Polymarket market scanners

Use a scanner to narrow a watchlist instead of reviewing every market manually. Compare the activity, liquidity or research inputs that make a result appear.

How to choose market scanners

Treat a result as a research candidate

Open the underlying contract and current order book before acting. Screening identifies something to examine; the result does not replace the question’s rules or executable prices.

Inspect the screening process

  • Compare the inputs and filters used.
  • Check how recently the results were refreshed.
  • Look for a path back to original evidence.
  • Choose alerts separately when you need results delivered.
