Why CryptoStruct

Why buy Kalshi H100 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 every venue has free full-day samples to test against 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 H100 Monthly data — FAQ

What Kalshi H100 Monthly data can I download?

Tick-by-tick trades and Level-2 order-book depth for every contract of the H100 Monthly series on Kalshi (112 contract files on the latest day). One bundle = one UTC day of the whole series.

What is the Kalshi series ticker for H100 Monthly?

KXH100MS — 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 KXH100MS-* contract listed that UTC day.

How far back does the H100 Monthly data go?

Coverage runs July 2026 – present — 87 trading days in total.

What format are the Kalshi files in?

One zstd-compressed text file per contract per UTC day, in the same normalized schema as our crypto venues — see the market-data specification; free samples on the downloads page.

Can I get Kalshi H100 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 much does Kalshi H100 Monthly historical data cost?

€1 per series-day bundle — every contract of the series for that day — no subscription, no minimum order; buy as a guest in the Data Shop and download immediately. Credit packs lower the effective price and never expire.

Do I need an account or a sales call?

No. Pick the H100 Monthly series-days in the Data Shop, pay by card as a guest and download immediately — no subscription, no minimum order, no KYC, no enterprise contract, no sales call. Coding agents buy the same bundles through the MCP server.

How is the Kalshi H100 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. It is the same capture our own high-frequency trading engine runs on — nothing sampled, no top-N cut.

How many H100 Monthly contracts trade per day on Kalshi?

On average 8 H100 Monthly contracts had at least one trade per UTC day over the last 30 captured days on Kalshi, with about 41.6K order-book level updates recorded per day. A day bundle contains every contract file of the series for that day.

These figures are computed from the recorded Level-2 order books and trade prints — the same data in the day bundles.
