SightWhale watches the wallets it ranks in the top 1% of Polymarket by calibrated ROI and pushes a signal when one of them makes a large trade. Each signal carries a 0 to 100 conviction score built from win rate, trade size and context.

It is an alert service, not a leaderboard you browse. The differentiator it leads with is the record: every signal, win, loss or break-even, stays on a public history page.

What it does

Signals arrive in-app and, optionally, on Telegram about 30 seconds after the trade on Pro and about 10 seconds on Elite. The site says it tracks 500+ markets across politics, sports, crypto and other categories.

A free Volume-Weighted Analysis page needs no sign-up, and the History page shows the full signal table through the end of yesterday UTC without paying.

  • Pro: real-time in-app signals, 70+ Whale Score signals, a Fusion prediction score, per-signal breakdown, optional Telegram
  • Elite: everything in Pro plus 80+ high-conviction signals, full backtesting reports, market correlation analysis, Kelly position sizing, priority Telegram
  • Claimed extras: wallet clustering and deposit-address tracing

Pricing

Pro is $29 per month or $290 per year. Elite is $59 per month or $590 per year. Both cancel any time.

The refund term is unusual and worth quoting: if SightWhale is not profitable for you in your first month, email the operator and the subscription is refunded in full.

Venues and data

Polymarket only. Wallet selection is by calibrated ROI, which the site describes but does not publish as a formula.

Where it falls short

No Kalshi and no venue filter. Real-time signals are paid; the free tier is yesterday's table.

The signal count per tier is a marketing figure, and a high-conviction score is still the operator's model. Use the public history to check the hit rate before subscribing.

Who should use it

Traders who want to be pinged, not to browse, and who will hold SightWhale to its own published record.
