Antipov defeated his first master-titled player in the 2nd Vyzhmanavin & Kiselev Memorial in April 2007 when he scored the full point against FM Viktor Kotov. Later that year, he placed 2nd in the European U10 championships, behind Kirill Alekseenko, and won his Candidate Master title when he came 2nd at the 2007 World U10 championships behind Tong Sen Wang, in the process taking revenge by defeating FM Alekseenko. In 2008, he contested the Moscow Open A, scoring 4/9 but capturing his first IM scalp, namely Alexey Alexeev. Also in 2008, he came =11th in the World U12 championship, with 7/11. In 2009, he had his first tilt at Aeroflot competing in the B division scoring 4/9. Later in 2009 he scored 8/11 in the World U12 championship placing =5th alongside tournament favorite Suri Vaibhav. In October and November 2010, Antipov scored his first two IM norms at the First Saturday Tournaments held in those months. In 2011, he scored 5.5/9 in the Marienbad Open 2011 - IM - B1, coming =3rd, and competed in the Aeroflot open 2011 B, where he scored 4.5/9, defeating GMs Kirill Stupak and Roman Ovetchkin and winning his 3rd IM norm. His 6/9 score at the 30th Zalakaros Open in Hungary in May 2011 - where he was half point behind joint second place and a point behind the winner - added over 35 rating points to take him over the 2400 barrier, meeting the final criterion for winning the IM title.

In August 2011, he came 4th in the Olomouc Summer GM tournament in the Czech Republic. In September, he scored 6.5/9 at the European U14 championship, a point off the lead, and in October 2011, he scored 5.5/9 at the 2011 Chigorin Memorial Open against opponents that included 6 GMs (+2 -3 =1) and an IM (+1). He scored his first GM norm by winning the First Saturday GM Tournament held in Budapest in December 2011 with a score of 7/9 (+5 =4), including victories against all three GMs he faced. He scored on par with 4.5/9 at the Aeroflot Open B to basically maintain his rating if not his world ranking and then scored an excellent 6.5/9 at Bosnia in May 2012, winning his 2nd GM norm, scoring 5/7 against his GM opponents and gaining 33 rating points. He followed with a par for rating 5/9 at the Alekhine Memorial 2012.

Antipov had a lean time of it in the Czech Open - A - GM, held in July 2012, scoring only 4.5/9, but made up much of the ground he lost in the event with a solid, if not winning, result at the World Junior Championship (2012), scoring 8.5/13, 1.5 points off the lead. However, a poor showing (4/9) at Livigno in Italy in September 2012 undid these gains. Winning the First Saturday GM Tournament in December 2012 had again restored some of his fortunes but with 6.5/9, he was a half point short of winning his 3rd GM norm.

As of 1 May 2013, Antipov's rating was 2464. He is Russia's 3rd ranked player U16 and the 8th in the world in that age division. His rapid rating is 2563 and his blitz rating 2506.
