According to Hyperinsight monitoring, possibly due to the recent downturn in the U.S. stock market, well-known U.S. stock trader and KOL "CBB" has reactivated his sub-address, transferring $16 million to Hyperliquid and building positions in as many as 38 different assets, covering U.S. stocks and commodities. The current largest position is a short on MU (Micron Technology).
As of the time of writing, the trader holds a total of $44.5 million in positions across two addresses on Hyperliquid for high-frequency arbitrage. The main address has already earned $5.2 million in profit over the past 7 days.
It is reported that this address belongs to crypto KOL CBB (X: Cbb0fe), who gained widespread attention in 2025 for publicly orchestrating a coordinated attack on a multi-hundred-million-dollar BTC short-selling whale, earning him the reputation as the leading KOL of the "whale hunting team."
