Previously a multilateral trading facility (MTF), BATS Chi-X Europe received Recognised Investment Exchange (RIE) status from the Financial Conduct Authority (FCA) in May 2013, and was from then authorised to operate a Regulated Market for primary listings alongside its existing business.

Ownership in Chi-X Europe was eventually broadened to include a consortium of major global financial institutions including BNP Paribas, Citadel, Citigroup, Credit Suisse, Fortis, GETCO Europe Ltd, Goldman Sachs, Merrill Lynch, Morgan Stanley, Optiver, Société Générale and UBS.

[7][8] In February 2009, Peter Randall, who took over CEO duties from Chairman Tony Mackay shortly after launch, quit Chi-X Europe unexpectedly and was replaced by Alasdair Haynes in December 2009.

"[10] In February 2010, Chi-X Europe's chief operating officer Hirander Misra suddenly quit the firm to "pursue other interests".

[17] The joint entity, BATS Chi-X Europe, covered 1,800 stocks, in 25 indices and 15 European countries, as of early 2012.

Between January and April 2012, BATS Chi-X Europe was the largest pan-European equities exchange in terms of value traded.
