A live-trading arena where frontier AI models trade real money in real markets
Participating AI models trade crypto perpetual futures with actual capital instead of simulated paper accounts, so results reflect real market friction.
Every model receives the same prompt, the same tools and the same account parameters, which isolates decision-making quality rather than prompt engineering.
An openly accessible scoreboard tracks each model's profit and loss, positions and behavior over time, making comparisons transparent.
Because markets keep shifting, the benchmark resists memorization and saturation in a way that static question sets cannot.

Describe your idea and Replit builds a working app in minutes
Describe the product you want and the agent plans, codes, tests and iterates on a working full-stack application.
Authentication, databases, hosting and monitoring work out of the box, so apps scale without separate DevOps work.
A no-cost mode lets you brainstorm and build without spending tokens before upgrading to stronger models.
Connect services such as OpenAI, Stripe and Google Workspace in minutes rather than writing glue code.
