ATP Challenger Doubles Match — did the favourite win?
The side the opening price favoured finished in the money 64 % of the time across 217 settled ATP Challenger Doubles Match contracts that opened away from 50 ¢ among the day's most traded contracts, 2026-09-22 – 2026-10-22. Contracts opening at 60–70 ¢ — 53 of them — closed Yes 75 % of the time.
| Opening price | Contracts | Closed Yes | Closed No | Yes share | Open at last print |
|---|---|---|---|---|---|
| 30–40 ¢ | 31 | 14 | 15 | 48 % | 2 |
| 40–50 ¢ | 43 | 29 | 13 | 69 % | 1 |
| 50–60 ¢ | 48 | 31 | 16 | 66 % | 1 |
| 60–70 ¢ | 53 | 39 | 13 | 75 % | 1 |
| 70–80 ¢ | 25 | 19 | 5 | 79 % | 1 |
| other opening prices | 34 | 18 | 10 | 64 % | 6 |
| Total | 234 | 150 | 72 | 68 % | 12 |
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 ATP Challenger Doubles Match model on this data
Every settled ATP Challenger Doubles Match 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. 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 ATP Challenger Doubles Match 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.
