Kalshi is a US-regulated exchange where every contract is a yes/no question with a price between 0 and 1. AymarData records order-book snapshots, deltas and trades for a curated list of the series that matter most, starting on 2026-10-01. Recording is forward-only: no backfill, a complete tape from day one.
The Batch-1 list is exact: KXBTCD, KXETHD, INXD, Fed, KXCPI, KXGDP, KXUNRATE, KXWEATHER, KXEARNINGS, KXOIL, KXGASS, KXHOGS, KXRATECUT, KXTRUMP, KXELECTION, KXSCOTUS, KXBTCMAX, KXETHMAX, KXSPX and KXNASDAQ.
Each series page covers the instrument's structure, what moves it, coverage numbers, the schema, sample rows and ready-to-run snippets. Series with very little recorded volume are kept out of search indexes until they grow.

Is there Kalshi history before October 2026?
No. Kalshi is recorded live from 2026-10-01 and is forward-only; there is no backfill.
How do I find the full ticker for a contract?
Series tickers are prefixes such as KXBTCD; a contract ticker adds the settlement date and strike, for example KXBTCD-26OCT2617-T67000. Use search_markets in the MCP server or /v1/markets to list contracts in a series.
