Crypto 0x80cd8310aa624521e9e1b2b53b568cafb0ef0273 Profile on Polymarket

Only 8% of this trader's buys could be fully copied at a 5-minute delay, and another 8% only partly; the −$51.66 comes from the part you could copy. A copier who mirrored 0x80cd…0273's 1,022 buys across 72 markets with a 5-minute delay and $100 per trade would have ended at −$51.66. The leader lost $1,719 at the same size, so there were no returns to keep: the delay helped by +$1,981, slippage $101.22 and fees $212.59. In the backtest, this simulated copy would have tied up to $2,853 at once across 166 positions.

Copy delay

Each time the trader buys, the simulation copies this much. Not a total budget.

The headline numbers only count what real trades in the 10 minutes after the delay prove. “Including estimates” also counts the unproven part of a buy when order-book or trading-volume evidence says it was fillable, at an estimated price. Treat it as an upper view, not a promise. 415 estimated: 7 high · 203 medium · 205 low · 499 thin How we estimate

Leader PnL is scaled to your per-trade size. Delay cost is the price move between the leader's fill and yours; slippage is walking the book to fill your size; fees use the 2026 fee schedule. Methodology.

Trades

Each leader buy and the copy we simulated at the selected delay. Open “Details” to see the market fills behind the copy price.

How fills are simulated: a copy can only fill against real taker buys of the same outcome within 10 minutes after the delay, so the headline numbers are conservative. Fill basis adds a second opinion: where no trade proved a fill, order-book or volume evidence may say the size was still fillable (an estimate, never in the headline). Methodology.
