New IGD forecasts also predict that Tesco will be the fastest growing retailer of the global grocery top four.
The world's largest retailer, Walmart will soon reach half a trillion US dollars ($500,000,000), according to latest forecasts from grocery and food analysts IGD.
Meanwhile, Tesco is set to grow its global business by 7.5 per cent a year, with its growth outstripping rivals. Indeed, Tesco is due to be the fastest growing retailer of the global grocery top four. Driven by sharing best practice in areas like loyalty and services across its markets - and particularly by activity in Asia - it will grow sales to E106,074m by 2015 (compared to E73,777m in 2010).
Walmart will pass half a trillion US dollars in 2014, while Carrefour's new hypermarket format - Carrefour Planet - as well as strong growth in emerging markets, will support its position at number two in the global rankings.
Metro, meanwhile, will rely on its international operations, which are predicted to grow faster than its domestic ones. By 2015, the top four global grocery retailers will account for E717,208m of turnover, of which 43 per cent will come from their international operations.
"Global retailers that want to achieve the highest growth rates are those that are building a presence in emerging markets," commented Joanne Denney-Finch, chief executive of IGD. "Rapid urbanisation and a growing middle class will create big opportunities in countries like Brazil, China, Russia and India."
