Is 0x903221b1… really profitable on Polymarket?
0x903221b1098263779ae19486028c844e8c338717
Short answer
Less than the leaderboard suggests. 0x903221b1… made Polymarket's daily leaderboard on 61 days (2026-04-25 to 2026-09-21), adding up to $500K on those days. Verified lifetime PnL is only +$414K: a gap of $86K that can only come from losing days the board never shows. Recent windows from Polymarket: last week +$7K, last month -$2K.
