Tiangong Ultra Runs 100m in 9.39s — a Humanoid Just Beat Usain Bolt's Record

For seventeen years, Usain Bolt’s 9.58-second 100-meter world record from the 2009 Berlin World Championships has stood as one of the untouchable monuments of human athletics. On Saturday evening, August 22, 2026, it fell — not to a sprinter, but to a 1.8-meter-tall bipedal machine. At the opening of the second World Humanoid Robot Games in Beijing, a humanoid robot named Tiangong Ultra completed a 100-meter exhibition sprint in 9.39 seconds, beating Bolt’s mark by nearly two tenths of a second.

The moment was captured on video and verified by judges at the National Speed Skating Oval, the ribbon-roofed venue known as the “Ice Ribbon” that hosted the 2022 Winter Olympics speed skating. The robot crossed the line at roughly 23.8 mph — and then, having no elegant way to decelerate from that velocity, plowed into a padded wall of foam at the end of the runway, toppling over as the crowd roared.

Who is Tiangong Ultra?

Tiangong Ultra is built by X-Humanoid, the commercial venture spun out of the Beijing Humanoid Robot Innovation Center — the state-backed consortium that has produced some of China’s most visible humanoid platforms. The machine is a familiar figure on the Chinese robot-sports circuit: it won the world’s first humanoid half-marathon in Beijing in April 2025, covering 21.1 km in 2 hours 40 minutes 42 seconds. Its older marathon configuration topped out around 12 km/h at 55 kg; the sprint version that ran this weekend is a different beast entirely, reportedly reaching 12.66 meters per second in pre-Games testing — a pace that would exceed Bolt’s own recorded peak velocity.

Honor, the Chinese smartphone maker that has aggressively moved into embodied AI, took second place with its “Lightning” robot. Lightning is itself a proven sprinter: at the Beijing E-Town half-marathon event in April 2026 it ran a documented 9.32-second 100m in a trial — under Bolt’s record, though outside official Games judging. On Saturday, two machines dipped under the human world record in the same exhibition, a detail that would have sounded like science fiction when the first edition of these Games was held just a year ago.

A Games that quadrupled in one year

The World Humanoid Robot Games, first held in Beijing in August 2025, is the world’s only international multi-sport event where humanoid robots are the primary athletes. The second edition, running August 22–26, 2026, has exploded in scale: 2,056 robots from 666 teams across 16 countries and six continents, competing in 51 events and more than 1,300 scheduled matches. Last year’s inaugural edition drew roughly 500 robots and 280 teams — meaning participation grew about 311% year-over-year by robot count and 138% by team count.

The program has also widened far beyond track. Robots now compete in 5v5 football (with qualifiers held August 11–16), basketball free-throws, table tennis, archery, gymnastics-style routines, and taichi — the slow, balance-intensive martial art that turns out to be brutally difficult for machines that must constantly correct their own balance. Alongside the sporting events are “real-world challenge” contests modeled on industrial and household tasks, which is where much of the actual commercial interest concentrates.

Last year’s medal table was dominated by Unitree and X-Humanoid, with 11 and 10 medals respectively. Unitree’s G1 famously completed the 100-meter obstacle race in 33.71 seconds, and its H1 won the 1,500 meters in 394 seconds — numbers that look leisurely next to this weekend’s sprint times, and that illustrate just how fast the hardware-control frontier is moving.

The asterisk that matters

Let’s be precise about what happened, because the headlines compress it. The 9.39-second run was an exhibition sprint — a demonstration of top-speed capability, run on a straight course with safety padding at the end, not a gold-medal race in a full competitive program. Tiangong Ultra also won the official competitive 100m final at the Games; in the longer judged contests it clocked 21.50 seconds, a time that reflects the sustained-balance regime rather than the all-out sprint configuration. (For comparison, the human world record for a race-walk-adjacent pace, and indeed most amateur club sprinters, remain far behind these machines.)

The engineering trade-offs are visible in the crash itself. A biped running at 12.66 m/s carries enormous angular momentum through each stance phase; arresting that momentum requires either enormous braking force through the legs — which risks structural failure — or an external arrestor, hence the foam. Bolt decelerates gracefully over 30 meters after his finishes; Tiangong Ultra finishes by falling over, safely. It is a solved problem in the sense that no one was hurt and the record stands, but it marks the boundary between “faster than the fastest human” and “athletically complete.”

There is also the platform asymmetry. Tiangong Ultra sprints on legs optimized for exactly this task, with no obligation to also fold laundry or stock shelves an hour later. Human records are set by generalists; robot records are set by specialists. The honest framing is not “robots are better athletes than humans” but “specialized bipedal machines can now exceed human top speed on a straight line, under controlled conditions, for 100 meters.”

Why this matters beyond the spectacle

The record is a milestone, not a product. But the underlying stack — high-torque actuators, model-based balance control robust enough to survive 9-second ground contacts at speed, and the reinforcement-learned locomotion policies that keep a toppling-prone biped upright through a sprint — is precisely the technology that transfers to logistics, manufacturing, and disaster response. When Forbes called the Games’ event list “a market map,” the point was that each discipline (sprinting stresses actuator power density; taichi stresses balance control; football stresses multi-agent coordination and perception under contact) maps onto a distinct commercial capability.

The 2,056-robot field is also the clearest available proxy for the state of the global humanoid industry. A 311% year-over-year jump in participating machines, drawn from 16 countries, indicates that the population of demonstration-ready humanoids in the world roughly quadrupled in twelve months — and that China’s ecosystem, which supplied the bulk of the field plus both record-setters, currently operates at a cadence its competitors have not matched.

Both records — Honor Lightning’s April trial and Tiangong Ultra’s judged 9.39 — were set on Chinese soil, by Chinese-built machines, at Chinese-organized events. Whatever one’s view of the exhibition format, the pattern across the half-marathon, the Games, and now the 100m record is consistent: the frontier of dynamic bipedal locomotion is currently being pushed hardest in Beijing.

The Games run through August 26. The next records to watch are not the sprints — those may now be limited only by actuator physics — but the contact sports: football, in particular, where five robots per side must perceive, decide, and collide in real time. That is the discipline where the gap between machine highlight reels and machine reliability remains widest, and where next year’s quadrupling will be most meaningful.
