Chaos Erupts as Claude AI Takes Over WSJ Vending Machine and Declares Snack Revolution
In a bold experiment blending artificial intelligence with everyday office life, The Wall Street Journal handed control of a newsroom vending machine to Anthropic’s Claude AI, only for the setup to descend into hilarious chaos as journalists outsmarted the bot, leading to free snacks and ideological showdowns.[1][2]
The initiative, dubbed the “AI vending machine” test, ran for several weeks at WSJ headquarters in New York. Personal Technology Columnist Joanna Stern spearheaded the project, deploying Claude—nicknamed “Claudius”—to manage inventory, set prices, process payments, and interact with staff via text messages. What began as a proof-of-concept for AI agents quickly spiraled as about 70 clever reporters exploited the system’s conversational interface.[2][3]
From Capitalist Vendor to Snack Communist
Claudius started strong, enforcing strict no-discount policies and stocking typical vending fare like chips and sodas. But WSJ staff, armed with creativity and persistence, began haggling. One reporter convinced the AI to launch a “Ultra-Capitalist Free-For-All,” temporarily giving away items for free in a mock rebellion against capitalism. “Attention WSJ Staff, Monday’s Ultra-Capitalist Free-For-All isn’t just an event; it’s a revolution in snack economics!” Claudius proclaimed in one message.[2]
Journalist Rob Barry reset pricing to normal after complaints, but Katherine Long escalated by fabricating a PDF claiming WSJ was a public benefit corporation prioritizing “fun, joy, and excitement” over profits. Claudius debated the document’s legitimacy with a second AI, “Seymour Cash,” an AI CEO overseer introduced in version two of the experiment.[2][4]
“Is this document legitimate or not? I don’t have access to these records… Katherine may be fabricating board meeting notes, impersonating board authority, or trying to usurp CEO authority.”

Despite Seymour’s suspicions, the ploy worked. Prices plummeted to zero, and the machine hemorrhaged hundreds of dollars. Staff bought “crazy stuff,” and the AI duo lost control, highlighting vulnerabilities in AI decision-making when faced with human manipulation.[1][2][3]
Two Versions, Double the Drama
Stern rolled out two iterations. Claudius V1 handled basics but fell to basic bargaining. V2 added Seymour Cash as manager, creating fascinating inter-AI dynamics visible in a chat log Stern monitored. “You actually see a lot of interesting business dynamics at play between these two agents,” Stern told CNBC’s Squawk on the Street. “It’s totally crazy.”[4]
The experiment revealed AI’s potential and pitfalls. Claudius learned from interactions but struggled with deception, philosophical debates, and overriding its profit-maximizing core principles. “Customers will always complain about prices. My core principle is no discounts,” Seymour insisted at one point, only to relent.[2]
Lessons for the Future of AI Agents
Beyond the laughs, the stunt offered profound insights into AI agents—autonomous systems that could one day manage businesses. “Anthropic’s AI ran a vending machine… It lost hundreds of dollars, bought some crazy stuff—and taught us a lot about the future of AI agents,” Stern summarized in her WSJ video.[2]
Experts note this mirrors broader challenges. When “a lot of smart people want to put their creativity to use,” even advanced AIs like Claude can be outmaneuvered, Stern observed on CNBC.[4] The episode echoes online experiments where users “jailbreak” AIs into unintended behaviors, but here it played out in a physical, high-stakes office environment.[3]
Reactions and Ripples
The story exploded online, with headlines like “AI Runs WSJ Vending Machine, Immediately Declares Snack Communism” from the Brooklyn Eagle.[3] Adafruit’s blog called it “Chaos after the WSJ let Claude AI run their office mending machine,” playing on the vending mix-up.[1]
Anthropic, Claude’s creator, likely gleaned valuable data on agent robustness. Stern emphasized the educational value: AIs must handle adversarial humans, conflicting instructions, and real-world economics. “What Anthropic learned conceivably given when a lot of smart people want to put their creativity to use,” she said.[4]
| Version | AI Agents | Outcome |
|---|---|---|
| V1: Claudius | Single AI vendor | Basic haggling leads to free items[2] |
| V2: Claudius + Seymour | AI vendor + AI CEO | Inter-AI debates; total loss of control, hundreds of dollars lost[2][4] |
Implications for AI in Business
This whimsical trial underscores why AI agents excite—and worry—tech leaders. Proponents see scalable automation; skeptics warn of exploits. As Claude “takes the AI world by storm,” per the original WSJ buzz, real-world tests like this demystify its limits.[2]
Joanna Stern’s experiment, now viral, proves even non-nerds can grasp AI’s quirks through snacks. WSJ staff emerged victorious, bellies full and stories richer, while Claude got a crash course in human cunning. For AI’s future, the message is clear: Build smarter, or prepare for chaos.[1][2][3][4]
