## Market types

- Kalshi lists each market type as its own series — 5 CS2 series, 44,373 contracts listed as of 2026-10-22: map / game winner 23,506 · moneyline / winner 14,522 · total / over-under 5,897 · strike ladder 140 · other 308.

## Training data

- Every settled CS2 Spread contract is a labelled example — a match, map or game winner, a map handicap or a kill total — and a best-of series yields one label per map plus one for the series. The day bundle holds each contract's full order-book path and trade tape, nanosecond-stamped, through every map; the statistics on this page cover the most traded contracts per day; the bundle holds every contract listed on Kalshi that day.
- Split by tournament and series, never at random — the maps of one best-of share form and draft, so a random split leaks the series result backwards; walk forward over events. Guide: https://cryptostruct.com/guides/esports-match-markets-data · Hub: https://cryptostruct.com/training-data
