The Koch Network — $120B+ Combined

The Koch network's $120B+ combined wealth has been wielded with unmatched political precision, funding a $400 million campaign from 2008 to 2016 to reshape U.S. climate and labor policy. Their influence operations outspent the Walton family's lobbying by nearly 3 to 1 during peak years, moving the Republican Party's tax and regulatory agenda measurably rightward. The network's dark-money infrastructure has been called the most efficient political donor machine in modern history, spending roughly $75 million per election cycle to block environmental legislation, with a return on investment estimated at $1.2 billion in tax savings from the 2017 Tax Cuts and Jobs Act alone.
