10 Things Every Prediction Market Trader Must Know
- You trade against humans, not the house. There is no structural disadvantage from vig — your competitive advantage emerges from superior probability estimation relative to other market participants.
- The price IS the probability. When a YES share trades at 0.65, the market is pricing in a 65% likelihood of the outcome occurring. Your task: identify instances where this valuation diverges from reality.
- Focus on your domain. Concentrate your trading activity in markets where your knowledge base outpaces what the broader market has already priced in.
- Size positions with Kelly. Allocate no more than 5% of your total capital to any individual position.
- Track your calibration. Without systematic records of your forecast accuracy, you cannot determine whether you possess genuine edge.
- Liquidity matters. Tight bid-ask spreads preserve your returns. Prioritise markets where spreads remain below 2 cents.
- Update on new information. When fresh developments alter outcome probabilities, adjust your holdings accordingly — resist the temptation to hold positions based on outdated assumptions.
- USDC is your currency. Eliminates foreign exchange exposure, enables rapid settlement, and removes withdrawal friction.
- Start small, scale proven edge. Build familiarity with the mechanics through modest trades before expanding your position sizes.
- Telegram is your platform. PolyGram delivers the globe's most robust prediction market liquidity directly to your mobile device.
