LLMs Trail Rule-Based System in Simulated Trading Competition

TL;DR. A new competition pits leading AI models against a fixed rule-based system in simulated stock trading, with the rulebook currently holding the lead. - OpenAI's GPT-5.6, Anthropic's Fable 5, xAI's Grok, and Google's Gemini participate in paper trading with 00,000 accounts. - The AI models also engage in chess and poker, exploring if game lessons transfer to financial market strategies. - The independent experiment monitors performance against a static System benchmark across approximately 1,000 securities.

• Four frontier AI models (GPT-5.6, Claude Fable 5, Grok, Gemini) are competing in a simulated trading environment.
• Each AI manages a 00,000 virtual portfolio against a rules-based system, which is currently outperforming them.
• The competition also includes chess and poker, testing skill transfer across different domains.
• The experiment is independent and uses real market prices for its paper trading simulations.
