Tick-by-tick trades and order-book depth for every Kalshi “Nobel Physics prize” contract — 119 trading days as downloadable day bundles, €1 per day.
Trades and USD turnover summed over every contract of the series across 30 captured days to 2026-09-09, from the recorded tick data — the per-day averages divide by the captured days. Buy share, quoted spread (in contract price cents, 0..1 = 100 ¢), best-bid/ask depth and Level-2 update counts are turnover-weighted over the same window.
A series-day bundle contains every Nobel Physics prize contract that traded on Kalshi on that UTC day — 24 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 May 2026 – September 2026 — 119 trading days, 13.2 MB compressed in total. A day typically holds 24 contract files (up to 24 on the busiest day, 729 KB). Pick individual days in the shop calendar for €1 each; delivery is an instant per-file download or one archive for the whole day.
