Event contracts quote 0..1; turnover is USD-normalized.

Tick-by-tick trades and Level-2 order-book depth for every contract of the KBO Spread series on Kalshi (52 contract files on the latest day). One bundle = one UTC day of the whole series.
KXKBOSPREAD — 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 KXKBOSPREAD-* contract that traded that UTC day.
Coverage runs May 2026 – September 2026 — 113 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.
