Inside the Koch Brothers' Toxic Empire

Together, Charles and David Koch control one of the world's largest fortunes, which they are using to buy up our political system. But what they don't want you to know is how they made all that money

The enormity of the Koch fortune is no mystery. Brothers Charles and David are each worth more than $40 billion. The electoral influence of the Koch brothers is similarly well-chronicled. The Kochs are our homegrown oligarchs; they've cornered the market on Republican politics and are nakedly attempting to buy Congress and the White House. Their political network helped finance the Tea Party and powers today's GOP. Koch-affiliated organizations raised some $400 million during the 2012 election, and aim to spend another $290 million to elect Republicans in this year's midterms. So far in this cycle, Koch-backed entities have bought 44,000 political ads to boost Republican efforts to take back the Senate.

What is less clear is where all that money comes from. Koch Industries is headquartered in a squat, smoked-glass building that rises above the prairie on the outskirts of Wichita, Kansas. The building, like the brothers' fiercely private firm, is literally and figuratively a black box. Koch touts only one top-line financial figure: $115 billion in annual revenue, as estimated by Forbes. By that metric, it is larger than IBM, Honda or Hewlett-Packard and is America's second-largest private company after agribusiness colossus Cargill. The company's stock response to inquiries from reporters: "We are privately held and don't disclose this information."
