Correction: Story corrects in 8th paragraph to cite Kyodo News Service report that Softbank had agreed to buy Deutsche Telekom. Adds company denial.
NEW YORK (TheStreet) -- Even before it goes public, Alibaba is the biggest business story of 2014.
Most investors know the Yahoo! (YHOO) side of the story. Yahoo!'s stock is seen as a proxy for Alibaba itself. CEO Marissa Mayer has been able to purchase almost 40 other companies since her appointment in July 2012 thanks to the $1 billion investment her predecessors made in the Chinese e-commerce site in 2005.
But this pales next to Masayoshi Son's Alibaba-driven plans for global domination, based on an early investment of $20 million in the company, which was then merely a business-to-business site.
That stake was said to be worth $58 billion a few months ago and may soon be worth even more. It is fueling Son's ambition to do to this country's mobile business what he previously did to Japan's: Take it over.
A decade ago Japan's mobile market was a cozy duopoly between carriers descended from old phone companies, Nippon Telegraph and Telephone (NTT) and KDD. Then Son's SoftBank bought Vodafone Japan, slapped the SoftBank name on it, invested aggressively and it now has nearly one-third of the market, according to Eurotechnology.com.
At nearly the same time Sprint gobbled-up Clearwire, adding to its spectrum holdings.
The Tokyo-based Kyodo News Service reported Thursday that Softbank had agreed to buy Deutsche Telekom's stake in T-Mobile US (TMUS). A Softbank spokesperson on Friday denied the Kyodo report, and said the company could not confirm any deal.
T-Mobile's earlier acquisition of Metro PCS gave it an estimated 13% of the U.S. mobile market, according to Bluefield Strategies, against Sprint's 17%.
Put Sprint and T-Mobile together and the market becomes a closely-contested three-way race with Verizon (VZ) and AT&T (T). When it's not subsidizing the purchase of new Apple (AAPL) iPhones, AT&T can achieve operating margins well north of 25%, notes Bluefield Strategies.
