Opening price vs outcome

Japan NPB Game — did the favourite win?

The side the opening price favoured finished in the money 57 % of the time across 460 settled Japan NPB Game contracts that opened away from 50 ¢ among the day's most traded contracts, 2026-08-09 – 2026-10-28. Contracts opening at 50–60 ¢ — 164 of them — closed Yes 58 % of the time.

Total51726021555 %42

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.

Polymarket also lists NPB event markets — the same 30-day statistics side by side, each a day bundle of its own.

30-day window of the statistics table, per venue's own series; spread in contract-price cents and best-bid/ask depth are turnover-weighted, L2 updates per trade = recorded order-book level updates ÷ trades. "—" = no statistics row in the window. Each venue settles its own contracts on its own rules — the series are comparable in subject, not interchangeable.

Build a Japan NPB Game model on this data

Every settled Japan NPB Game 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 Japan NPB Game 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.
