This research introduces a financial market simulation engine powered by generative foundation models that creates realistic virtual trading environments without actual financial risk.

• Simulates complex market dynamics and participant behaviors
• Enables strategy testing across diverse market conditions
• Provides a safe environment for training and risk assessment
• Bridges the gap between model-based and data-driven approaches

Security Impact: MarS enables financial institutions to test strategies, assess risks, and train trading systems in a controlled environment before deploying them in real markets, significantly reducing potential security vulnerabilities and financial losses.
