How to download prediction-market data
Step-by-step walkthroughs: what the venues publish, what the archive adds, bulk download, CSV/Parquet and backtesting notes.
Why buy Kalshi, Polymarket, predict.fun & OG.com 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 free full-day samples from the major venues let you test 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.

Prediction-market historical data — FAQ
What prediction-market historical data can I download?
Tick-by-tick trades and Level-2 order-book depth for Kalshi, Polymarket, predict.fun and OG.com event contracts — the same raw feed capture and normalized schema as our crypto archive. Data is sold as series-day bundles: one purchase covers every contract of a series (e.g. all BTC Up/Down 15m markets) for one UTC day.
How is Kalshi, Polymarket, predict.fun and OG.com data captured?
Co-located next to the venues’ infrastructure by the same recording stack that feeds our high-frequency trading engine — every order-book update and every trade print of every contract, with the exchange timestamp and our receive timestamp in nanoseconds and an event-id chain that makes any gap visible. Nothing sampled, no top-N cut.
How much does prediction-market data cost?
€1 per series-day bundle — one day of an entire series family across all its contracts — no subscription, no minimum order. Credit packs lower the effective price and never expire; see pricing.
Do I need an account or a sales call?
No. Pick the 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.
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 — a parser written for Binance data reads Kalshi files unchanged. Free samples are on the downloads page, the schema in the market-data specification.
Can I get Kalshi, Polymarket, predict.fun and OG.com 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. All venues 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.
Can I explore the markets before buying?
Yes — the free analytics render Kalshi, Polymarket, predict.fun and OG.com live (movers, per-venue coverage, per-contract charts), and every series page lists its coverage span and file counts.
How much do Kalshi, Polymarket, predict.fun and OG.com trade per day?
This hub shows whole-venue trades, USD turnover and active contracts per UTC day for every venue, computed from every trade print in our own capture rather than venue-reported volume; the leaderboard ranks series by 30-day turnover and every series page breaks its own days down to the single contract — open, high, low, close, VWAP, trades, turnover and the outcome implied by the last print.
Is there a free sample of prediction-market data?
Yes — every series page offers one free contract file (the busiest contract of a settled day) as the native tick file, as CSV/Parquet export and as a browser order-book replay, plus the curated samples on the downloads page. No account is needed.
Is there a real-time prediction-market data API?
Yes — the same Kalshi and Polymarket feeds stream live over WebSocket (JSON or SBE), captured at each venue and delivered at our Tokyo endpoint over dedicated lines (Kalshi from Ohio at Tokyo; Polymarket from London at Tokyo), and at source where the venue is captured (Kalshi at Ohio; Polymarket at London): the full order book and every trade of every contract, bought as a whole market by the UTC day (€99 per market-day, whole market only) with one API key — no subscription, nothing renews. See Kalshi real-time market data, Polymarket real-time market data, the real-time crypto market data hub and the connection guide.
How much do Kalshi, Polymarket, predict.fun and OG.com trade per day?
Kalshi: about 13.1M trades and $492.2M of USD turnover per UTC day; Polymarket: about 1.3M trades and $78.5M of USD turnover per UTC day; predict.fun: about 583.6K trades and $9.3M of USD turnover per UTC day — averages over the 30 captured days to 2026-11-07, summed from every trade print of every contract in our own capture, not venue-reported volume.
Which prediction-market category has the most trading volume?
Sports — $9.9B of USD turnover, 59 % of all series with statistics in the 30 days to 2026-11-07. The category league table on this page ranks every category; each category hub ranks its series.
What is the biggest prediction-market trading day in the archive?
The busiest single series-day since our statistics began on 2026-07-08 was 2026-11-06 with $178.6M of USD turnover over 4,320,219 trades in one series; the single biggest contract was KXNFLGAME-26OCT12BUFLAR-BUF on 2026-10-13 at $23.2M. In total 1,195,504,618 trades and $48.7B across 2,439 series are in the statistics.
