Prices quote 0..1 (probability of Yes). Open/high/low/close/VWAP are that UTC day’s trade prints per contract; the implied outcome reads the last print — ≥ 0.97 as Yes, ≤ 0.03 as No, anything between as still open — venues publish the official result. Buy share = taker-buy side of turnover; spread = the contract's turnover-weighted quoted bid-ask spread in cents, top-1 depth = mean best-bid/ask notional per side, L2 updates = order-book level updates recorded for the contract that day. “Settles” is the venue-listed close time of the contract where the venue publishes one (UTC).

How a AK primary contract trades
On Kalshi, a AK primary contract trades for about 204 days from open to close, is listed roughly 221 days before it opens, and quotes in 0.1 ¢ price steps (0..1). Measured on the 8 contracts captured on 2026-09-01.
Build a AK primary model on this data
Every resolved AK primary contract is a labelled example that trades for weeks or months, not minutes: the label is the race outcome, the margin bucket or the nominee, and the signal in between is mostly the order book — quotes move on news while trades stay sparse. The day bundle holds each contract's full Level-2 book path and every trade of that UTC day, 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 election cycle and by race, never at random — months of quotes on one contract are one regime, and a random split leaks the result backwards; validate across races and cycles, not within one. The election-markets guide works thin books, book updates as the main signal and calibration over months through.
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.

Why buy Kalshi AK primary 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.

Kalshi AK primary data — FAQ
What Kalshi AK primary data can I download?
Tick-by-tick trades and Level-2 order-book depth for every contract of the AK primary series on Kalshi (12 contract files on the latest day). One bundle = one UTC day of the whole series.
What is the Kalshi series ticker for AK primary?
KXGOVAKPRIMARY — 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 KXGOVAKPRIMARY-* contract listed that UTC day.

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 AK primary 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 is the Kalshi AK primary 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.
