How to spot “WHALES & INSIDERS” using arkham

1 min readDec 22, 2025

Inspired by @0xMovez, I spent the last 60 minutes putting together a straightforward tutorial on how to find Whales and Insiders on @Polymarket.

No coding, no bots, no complex strategies. Just manual labor.

  • Step 1: Go to Arkham(https://intel.arkm.com) and search for the main Polymarket contract: “0x4bFb41d5B3570DeFd03C39a9A4D8dE6Bd8B8982E”
  • Step 2: Filter the Noise. Look at the live transactions list. Filter by value. The bigger the number, the bigger the whale.
  • Step 3: Pick a transaction you like, copy the wallet address.
  • Step 4: Search their address on https://polymarketanalytics.com and copy the handle of the wallet.
  • Step 5: Search their handle on Polymarket and explore their activity.

Here is the Alpha (How to spot the difference):

The Insider:

  • Usually has very few trades.
  • Bets BIG amounts on plays that look “strange” at first.
  • Look for New Creation Dates + Low Activity. That is your insider.

The Whale:

  • Just a high-conviction player with deep pockets and a huge risk appetite.

If you spot a fresh wallet dropping heavy size on a random outcome? Pay attention.

Always adjust your moves to your risk appetite.

Let me know how it goes.
