Diversification in prediction markets means spreading risk across outcomes that do not all depend on the same event, while watching for hidden correlation.
What Correlation Means
Two markets are correlated when the same news moves both. Several positions on one election, one team or one economic report can behave like a single large bet.
Spotting Hidden Overlap
Ask what single event could make every position lose at once. If one answer covers most of your portfolio, you are less diversified than it looks.
Limits of Diversification
Spreading money reduces the impact of one surprise, but it does not remove risk. Many small losing positions still add up to a loss.
Worked Example
A trader holds YES in three markets: a candidate winning a primary at 60¢, the same candidate winning the nomination at 40¢, and their party winning a state at 55¢. One poor debate could push all three down together, so the trader treats them as one combined position and trims its total size.
Key Takeaways
- Correlated positions act like one bigger position.
- Ask which single event could sink everything.
- Group related markets when checking your total risk.
- Diversification lowers, but never removes, risk.
