Kenneth B. Dart (born 1955) is an American-born businessman and billionaire. Dart’s wealth has been estimated to be about at $6.6 billion (2013). Kenneth Dart is one of the heirs of William F. Dart, who founded the Dart Container Corporation (originally the Dart Manufacturing Company) in Michigan in 1937.
Kenneth Dart graduated from the University of Michigan with a degree in mechanical engineering in 1976. He joined the family business, the Dart Container Corporation, and became president of the company in 1986. His brother Robert Dart succeeded him in this role in 2001, when Kenneth Dart moved to the Board of Directors.
In the mid-90s Dart, his brother, Robert, and their tax lawyer, renounced their American citizenship, while the American citizenship of their families was not renounced. Kenneth Dart acquired the citizenship of, and a compound in, the Cayman Islands. He owns a number of Cayman-based enterprises, including Dart Enterprises, Dart Realty, and Cayman Shores Development. His Caymanian enterprises are estimated to own about 20-25% of the real estate in the Cayman Islands.
In 1994 Dart also became a citizen of Belize. At that time Dart offered his residence in Sarasota, Florida, to Belize as a consulate with himself as its consul. This would have allowed him to live in the United States full-time as a foreign diplomat avoiding any actions by the Internal Revenue Service; the State Department rejected the arrangement.
Kenneth Dart is on the Board of Directors of the Dart Foundation, a private family foundation established in 1984 by William A. and Claire T. Dart. The Dart Foundation’s mission is to advance and encourage youth education, primarily in the areas of science, technology, engineering and mathematics (STEM). The Dart Foundation and Kenneth Dart individually have supported the Dart Center for Journalism and Trauma, a project of Columbia University Graduate School of Journalism providing resources to journalists who cover violence, conflict and tragedy worldwide. 
Kenneth Dart and Dart Cayman Islands partnered with the Cayman Islands Government to design, build, restore and maintain five district parks and assist with the restoration and development of six additional public community parks in Grand Cayman. 
Along with his family, Ken Dart created the Minds Inspired High School Scholarship in 2012 and the Minds Inspired William A. Dart Memorial University Scholarship in 2013. The High School Scholarship aims to increase the quantity and quality of Caymanians pursuing mathematics and science related careers. The University Scholarship is available to eligible students with an interest in pursuing a Bachelor's Degree from an accredited overseas institution. 
Dart owns Dart Management, “one of the best known of the so-called vulture funds.” The strategy of vulture funds is to buy government debts at sharply reduced prices when weak governments are in crisis, and eventually force these governments to pay the full amount of the debt. Dart employed this strategy in 1994 by acquiring Brazilian debt instruments and eventually generating a profit of about $600m.
In the ongoing attempts to resolve the Argentinian financial crisis of 2001 Kenneth Dart (as well as Paul Singer) rejected Argentina's restructuring offer in contrast to most other investors and brought their claim to the US court system. In response to Dart's holdout strategy, the then Argentinian ambassador in the US, Jorge Argüello, rebuked Dart's activities, while in the Argentinian press Dart was named "Enemy Number One of Argentina". In 2012, a New York State judge ruled in favor of the holdout creditors ordering Argentina to pay $1.3 billion and Argentina's appeal of the ruling at the US Supreme Court was rejected in 2014. The US judicial rulings forced Argentina to miss bond payments in July 2014. This in turn caused Argentina to be declared in selective default by Standard & Poor's and in restrictive default by Fitch Ratings, meaning that Argentina failed to meet some of their obligations while meeting others.
