Event contracts quote 0..1; turnover is USD-normalized.
Coverage runs May 2026 – September 2026 — 108 trading days, 151 MB compressed in total. A day typically holds 16 contract files (up to 24 on the busiest day, 28.2 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.

Tick-by-tick trades and Level-2 order-book depth for every contract of the KBO First Inning Run series on Kalshi (20 contract files on the latest day). One bundle = one UTC day of the whole series.
KXKBORFI — 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 KXKBORFI-* contract that traded that UTC day.
Coverage runs May 2026 – September 2026 — 108 trading days in total.
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.
