Prediction-market data sources
See how provider records, recorded market values, and PlayPicks analysis are kept distinct.
On this page
Every observation has a source
For each market value we show, we keep the provider, the source link and the time it was recorded. Contract rules and dates are shown separately from prices, and each page explains what a value means and when one is unavailable.
How we treat dated market values
Market observations carry their original capture times. A recorded value is a historical record, not a live quote. Missing quote types, fees or depth remain unavailable rather than being inferred from another product.
Provider data and our analysis
Contract wording is linked at its source. PlayPicks analysis explains material differences in our own words. The date a page was checked and the time a market value was recorded are shown separately.
How to read a source record
Check the product named by the source before reading its terms. An exchange rulebook, a broker’s account agreement and a help article may apply to different parts of the same experience. A source about one product does not establish a feature of another.
Next compare the source inspection date with the date of the value shown. Inspecting a document today does not update an earlier price. Where a provider timestamp conflicts with the capture record, the discrepancy stays visible and the value is not described as live.
