On the final day of competition, she started off with a gold medal in the 50 metre freestyle with a time of 23.98 seconds. This marked her tenth gold medal won in individual events at FINA World Aquatics Championships, making her the fifth swimmer from any country to achieve the feat, after Michael Phelps of the United States, Katie Ledecky of the United States, Sun Yang of China, and Ryan Lochte of the United States, and the first swimmer representing Europe to achieve the feat. For her final event, she swam the freestyle leg in the 4×100 metre medley relay, helping team Sweden achieve a fourth-place finish in the event with a finals relay time of 3:55.96.

#### 2022 European Championships

Sjöström was one of twelve Swedish female swimmers named to the official roster for the 2022 European Aquatics Championships, held in August in Rome, Italy. On the second day of competition, she ranked first in the prelims heats of the 50 metre butterfly with a time of 25.30 seconds, qualifying for the semifinals later in the day. She lowered her time to a 25.10 in the semifinals and qualified for the final ranking first by over half a second. The following day, she won the gold medal with a time of 24.96 seconds. Her swim marked the fourteenth time she had swum the race faster than 25.00 seconds. Later in the session, she won a silver medal in the 4×100 metre freestyle relay, swimming a 53.12 for the lead-off leg of the relay in the final to help finish in 3:37.29.
In the morning session on day five, Sjöström started off ranking first in the prelims heats of the 50 metre freestyle with a 24.50, qualifying for the semifinals. For her second event of the session, she helped qualify the 4×100 metre mixed freestyle relay to the final ranking sixth, splitting a 54.28 for the fourth leg of the relay. With a 24.27 in the semifinals of the 50 metre freestyle, she qualified for the final ranking first, 0.09 seconds ahead of Katarzyna Wasick of Poland. Finishing off the day, she won bronze medal in the 4×100 metre mixed freestyle relay, splitting a 52.68 for the third leg of the relay to contribute to the final time, and Swedish record, of 3:23.40. The bronze medal marked her 26th medal at LEN European Aquatics Championships and set a new record for the most number of medals won at the Championships by a female swimmer from any country. She further increased the record to a total of 27 medals the following day when she won the gold medal in the 50 metre freestyle with a time of 23.91 seconds, this also marked a new overall record by a swimmer from any country, male or female. The previous record was set by male swimmer Alexander Popov of Russia at 26 medals.
The seventh and final morning, Sjöström split a 54.01 for the freestyle leg of the 4×100 metre medley relay, helping qualify for the final ranking first in 3:59.19. In the final, she lowered her split time to a 52.04, helping win the gold medal in a time of 3:55.25, which marked her 17th gold medal at LEN Aquatics Championships and extended the all-time total medal record to 28 medals.

### 2023

At the 2023 Stockholm Swim Open in April, Sjöström won the long course 50 metre freestyle with the fastest time in the world for the 2023 year by a female at that point in the time, a 2023 World Aquatics Championships qualifying time of 23.92 seconds.
At the 2023 World Aquatics Championships, Sjöström won the long course 50 metre freestyle, breaking her own world record in the semifinal. In doing so, she set the record for the longest period of time in between world-record setting performances by an individual swimmer, 14 years and 3 days after first breaking the 100 metre butterfly world record in 2009. She also won the 50 metre butterfly for the fifth time in a row at the World Aquatic Championships. These two medals led her to tie and then overtake Michael Phelps as the swimmer with the most individual World Aquatic Championship medals at 21 in her career. She additionally performed on Sweden's 400 metre freestyle and 400 metre medley relays; notably, her lead-off split of 52.24 in finals for the freestyle relay would have earned her a silver medal in the 100 metre freestyle.

### 2024
#### 2024 World Championships

At the 2024 World Aquatics Championships in Doha, Sjöström won the long course 50 metre freestyle as well as the 50 metre butterfly. The latter for a sixth time in a row at the World Aquatic Championships.

#### 2024 Olympic Games

Sjöström, now focusing on the shortest distances, had only planned to swim 50 metre freestyle at the Olympics. However, she decided to join 100 m freestyle as it suited her schedule between the 4×100m freestyle relay and the 50 metre freestyle. She first raced in the heats and the final of the 4x100m freestyle relay, where the Swedish team finished 5th in the final setting a new national record. She then went on to win the gold in 100 metre freestyle on 31 July with a time of 52.16 seconds. Despite being the World Record holder, Sjostrom had never won a gold medal in this distance at the global level. On the last day of competition she won another gold medal in the 50 metre freestyle, with a time of 23.71 seconds. She closed her Olympic Games with a 7th place finish in the 4x100m medley relay alongside her Swedish teammates.
