Fills
Start with the biggest prints
The tool reads Kalshi’s live trade feed and lists the largest recent fills. Set a minimum size. Keep YES, NO, or both. Parlay markets stay out unless you ask for them, because that size comes from the structure.
The tape
Large fills. Then the repeat.
The Kalshi Whale Tracker is the live list. This page is how to read it without treating size as skill.
Flow
Then look for accumulation
Flows group the same market and side and rank them by notional, with the volume-weighted average price. That is where the size went in, not just that a single print existed.
Stop
The row has no name
You see the market, the side, and the size. You do not see the account. The fill can be an entry, an exit, or a hedge. The tracker says it directly: size is not an edge.

Price the leftover
The desk turns a contract price into cents at risk and cents you can make. It does not call a side.
