Prices quote 0..1 (probability of Yes). Open/high/low/close/VWAP are that UTC day’s trade prints per contract; the implied outcome reads the last print — ≥ 0.97 as Yes, ≤ 0.03 as No, anything between as still open — venues publish the official result. Buy share = taker-buy side of turnover.
Over the last 1 captured days, the turnover-weighted quoted bid-ask spread was 42.9 ¢ (contracts quote 0..1 = 100 ¢), the mean best-bid/best-ask notional was about $22.52 per side, 100 % of USD turnover was taker-buy. These figures are computed from the recorded Level-2 order books and trade prints — the same data in the day bundles.
KXHEARINGMENTION-26SEP15-TERR — $143.08 USD turnover over 5 trades on Kalshi. The 8 most traded contracts of the series did 18 trades and $307.69 that UTC day. Open, high, low, close and VWAP per contract are listed on this page; the tick-level data is in the day bundle.
