Politics 0xbacd00c9080a82ded56f504ee8810af732b0ab35 Profile on Polymarket

Only 19% of this trader's buys could be fully copied at a 5-minute delay, and another 13% only partly; the −$8,758 comes from the part you could copy. A copier who mirrored 0xbacd…ab35's 4,696 buys across 326 markets with a 5-minute delay and $100 per trade would have ended at −$8,758. The leader lost $13,474 at the same size, so there were no returns to keep: the delay helped by +$6,063, slippage helped by +$135.16 and fees $1,482. In the backtest, this simulated copy would have tied up to $49,233 at once across 1,480 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. 2,383 estimated: 470 high · 1,261 medium · 652 low · 1,318 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.
