The future of transportation is leaving the laboratory and driving on roads near you (at least in some specific cities). What began as academic research decades ago, and moved into the commercial arena in 2009 with Google’s secretive launch of self-driving initiative Waymo, has evolved into robotaxis and autonomous vehicles that have the potential to reshape how we think about ground transportation.
Goldman Sachs research suggests that by 2030, the total addressable market (TAM) for North America and China could grow to $7.3 billion and $11.7 billion dollars, respectively, with even more room to grow as the industry matures and commercialization materializes. For North America alone, this would imply a 90% annual growth rate.
While early days, the benefits of self-driving cars and robotaxi deployment appear attractive, with the potential for labor cost savings and margin expansion while offering superior driver safety and a transformation to how consumers experience transportation.
Here are the six major autonomous vehicle manufacturers in the Roundhill Robotaxi, Autonomous Vehicles & Technology ETF (CABZ) that are making waves (or should we say tread marks?) on city roads now.*
Owned by Alphabet, Waymo is considered one of the leaders for self-driving cars and robotaxi services on the West Coast in the U.S. In 2025, Waymo completed more than 14 million trips (more than tripling public rides from last year) and appeared on pace to surpass 20 million lifetime trips by year-end. Waymo’s active fleet is made up of 2,500 fully driverless vehicles, operating commercially in San Francisco, Phoenix, Los Angeles, Austin, and Atlanta both via its own app and its partnership with Uber.

Apollo Go is Baidu’s autonomous ride-hailing service active in 22 cities globally, racking up 240 million autonomous kilometers (149 million miles), including 140 million fully driverless autonomous kilometers (87 million miles). The company has plans to expand into Europe, specifically through strategic partnerships with PostBus, the leading public transport operator in Switzerland. Baidu also has partnerships with Lyft and Uber to implement rollouts in specific markets in Germany, the U.K., Asia and the Middle East.

In addition to humanoid robotics and artificial intelligence, Tesla’s innovative pursuits make them a serious player in the robotaxi space. Tesla’s robotaxi fleet has surpassed 250,000 driverless miles in Austin, Texas, while eclipsing 1 million miles with a safety driver in the San Francisco Bay Area.

Pony AI’s Gen-7 robotaxi fleet is growing beyond its core market in China. Pony.ai operates fully driverless robotaxi services across Guangzhou, Shenzhen, Beijing, and Shanghai, and is expanding toward global markets, with a particular focus on Europe, supported by testing in Luxembourg and a partnership with ride-hailing company Bolt. The current fleet stands at roughly 720 robotaxis, with the intention to grow its driving fleet to over 3,000 vehicles in 2026.

Based in China, WeRide’s (WRD) robotaxi fleet operates in over 30 cities within 11 countries. WeRide has roughly 750 robotaxis deployed globally and are aggressively searching to expand their footprint. A clear signal of ambition was securing Abu Dhabi as the first city-level permit for fully driverless robotaxi operations outside of the U.S. The company also has partnered with Uber in the UAE and plans to expand to certain markets.

Amazon’s Zoox has one of the most unique autonomous vehicles due to its elimination of any type of steering wheel or pedals. Zoox is in the early stages of its deployment, with active operations in Las Vegas and San Francisco. The testing footprint is larger and growing, but the company remains in the early stages of testing and geofencing for various U.S. markets.

Robotaxi, Autonomous Vehicles and Technology Companies Risk. Robotaxi, Autonomous Vehicles and Technology Companies may be adversely affected by government spending policies and permitting regimes because they often rely, to a significant extent, on public‑sector demand, approvals and infrastructure. Other risks for these industries include evolving regulation and safety standards, product liability and regulatory investigations following incidents, supply chain constraints and export controls on critical semiconductors, cybersecurity and data privacy incidents, outages or service changes by cloud or communications providers, competition, rapid technological change, intellectual property disputes, geopolitical instability, financing constraints and shortages of skilled labor, among other things. Robotaxi, Autonomous Vehicles and Technology Companies may face challenges related to the obsolescence of existing systems and equipment as well as unexpected risks and costs from technological developments, such as autonomous driving, ADAS and AI.
Emerging Markets Risk. The Fund’s investments in China may be subject to a greater risk of loss than investments in more developed markets. Emerging markets may be more likely to experience inflation, political turmoil and rapid changes in economic conditions than more developed markets. Emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risk associated with custody of securities.
China Risk. The Fund may invest in instruments that provide exposure to Chinese companies, including through investments in China A-Shares, which would subject the Fund to risks specific to China. China may be subject to considerable degrees of economic, political and social instability.
Consumer Discretionary Sector Risk. Consumer discretionary companies, such as retailers, media companies and consumer services companies, provide non-essential goods and services. These companies manufacture products and provide discretionary services directly to the consumer, and the success of these companies is tied closely to the performance of the overall domestic and international economy, interest rates, competition and consumer confidence. Success depends heavily on disposable household income and consumer spending. Changes in demographics and consumer tastes can also affect the demand for, and success of, consumer discretionary products in the marketplace.
Industrials Sector Risk. The value of securities issued by companies in the industrials sector may be adversely affected by supply and demand changes related to their specific products or services and industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. Global events, trade disputes and changes in government regulations, economic conditions and exchange rates may adversely affect the performance of companies in the industrials sector. Companies in the industrials sector may be adversely affected by liability for environmental damage and product liability claims. The industrials sector may also be adversely affected by changes or trends in commodity prices, which may be influenced by unpredictable factors. Companies in the industrials sector, particularly aerospace and defense companies, may also be adversely affected by government spending policies because companies in this sector tend to rely to a significant extent on government demand for their products and services.
Information Technology Companies Risk. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments, frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Information technology companies are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action.
Variable Interest Risk. Exposure to VIEs may pose additional risks because the investment is made in reference to an intermediary shell company that has entered into service and other contracts with the underlying Chinese operating company to provide investors with exposure to the operating company, but does not represent equity ownership in the operating company. As a result, such investment may limit the rights of an investor with respect to the underlying Chinese operating company. VIEs allow foreign shareholders to exert a degree of control over, and obtain economic benefits arising from, the operating company without formal legal ownership. However, the contractual arrangements between the shell company and the operating company may not be as effective in providing operational control as direct equity ownership, and a foreign investor's rights may be limited by, for example, actions of the Chinese government which could determine that the underlying contractual arrangements on which control of the VIE is based are invalid. The contractual arrangement on which the VIE structure is based would likely be subject to Chinese law and jurisdiction, which could raise questions about how recourse is sought. Investments through VIEs may be affected by conflicts of interest and duties between the legal owners of the VIE and the stockholders of the listed holding company, which could adversely impact the value of investments. VIEs are not formally recognized under Chinese law and investors face uncertainty about future actions by the Chinese government that could significantly affect the operating company’s financial performance and the enforceability of the contractual arrangements underlying the VIE structure. Prohibitions of these structures by the Chinese government, or the inability to enforce such contracts, from which the shell company derives its value, would likely cause the VIE-structured holding(s) to suffer significant losses, and in turn, adversely affect the Fund’s returns and net asset value.
Concentration Risk. The Fund is concentrated in the industry or group of industries comprising the industrials, information technology and consumer discretionary sectors, collectively. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in the securities and/or other assets of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector, market segment or asset class.
Non-Diversification Risk. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds.
New Fund Risk. The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.
