Hey PH! I'm Mei Lin, the builder behind EdgeMarket. I got into prediction markets last year and quickly realized something: the real alpha isn't in the odds — it's in watching what the biggest wallets are doing. When someone drops $500K on a single position, they usually know something. Problem was, there was no easy way to track this. You'd have to manually scan blockchain explorers and piece together wallet activity yourself. Hours of work for a single insight. So I built EdgeMarket. It monitors every Polymarket trade in real-time, classifies wallets (whales, sharks, fish), scores them by win rate, and sends you instant alerts when big money moves. The free tier gives you a delayed feed to explore. Pro unlocks real-time alerts and full analytics. Curious to hear: do you trade on prediction markets? What signals matter most to you?
