What if you had copied them?

Put a fixed stake on every graded flag a wallet made, at the price it paid, and see the hypothetical result. This looks backward only, and it is not a prediction or a recommendation.

Why this overstates what you'd get

  • You'd be late. Flags show up after the trade, often after the price has moved. Use "Copy delay" to price each bet 1 to 24 hours later from market history, or add an extra cost per fill.
  • Picked after the fact. Wallets that look good here were chosen because they did well. Tick the out-of-sample box to test only bets made after the cutoff.
  • Small samples are noisy. Look at the ± standard error. A few lucky long shots can make the P&L.
  • Fees: many Polymarket markets charge no trading fee. Some charge a taker fee of rate × min(price, 1−price) per share. Set "fee rate" to model it.
  • Ignores spreads, liquidity, partial fills, and sells before resolution. It counts only graded flags (placed ≥1h before close, 3¢–97¢).
