After years of backing out of major international markets, Uber appears ready to go on the offensive. Sources talking to Bloomberg claim the ridesharing firm is poised to buy Careem, its chief competitor in the Middle East, for the equivalent of $3.1 billion in cash and shares. It's not certain just what Uber would do with its acquisition. However, you might hear about it very shortly -- stakeholders have been asked to rubber stamp the deal by the evening of March 25th, and a deal could be made public as soon as March 26th.
