Prediction Market Intelligence Engine 🔮 v3.0

Cross-platform prediction market aggregator producing actionable trading signals — not just raw data.

Aggregates Polymarket, Kalshi, Manifold, and PredictIt (US political markets). Runs AI-powered intelligence briefs via DeepSeek.

Why Traders Use This

Existing scrapers dump raw JSON. This Actor gives you signals you can trade on:

Signal	What It Detects	Trader Action
Arbitrage	Same event, different odds (cross-platform)	Risk-free spread capture
Whale Alerts	$10K+ volume on contested markets	Follow the smart money
Volume Anomalies	30%+ of total volume in past 24h	Front-run breaking events
Momentum Leaders	Strongest directional conviction	Trend-following entries
Dead Cat Bounces	Extreme price + sudden volume	Avoid traps / short the bounce
Price Surgers	4%+ move in 1h or 8%+ in 24h	Momentum trading
Expiry Urgency	Markets resolving within 7 days	Last-minute positioning
Risk Rankings	Composite risk score (price + volume + expiry)	Position sizing

What's New in v3.0

• PredictIt — largest US political prediction market added
• Smart filtering — removes dead markets (zero volume/liquidity)
• Risk scoring — composite risk per market (price extremity × volume × expiry)
• Expiry urgency — flag markets resolving this week
• Upgraded AI brief — bolder, more actionable, no hedging
