Does PolyTrack cover Kalshi?+
No — PolyTrack is Polymarket-only as of our last review. PolySharks covers both Polymarket and Kalshi with cross-venue consensus pairing.
Can I get the same data PolyTrack provides for free?+
PolySharks ships a free tier (no signup) showing the top 50 traders, the largest recent positions, and cross-venue consensus signals. The official Polymarket leaderboard is also free for individual trader PnL on Polymarket. Some third-party tools gate equivalent features behind subscriptions.
What metrics does PolySharks track that PolyTrack doesn't?+
PolySharks ships category landing pages at /bets/{politics,sports,crypto,finance} and /whales/{...} that are SEO-indexed per category, a free embed widget for newsletters, a documented public REST API ($39 Starter / $69 Pro tiers), and an auditable methodology page. The full feature matrix is in the comparison table on this page.
Where does PolySharks get its data?+
Public on-chain trade data from the Polygon blockchain (for Polymarket) and Kalshi's public API. We do not custody funds, do not execute trades, and have no privileged access. Methodology including known biases is published at /methodology.
