İlk gün 68 tur atan Power, 41. turunda hava koridorunun yardımıyla 229.745 mph hıza ulaşarak en yakın rakibi, IndyCar Grand Prix galibi takım arkadaşı Pagenaud'un 0.043 mph önünde yer almayı başardı.

Team Penske'nin diğer pilotu Helio Castroneves 4. olurken onların arasına 3. olarak Ed Carpenter girmeyi başardı.

2017'nin ardından tekrar Indy 500'e dönen Fernando Alonso, McLaren Racing-Chevrolet aracıyla 50 tur attı ve 32. oldu.
