CME CME Group Inc

NYSE Euronext (NYX) will give itself until the end of the year to prove it can break CME Group Inc.'s (CME) hold on U.S. interest-rate futures trading, NYSE Liffe U.S. chief Tom Callahan told Reuters in an interview Tuesday.

The market exchange has attracted half a million rate-futures contracts over three months, and is on its way to capturing a million contracts, possibly in the next six months, Reuters reported Callahan as saying. CME has 41.4 million rate contracts at its clearinghouse.

"I can't think of another start-up exchange in its third month that has this level of open interest," Callahan told Reuters. "We have massive momentum. We've got a huge pipeline of customers...Our success and failure is going to be determined in the next six months."
