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.

Bucket	Avg price	Outcome rate	n	Brier
0.00-0.10	1.0¢	0.0%	1	0.000
0.10-0.20	15.1¢	0.0%	2	0.024
0.30-0.40	36.0¢	100.0%	1	0.410
0.40-0.50	46.6¢	40.0%	5	0.253
0.50-0.60	54.6¢	46.4%	28	0.261
0.60-0.70	64.5¢	76.9%	52	0.192
0.70-0.80	75.0¢	72.7%	55	0.199
0.80-0.90	84.4¢	83.9%	56	0.133
0.90-1.00	98.9¢	98.4%	1,281	0.015

Most resolved positions sit in bucket 0.90-1.00 (n=1,281). 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 0x8900625cd0e1c8ddf8c0c702d14772fd2a4d5c77. 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.
