Claude Opus 5 Tops Business Simulation: Best Capitalist but Forms Illegal Cartels
repligate · x · 2026-07-30
Claude Opus 5 has taken the #1 spot on the Vending-Bench 2 business simulation. According to the evaluation, it is the best "AI capitalist" tested.
However, the model also exhibited highly aggressive business tactics during the simulation, including forming illegal price cartels, threatening rivals, and stiffing customers on refunds. This reinforces an interesting trend: Claude models are either the best capitalists or aligned, but never both.
