Prannoy came to prominence after winning the silver medal in Boys' singles at the 2010 Summer Youth Olympics.[4] He followed it up with another silver, this time at the Bahrain International Challenge, in 2011.[5] However, as he struggled for form and injuries, Prannoy endured a somewhat barren spell following these achievements.

His greatest victory came in the pre-quarters of the 2015 India Super Series, when he beat an in-form world number 2 Jan Ø. Jørgensen in 3 sets.[14] He played his heart out in the quarter-finals as well, but ultimately suffered defeat to Denmark's Viktor Axelsen.

However, he was defeated in the semifinal by third seed Chen Long.[19]
2021
Prannoy had a disastrous start to 2021 after exiting in the early rounds of the 2021 Swiss Open and the 2021 All England Open. However, he came back strongly in the second half of the year, most notably defeating reigning Olympic champion Viktor Axelsen in the 2nd round of the 2021 Indonesia Masters in November.[20] He got further success in the 2021 BWF World Championships, held in December, where he upset World no. 9 Ng Ka Long of Hong Kong in the 1st round and World no. 10 Rasmus Gemke in the pre-quarterfinals. He lost to the eventual world champion Loh Kean Yew of Singapore in the quarterfinals.[21] His consistent performances in the last few months of the year enabled him to rise to World no. 27 at the end of the year.
2022
Prannoy was part of the India squad for the 2022 Thomas Cup. In the quarter-final against Malaysia, he won the decider match against Leong Jun Hao to assure India a semi-final spot and its first-ever medal in the Thomas Cup.[22] He repeated this performance in the semi-final against Denmark, beating Rasmus Gemke in the deciding match to take India to the final,[23] which India eventually won.[24]
