Your edge in prediction markets comes from finding mispricings. When market prices don't reflect true probabilities. When the crowd is wrong. Here's how to find them systematically.
What creates mispricings
Mispricings happen when market prices diverge from true probabilities. Several forces create this divergence.
Crowd bias
Markets reflect crowd sentiment. Not truth. Political markets overprice popular candidates. Sports markets overprice favorites. The crowd is often wrong.
Information asymmetry
You know something the market doesn't. You read the rules. You understand the settlement mechanism. You have better data. This creates edge.
Low liquidity
Thin markets have wider spreads. Less efficient pricing. Small order flow moves prices more. Creates temporary mispricings.
Market structure failures
Markets don't read their own rules. Classification errors. Settlement edge cases. When markets misunderstand how they resolve, prices are wrong.
Systematic approaches to finding mispricings
Don't rely on intuition. Use systematic methods. Here are proven approaches.
Read the rules
Markets often misprice because traders don't read settlement rules. You read them. You understand edge cases. You find mispricings.
Example: A market says "Will X happen by date Y?" But the rules say it resolves based on a specific data source. The market prices based on intuition. You price based on the data source. Edge.
Compare to reference markets
Compare prices across platforms. Compare to related markets. If prices diverge significantly, one is wrong.
Example: "Biden wins" trades at 60¢ on Kalshi. 55¢ on Polymarket. Same event. Different prices. One is mispriced. Or both. Find which.
Look for structural biases
Markets have systematic biases. Political markets favor incumbents. Sports markets favor favorites. Find these biases. Bet against them.
Example: Markets consistently overprice popular candidates early. Then correct closer to election. Buy unpopular candidates early. Sell before election.
Find low-liquidity markets
Thin markets price inefficiently. Small order flow moves prices. Creates mispricings. But harder to execute.
Example: A market has $100 volume. You can move the price significantly. But you can't size large. Tradeoff.
Red flags markets are wrong
Certain patterns indicate mispricings. Watch for these.
- Prices don't sum to $1.00 (YES + NO ≠ $1.00) - arbitrage opportunity or mispricing
- Related markets have inconsistent prices - one is wrong
- Market price diverges significantly from polls/data - crowd bias
- Low volume but high conviction - inefficient pricing
- Market rules are ambiguous or misunderstood - structural mispricing
- Prices move sharply on small orders - thin market, temporary mispricing
- Cross-platform prices diverge significantly - one platform is wrong
Practical example: finding a mispricing
Scenario: RANKLIST market
Market: "Will the new pope be ranked higher than Trump in RANKLIST by end of 2024?"
Market price: 30¢ (30% probability). You read the rules. RANKLIST uses Google Trends data. Pope is a major religious figure. Trump is a major political figure. Both get high search volume. But pope searches are more consistent. Less volatile.
You analyze historical Google Trends data. Pope consistently ranks higher than most political figures. Including Trump. Your estimate: 80% probability pope ranks higher.
Market price: 30¢. Your estimate: 80¢. Mispricing. You buy at 30¢. Edge: 50¢ per contract.
Why was the market wrong? Crowd didn't read the rules. Didn't understand RANKLIST uses Google Trends. Priced based on intuition. Not data.

Conclusion
Your edge in prediction markets comes from finding mispricings. When market prices don't reflect true probabilities. When the crowd is wrong.
Mispricings come from crowd bias. Information asymmetry. Low liquidity. Market structure failures. Use systematic approaches. Read the rules. Compare to reference markets. Look for structural biases. Find low-liquidity markets.
Watch for red flags. Prices don't sum to $1.00. Related markets have inconsistent prices. Market price diverges from data. Low volume but high conviction. When you find these, investigate. You might have found a mispricing.
