Shark Radar vs Polyrank
Two skill boards fighting the same broken default. Different primary gates. Here's a fair contrast — no trash-talk, just what each product is for.
Same enemy
Both of us are fighting the same broken default: Polymarket (and most tools) rank P&L and win rate, which reward size and luck. If you already believe "profit ≠ skill," you're in the right category.
Where we diverge
Polyrank publicly centers calibration / Brier and a wide metric grid (skill vs P&L, calibration proof points on their site). That's a serious skill thesis.
Shark Radar centers a different product question: is this wallet worth listening to as a human researching markets — and did they just make a real decision? So we:
- Score ROI on risk (not headline dollars)
- Run a luck filter and uncopyable-style screen (MM, farming, structural edges)
- Label archetype / style on the board
- Alert on net position changes, not fill spam
Skill ranking isn't one number. Calibration and ROI-on-risk answer related but different questions. Details on how we score.
Quick comparison
| Polyrank | Shark Radar | |
|---|---|---|
| Thesis | Follow the skilled, not the lucky | Leaderboards rank luck; we rank skill |
| Core signal | Calibration (Brier), alpha-vs-mid, risk — large metric set | ROI on money actually risked + luck filter + archetype/uncopyable screen |
| Board job | Skill score vs P&L toggle; deep trader terminal | Live skill board + confidence + style |
| Alerts | Follow / real-time fills (their product) | One Telegram alert per real net position — research signal, not mirror |
| Custody | Read-only analytics | Read-only — no keys, no execution |
| Who it's for | Traders who want calibration microscopes / API | Traders who want a copyability-aware skill screen then watchlist alerts |
What we don't do
We don't run copy bots. We don't hold keys. Blind mirroring still fails on slippage — see the numbers on Polymarket copy trading: 0.035 persistence correlation; −13.6% OOS copy of top-15 PnL wallets; +$191k → −$64k at 2¢ worse fills.
Who should use which
Want a calibration microscope / metric builder / API-heavy terminal → evaluate Polyrank on their terms.
Want a skill-and-copyability screen + Telegram when they move → Shark Radar board.

Common questions
Is Shark Radar the same as Polyrank?
Same enemy — PnL luck — but different primary gates and UX. Shark Radar centers ROI-on-risk, an uncopyable-style filter, and net-position alerts. Polyrank publicly centers calibration / Brier and a wide metric grid.
Do you use Brier score?
Our public product language is ROI-on-risk, luck filter, archetypes, and confidence — not a Brier-first pitch.
Which is better for copy trading?
Neither should be treated as a blind-copy signal. We optimize for research alerts; see our Polymarket copy-trading page for the persistence and slippage numbers.
