Platinum Hourly — did the favourite win?
The side the opening price favoured finished in the money 76 % of the time across 299 settled Platinum Hourly contracts that opened away from 50 ¢ among the day's most traded contracts, 2026-08-13 – 2026-11-06. Contracts opening at 90–100 ¢ — 221 of them — closed Yes 98 % of the time.
| Opening price | Contracts | Closed Yes | Closed No | Yes share | Open at last print |
|---|---|---|---|---|---|
| 0–10 ¢ | 60 | 41 | 8 | 84 % | 11 |
| 90–100 ¢ | 221 | 207 | 5 | 98 % | 9 |
| other opening prices | 59 | 34 | 4 | 89 % | 21 |
| Total | 340 | 282 | 17 | 94 % | 41 |
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 Platinum Hourly model on this data
Every Platinum Hourly event lists a ladder of strikes — one contract per range — and the rung that settles in the money is the label, so the ladder's prices read as an implied distribution rather than one probability. The day bundle holds the full order-book path and trade tape of every rung, 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 release or event day, never at random — every rung of one ladder settles on the same print, so the whole ladder is one example; walk forward over releases. The ladder guide works distribution labels, cross-strike features and the link to the crypto strike grids 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 Platinum Hourly 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.
