Singapore is now the ninth city to host the WTA Finals since its inauguration in 1972 and will host the event for at least five years.

Qualifying In singles, point totals are calculated by combining point totals from sixteen tournaments. Of these sixteen tournaments, a player's results from the four Grand Slam events, the four Premier Mandatory tournaments, and (for Top 20 players at the end of 2016) the best results from two Premier 5 tournaments must be included. In doubles, point totals are calculated by any combination of eleven tournaments throughout the year. Unlike in singles, this combination does not need to include results from the Grand Slams or Premier-level tournaments.

Format The singles event features eight players in a round robin event, split into two groups of four. Over the first four days of competition, each player meets the other three players in her group, with the top two in each group advancing to the semifinals. The first-placed player in one group meets the second-placed player in the other group, and vice versa. The winners of each semifinal meet in the championship match. The doubles event returns to a single elimination event. The winners of each quarterfinal match will advance to the semifinals and the winners of each semifinal match will advance to the final.

Round robin tie-breaking methods The final standings of each group were determined by the first of the following methods that applied: Greatest number of wins. Greatest number of matches played. Head-to-head results if only two players are tied, or if three players are tied then: a. If three players each have the same number of wins, a player having played less than all three matches is automatically eliminated and the player advancing to the single elimination competition is the winner of the match-up of the two remaining tied players. b. Highest percentage of sets won. c. Highest percentage of games won.

However, her next three tournaments were not as successful, retiring in the second round in Kuala Lumpur and suffering early exits in Indian Wells and Miami.

Svitolina began her clay court swing in Istanbul where she claimed the title, defeating Elise Mertens in the final. After a first round exit in Madrid, she rebounded to win another title, this time against Simona Halep in Rome. However, the next time she met the Romanian she did not have the same success, losing in the quarterfinals of the French Open despite having a match point in the second set. Svitolina struggled on the grass court of Birmingham, falling in the second round. This was followed up by a fourth-round loss to Jeļena Ostapenko at Wimbledon.
