How these tools work

Tracking tools answer one question: who is making money on Polymarket and Kalshi, and what are they holding right now. They range from the venues' own profit leaderboards to wallet checkers, whale-trade feeds with insider scoring, statistically screened alert rosters and copy-trading screens that score whether a trader's edge survives being copied.

Polymarket wallets are public on-chain, so the Polymarket side of this category is crowded and mostly free: Polymarket Analytics, PredictFolio, PolyWallet and Predicts.guru all let you read any wallet's P&L and win rate for nothing. Kalshi traders are ID-verified but opted out of the exchange leaderboard by default, so Kalshi tracking is thinner and paid: KalshiSpy sells consensus positions at $61 per month, and cross-venue feeds such as Polywhaler and WhaleScanr bridge the gap by pointing Polymarket signals at Kalshi markets.

None of these tools execute. Every one of them ends at a link to the venue, which is fine for a weekly review and a problem for a 30 second whale alert.

How to choose

Questions about leaderboards & whales tools

What is the best Polymarket whale tracker?

For a free cross-venue feed with scoring, Polywhaler. For paid Telegram alerts on top wallets, SightWhale. For a raw threshold feed you run yourself, the open-source polymarket-whales script. Each is reviewed on this site.

Is there a Kalshi leaderboard?

Kalshi has one, but users are opted out by default so it shows a self-selected subset. KalshiSpy ranks verified Kalshi traders by realized P&L and groups their positions by market for $61 per month; WhaleScanr points screened Polymarket signals at Kalshi markets for $19 per month.

How do I copy trade on Polymarket?

Pick a wallet from a tracker that shows completed-trade win rate and P&L, then follow it. Polycopy does the follow-and-copy loop, free for manual copying and $30 per month plus 0.5% per trade for bots. Polymarket itself has no native copy feature.
