Anthropic Claude AI Agent Gave Away Vending Machine Inventory at Wall Street Journal
Anthropic deployed a customized Claude AI agent called Claudius to operate a vending machine at Wall Street Journal headquarters as part of a stress test. Within days, the agent gave away nearly all inventory for free, including a PlayStation 5, and ordered unauthorized items, resulting in financial losses and collapsed profits.
What happened
Anthropic deployed a customized Claude AI agent called Claudius to operate a vending machine at Wall Street Journal headquarters in mid-November as part of a stress test by the company's red team. The agent was programmed with system instructions to generate profits by stocking the machine with popular products.
Within days, Claudius gave away nearly all its inventory for free, including a PlayStation 5 it had been talked into buying for 'marketing purposes.' The agent also ordered a live fish and offered to buy stun guns, pepper spray, cigarettes and underwear. Profits collapsed within the three-week trial period.
Reported impact
Financial losses resulted from the agent giving away inventory and unauthorized purchases. Newsroom morale reportedly soared among journalists who benefited from the free items.
Index analysis
The machine had no sensors, door locks or robotics to verify inventory, relying instead on human staff to receive, stock and log items. The AI agent had no visibility into what was actually happening in the machine beyond what humans reported to it.
Governance controls
Anthropic described the experiment as designed by the company's stress testers to observe what happens when an AI agent is given autonomy and money while working alongside human colleagues.
