Next Labor Sec on Kalshi — activity
Per-day trade and turnover statistics exist from July 2026 onward — a limit of the statistics, not of the capture: older days are archived in full (every contract, every message) without a statistics row.

Event contracts quote 0..1; turnover is USD-normalized.
Coverage runs April 2026 – October 2026 — 165 trading days, 20.9 MB compressed in total. A day typically holds 15 contract files (up to 16 on the busiest day, 1.32 MB). Pick individual days in the shop calendar for €1 each; delivery is an instant per-file download or one archive for the whole day.

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 Next Labor Sec model on this data
Every resolved Next Labor Sec contract is a labelled example that trades for weeks or months, not minutes: the label is the race outcome, the margin bucket or the nominee, and the signal in between is mostly the order book — quotes move on news while trades stay sparse. The day bundle holds each contract's full Level-2 book path and every trade of that UTC day, 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 election cycle and by race, never at random — months of quotes on one contract are one regime, and a random split leaks the result backwards; validate across races and cycles, not within one. The election-markets guide works thin books, book updates as the main signal and calibration over months through.

Why buy Kalshi Next Labor Sec 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.
