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
- Venue first. Only Polywhaler and WhaleScanr in this list carry both venues in one feed; everything else is Polymarket-only except KalshiSpy, which is Kalshi-only.
- Ranking versus screening. The Polymarket leaderboard ranks by profit and volume alone. If you plan to copy anyone, use a tool that shows win rate, ROI and completed-trade history, and prefer one that discloses its rule (WhaleScanr's two-standard-error test, Polycopy's cost-adjusted Copy Score) over an undisclosed model.
- Alerts cost money. Free tiers are pages you watch; Telegram or Discord pushes start at $9 per month (Polywhaler Pro) and run to $59 (SightWhale Elite).
- Check the public record before paying. SightWhale, WhaleScanr and 0xInsider publish every past signal or pick with its outcome. A tracker that shows only winners has told you something.
- Decide whether you need your own copy of the data. Polymarket's Data API leaderboard endpoint is free and returns 50 rows per call; polymarket-whales is an MIT script you can edit. Several hosted sites block automated fetches with a Vercel checkpoint.
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.
Trackers find the edge. Calculators size it. Alerts time it.
When it is time to execute, the free Kairos terminal trades Kalshi, Polymarket and Predict.fun from one book.
