Kalshi Biggest Movers

Which Kalshi markets are repricing right now? This reads Kalshi's live feed and ranks markets by how far the current mid has moved from its previous quote — but it gates on spread and volume first, because most "biggest mover" lists are just thin books breathing. The spread column is your real-vs-noise tell.

How "repricing" is measured

Every market on Kalshi has a current best bid and ask for the YES contract. The midpoint of those is the market's implied probability in cents. This tool compares that current mid to the previous quote Kalshi reports for the same market and calls the difference the move. A market that went from a 51¢ mid to 61¢ shows ▲ +10¢; one that fell to 45¢ shows ▼ −6¢.

Why the spread gate matters. A market quoting 5¢ bid / 95¢ ask has a "mid" of 50¢, but that number is fiction — there is no real two-sided price on a book that wide. A mid "move" there reflects the book breathing, not information arriving. The default keeps spreads tight so the headline list is genuine movement. Loosen it and you will see more rows, and more noise. This is the same lesson in our deep dive on why most Kalshi "signals" are noise.

Frequently asked questions

What counts as a "mover"?
The current mid (average of best yes-bid and yes-ask) versus the previous quote. It's a price delta in cents — what changed, not why, and not whether it holds.

Why gate on spread and volume?
On a wide, thin book the mid is barely meaningful, so a "move" there is an illusion. Tight-spread, min-volume filtering keeps the list to markets where a quote actually means something.

Can I trade straight off this?
No — these are candidates to investigate, not edges to execute. A real move still has to clear fees, have depth to fill your size, and survive the seconds it takes to react. Most raw spikes fade.
