Direct answer
A Polymarket market scanner is a ranked view of active prediction markets that helps users find meaningful probability moves, liquidity changes, and resolution risks. The best scanner is not a price table; it is a workflow that says which market deserves attention and what to verify next.
How to scan markets
The safest prediction-market workflow separates attention, evidence, source quality, and next action. A probability move can be important, but it is not useful until the market is liquid enough, the rule is clear enough, and the user knows what to verify next.
- Start with active, liquid markets only.
- Rank by 1h and 24h movement after spread and liquidity checks.
- Separate research observations from resolution-risk jobs.
- Open the market detail before acting on the headline probability.
What to verify before trusting the move
Good research tools keep the boring details visible. Expiry, resolution source, official status, spread, liquidity, and related markets often explain why a headline probability should be treated carefully.
- Is the market still active and unresolved?
- Is the spread tight enough for the move to be meaningful?
- Did 24h volume confirm the move?
- Does the resolution rule match the plain-English headline?
How Orrery handles it
Orrery's scanner keeps live-research markets separate from pinned, resolved, and expired rows. It exposes category, liquidity, volume, spread, score, and action labels so the scanner becomes the first step in a research loop.
Orrery is not a broker and does not provide trade recommendations. It ranks research work, explains market structure, and keeps resolution rules visible so humans and agents can make better verification decisions.
FAQ
What should a Polymarket scanner show first?
It should show live markets with meaningful movement, enough liquidity, a readable spread, and a clear next action.
Should resolved markets appear in a scanner?
Not in the default live scanner. They belong in resolution verification or archive views.
Is a scanner a trading signal?
No. A scanner ranks what to inspect. It does not recommend buying or selling.
