CABZ vs FBOT

CABZDRoundhill Robotaxi, Autonomous Vehicles & Technology ETF

FBOTBFidelity Disruptive Automation ETF

In short

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.

FBOT Most robotics funds hand the job to an index. FBOT hands it to Fidelity's analysts: about 50 global picks spanning industrial robots, machine vision, autonomous driving and 3D printing, for 0.50% a year.

Stated mandate

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

FBOT The fund seeks long-term capital growth by normally investing at least 80% of its assets in securities of disruptive automation companies.

Why people hold it

• 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.

• FBOT Fidelity's analysts pick the names, and the fund's definition of automation runs from robotics and machine vision to autonomous driving, EVs and 3D printing.sec.gov
• At 0.50% a year it undercuts the typical robotics and automation fund, and it concentrates in about 50 stocks rather than spreading the theme thin.
• Born a 2020 Fidelity mutual fund, converted to an ETF in 2023, so there is real live history behind the strategy and holdings posted daily.fidelity.com
• One of the stronger builds in the robotics and automation group on cost, portfolio construction and risk profile.

Worth knowing

• 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.

• FBOT Thinly traded next to the giant thematic funds, so bid-ask spreads and order size matter more here.
• Two peers charge less: BOTT at 0.35% and IBOT at 0.47%.
• No index to fall back on. Results ride on the manager's calls, and the theme can reach into any sector, so the fund can behave unlike broad tech.sec.gov
