Prediction Market Edge Analyzer — Find Which Categories Actu
Example session with this skill installed
Analyze my Polymarket trades in trades.csv to find which categories have a positive edge and where I am losing the most money.
- Read your context and instructions
- Compiled the prediction market edge
I have analyzed 333 settled trades from your CSV. The data shows a clear divergence between your performance in sports markets versus crypto-related event contracts.
Prediction Market Performance Audit
| Category | Trades | Hit Rate | Avg Entry | Break-even | Edge (pp) | Net PnL | Result |
|---|---|---|---|---|---|---|---|
| Sports | 142 | 5.63% | 0.032 | 3.20% | +2.43 | +$412.50 | ✅ Profitable |
| Politics | 88 | 12.50% | 0.115 | 11.50% | +1.00 | +$185.00 | ✅ Profitable |
| Crypto | 65 | 1.54% | 0.028 | 2.80% | -1.26 | -$210.00 | ❌ Bleeding |
| Social | 38 | 0.00% | 0.045 | 4.50% | -4.50 | -$150.20 | ❌ Bleeding |
Odds Bracket Breakdown
| Bracket | Trades | Win Count | Actual Hit Rate | Implied Prob | Edge |
|---|---|---|---|---|---|
| < 2¢ | 45 | 0 | 0.00% | 1.45% | -1.45 |
| 2¢ - 5¢ | 190 | 8 | 4.21% | 3.10% | +1.11 |
| 5¢ - 10¢ | 68 | 5 | 7.35% | 7.80% | -0.45 |
| > 10¢ | 30 | 4 | 13.33% | 12.10% | +1.23 |
Summary Findings:
Your edge is strongest in the
Sports category within the
2¢ - 5¢ range. You are significantly overpaying for "moonshot" crypto bets (sub-2¢) where your realized hit rate is zero against an implied cost of 1.45%.
Next steps
- Stop betting on Crypto markets with entry prices below 5¢; these are currently your largest source of drain.
- Increase size on Sports markets where entry is between 2¢ and 5¢ to capitalize on your +2.43pp edge.
- Export new data after 50 more trades to see if the Social category stabilizes or remains a total loss.

About this skill
The problem
Trading low-probability, high-payout markets feels great when you hit one — but you can't actually tell by hand whether you're profitable overall, or which category is quietly bleeding your bankroll.
The method
This skill applies one clean principle:
Break-even hit rate ≈ your entry price. (Buy at 3¢ → you need >3% hit rate to be profitable.) edge = actual hit rate − average entry price
edge > 0→ that category has positive expectancy, keep itedge < 0→ structural bleed, cut it
Output
A self-contained HTML report plus Markdown summary:
- KPIs — wins, hit rate, total invested, net P&L, ROI
- By category — trades, hit rate, break-even rate, edge (pp), average odds, net P&L, verdict
- By odds band — performance across <2¢ / 2-5¢ / 5-10¢ / 10-20¢ / >20¢ entry ranges
- Conclusion — automatically lists categories with positive expectancy
Sample result (333 real trades)
| Category | Trades | Hit rate | Break-even | Edge | Net P&L | Verdict |
|---|---|---|---|---|---|---|
| Sports events | 60 | 5.0% | 3.0% | +2.0pp | +113 | ✅ Positive |
| Crypto | 149 | 1.3% | 2.7% | −1.4pp | −207 | ❌ Negative |
| Celebrity/social | 78 | 2.6% | 3.0% | −0.4pp | −43 | ❌ Negative |
Insight: inefficiency (and edge) lives in low-liquidity event markets, not in efficiently-priced crypto markets.
