Challenger ATP — did the favourite win?
The side the opening price favoured finished in the money 54 % of the time across 856 settled Challenger ATP contracts that opened away from 50 ¢ among the day's most traded contracts, 2026-08-10 – 2026-11-07. Contracts opening at 60–70 ¢ — 205 of them — closed Yes 72 % of the time.
| Opening price | Contracts | Closed Yes | Closed No | Yes share | Open at last print |
|---|---|---|---|---|---|
| 20–30 ¢ | 53 | 43 | 8 | 84 % | 2 |
| 30–40 ¢ | 104 | 77 | 25 | 75 % | 2 |
| 40–50 ¢ | 165 | 119 | 43 | 73 % | 3 |
| 50–60 ¢ | 180 | 113 | 59 | 66 % | 8 |
| 60–70 ¢ | 205 | 145 | 56 | 72 % | 4 |
| 70–80 ¢ | 115 | 83 | 30 | 73 % | 2 |
| 80–90 ¢ | 44 | 37 | 5 | 88 % | 2 |
| other opening prices | 26 | 18 | 6 | 75 % | 2 |
| Total | 892 | 635 | 232 | 73 % | 25 |
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 Challenger ATP model on this data
Every settled Challenger ATP 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.
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.

Why buy Kalshi Challenger ATP 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.
