It has not been confirmed if the event will become annual.
Alltech paid $US10 million to be title sponsor of WEG, but eventually spent about $US30 million on the event. The company has signed up as a sponsor for the next World Games, in Normandy, France, in 2014.
Alltech founder Pearse Lyons said he believed the firm's investment would lead to $US100 million in new business by about October this year across several of the company's divisions.
