Why buy sports 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.
Sports prediction-market data — FAQ
What sports prediction-market data can I download?
Tick-by-tick trades and Level-2 order-book depth for every contract of 1,088 sports series on Kalshi & Polymarket — NFL game totals, FIFA World Cup, ATP/ITF tennis matches, MLB games. Each series page lists its exact coverage and day count.
How far back does the sports data go?
Coverage runs May 2025 – present — 126,493 series-days in total across the category.
Is every sports contract included?
Yes — every contract of every listed series, every UTC day since we added the venue, at full order-book depth; nothing is sampled or cut to a top-N. The tables on this page show the largest series, the archive holds all of them.
How is the sports data sold?
As series-day bundles: one purchase covers every contract of a series for one UTC day, €1 — no subscription, no minimum. Pick days in the shop calendar; delivery is per file, one ZIP per day, or a resumable multi-day archive.
Do I need an account or a sales call?
No. Pick the sports 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 sports 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.
What format do the files ship in?
One zstd-compressed text file per contract per UTC day, in the same documented schema as every crypto venue; trades also export as gzipped CSV or Parquet at no extra cost. Free samples are on the downloads page, the schema in the market-data specification.
What was the busiest sports trading day?
2026-09-27 — $97.5M of USD turnover over 1,202,248 trades in a single series-day.
