Everything you need to trade the spread

From raw market data to actionable opportunities — in one place.

Real-Time Opportunity Radar

Cross-venue market normalization scans Polymarket and Kalshi every few minutes. Opportunities are ranked by tradable spread and confidence score so you see the best edges first.

High-Confidence Matching Engine

Our matching pipeline compares title, rules, close time, and polarity across venues. Each match gets a confidence score and risk flags so you know exactly what you're trading.

Tradable Spread Estimates

Raw spread minus estimated slippage and fees gives you the tradable spread — the number that actually matters. Sparklines show trend so you can time your entry.

Instant Email Alerts

Set threshold-based alert rules for any category. Get notified by email the moment a high-spread opportunity matches your criteria — before the market corrects.

Watchlist & Detail View

Save your top matches to a watchlist. The detail view shows full spread history, venue comparison, risk flags, and AI-generated explanations for every matched market.

Risk-Flag Review Queue

Low-confidence matches go through a human-in-the-loop review queue. Only clean, validated matches surface to the opportunity dashboard.
