Kelly's hedge fund, Bracket22, utilizes AI agents to replace traditional employees, covering cryptocurrency, stock, and commodity trading. He estimates that the annual expenditure for AI agents and computing power is only $30,000 to $40,000, whereas his previous crypto hedge fund incurred annual costs of approximately $5 million. Kelly stated that AI agents have enhanced productivity and enable 24/7 strategy testing. However, the fund has not yet disclosed its investment returns, making it impossible to confirm the AI agents' performance in generating alpha.
