The robotics investment landscape just split into two distinct paths, and your choice between them depends entirely on how bullish you are about humanoid robots specifically. BOTZ, the Global X Robotics and Artificial Intelligence ETF, has tracked the broad automation economy since 2016 with roughly 40-plus holdings spanning industrial automation, AI infrastructure, and surgical robotics. KOID, the KraneShares humanoid robotics ETF, launched in 2025 as a pure-play bet on companies building humanoid platforms, components, and embodied AI systems. The two funds answer fundamentally different investment questions, and understanding that difference is critical before choosing between them.

What Makes These Two ETFs So Different?

BOTZ and KOID operate on opposite ends of the robotics spectrum. BOTZ spreads your investment across the entire automation economy, treating humanoid robots as one thread in a much larger tapestry. The fund holds the infrastructure layer of global automation: NVIDIA supplies the computing power, Intuitive Surgical dominates surgical robotics, and Japanese industrial giants like ABB, Fanuc, and Keyence run the factory automation backbone. Humanoid exposure exists in BOTZ only indirectly, through these diversified holdings, never as the organizing thesis.

KOID exists for one reason: direct exposure to the humanoid buildout. The fund concentrates on companies with revenue or roadmap exposure to humanoid platforms, components, and the embodied intelligence layer. This concentration is intentional. The investable humanoid universe today runs through actuator makers, sensor suppliers, compute providers, and public manufacturers like Agility Robotics, which reached public markets through a SPAC deal. KOID packages that universe into a single ticker, while BOTZ dilutes it across the whole automation economy.

How Do These Funds Handle Risk Differently?

The risk profiles of these two funds move in opposite directions, and that matters enormously for portfolio construction. BOTZ is a diversification instrument; a humanoid winter would dent the fund without breaking it, because surgical robotics, factory automation, and AI infrastructure carry the portfolio. The cost of that safety is dilution. A humanoid boom lifts BOTZ modestly, because humanoid exposure represents only a fraction of the fund's thesis.

KOID concentrates risk on one category. A humanoid boom is the entire payoff scenario. A humanoid winter hits the whole portfolio at once, because concentration cuts both ways. Pure-play funds swing harder than diversified funds in both directions by design. Position sizing, not fund selection, is how investors manage that volatility difference in practice.

How to Choose Between Broad Robotics and Humanoid Concentration

• Track Record and Stability: BOTZ launched in September 2016 and has traded through nearly a decade of full market cycles, with a proven 0.68 percent expense ratio that has held steady for years. KOID launched in 2025 and is still in its first full cycle, making it a newer, smaller fund with wider spreads and a shorter trading history.
• Size and Liquidity: BOTZ holds approximately 3.38 billion dollars in assets under management, while KOID holds approximately 327 million dollars. The size difference translates directly to trading liquidity; BOTZ offers tight spreads and high daily volume for investors trading in size or running regular contributions.
• Thesis Purity: BOTZ delivers broad automation exposure through the Indxx Global Robotics and Artificial Intelligence Thematic Index with roughly 40-plus holdings. KOID delivers concentrated humanoid exposure through approximately 58-plus holdings tracked by the MerQube Global Humanoid Robotics and Physical AI Index, making it a direct bet on the humanoid decade.

Performance between the two funds tracks the humanoid news cycle. Production milestones from Tesla, Figure, and other leading humanoid robot companies move KOID directly and BOTZ at the margin. The expense ratios tell part of the story: BOTZ charges 0.68 percent, while KOID charges 0.79 percent gross or 0.69 percent net. That difference is modest, but it reflects the cost of maintaining a specialized index versus a broad one.

Which Fund Fits Your Investment Profile?

BOTZ fits the investor who wants robotics exposure without category risk. The fund rewards patience with diversification, an established record, and the infrastructure names that win regardless of which robot form factor dominates. This is a core robotics allocation held through cycles, not a bet on any single technology path.

KOID fits the investor with a specific humanoid conviction. The fund rewards being right about the humanoid decade and punishes being early or wrong, because concentration amplifies both outcomes. This is a satellite position expressing a direct humanoid thesis, sized to your risk tolerance.

Holding both is a coherent structure. BOTZ as the core, KOID as the conviction satellite. The split expresses broad exposure with a measured humanoid tilt, sized to the investor's risk tolerance. Neither fund is better in absolute terms because each answers a different question. BOTZ is better for diversified robotics exposure with a long track record. KOID is better for direct, concentrated exposure to the humanoid robotics buildout.
