?New here? What this page meansShow
This page shows where proven winners are putting real money today. Sharps are Polymarket's most profitable sports traders. Whales are anyone placing a single $2,500+ bet on Kalshi. Each row tells you the team they're backing, what they paid, and a green button to make the same bet on the exchange with the cheapest price right now. It's a signal, not a guarantee: sharps lose plenty of bets too.
Sharp
A bettor or trader with a long, proven record of winning, usually by betting before prices move. A casual bettor is called a square.
Whale
A trader placing a very large bet. We flag every single Kalshi trade of $2,500 or more on today's games.
Example: $40K traded on the Nets at 52¢ = a whale backing the Nets.
Following (tailing) a bet
Making the same bet a sharp, whale or capper made: back the same team, ideally at the same price or cheaper. The opposite is fading them.
Entry price (avg entry)
The average price a trader paid for their position. If the price is higher now, they're already up on paper, and following them costs you more than it cost them.
Yes / No
Every Kalshi contract has two sides. Buying Yes on "Nets win" bets the Nets win; buying No bets they don't. So a big No on one team is really a bet on the other team.
Polymarket
A prediction market like Kalshi. Polymarket US is the app US users can sign up for. The top-trader leaderboard comes from Polymarket's separate international exchange; prices are usually close.
