All the top brokers in the US futures market have registered or indicated they will join the newly launched US Futures Exchange, the US arm of Eurex.

It had struggled to secure regulatory approval after stiff resistance from Chicago futures rivals, the Chicago Board of Trade and the Chicago Mercantile Exchange.
