The 2025 season gave us a world champion nobody quite expected, a rivalry that refuses to settle and a teenager from Queensland who could break physics. As we enter the 2026 Diamond League, there is no clear favorite in the men’s 100m. Which, honestly, is exactly as it should be.
Sevilla sit on top, for now
Tec Sevilla entered 2025 as a name for serious fans, but the wider public mostly turned to the “promising Jamaican sprinter”. He left it as a world champion. At the World Athletics Championships in Tokyo in September, Sevilla beat both Kishan Thomson and Noah Lyles by 9.77 seconds to become the first Jamaican 100m world champion since Usain Bolt in 2015. That fact alone is worth sitting with for a moment.
The 2026 season of the Diamond League is where players and analysts are now paying close attention. Those who are familiar The best UK casino sites will know that the sprint markets opened unusually short at the top of the spread, reflecting a field where no name sets the odds the way Lyles once did.
Before Tokyo, Sevilla had already beaten Lyles twice in the Diamond League circuit, running 9.86 in London and 9.87 in Lausanne. Lyles finished second both times. It shouldn’t have happened. And yet it happened.
Lyles and Thompson aren’t going away
Noah Lyles won the 100m Olympic gold in Paris by 0.005 seconds over Thompson. Five thousandths. If you blinked, you missed the margin. A finish like this tends to follow the competition for years.
Lyles has been open about his 2026 mindset. He described the season as “all or nothing” ahead of Los Angeles 2028, calling Sevilla’s rivalry with Thompson “inspiring rather than difficult”. It reads like someone who has already handled the bronze in Tokyo and is quietly pissed off about it. Anger, if that’s what it is, seems to work. At the Diamond League in Rome in June, Lyles won the 100 m in a season-best 9.88, crossing the line with ten meters to spare and telling the press that he already knew he had won it before he reached the finish line. Meanwhile, Keeshan Thompson won silver in Tokyo, posting a world-leading 9.75 seconds in 2025, the fastest time in a decade at the time. He doesn’t lose often, and when he does, he comes back even sharper.
The three of them share a unique dynamic.
- Sevilla are the reigning world champions with championship flair
- Thompson holds the fastest time of the current cycle and tends to peak at the right time
- Lyles brings the most complete sprint package in the field, winning in Rome to open his 2026 Diamond League account and making it clear he’s not here to finish second.
The name is viewed by everyone
Then there’s gout. The 18-year-old Australian set an under-20 world record of 19.67 seconds in the 200m at the Australian National Championships in April 2026, a time that briefly broke social media and prompted genuine questions about the timing equipment. The sign is standing. He has also clocked 10.00 seconds in the 100m this year and is sixth in the Diamond League in Oslo, behind winner Letsile Tebogo in June.
Comparisons to a teenage Usain Bolt are inevitable and somewhat unfair to Gut, who is just doing what he does, which is run very fast and look unfazed by the attention. Can he translate junior dominance into diamond league senior wins against Sevilla, Thompson and Lyles is the question that will define much of the story of 2026.
Here’s where each contender stands heading into the season.
- Tech Sevilla (Jamaica) – reigning world champion, 9.77 PB, two Diamond League wins over Lyles in 2025
- Kishan Thomson (Jamaica) – 9.75 season world leader in 2025, Olympic silver medalist, consecutive biggest meets
- Noah Lyles (USA) – Olympic champion, three-time world medalist, self-described all-or-nothing 2026.
- Gout Gout (Australia) – under-20 world record holder, Diamond League newcomer, truly unknown ceiling
What really determines the 2026 season?
With no World Athletics Championships until Beijing 2027, the Diamond League crown is the biggest prize up for grabs this year. The final will take place in Brussels on 4-5 September 2026, just before the first World Athletics Championships in Budapest. That’s a lot of big athletics crammed into a two-week window, and the sprint fields will probably look a lot different by then than they do now.
The honest answer to “Who owns the 100m throne in 2026?” is that no one has yet. Sevilla have the strongest claim after Tokyo, but the Diamond League points race is different from the league final. It rewards consistency over the course of a season, not just the ability to produce one extraordinary race under pressure.
A few things that will shape the outcome.
- Can Lyles maintain the form he showed in Rome in a full Diamond League schedule?
- Can Gout perform against elite competition as he moves up to the Diamond League circuit?
- Does Thompson find the form that gave him 9.75 in 2025?
No one gets away with this. In 2026, the 100m is closer to a four-way contention than a coronation, and that’s probably the best thing that could have happened to the event.
