Marko Anttila played his first senior-level ice hockey games during the 2003–04 season. Anttila's first team was his hometown team
Lempäälän Kisa of
Lempäälä. Anttila scored 38 points in 22
Suomi-sarja regular season games during his debut season. Though playing at the 3rd highest level in Finland, Anttila was drafted by the
Chicago Blackhawks in the
2004 NHL entry draft while he was playing for LeKi. It is believed that Anttila's connections with Chicago's scout for Finland,
Sakari Pietilä, was the reason why he was drafted. His large size (over 6'8 ft tall) combined with his hard slap shot was the most convincing factors that influenced Sakari Pietilä to suggest him to the Blackhawks. After being drafted while playing for a small town's team, Anttila soon was reckoned as a player to invest in. Marko Anttila was contracted by
Ilves in 2004. Anttila struggled during his first season in
SM-liiga but soon got the hang of playing at higher levels. In 2007–08, Anttila scored his SM-liiga career-high when he racked up 23 points in 56 games, and he was selected to play for the Finnish National team during the European Hockey Tour. On 26 April 2011, Anttila made a one-year contract with
TPS. In June 2013, it was announced that Anttila would join
Metallurg Novokuznetsk of the
KHL. After parts of three seasons with
Örebro HK of the
Swedish Hockey League, Anttila returned to the KHL, linking up on a one-year deal with Finnish-based club Jokerit on 20 April 2016. During the
2016–17 season, having added a physical presence to the checking lines, Anttila agreed to a two-year contract extension to remain with Jokerit on 8 January 2017. Anttila remained with Jokerit for six years before the club's withdrawal to the KHL before the playoffs in the
2021–22 season due to the
Russian invasion of Ukraine. He subsequently joined his original Finnish club, Ilves of the Liiga, on 28 February 2022, for the remainder of the campaign. On 16 June 2022, it was announced that Anttila has signed for
Oulun Kärpät for the
2022–23 season. During the season he signed one-year extension. His contract was extended one-year further for the
2024–25 season. He was appointed as the captain of Kärpät for the season, which turned out to be his last, as he retired after the disappointing season. ==International play==
