Democratic state legislative supermajorities, tick by tick.
Kalshi series KXDEMSTATESUPERMAJ: order book and trades, 2026-10-01 → 2026-10-23.

The order-book and trade history of Kalshi's Democratic state legislative supermajorities series (a one-off event): top of book on every change, the 25-level book on every change in YES terms, every trade with the taker's side, and Kalshi's own ticker, with exchange timestamps to the millisecond. Captured by us from Kalshi's websocket on two independent legs and checked against the exchange's own book snapshots.

What a KXDEMSTATESUPERMAJ day contains

Four parquet files per day, every market of the series in each. Sizes are this series' own averages over its 23 days on disk.

Top of book (every change)kalshi_l1

Best YES bid and ask with sizes and the spread, one row whenever either changed, derived tick by tick from the rebuilt book: not Kalshi's conflated ticker.

~97 kB per KXDEMSTATESUPERMAJ day
Order book, 25 levels, every changekalshi_l2

The whole ladder after every book event, in YES terms (the NO bids become the asks, at their sizes), 25 levels a side: wide columns bid_px_1 … ask_sz_25, plus the exchange's own hourly snapshots. Each row is self-contained, so you can start reading mid-day.

~714 kB per KXDEMSTATESUPERMAJ day
Tradeskalshi_trades

Every trade: YES and NO price, size in contracts, the taker's side, block-trade flag, trade id.

~4 kB per KXDEMSTATESUPERMAJ day
Kalshi ticker (~1 s)kalshi_ticker

Kalshi's own ticker feed, about one update a second per market: last price, YES bid/ask with sizes, cumulative volume and open interest in contracts and dollars.
