"Whales" are bettors who move real money — when several of them back the same side on a game, that's a signal worth watching. We track them anonymously on Polymarket, plus Kalshi and DraftKings' own sharp-money splits, and rank each whale by how they've actually performed, not by how big their bet is. Click any player row for their full track record.

🐋 Smart money is ranked by track record, not bet size — proven winners on top, big-but-losing money sinks to the bottom as a fade signal, identities masked. "Last 30 days" is profit divided by money risked over that window. 🔥 hot 30d means that wallet's ROI has been especially strong lately. 📊 Kalshi market is the latest pricing from the regulated exchange — not tied to any one trader. ⚖️ VSIN splits show where the sharp money sits per market, from DraftKings handle data.
