Whale Tracking 101: Reading the Smart Money on Polymarket

Why Whales Matter

On prediction markets like Polymarket, a "whale" is anyone with a position over $50,000. These aren't random gamblers — they're informed traders with skin in the game.

When multiple whales converge on the same side of a market, it signals something. Maybe they have inside information. Maybe they've done extensive research. Either way, following the money is a better strategy than following opinions.

How Penelope Tracks Whales

The MiroFish engine scans Polymarket's order book and position data to identify:

1. Individual whale positions — Any single position over $50k
2. Whale count — How many unique whales are on each side
3. Combined position — Total capital deployed by whales on a side
4. Position timing — When whales entered (early conviction vs. late bandwagon)

Reading the Signals

Here's how to interpret whale data:

| Whale Count | Combined Position | Signal Strength | |---|---|---| | 1 whale | < $200k | Weak — could be one rich gambler | | 2 whales | $200k - $500k | Moderate — worth watching | | 3+ whales | $500k+ | Strong — smart money alignment | | 5+ whales | $1M+ | Very strong — high conviction consensus |

The MiroFish Score

Whale data alone isn't enough. MiroFish combines it with:

• Historical pattern matching — How often does this whale count + category pattern win?
• Time to expiry — Signals are stronger when markets resolve within 14 days
• Market category — Some categories (sports, crypto) have more reliable whale signals than others

The final MiroFish score ranges from 0-100:

• 75+ = GO (take the trade)
• 65-74 = LEAN GO (smaller position)
• Below 65 = HOLD (skip)

Common Mistakes

1. Following a single whale — One position, no matter how large, isn't consensus
2. Ignoring the other side — If whales are split, it's a coin flip
3. Chasing after the move — If the price already reflects whale activity, you're late
4. Overweighting recent wins — Streak management matters. De-risk after losses.
