2010–2014: Top 300 in singles

Ćaćić competed both in singles and doubles events, mainly on ITF Men's Circuit and ATP Challenger Tour level.

Having played with his compatriots, including Marko Djokovic, Ilija Bozoljac and Dušan Lajović, he has taken part in three ATP World Tour main doubles tournaments held in Belgrade (in 2010 and 2012) and Umag (in 2012), where he lost in the opening rounds.

In the summer of 2014, after a series of successful appearances in Challenger tournaments played on a clay surface, Ćaćić moved into the top 300 and achieved his career-high ATP singles ranking of No. 281.

2015

Ćaćić did not participate in any tournament during the 2015 season due to injury, which caused a drop from both world singles and doubles rankings.

In January, he was part of Serbian team that won inaugural 2020 ATP Cup by defeating Spain in the final.

In February, he won his second ATP Tour title in Lyon, partnering Mate Pavić.

2021: Third doubles title, French Open quarterfinal, Three more finals, top 35

He partnered with Tomislav Brkić and won the doubles title at the ATP Buenos Aires, which was only their second tournament as a team. They also reached the finals of Andalucía Open and semifinals at Serbia Open. Following these results, he entered the top 50 in doubles at a career-high ATP doubles ranking of No. 48 on 26 April 2021.

The pair also reached the quarterfinals of the 2021 French Open for their best showing in their careers, defeating Marcel Granollers/Horacio Zeballos and Máximo González/Simone Bolelli en route.

On 8 November 2021, Cacic reached a career high of World No. 35 in doubles.

In October, again partnering Victor Vlad Cornea in Basel as a lucky loser pair, they reached the quarterfinals by defeating Swiss duo Mika Brunold and Marc-Andrea Hüsler in straight sets.

2024: United Cup debut, Win over world No.1

Partnering with compatriot Dejana Radanović, he made his debut at the 2024 United Cup as part of team Serbia.

At the 2024 Australian Open partnering Denys Molchanov the pair defeated the world No. 1 and No. 2 players, the top seeded pair of Austin Krajicek and Ivan Dodig in the second round to reach the third round for the second time at this Major.^[6]
