BOTT vs CABZ

BOTTBThemes Humanoid Robotics ETF

CABZDRoundhill Robotaxi, Autonomous Vehicles & Technology ETF

In short

BOTT Most robotics funds buy the whole factory floor. BOTT buys the androids: about 30 global names across the humanoid and service robot value chain, at 0.35% a year.

CABZ Most robotics ETFs buy factory arms and humanoids. CABZ narrows the lens to driverless: an actively managed basket of about 30 robotaxi, autonomous-vehicle and enabling-tech names, launched in 2026.

Stated mandate

BOTT The Fund seeks to track, before fees and expenses, an index of companies deriving significant revenue from designing and developing humanoid and service robots.

CABZ CABZ is an actively managed ETF investing in equity securities of companies involved in robotaxis, autonomous vehicles, and related technology.

Why people hold it

• BOTT At 0.35% it undercuts the typical robotics and automation ETF (median 0.65%) and every peer ranked above it: IBOT at 0.47%, FBOT and FDIF at 0.50%.
• A true pure play. Its index, the Solactive Global Humanoid Robotics Index, targets companies building humanoid and service robots, not the broad factory automation basket.themesetfs.com
• Global mandate, about 30 names. Tight enough that the humanoid theme actually shows up in the portfolio instead of getting buried under mega-cap ballast.themesetfs.com
• Sits in the upper half of its robotics and automation peer group, one of the stronger builds of a very young theme.

• CABZ The mandate is robotaxis, autonomous vehicles and the technology underneath, not robotics broadly, so the driverless theme stays undiluted by factory automation.roundhillinvestments.com
• Actively managed, so the manager can move between chipmakers, sensor suppliers and fleet operators as the autonomy race shifts, rather than waiting on an index committee.roundhillinvestments.com
• At 0.59% a year it prices below the median robotics-and-automation ETF, which is uncommon for an active fund working a theme this narrow.

Worth knowing

• BOTT Lightly traded next to the category's giants, so spreads can be wider and bigger orders need more care at the point of trade.
• Short file: the fund launched in 2024 and Themes relaunched it with the humanoid focus in 2025, so there is little live history to judge.globenewswire.com
• About 30 stocks in one early-stage theme is concentrated, swingy exposure, and cash comes back to you once or twice a year at most.

• CABZ Roughly 30 holdings in one narrow theme: news at a single company can move this fund more than a diversified tech basket.
• It launched in January 2026, so there is no long record to judge, and newer, smaller funds tend to trade with wider bid/ask spreads.
• Broader robotics exposure costs less elsewhere (BOTT at 0.35%, IBOT at 0.47%), though neither is built specifically around autonomous driving.
