Polymarket lists 200 settled positions for this wallet. Of them, 109 (55%) ended in profit and 91 in a loss, for a net +$17K in profit and loss. The simple average entry price on them was 37%; 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 4 largest positions on markets that have not ended, listed below and worth $9,342 together, the biggest is “Will Marco Rubio win the 2028 US Presidential Election?” (No) at 68% 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 (13 of the 200 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.
