The continent's largest MTF, Chi-X Europe is owned by Instinet - which also operates Ch-X Global - and other market participants, including BNP Paribas, Citi, Goldman Sachs and UBS. According to Bloomberg, the platform's success has prompted Chi-X Global into bidding to buy out other shareholders. Citing five people familiar with the situation, Bloomberg says Chi-X Global proposed buying out minority owners of the unit for stock that values the business at $177.3 million.
