Polesitter Christopher Bell led Ross Chastain and the rest of the field to the green flag.
Derek Kraus, driving in the 16 for Kaulig Racing, led at lap 40 during a round of green flag pit stops. Meanwhile, Kyle Larson narrowly passed Chastain for position.
Denny Hamlin won Stage One keeping Chastain at bay.
Larson made a three wide pass on lap 89 to take the lead as Chris Buescher made it five-wide to take the second position.
Chris Buescher won Stage Two over Larson.
Buescher unfortunately had to restart at the tail end of the longest line as his pit crew was over the wall too soon during stage break pit stops.
The first caution (other than stage breaks) came out for a multi-car incident involving Corey LaJoie, Austin Hill and Jimmie Johnson.
The second caution came out for a wreck involving Austin Cindric, Bubba Wallace and Michael McDowell.
Buescher and Hamlin swapped the lead for several laps but the caution came out for Kyle Busch spinning with 7 laps to go.
Buescher led the restart and took the white flag, but coming off of turn four Larson and Buescher bang off each other. It was a historic photo finish Larson wins the Advent Health 400!
Officially Larson won by 0.001 seconds, the closest finish in NASCAR history.
