Roundhill Robotaxi Autonomous Vehicles & Technology ETF (CABZ) is an exchange-traded fund that provides targeted exposure to companies involved in the development, production, and deployment of robotaxi and autonomous vehicle technologies. The ETF invests primarily in equity securities of domestic and foreign companies engaged in autonomous driving software and hardware, robotaxi fleets, lidar and sensor technologies, high-definition mapping, AI-driven ride-hailing platforms; electric and autonomous vehicle manufacturers; and related infrastructure providers such as data centers and edge computing solutions supporting AV operations. It tracks a modified market-cap weighted index selected based on thematic relevance to robotaxis and autonomy, with holdings diversified across technology, automotive, and transportation sectors targeting institutional and retail investors seeking growth in the autonomous mobility revolution. Headquartered in New York and managed by Roundhill Investments, launched in 2024, CABZ operates globally with primary exposure to U.S., Chinese, and European markets where AV innovation concentrates. In late 2025, the fund expanded its index methodology to increase allocations to emerging robotaxi operators amid Tesla's Robotaxi Day unveilings and Waymo's commercial scaling, while introducing enhanced ESG filters for sustainable AV supply chains; it also announced a strategic seed partnership with autonomy-focused venture funds to support index component liquidity.
