Sports 0x9a3fa403a6666eef75f92f181fcf13f9c051914a Profile on Polymarket

Provisional4 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, 02:19 UTC.

Only 29% of this trader's buys could be fully copied at a 5-minute delay, and another 11% only partly; the +$1,401 comes from the part you could copy. A copier who mirrored 0x9a3f…914a's 3,311 buys across 637 markets with a 5-minute delay and $100 per trade would have kept only 11% of the leader's returns: +$1,401 against +$12,568 for the leader at the same size. Most of the edge is eaten before a follower can act: delay cost $10,234, slippage helped by +$1,097 and fees $2,030. In the backtest, this simulated copy would have tied up to $23,558 at once across 1,299 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. 1,435 estimated: 601 high · 530 medium · 304 low · 849 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.
