In backtest, only 22% of 0x876b…1703's buys could be fully copied at a 5-minute delay

Tech 0x876bb030ddd424ef505ae02914024cf18c6a1703 Profile on Polymarket

Only 22% of this trader's buys could be fully copied at a 5-minute delay, and another 18% only partly; the +$4,874 comes from the part you could copy. A copier who mirrored 0x876b…1703's 472 buys across 160 markets with a 5-minute delay and $100 per trade would have kept only 41% of the leader's returns: +$4,874 against +$11,893 for the leader at the same size. Most of the edge is eaten before a follower can act: delay cost $6,159, slippage $457.83 and fees $401.87. In the backtest, this simulated copy would have tied up to $6,584 at once across 188 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. 325 estimated: 104 high · 159 medium · 62 low · 41 thin How we estimate

  5. Follower PnL+$4,874

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.
