Tick-by-tick trades and order-book depth for every Kalshi “ATP Set Spread” contract — 4 trading days as downloadable day bundles, €1 per day.
Trades and USD turnover summed over every contract of the series across 3 captured days to 2026-09-02, from the recorded tick data — the per-day averages divide by the captured days.
A series-day bundle contains every ATP Set Spread contract that traded on Kalshi on that UTC day — 74 contract files on the latest covered day. Each file carries the full raw feed: every trade print with price, size and side, plus Level-2 order-book updates, in the same zstd-compressed schema as our crypto venues. Event contracts quote 0..1; turnover is USD-normalized.
Coverage runs August 2026 – September 2026 — 4 trading days, 101 MB compressed in total. A day typically holds 96 contract files (up to 108 on the busiest day, 50.2 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.

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.
