Brynäs IF

Markström signed a two-year contract with the Brynäs IF senior team on 12 May 2008.^[1] He had previously been playing for the Brynäs IF junior team. The following month, after solid performances in the Swedish Hockey League and internationally for Sweden in the Under 18 and World Junior tournaments, the butterfly style goaltender^[2] was selected 31st overall in the 2008 NHL Entry Draft as the first choice of the Florida Panthers.

In 2009–10, Markström led the Elitserien in the save percentage (SVS%) and goals against average (GAA) statistics, with 92.72% and 2.01 respectively.^[3] On 1 June 2010, it was announced that the Panthers and Markström had agreed to terms on an entry-level contract.^[4]

Florida Panthers

On 23 January 2011, Markström made his NHL debut at the Prudential Center in Newark when he replaced starter Scott Clemmensen at the start of the second period in a loss against the New Jersey Devils.^[5] Upon his debut, he became the youngest goaltender to ever play for the Panthers.

Markström was then sent back to Florida's AHL affiliate team, the Rochester Americans. The team directives argued that Markström needed to get used to hockey in North America since players had different shooting tendencies. The goaltender struggled during his first season in the AHL and also injured his knee. After surgery in South Florida, Markström worked to get back in the game, hoping to have a real shot at the NHL level.

With Tomáš Vokoun departing via free agency for the Washington Capitals, Markström attended Florida's September 2011 training camp to compete for a starting or backup position with fellow goaltenders José Théodore and Scott Clemmensen, ultimately being awarded the backup role when Clemmensen was injured.^[6] On 22 October, Markström earned his first NHL win when he played in the third period against the New York Islanders and made 18 saves on 18 shots.^[7]

Markström started the lockout shortened 2012–13 season in the AHL, but with the starter José Théodore suffering an injury on 2 March^[8] that forced him to miss the rest of the season, Markström was given the de facto full-time role, starting most of their games during the remainder of the season.

Vancouver Canucks

Markström with the Utica Comets in 2015.

It was believed that Markström would become the full-time starter for the Panthers at the beginning of the 2013–14 season, as Théodore was not retained and Markström signed a two-year contract extension. However, the Panthers would sign Tim Thomas to a one-year contract, and Markström was subsequently demoted to the AHL again. On 4 March 2014, he was traded by the Panthers, along with forward Shawn Matthias, to the Vancouver Canucks in exchange for Roberto Luongo and Steven Anthony, where he served as Vancouver's backup behind fellow Swede Eddie Läck.^[9]

Markström failed to make the Canucks out of training camp during the 2014–15 season. After clearing waivers, he was assigned to the Canucks' AHL affiliate, the Utica Comets. Following an injury to Ryan Miller, Markström was recalled to the Canucks to serve as backup to Eddie Läck and got to play on 3 March 2015, against the San Jose Sharks, but was pulled after he allowed three goals on four shots. The Canucks went on to lose the game 6–2. Markström came into a game on 19 March 2015 against the Columbus Blue Jackets and made two saves on two shots. However, the Canucks went on to lose that game 6–2 as well. Markström got his first and only win of the 2014–15 season when he made 26 saves on 27 shots on 22 March 2015, when the Canucks beat the Arizona Coyotes 3–1.

On 29 June 2015, Markström was re-signed to a two-year one-way contract with the Vancouver Canucks.^[10]

On 7 July 2016, Markström signed a three-year contract extension with the Canucks.^[11]

On 5 December 2017, Markström recorded his first NHL shutout, in a 3–0 Canucks victory over the Carolina Hurricanes.^[12]

On 12 December 2019, Markström recorded his fourth NHL shutout, stopping 43 shots on goal in a 1–0 Canucks victory over the Carolina Hurricanes, giving him a second-place franchise record for most shots stopped in a regular season game (tied with former Canucks goaltender Cory Schneider). On 3 January 2020, Markström was named to his first NHL All-Star Game, replacing the Vegas Golden Knights' goaltender Marc-André Fleury.

Calgary Flames

On 9 October 2020, Markström left the Vancouver Canucks as a free agent and signed a six-year, $36 million contract with the Calgary Flames.^[13] He finished with a record of 22–19–2 in 43 games in the pandemic-shortened 2020–21 season, having struggled with a concussion midway through following a collision with Canucks forward Tanner Pearson that was initially undiagnosed. The Flames narrowly failed to qualify for the 2021 Stanley Cup playoffs, finishing narrowly behind the Montreal Canadiens for the final berth in the all-Canadian North Division.^[14]

For the 2021–22 season, the NHL returned to its standard alignment, with the Flames again competing in the Pacific Division. Following a disappointing prior season that had seen a midseason coaching replacement, new coach Darryl Sutter spurred the team to one of its best in years. Markström had the best season of his career to date, managing a 37–15–9 record with a .922 save percentage and a league-leading nine shutouts.^[15] He was named a finalist for the Vezina Trophy, awarded to the league's best goaltender.^[16] The Flames won the Pacific Division, and advanced into the 2022 Stanley Cup playoffs to meet the Dallas Stars in the first round.^[15] The series against the Stars became a goaltending duel between Markström and Stars netminder Jake Oettinger, with the latter recording the highest save percentage of the first round, while Markström had the second-highest, and was "instrumental" to the Flames' eventual victory in seven games.^[17] The team faced the Edmonton Oilers in the second round, the first playoff series "Battle of Alberta" in 31 years.^[18] The match bore special significance for Markström, who had declined to sign with the Oilers in 2020, but he performed poorly in the series, recording a .852 save percentage in a five-game series loss.^[19]
