Calibration curve

Each bucket groups resolved positions by average entry price. Compare avg price (what the market implied) to outcome rate (how often that side paid). Well-calibrated traders keep those numbers close across buckets with enough n.

Most resolved positions sit in bucket 0.00-0.10 (n=149). Heavy concentration in cheap long-shot or near-certain prices can dominate headline Brier — read sparse buckets with caution.

How to read this oracle profile

This page is a resolved-market accuracy dossier for 0xe881388fdad5d7d80540c1352f721e6db52a19ab. It does not show open positions, mark-to-market PnL, or Smart Score — those live on the full trader analytics page.

  • Brier — aggregate squared error vs 0/1 outcomes; ~0.25 is a coin-flip baseline.
  • Accuracy — share of resolved positions that paid in the trader's favor.
  • Volume / n — sample size. High accuracy on tiny notional is weak evidence.
  • Calibration — whether cheap entries actually win rarely and expensive ones win often.

Research only — Polydata never executes trades. Cross-check the leaderboard, methodology, and Polymarket analytics before drawing conclusions.
