According to MLM monitoring data, a Bitcoin whale closed 90% of their BTC short positions and completely closed all ETH short positions on Hyperliquid, generating profits of approximately $190-200 million in just one day. Notably, this whale established nine-figure BTC and ETH short positions just minutes before the market decline. These represent only the whale's public positions on Hyperliquid, as their operations on centralized exchanges or other platforms remain unknown. This account may have played a crucial role in the day's market movements.
