Why CryptoStruct

Why buy Ethereum 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

Ethereum prediction-market data — FAQ

Does Kalshi have Ethereum markets?

Yes — ETH Up/Down 15m (KXETH15M), Ethereum price above/below (KXETHD) and Ethereum range (KXETH). Polymarket lists ETH Up/Down at 5m, 15m, 1h and 4h plus price-strike and multistrike families.

How is Ethereum prediction-market data sold?

One purchase covers every contract of the series for one UTC day — every trade print and the complete Level-2 book per contract, captured co-located with nanosecond timestamps — €1 per series-day, bought as a guest with instant download.

How far back does the Ethereum data go?

Coverage runs May 2025 – present — 2,987 series-days across 11 series on Kalshi & Polymarket. Each series page lists its exact span.

Can I get Ethereum prediction-market 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. Both venues record 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 Ethereum prediction-market data cost?

€1 per series-day bundle — every contract of the series for that UTC day — no subscription, no minimum order. Pick days in the shop calendar, pay as a guest, download immediately.

Do I need an account or a sales call?

No. Pick the Ethereum 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 Ethereum 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 was the busiest Ethereum trading day?

2026-09-21 — $6.6M of USD turnover over 520,516 trades in a single series-day. Since our statistics began on 2026-07-08, 10 Ethereum series recorded 29,696,126 trades and $373.0M in total; the biggest single contract was KXETH15M-26SEP132230-30 on 2026-09-14 at $185.8K. Mondays are the busiest weekday at about $7.2M per day.

How often did Ethereum contracts resolve Yes vs No recently?

46 % of 10,727 resolved contracts closed Yes and 54 % closed No by their last recorded print over the 14 captured days to 2026-09-22, about 560 trades per contract. Implied from the market (≥ 0.97 / ≤ 0.03), not the official settlement.
