In backtest, only 18% of 0xbeb1…4687's buys could be fully copied at a 5-minute delay

Sports 0xbeb1c94b4260398f93f418e349a15a40b2ae4687 Profile on Polymarket

Only 18% of this trader's buys could be fully copied at a 5-minute delay, and another 9% only partly; the +$43,891 comes from the part you could copy. A copier who mirrored 0xbeb1…4687's 4,868 buys across 200 markets with a 5-minute delay and $100 per trade would have kept 92% of the leader's returns: +$43,891 against +$47,907 for the leader at the same size. In this backtest, most of the edge survived the delay, and 18% of buys could be filled within 10 minutes. The remaining gap is delay cost $1,562, slippage helped by +$44.61 and fees $2,499. In the backtest, this simulated copy would have tied up to $24,940 at once across 1,324 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. 2,693 estimated: 0 high · 2,113 medium · 580 low · 1,212 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.
