Polymarket whale alerts that don't waste your time
Most whale alerts fire on every big trade. Here's how to filter for the ones with a track record behind them.
Why raw alerts are noisy
A $50k trade is often a hedge, a market maker, or someone closing a position. Size alone doesn't tell you whether the trader is usually right.
Filter by record
Set alerts for wallets with enough graded bets and a positive price-adjusted edge, or for a market you follow. The leaderboard shows the sample size so you can see how much a record is worth.
Filter by price
A whale buying at 97¢ risks a lot to make a little. Bets far from 0¢ or 100¢ carry more information per dollar.
Watch the exits
A position a proven wallet has since sold isn't a live bet any more. Open-bet lists on WhaleGrader mark when a wallet has exited or sold most of a position.
Setting one up
Alert rules on WhaleGrader can follow a wallet, a market, or proven wallets in general, with a minimum size. Delivery by Telegram and email is coming; matches show on the alerts page now.
