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; spread = the contract's turnover-weighted quoted bid-ask spread in cents, top-1 depth = mean best-bid/ask notional per side, L2 updates = order-book level updates recorded for the contract that day. “Settles” is the venue-listed close time of the contract where the venue publishes one (UTC).

Build a B200 Monthly model on this data

Every B200 Monthly event lists a ladder of strikes — one contract per range — and the rung that settles in the money is the label, so the ladder's prices read as an implied distribution rather than one probability. The day bundle holds the full order-book path and trade tape of every rung, nanosecond-stamped; the statistics on this page cover the most traded contracts per day; the bundle holds every contract listed on Kalshi that day.

Split by release or event day, never at random — every rung of one ladder settles on the same print, so the whole ladder is one example; walk forward over releases. The ladder guide works distribution labels, cross-strike features and the link to the crypto strike grids through.

Why CryptoStruct

Why buy Kalshi B200 Monthly data here

Four things every page on this site is built on — and the reason the numbers above exist at all.

We record everything

The complete public feed of each venue as it was published: every Level-2 snapshot and update at the venue's full book depth, every trade with its aggressor side, every quote, funding, mark-price and liquidation event — for every instrument the venue lists, every UTC day since we added the venue. Nothing sampled, no top-N cut, no on-demand capture.

Institutional grade

Captured co-located at the venue with the exchange timestamp and our receive timestamp in integer nanoseconds, an event-id chain that makes any gap visible, and one normalized schema across 35+ venues — the same capture our own high-frequency trading engine and enterprise feeds run on.

€1 per instrument-day

Any instrument-day is €1, series-day bundles start at €1 — no subscription, no minimum order, no tiers to unlock. Credit packs lower the effective price and never expire, and free full-day samples from the major venues let you test first.

Self-service for everyone

Pick the days in the Data Shop, pay by card as a guest and download immediately — no sales call, no enterprise contract, no KYC. Coding agents buy the same files through the MCP server, and the free Agent Skill teaches them the format.

FAQ

Kalshi B200 Monthly data — FAQ

What Kalshi B200 Monthly data can I download?

Tick-by-tick trades and Level-2 order-book depth for every contract of the B200 Monthly series on Kalshi (171 contract files on the latest day). One bundle = one UTC day of the whole series.

What is the Kalshi series ticker for B200 Monthly?

KXB200MS — every contract of the series carries this prefix in its ticker (followed by the event date and strike). Files in a day bundle are named by the full contract ticker, so a bundle holds every KXB200MS-* contract listed that UTC day.

How far back does the B200 Monthly data go?

Coverage runs June 2026 – present — 141 trading days in total.

What format are the Kalshi files in?

Can I get Kalshi B200 Monthly data as CSV or Parquet?

Yes — trades export as gzipped CSV or Parquet at no extra cost, with integer microsecond UTC timestamps that load straight into pandas, polars or DuckDB. Kalshi records full order-book depth without a separate BBO stream, so book data ships in the native tick file — the free reader script converts it locally. See the formats overview.

How is the Kalshi B200 Monthly data captured?

Co-located at the venue, message by message: every Level-2 update and every trade print carries the exchange timestamp and our receive timestamp in integer nanoseconds, an event-id chain makes any gap visible, and one normalized schema across 35+ venues means a parser written for Binance reads these files unchanged.
