PolyEdge is a quantitative edge detection app for Polymarket prediction markets. Our proprietary algorithm scans 200+ markets to identify mispriced opportunities with high profit potential. How It Works Our algorithm analyzes prediction markets to find where the current price doesn't reflect the true probability. When we detect a mispricing, that's your edge—the potential profit if the market corrects. Edge Types We Detect • Convergence - Markets near resolution at extreme probabilities tend to stay there. ~93% historical accuracy. • Momentum Breakout - Strong directional moves with volume confirmation often continue. ~76% accuracy. • Liquidity Gap - Under-traded markets with strong conviction often have larger mispricings. ~82% accuracy. • News Lag - Markets that moved big recently may still be under-reacting to new information. ~74% accuracy. What You Get • Expected Profit - Potential return if the prediction is correct • Edge Amount - The mispricing between fair value and current price • Confidence Score - How many factors align for this signal • Historical Accuracy - Track record for each signal type • Mini price charts showing recent market movement Pro Features • Auto-refresh every 2 minutes • Background refresh when returning to app • New signal alerts when opportunities appear • Unlimited signals (free users see top 3) • Full access to all detected edges Watchlist Save markets you want to track and monitor their progress over time. Market Details Tap any signal to view full price history, detailed stats, and analysis. Built for traders who want a data-driven approach to prediction markets.
