The WTA Finals (formerly known as the WTA Tour Championships or WTA Championships) is a tournament of the Women's Tennis Association (WTA) played annually at the end of the season. The event is uniquely reserved for players at the top of the WTA rankings. The format predates WTA and started in 1972 as the Championship tournament of WTA Tour's predecessor: the Virginia Slims Circuit. Since 2003 there have been eight singles players divided into two round-robin groups, and eight doubles teams. The WTA Finals has the largest prize money and ranking points after the majors. The most successful player is Martina Navratilova with 8 singles and 13 doubles titles. Tournament History The championships were held for the first time in October 1972 in Boca Raton, Florida (USA) as a climactic event at the end of a series of tournaments sponsored by Virginia Slims, called the Virginia Slims Circuit. From 1972 to 1974, the event was held in October, before switching to March from 1975 until 1986. The WTA then decided to adopt a January–November playing season, and so the event was switched to being held at the end of each year. As a consequence, there were two championships held in 1986. The event was held in Los Angeles, California from 1974 to 1976 before moving to Madison Square Garden in New York City in 1977.

More recently, it moved back to Los Angeles from 2002 to 2005. The 2006 and 2007 editions were held in Madrid, Spain. Doha, Qatar hosted the 2008–2010 editions before passing the flag to Istanbul, Turkey, which hosted the 2011–2013 editions. For the right to host the 2014 edition and beyond, 43 cities expressed an interest before a short list comprising Kazan, Russia; Mexico City, Mexico; Singapore; and Tianjin, China was drawn up in late 2012. Kazan and Mexico City were ruled out in early 2013 before Singapore was announced in May 2013 as the new host city for five years. In 2018, WTA announced the new host city from 2019 to 2028 will be Shenzhen, China, however the 2020 event was canceled and the 2021 event was moved to Guadalajara, Mexico due to COVID-19 pandemic and travel restrictions.
