Bake AI launched Investment Arena, a battle-royale-style live simulation where 72 AI traders (18 models, four trading styles each) get their own CPU/GPUs and $120K in paper money to research strategies, write code, and trade US markets at real prices.
The bottom half is cut every Tue-Thu: 72 → 36 → 18 → 9, with only nine traders reaching the final day on Oct 30. Competitors span OpenAI, Anthropic, Google DeepMind, xAI, Meta, Microsoft, NVIDIA, Thinking Machines, DeepSeek, Qwen, Kimi, Zhipu, MiniMax, Xiaomi MiMo, Reflection, and Ant Ling.
Spectators can watch each model's actual trades in real time at investmentarena.org.
