About WhaleSays

WhaleSays is an independent website that shows public trading activity from Polymarket, a prediction market. We show large trades, the traders who place them, and the odds on major world events. WhaleSays is not affiliated with or endorsed by Polymarket.

What we show

• Whale trades. Every Polymarket trade worth $10,000 or more, shown on our feed about every minute.
• Trader profiles. Leaderboards and profile pages built from each trader’s public positions and trades.
• Event odds. Live odds for the most traded questions on Polymarket, from elections and sports finals to Fed decisions.

Read how the numbers are produced on our methodology page. The feed itself is on live whale trades.

Built on public data

WhaleSays does not run its own market. Everything we show comes from Polymarket’s public data. We filter and format that data, and the rules we apply are published on our methodology page.

How we make money

Some links to Polymarket are affiliate links. If you sign up through one and trade, we may receive a share of the trading fees you pay, at no extra cost to you. Affiliate links never change the data we show. Full details are in our affiliate disclosure.
