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:

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
