The 17-year old Indian is in joint lead with 12 match points along with world No.1 Magnus Carlsen, who defeated Quang Liem Le of China 3-1.
Praggnanandhaa won the third game with white pieces after the first two in the four-game match ended in a stalemate.
First, he won with white pieces to take a 2-1 lead after game three and stormed to victory in 44 moves in the fourth to seal an emphatic win over the acclaimed American star.
Having started his campaign with victory over Alireza Firouzja, the Indian GM has subsequently beaten Anish Giri and Hans Nieman.
