Why buy Esports prediction-market 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.

Esports prediction-market data — FAQ
Does Kalshi have esports markets?
Yes — League of Legends game and map winners, Counter-Strike 2 games, map winners and qualifiers, and Valorant map winners. Polymarket League of Legends, CS2, Dota 2 and Valorant matches each form a family (Polymarket LoL and CS2 are among its most-traded sports families); predict.fun lists the same four titles.
Which esports titles have their own hub?
League of Legends, Counter-Strike 2, Dota 2 and Valorant — each with its own series list, statistics and FAQ; this hub keeps every esports family in one place.
How is esports prediction-market data sold?
One purchase covers every contract of the series for one UTC day — every trade print and the complete Level-2 book per contract, captured co-located with nanosecond timestamps — €1 per series-day, bought as a guest with instant download.
How far back does the Esports data go?
Coverage runs June 2025 – present — 5,033 series-days across 35 series on Kalshi & OG.com & Polymarket & predict.fun. Each series page lists its exact span.
Can I get Esports prediction-market data as CSV or Parquet?
Yes — trades export as gzipped CSV or Parquet at no extra cost, with integer microsecond UTC timestamps that load straight into pandas, polars or DuckDB. Kalshi, OG.com, Polymarket and predict.fun record full order-book depth without a separate BBO stream, so book data ships in the native tick file — the free reader script converts it locally. See the formats overview.
How much does Esports prediction-market data cost?
€1 per series-day bundle — every contract of the series for that UTC day — no subscription, no minimum order. Pick days in the shop calendar, pay as a guest, download immediately.
Do I need an account or a sales call?
No. Pick the Esports series-days in the Data Shop, pay by card as a guest and download immediately — no subscription, no minimum order, no KYC, no enterprise contract, no sales call. Coding agents buy the same bundles through the MCP server.
How is the Esports data captured?
Co-located at the venue, message by message: every Level-2 update and every trade print carries the exchange timestamp and our receive timestamp in integer nanoseconds, an event-id chain makes any gap visible, and one normalized schema across 35+ venues means a parser written for Binance reads these files unchanged. It is the same capture our own high-frequency trading engine runs on — nothing sampled, no top-N cut.
Which market types are in the Esports data?
As of 2026-11-03 the 35 Esports series with a market-type snapshot had listed 435,403 contracts: total / over-under 156,269 · map / game winner 128,634 · spread / handicap 58,549 · moneyline / winner 55,030 · player & team props 31,906 · strike ladder 525 — counted from every contract file of each family across Kalshi, OG.com, Polymarket, predict.fun. Kalshi splits these into separate series; Polymarket, predict.fun and OG.com list one family per league. Each series page shows its own mix.
What was the busiest Esports trading day?
