Tick-by-tick trades and order-book depth for every Kalshi “A100 Monthly” contract — 77 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 2026-09-15, 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 A100 Monthly contract that traded on Kalshi on that UTC day — 87 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.
