Prediction Market Scanner
Surface the markets that are actually doing something — ranked, explained and auditable.
The scanner reads the entire market universe on every refresh and ranks what stands out: sharp moves, unusual volume, wide spreads, liquidity shifts, markets near expiry with probability still far from resolution. Each row carries a plain-language reason and the numbers behind it, so a rank is a claim you can check, not a black box.
Under the hood
- 01
Score the whole universe
Deterministic rules run over every tradeable market on each refresh, assigning a 0–100 rank for each opportunity type — no sampling, no watchlist required.
- 02
Classify what stands out
Large move, unusual volume, wide spread, liquidity shift, high volatility, new market, expiring soon — each a distinct signal with its own thresholds.
- 03
Show the evidence
Every ranked row states why it ranked and lists the structured metrics — the move size, the volume ratio, the spread — that produced the score.
What you get from it
Find the story, not the noise
The board tells you what exists; the scanner tells you what changed. It is the difference between watching a market and being told to look.
A rank you can defend
Because the score is rule-derived and the inputs are shown, you can reconstruct any ranking by hand — and dismiss the ones that do not survive it.
Filter to your themes
Narrow by category and minimum score so the scan reflects the markets you actually trade.
