10 Things Every Prediction Market Trader Must Know
- You trade against humans, not the house. Absence of a structural house edge means your advantage stems from superior probability estimation relative to competing traders.
- The price IS the probability. When a YES contract trades at 0.65, that reflects a 65% implied likelihood according to market participants. Your role involves identifying instances where this valuation diverges from reality.
- Focus on your domain. Concentrate your trading activity in markets where your knowledge base surpasses prevailing market sentiment.
- Size positions with Kelly. Allocate no more than 5% of your total capital to any single position.
- Track your calibration. Systematic measurement of your prediction accuracy is essential — without it, you cannot determine whether genuine edge exists.
- Liquidity matters. Tight bid-ask spreads preserve your profits. Prioritise markets displaying spreads narrower than 2 cents.
- Update on new information. Adjust holdings promptly when fresh developments alter probability assessments — resist the cognitive bias toward your initial position.
- USDC is your currency. Denominating in USDC eliminates foreign exchange exposure, enables rapid settlement, and removes withdrawal friction.
- Start small, scale proven edge. Validate your approach through modest initial stakes before expanding capital deployment.
