Politics 0x8b4bca1d794779e66e023d44391b2a86c5ab541b Profile on Polymarket

ProvisionalIncludes trades from the last ~40 minutes, so these results may still change. Computed Oct 26, 2026, 02:01 UTC.

Only 15% of this trader's buys could be fully copied at a 5-minute delay, and another 9% only partly; the +$1,067 comes from the part you could copy. A copier who mirrored 0x8b4b…541b's 1,294 buys across 102 markets with a 5-minute delay and $100 per trade would have ended at +$1,067. The leader lost $832.35 at the same size, so there were no returns to keep; the copier only came out ahead because later prices happened to be better: the delay helped by +$2,085, slippage $2.39 and fees $183.67. In the backtest, this simulated copy would have tied up to $14,727 at once across 309 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. 936 estimated: 204 high · 597 medium · 135 low · 157 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.
