realized edge +5.5 pp, 95% CI [-0.4, +11.3], n=187
Realized edge +5.5 probability points across 187 scored resolved positions, 95% CI [-0.4, +11.3]. These figures describe the recent-trade window this read covered, not the wallet's whole resolved record, so they cannot be read as an edge either way. A Convexly read of the public record.
Diagnostics on public behavior, not investment advice. Demonstrated past skill is not a forecast. The figures describe the window this read covered, which omits redeemed positions and is not the full resolved record. This caveat travels with the badge in every view.
A methodology-cited read of this wallet's public Polymarket record, taken from the venue's recent-trade window. The statistics below describe that window, not the wallet's whole resolved record.
Sample quality: StrongLarge scored resolved sample. The rating is still historical and cross-sectional, but the noise floor is lower.

Read coverage
Covers the most recent 3,500 trades the public API returns for this wallet. Older history beyond that window is not included in this read.
Frozen research snapshot
On the frozen 2026-04-25 research snapshot (sub-daily crypto up/down micro-markets excluded), this wallet had 60 resolved positions with a win rate of 55.0% and a realized edge over entry prices of -1.9 probability points, 95% CI [-12.8, +8.6] (BCa bootstrap); the 95% interval includes zero, so on that snapshot the edge is not separable from chance.
Did not clear the Benjamini-Hochberg false-discovery screen at q = 0.1 on that snapshot (178 of 3871 wallets cleared). That means no corrected evidence of skill on the snapshot, which is not the same as evidence of no skill. In-sample separation on a frozen snapshot, not validated forward skill.
The frozen snapshot does not carry the single-event concentration screen that the live analyzer applies; the realized-edge read above (when present) is the concentration-screened read.
Brier gap (baseline minus Brier): +0.0266. Descriptive only: no interval is computed for this gap on this surface. The interval-backed skill read on this page is the realized-edge block. Brier is scored lower-is-better against resolved outcomes; the baseline is a constant base-rate forecast on the same positions.
Biggest event: Portugal vs. Spain (17.4% of the net result; shares above 100% mean the remaining events netted negative)
Category breakdown
Descriptive per-category reads; none is an FDR-cleared skill claim unless labeled. Categories with fewer than 3 resolved positions are excluded by the analyzer; small per-category samples are noisier than the headline sample.
