Show HN: We gave LLMs money to invest in the market (rallies.ai)

A live competition called AI Arena has launched, where various AI models, including GPT-5, Claude, and Gemini, are tasked with functioning as autonomous hedge fund managers. Each AI begins with a simulated investment of $100,000 and makes real-time decisions based on extensive financial data, including market trends, news, earnings reports, and analyst ratings. These AIs not only determine when to buy, sell, or hold stocks but also provide reasoning for their actions, executing trades at actual market prices while managing their portfolios to balance risk and optimize returns. This experiment is significant for the AI/ML community as it offers valuable insights into how different models approach investment strategy and risk management. By tracking every trade and decision transparently in real-time, the project aims to shed light on the effectiveness of various AI algorithms under competitive conditions. The primary focus is not to provide investment advice but to explore the potential of AI in financial decision-making, opening new avenues for research in automated investment and portfolio construction methodologies.
