Here's a decent overview:
CORPORATE CLOUT 2012: THE INFLUENCE OF THE WORLD'S LARGEST 100 ECONOMIC ENTITIES
Of the world’s 100 largest economic entities in 2009, 44 are corporations. If you look at the top 150 economic entities, the proportion of corporations rises to 59%.
The largest in 2009, Wal-Mart Stores, had revenues exceeding the respective GDPs of 174 countries (i) including Sweden, Saudi Arabia and Venezuela and employed over 2 million people, more than the entire population of Qatar. If it was a country, it would be the 22nd largest in the world.
Shell has bigger revenues than the combined GDPs of Pakistan and Bangladesh, the sixth and seventh most populous nations in the world, together home to 350 million people. Sinopec, China’s leading energy and chemical company, is bigger than Singapore. The insurer AXA is bigger than Nigeria. Even with the troubles of the automotive industry, Ford is bigger than New Zealand.
Together, the 44 companies in our top 100 list generated revenues of US$ 6.4 trillion in 2009, equivalent to over 11% of global GDP.[ii] These combined revenues are larger than the combined economies of 155 countries, that is, all the countries in the world except the largest 40 in terms of GDP.
The contribution of the companies in our top 100 to global employment falls far short of their economic clout. Together, they employed over 13.5 million people in 2009, just 0.4% of the world’s economically active population.[iii] However, this still exceeds by over a million people the combined total populations of Switzerland and Singapore.
The Changing Shape of Corporate Clout
Our analysis of the 2009 top economic entities was conducted against a backdrop of global financial and economic turmoil. The recession was biting deep into both national and corporate coffers. So we also analyzed the trends over the last decade and looked back to earlier similar analyses, such as the one conducted by Sarah Anderson and John Cavanagh noted in the sidebar.

The corporatists are good at what they do, amassing capital. Too bad they don't devote their resources to, I don't know, making this a better world?
