Polymarket — biggest 24h moves
A price that jumped several points means information arrived. The question is whether the book overshot or hasn't finished repricing.

Kalshi — biggest 24h moves
Same idea on the regulated venue. Kalshi's flow is sports- and macro-heavy, so its movers tend to cluster around scheduled events rather than breaking news.

Deepest books on Polymarket
Volume is where you can actually get filled at size. A great edge in a $400 book is a thought experiment, not a trade.

Deepest books on Kalshi
Ranked separately: Kalshi reports volume in contracts, Polymarket in dollars, and the two venues' figures aren't directly comparable. We convert Kalshi's to notional dollars, but the sampling differs — treat these as within-venue rankings.

Near-resolved, still trading
Contracts above 93¢ or below 7¢ that still see volume. This is where longshot bias lives — the last few cents are frequently mispriced in both directions, and fees are at their smallest here.

How to read this page
Every number here is a probability wearing a dollar sign. A contract at 62¢ means the market collectively believes there's a 62% chance — see the field guide for where that breaks down.
The movers tables are the interesting ones. Working out whether a repriced market has gone far enough — in the minutes after the news rather than the hours — is the entire job, and it's what FluxrBot automates.
Before acting on anything here, run the numbers: payout and fees, position size, and if the same event appears on both venues, whether the gap is real.
Data comes from the venues' public APIs and is a snapshot taken at build time, not a live feed — prices move between rebuilds. Coverage is a sample of open markets, not the full universe. Nothing here is a recommendation to trade; see the risk disclosure.
