Questions

Where does this come from?

Polymarket’s international exchange: every $1K+ buy on a sports game, graded when the market settles. Tracking began in October 2026. Biggest trades also include Kalshi, which doesn’t show who traded.

Is this Polymarket US?

No. Polymarket US is a separate exchange with its own prices, and it doesn’t show who placed each trade, so there’s nothing to rank. Prices on the two are usually within a few cents.

How are traders ranked?

By settled trades in the window you pick. Buys under 95¢ count; sells don’t. Ranking takes 10 settled trades (3 in 24 hours, 5 in 3 days), and several fills on the same side count as one trade.

How is profit calculated?

Each winning share pays $1. $100 at 40¢ buys 250 shares, so a win returns $250: +$150. A loss is the $100. Fees aren’t included.

How often does it update?

Latest trades within a minute, prices every minute, leaderboards about every 10 minutes. No need to refresh.

Should I follow these traders?

This isn’t advice. Big traders lose often, so check their record and compare today’s price with what they paid. Names link to their Polymarket profiles.
