Kalshi KXFIGHTMENTION — Fight Historical Data

Fight 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 Fight contract that was listed on Kalshi on that UTC day — traded or not — 84 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 March 2026 – July 2026 — 83 trading days, 626 MB compressed in total. A day typically holds 80 contract files (up to 199 on the busiest day, 73.3 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 Fight model on this data
Every resolved Fight contract is a labelled example — a count, a score, a date or a name — and the day bundle holds its full order-book path and trade tape, nanosecond-stamped. The statistics on this page cover the most traded contracts per day; the bundle holds every contract listed on Kalshi that day.
Split by time, never at random — adjacent contracts share a regime, and a random split leaks it into the test set. The training-data hub covers labels, leakage and walk-forward validation.
Purchased data is for your own use — backtesting, research, analytics and training your own models, in-house or in your own products; the trained models and derived data you build from it are yours. The raw files and tick streams themselves may not be redistributed, resold or published. The full terms are on the data license page.
Why buy Kalshi Fight 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.

Kalshi Fight data — FAQ
What Kalshi Fight data can I download?
Tick-by-tick trades and Level-2 order-book depth for every contract of the Fight series on Kalshi (84 contract files on the latest day). One bundle = one UTC day of the whole series.
What is the Kalshi series ticker for Fight?
KXFIGHTMENTION — every contract of the series carries this prefix in its ticker (followed by the event date and strike). Files in a day bundle are named by the full contract ticker, so a bundle holds every KXFIGHTMENTION-* contract listed that UTC day.
How far back does the Fight data go?
Coverage runs March 2026 – July 2026 — 83 trading days in total.
What format are the Kalshi files in?
One zstd-compressed text file per contract per UTC day, in the same normalized schema as our crypto venues — see the market-data specification; free samples on the downloads page.
Can I get Kalshi Fight 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 records 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 Kalshi Fight historical data cost?
€1 per series-day bundle — every contract of the series for that day — no subscription, no minimum order; buy as a guest in the Data Shop and download immediately. Credit packs lower the effective price and never expire.
Do I need an account or a sales call?
No. Pick the Fight 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 Kalshi Fight 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 was the busiest Fight trading day on Kalshi?
2026-07-25, with $134.6K of USD turnover over 10,310 trades across every Fight contract of the day; the busiest full month was Jul 2026 at $275.4K. Since our statistics began on 2026-07-18 the series has recorded 24,000 trades and $275.4K over 4 captured days. Any of these days is a downloadable bundle.
