Trading Blind on Polymarket?

The biggest edge in prediction markets is knowing what smart money is doing. Without it, you are at a disadvantage.

Whale Moves Hidden

Big money enters positions quietly. By the time the market moves, you have already missed the signal.

Too Many Markets

Hundreds of active markets across politics, crypto, sports, and more. You cannot manually watch them all for large trades.

No Smart Money Feed

Polymarket does not show you who is trading big. You are flying blind without whale data.
