Per-day trade and turnover statistics exist from July 2026 onward; older days are archived without them.
A series-day bundle contains every Counties won in primaries contract that traded on Kalshi on that UTC day — 8 contract files on the latest covered day.

Event contracts quote 0..1; turnover is USD-normalized.
Coverage runs April 2026 – August 2026 — 131 trading days, 32.5 MB compressed in total. A day typically holds 18 contract files (up to 36 on the busiest day, 7.28 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.

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.
