Polymarket wallets that buy both sides
Buying Yes and No in the same market is not a view on the outcome. It is arbitrage — both sides bought for under a dollar together — or a hedge against a position somewhere else. Either way the profit is in the prices the wallet got, not in which side wins.
A copier gets neither price. It buys each leg later and higher, and the few cents of margin the trade was built on are the first thing the delay and the spread take.
39 wallets, by all-time profit
A wallet is here when it buys both outcomes in 50% or more of its markets. The first columns are the numbers each wallet fails it on. We check every wallet that has made Polymarket's all-time or 30-day top 100, overall or in Crypto, every day. For 8 of these 39 it is the first check they fail; the last column names the first one for the rest.
