The Momentum Machine

The oldest argument at every trading desk: a market just moved, do you chase it or fade it? Everyone has a story. Nobody has data, because answering it requires recorded price paths joined to settled outcomes, and nobody records Kalshi’s. We do. This page pairs every settled market’s day-before price with its two-days-before price, classifies the move, and measures what actually settled.

A “move” is a change of 8¢ or more in that 24-hour window; “steady” markets are the baseline each zone is judged against. Updated hourly as new settlements are harvested.

Strongest measured pattern
Markets at 61–80¢ that had just risen 8¢+ settled YES 71.5%, vs 77.4% for steady ones.
A 5.9-point gap (762 movers vs 1,303 steady), which means recent rises in that zone have, so far, given back their move by settlement more often than not. Source: contracttax.com/momentum

Methodology, honestly

For every settled yes/no market, we take our recorded price nearest 24 hours before the event (within a 2-to-48-hour window) and nearest 48 hours before (within a 26-to-72-hour window), classify the difference as a rise (+8¢ or more), a fall (−8¢ or more), or steady, and compare settlement rates against the steady baseline in the same price zone. Cells report only at 40+ samples; verdicts require a 4-point gap before claiming anything.

Known limits, stated plainly: our snapshots cover markets that entered our scanner’s pool, which skews toward active, liquid markets; sparse paths can register as steady; and the anchor prices are observations, not tradable quotes, so gaps here are evidence about market behavior, not guaranteed executable edges. Fees are not included in these rates. Companion pages: the Truth Machine measures what standing prices mean; this machine measures what changing prices mean. Not financial advice.
