contract might trade at $0.65. This price indicates the market assesses 65% win probability.
Event trading differs from traditional betting through exchange mechanics: you trade with other participants, can sell positions before event resolution at any time to lock in gains or cut losses.
How Event Trading Works
- 1Event Selection — Find an event with clear binary outcome (happens or doesn't).
- 2Price Analysis — Current price reflects probability. If you assess higher probability than market, buy YES. Lower? Buy NO.
- 3Position Opening — Purchase YES or NO contracts at current market price.
- 4Position Management — Sell before event resolution to lock profits/losses or hold to expiration.
- 5Settlement — Post-event, contracts resolve: YES = $1, NO = $0. Winning positions pay automatically.
Event Trading Example
Event: "Will the Federal Reserve cut rates in June 2026?"
Current YES price: 40% (market assesses 40% probability)
Your Analysis: Based on macroeconomic data, you assess 70% probability.
Action: Invest $100 in YES contracts.
Outcome: If rates cut—receive $140. Profit = $40. If rates don't cut—lose $100.
