Largest Global Companies in the World 2018 - Richest Company Comparison

The largest companies in the world are getting bigger.
PwC Global Top 100 ranks companies by market capitalization: the greater the stock market value of a company, the higher its ranking. Values are calculated based on share prices as of March 31, 2018 multiplied by the number of shares. The market capitalization of the Global Top 100 firms has increased by 15% year-over-year.

It is certainly no surprise that the company standing at the top PwC Global Top 100 ranking is Apple. The company retains the pole position for the seventh year in a row. In PwC's list Apple’s market cap increased by 13%, although the gap with second-placed Alphabet decreased by 25%. PwC calculates values as of March 31, 2018 but Apple made history shortly thereafter: on August 2, 2018, it officially reached a market capitalization of $1 trillion, making it the first U.S. company to hit the milestone. Alphabet—as well as Microsoft and Amazon.comin third and fourth place respectively—may be next to follow in its footsteps.
While the top four companies remain unchanged compared to last year, there are two new entries in the top 10: Chinese technology companies Tencent and Alibaba, which replace US firms Exxon Mobil and Wells Fargo. US firms still dominate with 54 out of 100 companies, although down from 55 in the previous year. - gfmag.com
