Kostić signed his first professional contract with FK Radnički 1923 in 2010 at the age of 17. This was after the club was promoted to the Serbian SuperLiga from the Serbian First League. He began attracting the interest of several clubs including Red Star Belgrade, Anderlecht, Udinese, and Tottenham Hotspur. On April 15, 2012, he was named starting left winger in Sportal's ideal team of round 24 in the SuperLiga.
On April 4, 2012, he signed a contract with Eredivisie side FC Groningen and moved to the Netherlands in June 2012 after the end of the season. He made his debut for Groningen on October 21, 2012. After getting little playing time, Kostić finally began showing promising potential from the beginning of the 2013-14 Eredivisie; he attracted media attention after playing a brilliant game in which he had one assist against NEC, and then on August 25 he added to his reputation of play-making by assisting twice against Go Ahead Eagles. Finally, on October 20, 2013, Kostić scored his first ever goal for Groningen in a 1–0 win against PSV Eindhoven. Kostić received criticism for a media interview after drawing 0–0 with Aberdeen F.C. in the second round of the Europa League qualifiers. He went on record after the match saying, “We go home happy, we have done 80% of what we need to go through”. Groningen went on to lose the tie with the Scottish club 1–2 at the Euroborg. Aberdeen F.C. winger Johnny Hayes was later quoted as saying "I was quite happy ramming their words down their throats".
On 9 August 2014 Filip Kostić moved to German side VfB Stuttgart for a fee of €6 million and a possible bonus of €1 million. FC Groningen also would get 15% of a future transfer fee received by Stuttgart. Kostić signed a contract until June 2019 with VfB Stuttgart.
After the relegation of VfB Stuttgart at the end of the season 2015/16, Kostić was transferred to Hamburger SV for a fee of €14 million, making him the most expensive buy in the history of the club.
On 7 June 2015 Kostić made his debut for the Serbia national senior team against Azerbaijan in a 4–1 friendly win in Sankt Pölten, Austria, making way for Lazar Marković after 56 minutes. He played in his first competitive match for Serbia on 13 June 2015 in the UEFA Euro 2016 qualifying Group I against Denmark.On the 5th September 2016 he scored his 1st International goal against the Republic of Ireland in a 2–2 draw.
