Opening price = the contract's first recorded print on the first day it ranked among the day's ten most traded contracts of the series (not its listing price), grouped in 10 ¢ steps (contracts quote 0..1 = 100 ¢). Outcome implied by its last recorded print across the window (≥ 0.97 = Yes, ≤ 0.03 = No; the rest still open at the last print) — venues publish the official result, we record the market. The sample is the daily top-10 by turnover, so it leans towards the closest, most traded contests. Deciles with fewer than 20 contracts are folded into one row.

Build a Low Temperature Boston model on this data

Every Low Temperature Boston 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 Low Temperature Boston 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.

Can I get Kalshi Low Temperature Boston 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.

€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.

How is the Kalshi Low Temperature Boston 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.
