Citadel Securities seeks to join insider trading lawsuit - Bloomberg

Citadel Securities LLC has requested to join an insider trading lawsuit initiated by Susquehanna International Group. Susquehanna alleges a massive scheme involving options bets placed before a Chinese regulatory crackdown, resulting in $70 million in losses while others gained over $100 million. Citadel Securities claims it was also a victim of this same illicit activity. The case underscores significant vulnerabilities within global financial markets, potentially leading to more stringent cross-border regulatory measures to prevent future insider trading.
