A decade ago, a fund built entirely around walking, talking robots would have sounded like science fiction with a ticker symbol. In 2026 it is a real, tradable fund with tens of millions of dollars inside it. The Roundhill Humanoid Robotics ETF (HUMN) is one of the first products built to let ordinary investors bet on humanoid robots becoming a mainstream industry. This is the complete story: what it holds, how it works, where it came from, and the risks hiding behind the hype.
What is the HUMN ETF?
HUMN is an actively managed exchange-traded fund from Roundhill Investments that holds a basket of companies building humanoid robots and the parts that make them move and think. Launched in June 2025, it gives everyday investors a single ticker tied to the humanoid robotics theme, spanning the Chinese and Korean firms shipping actual robots and the US chip and component suppliers powering them. Instead of guessing which single robot maker wins, you own a slice of roughly three dozen of them at once.
The Humanoid Robot Boom: Why This ETF Exists
HUMN exists because a niche science project turned into one of the hottest investment themes on the planet. After Tesla showed off its Optimus robot and a wave of Chinese makers began shipping units at scale, 2025 and 2026 became the years humanoids went from demo videos to real deployments.
The numbers behind the theme are enormous, and wildly uncertain. The global humanoid robot market was worth only around $5 billion in 2026, but forecasts for 2035 range from roughly $30 billion on the conservative end to well over $250 billion in the most aggressive scenarios, with growth rates estimated anywhere from the high 20s to nearly 50 percent per year. Nobody really knows how big this gets, which is exactly why a fund like HUMN is both exciting and dangerous.
One fact stands out: China is winning the early race on volume. Morgan Stanley has estimated that China accounted for more than 80 percent of the roughly 16,000 humanoids deployed worldwide in 2025, led by Unitree, the world's top seller, and AgiBot. Western names like Figure AI, Agility Robotics, Boston Dynamics, and Tesla are racing to catch up on units shipped. This global split shapes everything about how HUMN is built.
Inside HUMN: What It Actually Holds
HUMN spreads its bets across what the industry calls the robot's "brain" and "body." The brain is the chips and AI that let a robot see, balance, and decide, and here the key enabler is Nvidia (NVDA), whose platforms power much of the physical-AI push. The body is the physical hardware: the precision gears, actuators, motors, and sensors that let a machine actually walk and grip.
Its holdings reflect the global nature of the race. Top positions have included the Chinese maker Unitree (listed as Yushu Technology) at around 6 percent, Tesla (TSLA) near 5.5 percent for its Optimus program, and Japan's Harmonic Drive Systems, a maker of the precision gears that act as a humanoid's joints, at roughly 4.7 percent. Chinese names like UBTech sit alongside Korean and US suppliers. Because the fund is actively managed, it also parks a chunk in short-term Treasury bills as cash, which is normal for a young, volatile strategy.
HUMN by the Numbers
The hard data tells you this is a small, fast-moving fund. HUMN recently traded around $29 per share, within a 52-week range of about $26 to $39, which already hints at how much it swings. Its expense ratio is 0.75 percent, on the higher side because it is actively managed, and its assets under management sit around $90 million, which is tiny by ETF standards.
Performance has been a roller coaster. The fund was up roughly 12 percent year to date and around 27 percent over the trailing year at points in 2026, but it got there through violent monthly moves, including a near 20 percent gain in one month and a 16 percent drop in another. This is not a sleepy index fund. It is a high-beta bet on an emerging theme.

Roundhill Investments made its name launching sharp, thematic ETFs aimed at whatever the market is most excited about, and humanoid robotics was a natural target. It launched HUMN on June 26, 2025, right as humanoid hype was peaking.
One honest footnote on the "first" claim: KraneShares brought its own humanoid fund, KOID, to the Nasdaq on June 4, 2025, a few weeks earlier. So while HUMN is often described as a pioneer, it was not strictly the first US-listed humanoid ETF. What it offered instead was a purely active, concentrated take on the theme. Since launch, HUMN has ridden the broader AI and robotics wave, with its price swinging hard on robot demos, earnings from chip suppliers, and shifts in the China-versus-US narrative.
HUMN vs KOID: The Two Humanoid ETFs
If you are shopping the theme, these two funds are the main choice, and they are built very differently.
KOID, from KraneShares, is passive. It tracks an index (the MerQube Global Humanoid Robotics and Physical AI Index), charges a slightly lower 0.69 percent, and is far larger, with assets around $343 million, roughly three to four times HUMN's size. It splits the theme across the brain, the body, and the integrators that assemble finished robots.
HUMN, from Roundhill, is active. A manager picks and weights the holdings rather than following an index, which can help it move faster into winners but costs a bit more and depends on the manager getting it right. Through 2026, both funds posted broadly similar returns. The practical takeaway: KOID is the cheaper, bigger, more diversified index option, while HUMN is the smaller, nimbler, actively managed bet.
The Risks You Should Know
A theme this hyped carries real hazards, and you should weigh them before buying.
- It is tiny and young. At around $90 million and barely over a year old, HUMN is a small fund. Small ETFs can and do close if they fail to gather assets.
- It is volatile. Double-digit monthly swings are normal here. This is a satellite position, not a place to park money you need soon.
- It is heavy on China. Several top holdings are Chinese makers, which brings geopolitical, regulatory, trade-war, and potential delisting risk that US investors cannot control.
- The industry is mostly pre-profit. Many humanoid companies are not yet profitable. You are paying today for a future that may take a decade and may not arrive on schedule.
- Thematic funds can be early or wrong. Narrow themes often get crowded, run ahead of reality, or stall for years before paying off.
Frequently Asked Questions
What does the HUMN ETF invest in?
HUMN holds roughly three dozen companies tied to humanoid robotics, including robot makers like Tesla and Unitree, component suppliers like Harmonic Drive, and chip enablers like Nvidia, plus some cash in Treasury bills.
Is HUMN a good investment?
It is a high-risk, high-potential thematic bet. The humanoid market could be huge, but the fund is small, volatile, and China-heavy. It suits a small speculative position, not a core holding.
What is the difference between HUMN and KOID?
HUMN is actively managed (0.75 percent fee, around $90M). KOID is a larger, passive index fund (0.69 percent fee, around $343M). Both target humanoid robotics, but KOID is cheaper and more diversified while HUMN is nimbler.
The Bottom Line
HUMN is the cleanest way to bet on humanoid robots in a single trade, and the theme behind it is real and potentially enormous. But the fund is small, volatile, concentrated in Chinese makers, and built on an industry that is still mostly burning cash on a future that has not arrived. In my view, HUMN only makes sense as a small, speculative satellite position for investors who truly believe humanoids are the next great hardware wave and can stomach big swings. If that is you, size it like the gamble it is, and compare it honestly against the cheaper, larger KOID before you choose. The robots may be coming. Your portfolio should still be built for the chance that they take longer than Wall Street hopes.
