Finance 0x8888a4f8c8d3834482d77405530d7f5428a40b39 Profile on Polymarket

Provisional2 buys are too recent to evaluate at this delay: the market data after them isn't indexed yet, so they're left out of these numbers. Computed Oct 26, 2026, 02:05 UTC.

Only 9% of this trader's buys could be fully copied at a 5-minute delay, and another 11% only partly; the +$2,693 comes from the part you could copy. A copier who mirrored 0x8888…0b39's 2,997 buys across 98 markets with a 5-minute delay and $100 per trade would have kept only 46% of the leader's returns: +$2,693 against +$5,912 for the leader at the same size. Most of the edge is eaten before a follower can act: delay cost $1,678, slippage $542.39 and fees $998.26. In the backtest, this simulated copy would have tied up to $9,641 at once across 592 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.

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.
