Brothers Use Claude to Net Nearly $10 Million in Hyperliquid-IBKR Arbitrage

Crypto arbitrage trader CBB and his brother turned to Anthropic’s Claude to overcome their limited knowledge of equities and traditional brokerage operations. They developed a market-neutral strategy targeting pricing gaps between stock perpetual contracts on Hyperliquid and offsetting positions at Interactive Brokers, or IBKR. The case illustrates how AI assistants can lower technical barriers to cross-market trading, while leaving traders exposed to execution, funding, liquidity and platform risks.

In a recent review of the strategy, CBB said the brothers used opposing positions on Hyperliquid and IBKR to hedge directional exposure and profit as the basis between the two markets converged. Over 10 months, the approach generated $32 billion in trading volume and nearly $10 million in profit. The scale underscores the opportunity created by fragmented pricing, though results depend on reliable hedging, sufficient liquidity and disciplined management of funding costs.
