Whale (specialist)

A whale — called a specialist on the Signals tab — is a high-P&L Polymarket wallet that SlipSignals tracks. In prediction markets, a “whale” is simply a trader large enough that their positions move money in a way worth watching. The label on its own means very little: size is easy to see and easy to fake significance with. What makes a whale trackable is a demonstrable record, which is why we separate every whale into proven and unproven.

Where the wallets come from

We pull tracked whales from Polymarket’s category leaderboards — politics, crypto, and similar — rather than the global board. The global leaderboard is dominated by sports bettors whose results rarely generalize to other categories, so a top-of-the-global-board wallet tells you little about who is sharp on, say, a regulatory or macro market. Category boards surface wallets with a focused, measurable edge.

A worked example

Suppose a wallet — blinded here as Specialist A4k — sits near the top of the politics category board with dozens of resolved bets. When A4k opens a fresh position on a specific market and outcome with real, non-trivial size, that single publicly-knowable fact becomes a signal. SlipSignals then scores it: how strong is A4k’s conviction, do other specialists already agree, and is there a live edge the market hasn’t priced away?

Critically, we never claim to know why A4k entered, what their private profit is, or whether they’ll be right this time. A whale tracker reports the knowable — a proven wallet put money into a specific outcome — and leaves the conclusion to you. That restraint is the difference between a signal and a recommendation.
