The title of "Fastest Guy on Earth" is never a settled matter. As of today, December 12, 2025, the debate is split between two phenomenal athletes: the legendary, untouchable world record holder, and the explosive new sprinter who has clocked the fastest time of the current season. While Usain Bolt’s historic 9.58-second 100-meter dash remains the ultimate benchmark, a new Jamaican sensation, Kishane Thompson, has seized the 2025 world lead, igniting a fresh and intense rivalry in the world of sprinting.
This article dives deep into the two definitions of speed, examining the enduring legacy of the all-time great and providing an up-to-the-minute look at the current track and field landscape. The 2025 season has delivered some of the fastest times in history, setting the stage for a spectacular showdown that could finally threaten the seemingly unbreakable world record.
Kishane Thompson: The New King of Speed in 2025
The current fastest man on the planet, based purely on the best time recorded in the 2025 season, is Jamaica's Kishane Thompson. The young sprinter has emerged from the shadow of his legendary countrymen to lay down a marker that has reset the conversation around the 100m dash. His phenomenal performance has immediately placed him among the elite sprinters in history.
Kishane Thompson: Biographical Profile
- Full Name: Kishane Thompson
- Nationality: Jamaican
- Born: 17 July 2001 (Age 24 as of Dec 2025)
- Birthplace: Mitchell Town, Jamaica
- Height: 1.85 m (6 ft 1 in)
- Weight: 85 kg (187 lb)
- Coach: Stephen 'Franno' Francis (MVP Track Club)
- Event: 100 Metres, 60 Metres, 200 Metres
- 2025 World Lead Time (100m): 9.75 seconds
- All-Time Rank: Tied for the sixth-fastest man in history (at the time of the run)
Thompson's breakthrough moment came at the 2025 Jamaican National Championships in Kingston. He blazed across the finish line with a time of 9.75 seconds with a legal tailwind of 0.8 m/s. This performance immediately established him as the world leader for the year and cemented his status as a major contender on the global stage. His coach, Stephen Francis, a man who has molded numerous Jamaican champions, has expressed confidence in Thompson's potential, noting his unique ability to excel at both quick starting and powerful acceleration.
The Unbreakable Benchmark: Usain Bolt’s Enduring Legacy
While Kishane Thompson holds the 2025 world lead, the undisputed "Fastest Man on Earth" in terms of the all-time record remains Usain Bolt. His world record, set at the 2009 World Championships in Berlin, is a time that has stood for over 16 years and continues to defy the current generation of sprinters.
The World Record That Defines Speed
- Usain Bolt's 100m World Record: 9.58 seconds (Set in 2009)
- Usain Bolt's 200m World Record: 19.19 seconds (Set in 2009)
The gap between Bolt's record and the current world-leading time of 9.75s by Thompson is a significant 0.17 seconds—a chasm in the world of elite sprinting. Even in 2025, Bolt remains supremely confident that his records are safe. He has publicly stated that his 100m time is an "incredible time" that he believes will stand for years to come, dismissing any immediate threat from the current cast of sprinters. This confidence highlights the sheer historical anomaly of Bolt's peak performance, a moment of athletic perfection that has yet to be replicated.
The 2025 Sprint Rivalries: The Battle for Supremacy
The 2025 season is shaping up to be one of the most competitive in recent memory, with a trio of sprinters consistently clocking times under the 9.80-second barrier. This intense competition is what truly makes the title of "fastest guy" so compelling, as it is constantly being challenged in real-time. The rivalries between the top athletes are the engine driving the sport forward and fueling the hope of a new world record.
The Top Contenders and Their 2025 PBs:
Behind Kishane Thompson's 9.75s, the American sprinters are leading the charge, creating a classic Jamaica vs. USA dynamic that dominates the sport. The emergence of these fast times suggests that the depth of talent is higher than it has been in years.
1. Kenny Bednarek: The American Challenger
Kenny Bednarek has had a phenomenal 2025 season, culminating in a personal best (PB) of 9.79 seconds to win the USATF Outdoor Championships. This time makes him the second-fastest man in the world this year. Bednarek, known primarily as a 200m specialist, has translated his explosive power to the shorter distance, making him a major threat in any 100m final. His victory over a stacked American field has positioned him as the primary challenger to Thompson's world lead.
2. Noah Lyles: The Olympic & World Champion
World and Olympic champion Noah Lyles is the biggest name in the sport, but his 2025 100m season has been a battle against the new speedsters. Lyles is locked in a burgeoning rivalry with Thompson. The two have already met in several high-profile races, notably at the Silesia Diamond League, where Thompson pipped Lyles in a thrilling finish. Lyles remains the man to beat in the 200m, but his focus on the 100m makes every head-to-head with Thompson a must-watch event, often billed as a "world's fastest man" rematch.
3. Bryan Levell: The Rising Jamaican Star
Another young Jamaican sprinter, Bryan Levell, has also thrown his hat into the ring. Levell recorded a blistering 9.82 seconds at the Raiffeisen Austrian Open, making him the third-fastest man of the 2025 season, trailing only his countryman Thompson and Kenny Bednarek. This performance underscores the incredible depth of Jamaican sprinting talent and ensures that the competition for national team spots is as fierce as the international races.
What Will It Take to Break 9.58 Seconds?
The pursuit of the 9.58-second barrier is the ultimate quest in athletics. Experts agree that a combination of factors must align perfectly for the record to fall. It is not simply about raw speed; it involves biomechanics, meteorology, and mental fortitude.
- Perfect Conditions: The race requires an optimal tailwind (the maximum legal limit is +2.0 m/s), high altitude (though Bolt's record was at low altitude), and a fast track surface.
- The Start: Bolt's weakest phase was his start. A sprinter with Bolt's top-end speed but a superior reaction time and acceleration, like a Thompson or Lyles, could theoretically shave off the necessary hundredths of a second.
- Peak Acceleration: The ability to maintain maximum velocity through the 60m-80m mark is crucial. Thompson's 9.75s run suggests he has this elite-level acceleration.
The current generation, led by Kishane Thompson, Kenny Bednarek, and Noah Lyles, is running faster than any group since the peak Bolt era. Their consistent sub-9.80 performances are a strong indication that the record is under pressure. While Usain Bolt may be "not worried" right now, the sheer volume of elite speed in 2025 suggests that the gap is closing, and the next definitive "Fastest Guy on Earth" may yet be the one who finally dethrones the legend.
