Kalshi Pro Baseball Home Runs — trades and USD turnover summed per calendar month (UTC) over every contract, from our own daily statistics of the recorded tick data.

Opening price vs outcome

Pro Baseball Home Runs — did the favourite win?

The side the opening price favoured finished in the money 45 % of the time across 444 settled Pro Baseball Home Runs contracts that opened away from 50 ¢ among the day's most traded contracts, 2026-08-09 – 2026-10-29. Contracts opening at 10–20 ¢ — 360 of them — closed Yes 55 % of the time.

Opening priceContractsClosed YesClosed NoYes shareOpen at last print
0–10 ¢75402166 %14
10–20 ¢36013010555 %125
20–30 ¢248717250 %105
other opening prices72340 %2
Total69024320155 %246

Opening price = the contract's first recorded print on the first day it ranked among the day's ten most traded contracts of the series (not its listing price), grouped in 10 ¢ steps (contracts quote 0..1 = 100 ¢). Outcome implied by its last recorded print across the window (≥ 0.97 = Yes, ≤ 0.03 = No; the rest still open at the last print) — venues publish the official result, we record the market. The sample is the daily top-10 by turnover, so it leans towards the closest, most traded contests. Deciles with fewer than 20 contracts are folded into one row.

Build a Pro Baseball Home Runs model on this data

Every settled Pro Baseball Home Runs contract is a labelled example: the winner, the line or the total that cleared is the label, and the day bundle holds each contract's full order-book path and trade tape, nanosecond-stamped, from the first quote days before the event to the last print — the features for that label. The statistics on this page cover the most traded contracts per day; the bundle holds every contract listed on Kalshi that day.

Split by season and match day, never at random — the contracts of one slate share injuries, weather and the same public money, and a random split leaks the slate's results into training; walk forward over game days and purge the days whose contracts were still open. The sports-model guide works the closing-line benchmark, the pre-game line path and that split through.

Why CryptoStruct

Why buy Kalshi Pro Baseball Home Runs 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.

Can I get Kalshi Pro Baseball Home Runs 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.

How is the Kalshi Pro Baseball Home Runs 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.
