Trades and USD turnover summed over every contract of the series across 5 captured days to 2026-08-31, from the recorded tick data — the per-day averages divide by the captured days.

A series-day bundle contains every 1st Half Winner contract that traded on Kalshi on that UTC day — 6 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.
