10 Things Every Prediction Market Trader Must Know
- You trade against humans, not the house. There is no built-in structural disadvantage from vigorish — instead, your competitive advantage stems from superior probability assessment relative to other market participants.
- The price IS the probability. When a YES share trades at 0.65, that reflects the collective market view of a 65% likelihood. Your objective: identify 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. Restrict individual trade exposure to no more than 5% of your total trading capital.
- Track your calibration. Without systematic records of your prediction accuracy, you cannot reliably determine whether you possess genuine edge.
- Liquidity matters. Bid-ask spreads that are too wide will erode your profit margins. Prioritise markets offering spreads below 2 cents.
- Update on new information. As fresh developments emerge and shift probability assessments, adjust your holdings accordingly — resist the urge to cling to outdated positions.
- USDC is your currency. Stablecoin settlement eliminates foreign exchange exposure, enables rapid fund transfers, and removes withdrawal friction entirely.
- Start small, scale proven edge. Build familiarity with platform mechanics through modest initial trades before committing larger capital to strategies you've validated.
- Telegram is your platform. PolyGram delivers unmatched prediction market depth and liquidity directly to your mobile device.

- How long until I know if I have edge?
- Between 50 and 100+ completed transactions provides sufficient information to evaluate basic calibration patterns. Anticipate 3-6 months of committed trading activity before you can confidently assess whether you possess genuine edge.
