MLB Announcers 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.
One purchase, the whole series for a day
A series-day bundle contains every MLB Announcers contract that was listed on Kalshi on that UTC day — traded or not — 95 contract files on the latest covered day. Each file carries the full raw feed: every trade print with price, size and side, plus Level-2 order-book updates, in the same zstd-compressed schema as our crypto venues. Event contracts quote 0..1; turnover is USD-normalized.
Coverage runs March 2026 – August 2026 — 135 trading days, 1.73 GB compressed in total. A day typically holds 106 contract files (up to 380 on the busiest day, 111 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.

Every one of them is in the day bundle of its day.
Build a MLB Announcers model on this data
Every resolved MLB Announcers contract is a labelled example — a count, a score, a date or a name — and the day bundle holds its full order-book path and trade tape, 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 time, never at random — adjacent contracts share a regime, and a random split leaks it into the test set. The training-data hub covers labels, leakage and walk-forward validation.
Purchased data is for your own use — backtesting, research, analytics and training your own models, in-house or in your own products; the trained models and derived data you build from it are yours. The raw files and tick streams themselves may not be redistributed, resold or published. The full terms are on the data license page.
Why buy Kalshi MLB Announcers 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 free full-day samples from the major venues let you test 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.
