He finished on 8.5 points out of 10, half a point ahead of 19-year-old Indian grandmaster Karthikeyan Murali who scored a sensational win against the tournament top seed Maxime Vachier-Lagrave to finish second on 8 points.
Artemiev takes the £25,000 cheque for first prize, while Murali takes home the £20,000 second prize.
This is his first time in Gibraltar.
The last time there was a straight win at the Gibraltar Masters was in 2015.
