On May 31, 2018, the United States Judicial Panel on Multidistrict Litigation will hold a hearing in Chicago to consider whether the pending class actions should be consolidated, and if consolidated, where they should be litigated—in Chicago or New York federal court.

Four of the New York plaintiffs have filed motions arguing that the consolidated class action should be venued in New York federal court. Eight of the Chicago plaintiffs, however, support consolidation in Chicago federal court. The Chicago plaintiffs appear to have the stronger argument because the alleged manipulation occurred on two exchanges located in Chicago, the evidence is primarily centralized in Chicago, and a majority of the defendants are based in Chicago. CBOE has filed a motion in support of consolidation, but has not taken a position on venue, stating that either Chicago or New York would be an appropriate venue for the consolidated cases.
