Noah Lyles won the gold medal, setting a new personal best in the 100m and giving the United States its first victory in the event since 2004.

Interestingly the final contained 6 men who had recorded top-25 all-time records in the 100m, making this final one of the most tightly contested in history, as the difference between the fastest man in the field Fred Kerley (9.76) and the slowest Kenny Bednarek (9.87) was only 0.11 seconds.

Noah Lyles came through in 1st place, 0.005 seconds ahead of 2nd-placed Kishane Thompson, marking possibly one of the closest 1–2 finishes in Olympic 100-metre history.

Fred Kerley, who won silver at the 2020 Summer Olympics was in lane 3 as the 4th fastest qualifier with a time of 9.84.

Noticeably absent in the final was Ferdinand Omanyala who had set the 2nd fastest time of 2024 just 6 weeks prior in June Lyles' win was the first American gold medal in the 100m race since Justin Gatlin won in 2004.

[4][5] The top 6 all ran times that would have guaranteed a gold, silver or bronze in every single Olympic 100m race prior (except for 2012).

The 100 metres is considered one of the blue ribbon events of the Olympics and is among the highest profile competitions at the games.

Season leaders were Kishane Thompson with 9.77, Ferdinand Omanyala 9.79, reigning World Champion Noah Lyles 9.80 and Oblique Seville 9.82.

The podium from three years earlier all returned, defending champion Marcell Jacobs, Fred Kerley and Andre De Grasse.
