In a shocking move that's sending shockwaves through the financial world, Citadel, a Chicago-based hedge fund, has fired a warning shot at New York City after its founder, Ken Griffin, was publicly targeted by Citadel's CEO, Ken Griffin's former protégé, Nino Mamdani. Mamdani, who had previously risen through the ranks at Citadel, made scathing comments about Griffin in a recent interview, sparking a heated backlash from the billionaire investor. Now, Citadel is pushing back, warning the city of potential consequences if it continues to pursue a lawsuit against the firm. The high-stakes feud has implications for the future of big finance in the city, and could have far-reaching consequences for investors and businesses alike.
