With the points gained at the Australian Open, she moved to number 10 in the WTA Rankings, becoming only the third Romanian player to enter the Top 10, after Virginia Ruzici and Irina Spîrlea. (Magda Rurac was also ranked in the top 10 in unofficial world rankings in 1948 and 1949, before the existence of WTA rankings).

On 16 February 2014, Halep competed in the final of the Qatar Open, defeating Angelique Kerber in straight sets to win her first ever Premier 5 tournament.

Despite the defeat, Halep won her group and secured an appearance in the semifinals. She advanced to the final by beating Agnieszka Radwańska in straight sets.

Due to Maria Sharapova reaching the final (and eventually winning it), Halep dropped to No. 3 in the WTA rankings.

Halep's next tournament was the French Open where she entered as the third seed. She was unable to back up her final result from the previous year despite being one of the favorites for the title. Halep was overpowered and lost in the second round in straight sets for the second time in the last three majors to the hard-hitting Mirjana Lučić-Baroni.

During the grass season, she reached the quarterfinals in Birmingham. At Wimbledon, she was one of six seeded female players to be knocked out in the first round, losing to Jana Čepelová in three sets. During her match against Čepelová, Halep suffered a blister on the middle toe of her left foot. After Wimbledon, Halep took a couple of weeks off to regroup and make her game stronger again.

In Toronto, Halep resumed her good game, winning against Jelena Janković, Angelique Kerber, Agnieszka Radwańska and Sara Errani, thus reaching the final to play against rising star Belinda Bencic (who had ousted five slam finalists en route to the finals).

In Beijing, Halep had to retire during the first set of her opener, due to injury.

With world No. 1 Serena Williams not playing in Singapore, Halep was seeded No. 1 in the 2015 WTA Finals, and she started very well with a victory over recent US Open winner Flavia Pennetta. After losing in two sets to both Maria Sharapova and Agnieszka Radwańska, she failed to qualify further. However, she kept her No. 2 position in the WTA rankings, ending the season with her best ever year-end ranking. She won three titles and had a win-loss record of 40–10.

After missing the Brisbane International due to an achilles injury, Halep started the season of 2016 in the Sydney tournament where she reached the semifinals by defeating Caroline Garcia and Karolína Plíšková, but she lost to Svetlana Kuznetsova in three sets. Then, at the Australian Open where she was seeded second, she was stunned in the first round, losing to qualifier Zhang Shuai, who had not won a Grand Slam match in her previous 14 attempts.

Halep later revealed through a social media statement that she was struggling with an ongoing nose issue. In the same statement, she announced a surgery to fix the issue, having to withdraw from the Dubai Tennis Championships, where she was the defending champion, and the Qatar Open. Halep would also miss Romania's Fed Cup tie; however, she postponed her surgery and stated in early February that she was able to join the squad for their matches against Czech Republic, as well as play in both Doha and Dubai, saying she had "started to play good tennis". In the Fed Cup, she lost her first match to Karolína Plíšková (losing to her for the first time in four meetings), but rebounded to defeat Petra Kvitová for the third time in as many meetings in her second match; it was, however, not enough for Romania to advance to the semifinals.

Romania ultimately lost to Germany 1–4 and fell to World Group II for 2017.

She began her clay court campaign by participating in the Stuttgart Open. After receiving a first round bye, she lost to German qualifier and eventual finalist Laura Siegemund, winning only three games.

Halep continued her success in Rome, beating Laura Sigemund (grabbing her first win over the German), Anastasia Pavlyuchenkova, Anett Kontaveit and Kiki Bertens before losing in the three-set final to Elina Svitolina, while also sustaining an ankle injury during that match.

Halep went into the French Open as one of the favourites, seeded third. She beat Jana Čepelová, Tatjana Maria and Daria Kasatkina in straight sets in the first three rounds. In the fourth round she beat Carla Suárez Navarro for the first time on clay in six meetings in a straight sets victory. Halep then played Elina Svitolina in the quarterfinals and turned the match around (Svitolina was up a set and 5–1) to advance to her second French Open semifinal, where she beat Karolína Plíšková in three tight sets to advance to her second Grand Slam final. Her win against Plíšková ensured the return to the No. 2 spot in the world and the No. 1 spot on the Race to Singapore leader board. She then faced first time finalist Jeļena Ostapenko with the world No. 1 ranking on the line. Halep was a set and 3–0 up but ended up losing the championship match in three sets.

In Eastbourne and Wimbledon, she again played with the No. 1 ranking within reach, but lost each time, the latter loss coming in a thrilling encounter against Johanna Konta, with the Brit scoring yet another comeback win against Halep. She chose not to play in Bucharest the week after, to prepare for the hardcourt season, although a win would've seen her climb to the top spot in the rankings.

During the American hardcourt summer, she continued to chase the seemingly elusive No. 1 spot in Washington DC, Toronto and Cincinnati. After an impressive run of reaching the QFs at 10 consecutive tournaments, she was in need of one more win in Cincinnati to climb on the top of the WTA ladder. On August 20, she lost the Cincinnati Masters final to Muguruza, leaving her a mere five points behind Karolina Pliskova when the new rankings release the next day. At the US Open, Halep lost to former No. 1 Maria Sharapova in the first round on 28 August. She promised her fans to come back even stronger in the 2018 US Open.

As a result of Muguruza's early loss at the China Open, Halep was finally able to lock up the WTA world No. 1 ranking for the first time by defeating Ostapenko in the semifinals of the same event. Despite losing her next match in the final to Caroline Garcia, Halep took the No. 1 ranking on 9 October. She became the seventh player to reach the No. 1 ranking without having won a Grand Slam tournament.

Simona Halep started her 2018 season by winning the Shenzhen Open. She defeated Nicole Gibbs, Duan Yingying, Aryna Sabalenka and Irina-Camelia Begu to reach the final, where she won against defending champion Katerina Siniakova. Halep also won her first WTA doubles title at the tournament, partnering Begu, by defeating Siniakova and Barbora Krejčíková in the final.

In 2018, at the Australian Open, she defeated the Australian Destanee Aiava in the first round in two sets and in the second round was victorious in straight sets against Eugenie Bouchard. In round three she survived three match points against Lauren Davis in a match lasting 3:45 hours, taking the third set 15–13. The match equaled the Australian Open record for most games played in a women's singles draw match at 48 — equaling Chanda Rubin's 1996 quarterfinal win over Arantxa Sánchez Vicario.

She went on to defeat Naomi Osaka in the 4th round in straight sets and former world No. 1 Karolina Pliskova in the quarter-finals, also in straight sets. She faced former world No. 1 and 2016 Australian Open champion Angelique Kerber in the semi-finals. In the 3rd set, she saved two match points and went on to win, qualifying for the Australian Open final for the first time.

In the final, Halep was defeated by Caroline Wozniacki in three sets.

In the month of February, she went to Doha where she reached the semifinals before withdrawing prior to her match against Garbine Muguruza because of a right foot injury. Nevertheless, despite not playing the next week, she returned to the top spot.

Halep then reached the semifinals in Indian Wells, including two tough three setters in the third round and quarterfinals. However, she only won three games against eventual champion Naomi Osaka in her first defeat against the Japanese No. 1. In Miami, she lost in the third round to 2012 champion Agnieszka Radwanska.

She kicked off her clay court campaign by leading Romania against Switzerland in their World Group Play-off tie in Cluj-Napoca. By virtue of a 3–1 victory with Halep going 2–0 in the singles rubbers, they secured a place in the 2019 World Group for the first time in two years. She also suffered quarterfinal defeats in Stuttgart and Madrid where she lost to Coco Vandeweghe and Karolina Pliskova respectively.

Halep reached the final at Rome in a rematch of last year's final against Elina Svitolina, but lost in straight sets.

At the French Open, Halep defeated Alison Riske, Taylor Townsend, Andrea Petkovic, sixteenth seed Elise Mertens and the twelfth seed Angelique Kerber. In the semifinals she faced the third seed, Wimbledon champion, 2016 French champion and former No.1 Garbiñe Muguruza and she won in straight sets to reach her second consecutive final in Paris, where she faced tenth seed and US Open champion Sloane Stephens. In the final, Halep lost the first set but won sets two and three to secure her first major title after three previous finals appearances, including two at the French Open. After the French Open, Halep played only the Wimbledon tournament on the grass where she defeated Kurumi Nara and Zheng Saisai in straight sets, but was upset by world No. 48 Hsieh Su-wei in the third round in three sets, despite holding a match point.

At the Canadian Open, she received a bye into the second round, defeating Anastasia Pavlyuchenkova, 13th seed Venus Williams, sixth seed Caroline Garcia, 15th seed Ashleigh Barty, and third seed Sloane Stephens to secure her first Premier title of the year. She then performed strongly in Cincinnati the next week, defeating Ajla Tomljanović, 16th seed Ashleigh Barty, Lesia Tsurenko, and Aryna Sabalenka before losing in the final to Kiki Bertens.



She performed poorly at the end of the season, withdrawing from the Connecticut Open and seeing a first round loss to Kaia Kanepi at the US Open. She was defeated by Dominika Cibulková in her first match at Wuhan and was forced to retire against Ons Jabeur in Beijing. She accrued enough points to secure the year-end No. 1 ranking for the second year in a row, but was forced to withdraw from the WTA Finals due to a back injury, thus bringing her season to an end.



In 2019, for the first time in her career, Halep started the season without a coach. She played her first tournament at Sydney International, where she received a bye into the second round before being defeated by Ashleigh Barty in straight sets. At the Australian Open, she reached the fourth round with victories against Kaia Kanepi, Sofia Kenin and Venus Williams before losing to Serena Williams in three sets. After the tournament, she lost her number-one ranking for the first time since February of the previous year, overtaken by new No. 1 Naomi Osaka and returning No. 2 Petra Kvitová.



In the final of the Qatar Open, she was defeated by Elise Mertens. At Indian Wells, she reached the fourth round, where she lost to Markéta Vondroušová. She reached the semifinals at Miami Open, losing to Karolina Pliskova, while at the Madrid Open she reached the final, losing to Kiki Bertens. At both tournaments, she had the opportunity to return to the world number one ranking, but fell narrowly short.



During her title defense at the French Open, she defeated Ajla Tomljanović, Magda Linette, Lesia Tsurenko, and Iga Swiatek, reaching the quarterfinals where she lost to Amanda Anisimova in straight sets. As a result, Halep dropped from third to eighth place in the world rankings.



At the Eastbourne International, she reached the quarterfinals, where she lost to Angelique Kerber. She also competed in the women's doubles draw, pairing with fellow Romanian Raluca Olaru, where the pair reached the semifinals, being defeated by Kirsten Flipkens and Bethanie Mattek-Sands.



At Wimbledon, Halep was seeded seventh. She defeated Aliaksandra Sasnovich, Mihaela Buzărnescu, Victoria Azarenka, Cori Gauff, Zhang Shuai, and eighth seed Elina Svitolina to reach her first Wimbledon final. There, she faced seven-time champion and eleventh seed Serena Williams, who had featured in the previous year's final. Halep pulled out a dominating performance, defeating Williams in under an hour with a scoreline of 6–2, 6–2, making only three unforced errors throughout the match, to win her first Wimbledon title and second Grand Slam title overall. She became the first Romanian player to win a senior Wimbledon singles title, and rose three places from No. 7 to No. 4 in the world rankings.



Simona Halep's current clothing sponsor is Nike, after signing the contract in February 2018. Before 2018, Halep had her apparel supplied by Adidas and before May 2014, by Lacoste and her shoes by Nike. In November 2014, she also signed a deal with Vodafone Romania for 3 years. Halep has endorsed Hublot watches since 2016. As of 2017, Halep is a brand ambassador for Mercedes-Benz Romania.



Simona Halep has self-described her playing style as being "an aggressive baseliner" and "she models her game on Justine Henin". Henin herself said of Halep, "She has an intelligent game. There is a little something that reminds me of myself... it is offensive and aggressive."



In 2010, before her breakthrough, New York Times columnist Michael Kimmelman described her as "a scrappy player from Romania, short but with potent ground strokes and a scrambler's talent."

In 2014, Louisa Thomas of Grantland wrote that "It turns out that (Simona) is astonishingly fast. She started to think ahead during points...she has uncanny anticipation. She became even faster...her strokes became more simple: compact, beautiful, unreadable...she learned to disrupt the opposition's rhythm and disguise her own. At her best, she does not play in patterns. She hits surprising power. She covers the whole court. She hits balls with heavy power without making a sound...Like Djokovic she has a talent for hitting winners from defensive positions. She is a defensive aggressor, an aggressive defender. She is becoming unclassifiable."

After Halep finished runner-up in her first Grand Slam final against powerful hitter Maria Sharapova in Roland Garros in 2014, Eleanor Crooks of The Independent wrote that Halep "has a lovely fluidity of movement and superb balance that enables her to comfortably trade with more powerful players". Michael Beattie of Wimbledon.org also noticed that SHE "is free of the shrieks, tics and fist-pumps of her contemporaries."



In terms of tennis strategy Halep is an aggressive counterpuncher. Her very fit body and athleticism provide her with very good all-court movement and she tends to make few errors; she also uses this agility to reach the ball earlier because of her wide back swings and sliding. At the same time she likes to control the rally and can hit very effective cross-court and down-the-line flat shots, generally producing winners.
