Performance audit

Am I good, and am I safe, answered for any Polymarket wallet from public data. No account, no API key, nothing to install.

Scoring a forecast requires knowing what someone believed before the outcome, which is why every other tool asks traders to log a probability against each position and then wait dozens of trades to learn anything. That step is unnecessary here. Every fill on Polymarket settles on Polygon with a price and a timestamp attached, so the record already exists: the price paid is the probability revealed.

Am I good

Each row is a band of entry prices. Paid is the average price actually paid, which is the probability the wallet revealed by buying. Happened is how often those positions paid out. A well-calibrated trader has the two columns tracking each other.

A positive gap means the wallet was under-confident in that band, it won more often than the price it paid implied. Negative means over-confident.

100% of open capital sits in a single contract. A binary settles to one dollar or to nothing, so concentration here is not a question of style: a single adverse resolution takes that share of the book with it.
