0xfea31bc088000ff909be1dfd8d0e3f2c7ef2d227
Short answer
Mostly yes. ndb1 made Polymarket's daily leaderboard on 96 days (2026-04-18 to 2026-10-29), adding up to $2.40M on those days. Their verified lifetime PnL is +$2.76M, at least as much as the board days imply, so the leaderboard is not hiding a pile of losing days. Recent windows from Polymarket: last week -$266K, last month +$305K.
