Hyperliquid's well-known trader CBB shared that he and his two brothers have been running a stock and commodity perpetual contract arbitrage bot since October 2025, capturing price spreads and hedging between Hyperliquid HIP-3 and Interactive Brokers (IBKR). Over the past 10 months, the team has completed approximately $32 billion in trading volume, generating around $10 million in profit, with an annualized return on invested capital of about 35%–45%. CBB mentioned that the strategy initially focused on stock perpetual contracts but later expanded to markets like gold, silver, oil, and semiconductor stocks. However, with institutions like Wintermute entering the space and Ethena planning to participate in stock basis trading, the arbitrage opportunities have noticeably narrowed. The trading volume and profit figures mentioned above were self-reported by CBB. https://(wublock123.com)/news/hyperliquid-trader-cbb-hip-3-tradfi-arbitrage-10m-profit-67722
