Profit is the number everyone looks at, and on Polymarket it is the least reliable one. This guide shows the check that actually separates skill from luck, how to run it on any wallet yourself, and what else to look at before you follow anyone.
Polymarket markets pay all-or-nothing. Buy at 3¢, win, and that one bet covers a hundred losing ones. So a trader can be far ahead on the leaderboard from a handful of long shots and still have no real edge — and luck does not repeat just because you are watching it. On a leaderboard a sharp trader and a lucky one look identical.
On Polymarket, price is probability. Buying at 30¢ means the market thinks that outcome happens about three times in ten. So for any trader you can ask: did they win more often than their own entry prices said they would? Winning six out of ten bets bought at 30¢ is something bet sizing and long odds cannot fake.
When we first tested a set of profitable wallets this way, they had won 2,104 times across 3,532 settled markets, where their own entry prices implied about 2,087. They had made money, but there was no measurable skill in it.
Wallets that do beat their prices exist; they are just rare. One we looked at won 723 of 1,211 settled markets where its prices implied about 615 — the kind of gap that is very hard to put down to luck.
Lockstep Markets runs exactly this check on any public wallet — wins against what the prices implied, the edge in standard deviations, how fast the markets are, and whether one market carries the result — and gives a plain verdict. The wallet analyzer is free to try, and if a trader holds up you can copy their trades.
Every figure here describes settled history. A trader who has beaten their prices can stop doing so, and nothing here is advice.
