Event contracts quote 0..1; turnover is USD-normalized.
Coverage runs March 2026 – September 2026 — 183 trading days, 35.4 MB compressed in total. A day typically holds 16 contract files (up to 16 on the busiest day, 1.38 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.
Files, size and — where our daily statistics exist — trades and USD turnover per UTC day. “—” means the day predates the statistics capture, not zero activity.
The 16 largest SEC Champion contract files recorded on 2026-09-02 with that day’s trades, USD turnover and last price per contract— every contract of the series is inside that day's bundle; single contracts can also be bought as individual day files.

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.
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.
€1 per series-day bundle — every contract of the series for that day, with invoice on checkout. Buy it in the Data Shop.
