Polymarket settlement-quality register
Frozen summaries of 123,499 settled UMA requests, window 2023-12-05 to 2026-08-12. Among settled disputes, 7.12% changed the proposal. Group summaries cover category and rule-text features.
Files and viewer
The viewer loads the canonical aggregate snapshot only. The dated files preserve export history and are not independent observations.
Method and source
See the embedded metadata and repository inventory. Files are frozen aggregate exports from experimental research by Ailin Sun, an independent researcher. Research numeric values are unchanged.
Limitations
Dates in snapshot filenames can refer to exports of the same source window. Rates are conditional on the observed sample, not causal estimates or individual-market forecasts. Infrastructure endpoint identifiers are omitted. Source request-level data is not included.
