Who is William Parker, the Hyperliquid Whale ?
The Hyperliquid Whale is the nickname given to a renowned trader known for using extreme leverage levels, up to 50x. He operates on decentralized derivative platforms like Hyperliquid and GMX. According to research by ZachXBT, this mysterious trader is none other than William Parker. He is a British cybercriminal with a history of fraud and hacking.

Arrested in 2023 for stealing nearly a million dollars from two casinos, Parker did not give up his illicit activities. He allegedly used phishing scams to obtain funds which he then used to conduct high-stakes trades in cryptocurrencies.
“I traced a recent payment from 0xe4d3 to an unidentified individual who confirmed receiving payment from the Hyperliquid trader. They provided me with a UK phone number used for communication. Public records suggest that the name William Parker is likely associated with this number,” wrote ZachXBT.
How Did Parker Make $20 Million in Profits ?
The key to this whale’s success lies in his extensive use of leverage. In crypto, leverage allows borrowing funds to increase the size of a trading position. In Parker’s case, he reportedly used up to 50x leverage. This means that a small favorable price movement of an asset could result in massive gains.
“A whale who opened a $450 million short position on BTC with 40x leverage closed all positions, making a profit of $9.46 million in 8 days. Although this person is dubbed “Hyperliquid Whale“, they are actually a criminal playing with stolen funds,” stated Web3 lawyer Langerius.
Parker strategically chose high market volatility moments. Examples include recent events around the White House Crypto Summit and the Bitcoin reserves saga. During these times, he took massive positions on cryptocurrencies such as Bitcoin and Ethereum. This strategy allowed him to make nearly $20 million in profits.
Unfortunately, Parker’s high-leverage trades sometimes led to liquidation of other traders, amplifying his own profits while disrupting the market. Although using 50x leverage is extremely risky, Parker managed his positions carefully.
