The tournament was run by the Women's Tennis Association (WTA) as part of the 2017 WTA Tour. 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:
 * 1) Greatest number of wins.
 * 2) Greatest number of matches played.
 * 3) 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.

Prize money and points
The total prize money for the BNP Paribas 2017 WTA Finals was US$7,000,000.

Singles

 * On 11 September, Garbiñe Muguruza became the first qualifier.

Garbiñe Muguruza began her season in Brisbane, where she retired in the semifinals. She recovered from this injury to reach the quarterfinals at the Australian Open, losing to CoCo Vandeweghe in straight sets. She had early exits in the Middle East before making the quarterfinals in Indian Wells and the fourth round in Miami, falling to Karolína Plíšková and retiring against Caroline Wozniacki respectively.

Muguruza's clay court season started slowly, losing her opening matches in Stuttgart and Madrid. She found form in Rome, reaching the semifinals, but failed to defend her French Open crown, ousted in the fourth round by Kristina Mladenovic. Muguruza opened her grass court season in Birmingham where she lost to Ashleigh Barty in the semifinals. She followed this up with a first round loss in Eastbourne to Barbora Strýcová, only managing to win one game. However, this slump was short-lived as her next tournament was a success, defeating Venus Williams in the final at Wimbledon, capturing her second major.

Muguruza kept up the good form on the American hard courts, making the semifinals in Stanford and the quarterfinals in Toronto. She then claimed her second title of the year, comprehensively beating Simona Halep in the final of Cincinnati, the last of three top-10 victories that week. However, she was unable to continue this string of deep runs, falling to Petra Kvitová in the fourth round of the US Open. Despite the relatively early exit, at the completion of this tournament, Muguruza took over the spot of World No.1 for the first time in her career.

Muguruza opened her Asian hard-court swing in Tokyo, losing in the semifinals to Caroline Wozniacki. The following week in Wuhan, she fell to Jeļena Ostapenko in the quarterfinals. Her last tournament before the WTA Finals was in Beijing where she retired in the first round, marking her fourth retirement this season.


 * On 26 September, Simona Halep, Karolína Plíšková, Elina Svitolina and Venus Williams became the second, third, fourth and fifth qualifiers.

Simona Halep comes into the WTA finals as the current World No.1 after a rather consistent year. Despite this, she began her year quite poorly, only managing three wins in her first four tournaments. A second-round loss in Shenzhen was followed up by a straight sets defeat in her opening match at the Australian Open to Shelby Rogers. She then retired in the quarterfinals of St. Petersburg before Kristina Mladenovic beat her in the third round in Indian Wells. She then reached the quarterfinals in Miami, losing to Johanna Konta.

Halep began to put in impressive results in the clay court season, starting with a semifinal showing in Stuttgart. She followed this up with her first title of the season in Madrid, winning in three sets over Kristina Mladenovic. She made another final the following week in Rome, but failed to overcome Elina Svitolina. She continued her string of reaching finals, this time at the French Open. However, she was again unsuccessful in taking home the trophy, losing to Jeļena Ostapenko.

Halep's first tournament on grass was in Eastbourne, which ended with a loss to Caroline Wozniacki in the quarterfinals. She also lost at the quarterfinal stage at Wimbledon, at the hands of Johanna Konta. After a retirement on the hard courts of Washington, Halep's results on this surface began to pick up. Reaching the semifinals of Toronto and the final of Cincinnati, losing to Elina Svitolina and Garbiñe Muguruza respectively. However, she drew Maria Sharapova in the first round of the US Open and suffered a three-set loss. She then lost her opening match in Wuhan. The following week, she reached the final in Beijing, losing to Caroline Garcia. Despite the loss, due to beating Jeļena Ostapenko in the semifinals, Halep became World No.1 for the first time.

Karolína Plíšková began her season with a strong showing in Brisbane, winning the title by defeating Alizé Cornet in the final. She followed this up with a quarterfinal showing at the Australian Open, losing in three sets to Mirjana Lučić-Baroni. Plíšková very quickly got back on the winner's board, claiming the title in Doha with a win over Caroline Wozniacki in the final. However, the following week she lost her opening match in Dubai. She had consistent results in Indian Wells and Miami, losing in the semifinals of both tournaments to Svetlana Kuznetsova and Caroline Wozniacki respectively.

Plíšková got off on the wrong foot in the clay court season, exiting early in Stuttgart, Prague and Madrid. She did manage to find some form at the following tournaments, with a quarterfinal finish in Rome and a semifinal finish at the French Open. She looked back on top of her game when the grass court swing came around, winning the title in Eastbourne over Caroline Wozniacki. However, it quickly came to an end with a shock loss to Magdaléna Rybáriková in the second round of Wimbledon. Despite the early exit, Plíšková earned the position of World No.1 for the first time in her career.

Next up for Plíšková were the American hard courts, where she had strong results. Losses to Caroline Wozniacki in the quarterfinals of Toronto and the semifinals of Cincinnati to Garbiñe Muguruza preceded the US Open where she fell in the quarterfinals to CoCo Vandeweghe. She then entered Tokyo and Wuhan, reaching the quarterfinals at both tournaments before losing to Angelique Kerber and Ashleigh Barty respectively. This was followed by a third-round loss in Beijing.

Elina Svitolina had an impressive year, putting together the best season of her career which included a tour-leading five titles. She opened her season in Brisbane with a semifinal loss to eventual champion Karolína Plíšková. At the Australian Open, she fell in three sets to Anastasia Pavlyuchenkova in the third round. Her next two tournaments ended with a trophy, defeating Peng Shuai in the final of Taipei, before coming away victorious in Dubai against Caroline Wozniacki. 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.

Getting back on hard courts, Svitolina wasted no time picking up another title, defeating Caroline Wozniacki in the final of Toronto. She couldn't find the same form in Cincinnati, falling in the third round. At the US Open, she reached the fourth round before losing to eventual finalist Madison Keys. A quarterfinal loss to Caroline Garcia in Beijing followed, and in her most recent tournament in Hong Kong, she withdrew before her second-round match.

Venus Williams had quite a resurgent season. After withdrawing from her second-round match in Auckland, she made it all the way to the final of the Australian Open, her first major final in eight years. However, she lost to sister Serena in the final. Her next tournament ended quickly, losing her opening match in St. Petersburg to eventual winner Kristina Mladenovic. Williams returned to form for the Sunshine swing, falling to Elena Vesnina in Indian Wells and Johanna Konta in Miami, both of whom went on to claim the title.

Williams suffered an early exit at her first clay court tournament of the year in Charleston. She put in better performances in her next two tournaments, losing to Garbiñe Muguruza in the quarterfinals of Madrid, before falling in the fourth round of the French Open against Timea Bacsinszky. She then proved she didn't need and warm-up grass court tournaments before Wimbledon, progressing to the final. This makes her the only player to reach two major finals this season. She was unable to claim the title however, falling in straight sets to Garbiñe Muguruza.

The American hard-court swing didn't get off to a good start for Williams, as she fell to Elina Svitolina and Ashleigh Barty in the third round of Toronto and the second round of Cincinnati respectively. She managed to turn things around at the US Open, reaching the semifinal stage before being defeated by Sloane Stephens. In her only tournament of the Asian swing, Williams lost in the second round of Hong Kong to Naomi Osaka.


 * On 30 September, Caroline Wozniacki became the sixth qualifier for the tournament.

Caroline Wozniacki had an extremely consistent season, proven by her tour-leading seven finals. Her first two tournaments were in Auckland and Sydney, where she reached the quarterfinals of both. At the Australian Open, she made it to the third round before a straights loss to Johanna Konta. Wozniacki then made back-to-back finals in the Middle East, falling to Karolína Plíšková in Doha and Elina Svitolina in Dubai. Her solid form stayed with her in Indian Wells and Miami, losing in the quarterfinals of the former to Kristina Mladenovic before making her first Premier Mandatory final in four years at the later. However, she lost to Johanna Konta.

Wozniacki started the grass court swing with good form. She reached the final in Eastbourne, but ultimately lost the title-match to Karolína Plíšková. Despite the positive result, she was unable to progress as far at Wimbledon, bowing out in the fourth round after losing in straight sets to CoCo Vandeweghe. Following this, Wozniacki returned to the clay courts, this time in Båstad where she lost in the final to Kateřina Siniaková. Wozniacki made another final at her next tournament in Toronto.

However, she could not manage a similar result in the final, losing to Elina Svitolina to mark her sixth straight loss in finals this season.

Wozniacki finally broke through in Tokyo, defeating Anastasia Pavlyuchenkova in the final to claim her first title of the season. However, this did not set up good results for the rest of the season, losing her opening match in Wuhan, falling to Petra Kvitová in the third round of Beijing and withdrawing before her second-round match in Hong Kong.


 * On 4 October, Jeļena Ostapenko became the seventh qualifier for the tournament.

Jeļena Ostapenko began her season in Auckland, where she retired during her semifinal match. At the Australian Open, she was ousted by Karolína Plíšková in the third round.

They took their first joint title in Indian Wells. The duo also played well in the clay court season, taking the Madrid Open and defending the Italian Open. Their clay court winning streak ended in the final of the French Open. They continued their triumphant performance in the grass court season, winning two titles in a row (Mallorca and Eastbourne), but reaching the quarterfinals of Wimbledon. The duo triumphed in Cincinnati, after Hingis failed to do so with Mirza in the 2016 season. Following that, the duo won three major titles in a row, US Open, Wuhan Open and China Open, staying unbeaten to date. Hingis became the new No. 1 doubles player and Chan joined her at No.1 before the finals.

Makarova and Vesnina are the defending champions. For both players, it will be their third appearance in the Finals.


 * On 13 September, Ashleigh Barty and Casey Dellacqua became the third qualifiers.

The team of Ashleigh Barty and Casey Dellacqua was one of the most strongest in 2013, who was not far away from qualifying for the four-teams Tour Championships. Since 2015, Barty partnered with other players and played mainly in the ITF tour, while Dellacqua had some success with Yaroslava Shvedova in 2015, but had to withdraw from the WTA Finals as she incurred a concussion in Beijing. In 2017, the Australians reunited and played together throughout the season. Their first success came at the Australian Open, reaching the quarterfinals. They won their first joint tournament, the Malaysian Open, but played poorly in Indian Wells and Miami.

Peschke had a strong partnership with Katarina Srebotnik before that. In the 2017 season, the pair did not play well until May, when they won the International Prague Open, their only title this year. They had less success in the clay and grass court season, but they managed to reach the semifinals in Wimbledon. They also reached the final in the following Rogers Cup. In the late season, the German-Czech duo's best result was reaching the quarterfinals of the Wuhan Open.

This is Grönefeld's first appearance at the Finals. For Peschke, it will be her seventh appearance at the Finals.

Gabriela Dabrowski and Xu Yifan debuted as a team in Miami, surprisingly beating top players such as Makarova/Vesnina, Hlaváčková/Peng and Mirza/Strýcová on their way before claiming their first title. They won another title in New Haven, beating Barty/Dellacqua in the final. Their best Grand Slam performance came at the US Open, where they reached the quarterfinals. In the Asian swing, they had moderate success, reaching the quarterfinals in Wuhan and Beijing.

For both players, it will be their debut appearance at the Finals.

They improved somewhat in late summer, achieving one of their best results this year by fighting through the quarterfinals of the US Open. This was followed by a triumph at the Tokyo Pan Pacific Open and a quarterfinal entry at the China Open.

For Klepač, it will be her debut at the Finals. Martínez Sánchez once appeared in the Tour Championships and won it with Nuria Llagostera Vives in 2009.


 * On 18 October, Kiki Bertens and Johanna Larsson became the eighth and last team to qualify.

Kiki Bertens and Johanna Larsson have regularly partnered together since 2015. In the 2017 season, they claimed their first trophy in the ASB Classic. Overall, Bertens and Larsson were mainly successful in low rank tournaments, having won three more titles. Beside that, they reached the quarterfinals at the Mutua Madrid Open. They twice reached the 4th Round at the French Open and US Open.

For both players, it will be their debut at the Finals.

Singles
The 2017 edition of the year–end finals will feature the current world No. 1, three major champions and three major finalists. The competitors were divided into two groups, representing the colors of the flag of Singapore.

Points breakdown
WTA players qualify for the WTA Finals by competing throughout the year in WTA tournaments throughout the world, as well as the four Grand Slam events. Players earn ranking points on the Porsche Race To Singapore leaderboard, and the top 7 singles players (and usually top 8) and top 8 doubles teams on this leaderboard at the conclusion of the year (as of the Monday following the final regular season tournament) earn the right to compete in the WTA Championships.

For singles, all results from that year count towards a player's ranking; for doubles, only the best 11 results for a team from that year count towards the team's ranking. The eighth spot in singles is not guaranteed a place in the finals as the WTA has some leeway per the WTA rules.

Singles
Players in gold have qualified. Players in brown have withdrawn from consideration from playing the tournament.

† The player's ranking at the time did not qualify her to play this event. Accordingly, the player's next best result is counted in its place.

‡ The player was not a Top 20 player at the end of 2016 and therefore not required to count her two best Premier 5 results. Accordingly, the player's next best result is counted in its place.

Doubles
Teams in gold have qualified. Teams in brown have withdrawn from consideration from playing the tournament even if they qualify. Teams in dark gold withdrew after qualifying. Teams in dark brown have one player that qualified separately with another partner, making the team ineligible to qualify.
