CS2 Tournament Winner on Kalshi — activity
Per-day trade and turnover statistics exist from July 2026 onward — a limit of the statistics, not of the capture: older days are archived in full (every contract, every message) without a statistics row.
One purchase, the whole series for a day
A series-day bundle contains every CS2 Tournament Winner contract that was listed on Kalshi on that UTC day — traded or not — 8 contract files on the latest covered day. Each file carries the full raw feed: every trade print with price, size and side, plus Level-2 order-book updates, in the same zstd-compressed schema as our crypto venues. Event contracts quote 0..1; turnover is USD-normalized.
Coverage runs April 2026 – September 2026 — 128 trading days, 316 MB compressed in total. A day typically holds 24 contract files (up to 56 on the busiest day, 16.4 MB). Pick individual days in the shop calendar for €1 each; delivery is an instant per-file download or one archive for the whole day.

Build a CS2 Tournament Winner model on this data
Every settled CS2 Tournament Winner 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. The esports guide works map-level labels and the series structure through.

Why buy Kalshi CS2 Tournament Winner data here
Four things every page on this site is built on — and the reason the numbers above exist at all.
We record everything
The complete public feed of each venue as it was published: every Level-2 snapshot and update at the venue's full book depth, every trade with its aggressor side, every quote, funding, mark-price and liquidation event — for every instrument the venue lists, every UTC day since we added the venue. Nothing sampled, no top-N cut, no on-demand capture.
Institutional grade
Captured co-located at the venue with the exchange timestamp and our receive timestamp in integer nanoseconds, an event-id chain that makes any gap visible, and one normalized schema across 35+ venues — the same capture our own high-frequency trading engine and enterprise feeds run on.
€1 per instrument-day
Any instrument-day is €1, series-day bundles start at €1 — no subscription, no minimum order, no tiers to unlock. Credit packs lower the effective price and never expire, and every venue has free full-day samples to test against first.
Self-service for everyone
Pick the days in the Data Shop, pay by card as a guest and download immediately — no sales call, no enterprise contract, no KYC. Coding agents buy the same files through the MCP server, and the free Agent Skill teaches them the format.
