AymarData records full order books and trades for prediction markets and crypto venues. This catalog has a page for each instrument we actively cover — and each page is written for that instrument, with its own coverage numbers, schema, sample rows and ready-to-run snippets.

Polymarket and Binance history begins on 2025-06-01. Hyperliquid and Kalshi are recorded live from 2026-10-01, forward-only. Across the 100 instrument pages below there are about 247.2M recorded events.

Because the sources share timestamp conventions, you can join them: Polymarket Up/Down windows against Binance spot, Binance perps against Hyperliquid, Kalshi crypto ladders against both. The related-market links on each page point to the natural comparisons.
