Blockchain analyst ZachXBT has claimed that a trader who recently generated $20 million on HyperLiquid through leveraged trading is likely to be William Parker.
Parker is a convicted fraudster known for his involvement in hacking and gambling-related offenses.
In a comprehensive thread on X, ZachXBT detailed how an on-chain investigation linked the whale’s transactions back to Parker.
The trader reportedly engaged in highly leveraged positions on HyperLiquid and GMX between January and March 2025, including a 50x long position on ETH and BTC just before Trump’s crypto reserve announcement, along with a 40x short on BTC, amassing nearly $20 million in gains.
The investigation pinpointed major platforms such as Binance, Roobet, and Alphapo as key counterparties connected to the activities. A wallet linked to the trader was also found to have received funds from a phishing scam and a hacked casino game.
Further examination connected these activities to Parker, who was arrested in Finland in 2023 for embezzling $1 million from casinos.
Parker, previously known as Alistair Packover, has faced fraud charges dating back to the early 2010s in the UK.
Despite having served time, ZachXBT indicated that Parker appears to have continued his illicit ventures, with most of his cryptocurrency assets now held in a traceable wallet.
