Three Humanoid Robotics ETFs Built for the Tesla Optimus and Figure AI Era Most Investors Have Never Heard Of

Humanoid robotics moved from concept videos to factory floors over the past 18 months, and three ETFs now offer materially different ways to play it: Themes Humanoid Robotics ETF (NASDAQ:BOTT), ROBO Global Robotics and Automation Index ETF (NYSEARCA:ROBO), and the Global X Robotics & Artificial Intelligence ETF (NASDAQ:BOTZ). Each captures the theme from a different angle, and only one is a true pure-play on the Tesla Optimus and Figure AI commercialization curve.

BOTT is the newest and narrowest, launched in 2024 as the only pure-play humanoid ETF. ROBO has been the legacy industrial robotics fund since 2013. BOTZ sits in between, anchored by automation giants but quietly accumulating positions in the Korean and Chinese humanoid names that most U.S. investors have never opened a brokerage tab for.

The humanoid commercialization curve

The investable thesis stopped being speculative when humanoid units started showing up on payrolls. Tesla is ramping Optimus production, Figure is rolling out Figure 02 in commercial deployments, and Apptronik units are working alongside humans in Mercedes plants. The picks-and-shovels layer, AI chips, vision sensors, actuators, and industrial automation backbones, is already generating revenue regardless of whether any single humanoid platform wins.

That split matters for ETF selection. A fund concentrated on the platform builders captures the upside if humanoids scale; a fund anchored in the enablers captures revenue today whether Optimus ships at 10,000 units or 1 million. The three funds below sit at different points on that spectrum.

BOTT: the only pure-play in the category

BOTT exists for one reason: there was no clean way to buy the humanoid theme as a single ticker until Themes ETFs launched it. The fund holds Tesla, Figure AI suppliers, and Boston Dynamics-adjacent names, which is the actual composition investors want when they search for "humanoid robotics ETF" and instead find that older robotics funds have a 10% weighting in chip equipment makers.

The performance tells the story of how concentrated this exposure really is. BOTT is up roughly 35% year-to-date and has more than doubled over the past year, with shares trading around $56. That is the kind of return profile that comes from owning a small basket of names tied directly to a single narrative, not a diversified portfolio.

The tradeoff is structural. BOTT is small, new, and concentrated. Liquidity is thinner than the legacy robotics funds, and the holdings overlap heavily with names that have already run hard on Optimus and Figure milestones. A delay in commercial humanoid deployment, or a single bad quarter from Tesla, would land harder here than in any other fund in the category. Investors choosing BOTT are buying the thesis in its purest form, which means accepting that the fund will trade like a leveraged bet on humanoid milestones.
