What counts as a "win" on this leaderboard?+
A whale-sized trade that we tracked on Polymarket or Kalshi where the market resolved in favor of the side the bettor took. We calculate paper PnL assuming hold-to-resolution, so the number is what the bettor would have made if they'd held the contract through settlement.
Are these realized profits?+
No. We report paper PnL on the entry trade. Some whales exit early at a smaller profit, roll into another position, or double down. The number here is the most favorable interpretation of the original entry, which is the consistent way to rank trades across platforms.
How often is the leaderboard updated?+
The resolver runs every 12 hours and marks newly settled trades. The page itself is cached at the edge for an hour with revalidation, so you're seeing data that's at most an hour old on any given visit.
Why are biggest wins almost always longshot bets?+
A $50K bet on a 0.10 longshot pays $450K if it hits. A $50K bet on a 0.60 favorite pays $33K. The math is structural. To put up a six-figure win you either need a massive stake on a coinflip or a moderate stake on a contested price.
