Case files // The Whale Files · Subject: the most famous wallets on Polymarket

We X-rayed the most famous wallets on Polymarket.

Every trade on Polymarket settles on a public ledger. That means every legend has a record — and the record has a pattern. We ran the Trader X-Ray on three of the most talked-about wallets in prediction-market history, straight from the public on-chain record. No interviews. No spin. Just what they actually did with their money.

The files — three legends, read from the ledger

Exhibit A · Polymarket · Public wallet

Fredi9999 — the French “Trump whale”

The Diamond Hand

“Never sells. Sometimes that’s discipline; sometimes it’s denial.”

$16.6Mlifetime P/L
$76.6Mlifetime volume
45markets traded
100thP/L percentile

The single most press-covered bet in Polymarket history — the 2024 election position Forbes traced to one French trader across multiple accounts. This account alone: forty-five markets, almost all of it one conviction. The engine: politics, +83% ROI.

The Specialist

“One category pays the bills; the rest is entertainment.”

$3.3Mlifetime P/L
$484Mlifetime volume
9,716markets traded
100thP/L percentile

Nearly half a billion dollars of volume across almost ten thousand markets since 2022 — the most prolific record we’ve ever scanned. Community trackers attribute this wallet to the trader known as Domer, famous for early election calls. The X-Ray’s read is blunt: a genuine specialist whose one strong category carries everything else.

Went 5-for-5 on Super Bowl LX for a reported $1.8M single day. The record reads like a machine: thousands of markets, relentless sizing, and positions held to resolution. Suspected algo — the X-Ray doesn’t care. The ledger is the ledger.
