The chairman and chief executive of Cboe Global Markets, which expanded this year by acquiring one of the world's biggest equities exchanges, has predicted more landmark deals ahead.

Cboe was borne out of the Chicago Board Options Exchange's $3.4bn takeover of Kansas-based Bats Global Markets in early March 2017, the same month that the European Commission blocked the €29bn merger of the London Stock Exchange and its German rival Deutsche Börse, which cast doubt on authorities' tolerance of major deals between exchanges.
