Install and run

Setup complexity: low.

clawhub skill install s174pq5f3gzez3838vt2642fmx848f1d:polymarket-screener

Setup complexity is classified as HIGH. You must provision dedicated cloud infrastructure or an isolated VM. Do not run this directly on your local workstation.
Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

# Polymarket Screener 🎯

Filter and analyze prediction markets on Polymarket using their public API. Find undervalued bets, track probability movements, and discover high-opportunity markets.

## Comparison: Polymarket Screener vs Manual Browsing

| Capability | Manual Browsing | Polymarket Screener |
|-----------|----------------|-------------------|
| Filter by probability range | ❌ Limited | ✅ Exact range (e.g., 20%-40%) |
| Filter by liquidity | ❌ No | ✅ Min/max liquidity filters |
| Track probability changes | ❌ Manual checking | ✅ Automated tracking with delta |
| Multi-category scan | ❌ One at a time | ✅ All categories at once |
| Probability movement alerts | ❌ No | ✅ Configurable thresholds |
| Historical probability data | ❌ Limited chart | ✅ Exportable time series |
| Bulk opportunity scoring | ❌ No | ✅ Automated scoring |
| Custom watchlists | ❌ No | ✅ JSON watchlist with tracking |
| Export to HTML report | ❌ No | ✅ Professional report output |
| Sort by expected value | ❌ No | ✅ Built-in EV calculator |

## Getting Started

No API key needed — Polymarket's public API is free.

```bash
# List active markets
bash scripts/polymarket-screener.sh list --limit 20

# Filter by category
bash scripts/polymarket-screener.sh list --category politics --limit 50

# Find high-opportunity markets (low probability, high liquidity)
bash scripts/polymarket-screener.sh opportunities --min-liquidity 50000 --prob-range "5-30"

# Track probability changes
bash scripts/polymarket-screener.sh track --market-id MARKET_SLUG --hours 48

# Generate full screening report
bash scripts/polymarket-screener.sh report --output polymarket-report.html
```

## Market Categories

- **politics** — Elections, legislation, government actions
- **crypto** — Price predictions, ETF approvals, protocol events
- **sports** — Game outcomes, championships, player performance
- **entertainment** — Awards, releases, celebrity events
- **science** — Space, climate, research milestones
- **business** — Earnings, IPOs, M&A, market indices
- **world** — Geopolitics, international events

## Opportunity Scoring

Markets are scored based on:

```
Score = (Liquidity Factor × 0.3) + (Probability Edge × 0.3) + (Time Value × 0.2) + (Movement × 0.2)

Liquidity Factor:  Higher liquidity = higher score (easier to enter/exit)
Probability Edge:  Markets with probabilities far from 50% but trending = opportunity
Time Value:        Markets resolving soon with high uncertainty = valuable
Movement:          Recent probability shifts indicate new information
```

### What Makes a Good Opportunity?

1. **Probability between 15-35% or 65-85%** — Enough edge without extreme odds
2. **Liquidit

## Description:

Filter Polymarket prediction markets and track probabilities. Use when screening bets, drafting analyses, outlining trends, tracking price movements.

This skill is ready for commercial/non-commercial use.

## Publisher:

[bytesagain-lab](https://clawhub.ai/user/bytesagain-lab)

### License/Terms of Use:

MIT-0

## Use Case:

External analysts, traders, and developers use this skill to screen Polymarket markets, compare odds, identify possible value bets, and maintain local watchlists for analysis. It provides analysis only and does not place trades or manage positions.

### Deployment Geography for Use:

Global

## Known Risks and Mitigations:

Risk: The package includes an unrelated content-writing command that can retain user prompts or topics in a local history file.

Mitigation: Install only after the publisher removes or clearly documents the unrelated script and explains local data retention controls.

Risk: The documented Polymarket command names and packaged scripts do not fully match, which can lead users to run behavior they did not intend.

Mitigation: Verify the installed entrypoint and command behavior before execution, and require corrected documentation from the publisher.

Risk: Prediction market analysis can be mistaken for betting advice and may involve real-money financial loss.

Mitigation: Treat output as analysis only, do independent research, and apply user-defined position and loss limits outside the skill.

# Polymarket Screener — Tips & Tricks 🎯

## Finding Value Bets

1. **Look for stale markets** — Markets that haven't moved in days despite new information are often mispriced.
2. **Check volume vs liquidity** — High liquidity but low volume means the market is sleepy, opportunity to enter.
3. **Probability extremes** — Markets at 5% or 95% can have huge payoffs but are usually priced correctly.
4. **The 20-40% sweet spot** — Markets in this range often have the best risk/reward for contrarian bets.

## Market Analysis Tips

- Compare Polymarket odds to other prediction markets (Kalshi, Metaculus) — discrepancies signal opportunities
- Follow the "smart money" — sudden large bets shifting probability indicate informed traders
- Check the resolution criteria carefully — many disputes arise from ambiguous resolution rules
- Time decay matters — a 30% market resolving tomorrow is very different from one resolving in 6 months

## Category-Specific Notes

- **Politics** — Most liquid category, hardest to find edge unless you follow polls closely
- **Crypto** — You probably have alpha here if you're in the crypto space
- **Sports** — Efficient markets, hard to beat unless you have specialized knowledge
- **Science/World** — Often mispriced due to lower attention, good for patient bettors

## Watchlist Strategy

- Keep 10-20 markets on your watchlist, not 100
- Set probability change alerts at ±5% for early warning
- Review watchlist weekly and prune resolved/irrelevant markets
- Focus on markets resolving in 7-60 days for best time value

## Risk Management

- ❌ Never bet more than 5% of bankroll on a single market
- ✅ Diversify across categories and timeframes
- ✅ Take profits when a market moves significantly in your favor
- ✅ Keep a trading journal — track WHY you entered each position
- ✅ Set a monthly loss limit and stick to it
