Founded2001

Ronin Capital, LLC was a prominent proprietary trading firm headquartered in Chicago, specializing in derivatives, equities, and fixed income across global financial markets. Established in 2001, the firm was known for its advanced technology, quantitative trading strategies, and significant presence in electronic trading and market making. Ronin Capital faced severe financial distress following the 2011 collapse of MF Global, one of its key clearing firms, which restricted access to substantial funds. This ultimately led to Ronin Capital filing for Chapter 11 bankruptcy protection in February 2015 and subsequently winding down its operations.
