Single contracts ranked by USD turnover on 2026-10-24 (UTC), from every trade print in our tick archive. Prices quote 0..1; the implied outcome reads the last print of the day (≥ 0.97 Yes/Up, ≤ 0.03 No/Down) — venues publish the official result. Each contract’s day file is sold individually, the whole series day as a bundle.

Why CryptoStruct

Why buy politics prediction-market 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

Politics prediction-market data — FAQ

What politics prediction-market data can I download?

Tick-by-tick trades and Level-2 order-book depth for every contract of 193 politics series on Kalshi & OG.com & Polymarket — midterm margins of victory, House races, primary vote shares. Each series page lists its exact coverage and day count.

How far back does the politics data go?

Coverage runs November 2025 – present — 35,269 series-days in total across the category.

Is every politics contract included?

Yes — every contract of every listed series, every UTC day since we added the venue, at full order-book depth; nothing is sampled or cut to a top-N. The tables on this page show the largest series, the archive holds all of them.

How is the politics data sold?

As series-day bundles: one purchase covers every contract of a series for one UTC day, €1 — no subscription, no minimum. Pick days in the shop calendar; delivery is per file, one ZIP per day, or a resumable multi-day archive.

Why are politics turnover figures small compared with sports?

Election contracts trade for weeks or months and thinly; the value of the archive is the long order-book history per race — quotes that move on news — not the trade tape. Every day bundle records the full Level-2 book of every contract of the series.

Are non-US elections covered?

Yes — the world elections hub lists the families outside the United States that the venues have listed.

Do I need an account or a sales call?

No. Pick the politics 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 politics 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.

What format do the files ship in?

One zstd-compressed text file per contract per UTC day, in the same documented schema as every crypto venue; trades also export as gzipped CSV or Parquet at no extra cost. Free samples are on the downloads page, the schema in the market-data specification.

How is politics turnover split between venues?

Over the 30 days to 2026-10-24: Kalshi $16.8M (83 %, 820,564 trades) · Polymarket $3.5M (17 %, 174,383 trades) · OG.com $1.6K (0 %, 445 trades) — summed from every trade print of every politics series with statistics on each venue.

What was the busiest politics trading day?

2026-08-12 — $5.1M of USD turnover over 35,697 trades in a single series-day. Since our statistics began on 2026-07-08, 171 politics series recorded 3,751,831 trades and $60.5M in total; the biggest single contract was KXGOVFLNOMR-26-BD on 2026-08-18 at $4.0M.
