Polymarket lists 170 settled positions for this wallet. Of them, 130 (76%) ended in profit and 40 in a loss, for a net +$8,184 in profit and loss. The simple average entry price on them was 74%; below 50% means that, on average, the trader bought outcomes the market rated less likely than not. Positions on markets that have not ended are not counted above. Of the 11 largest positions on markets that have not ended, listed below and worth $7,035 together, the biggest is “Will Manchester City be relegated from the 2026-27 Premier League?” (Yes) at 27% of that value.
How we count: a position is one outcome of one market. It is settled when the trader sold or redeemed it, or when its market resolved while the trader still held it; Polymarket keeps listing that last kind as open until it is redeemed, so we read those too (5 of the 170 here). Positions that cost under $1, ones that ended exactly even and ones on markets still running are left out, and each position is dated by its last activity. Profit is Polymarket's own figure per position. Computed by WhaleSays from public Polymarket data; it describes the past and is not a forecast.
