Tick-by-tick trades and order-book depth for every Kalshi “Big 3 Basketball Game” contract — 54 trading days as downloadable day bundles, €1 per day.
Per-day trade and turnover statistics exist from July 2026 onward; older days are archived without them.
A series-day bundle contains every Big 3 Basketball Game contract that traded on Kalshi on that UTC day — 2 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 June 2026 – August 2026 — 54 trading days, 21.3 MB compressed in total. A day typically holds 6 contract files (up to 8 on the busiest day, 2.98 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 2 largest Big 3 Basketball Game contract files recorded on 2026-08-22 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.
