Several robotics stocks are being called “the next Nvidia” by early investors, though no single company has claimed that title definitively. Teradyne, Serve Robotics, and Harmonic Drive Systems have each attracted investor attention for different reasons—from established players entering the space to critical component suppliers positioning themselves ahead of the humanoid robotics boom. The comparison itself reflects growing confidence that the robotics sector is entering a growth phase similar to what Nvidia experienced during the AI acceleration, with some analysts drawing parallels to semiconductor suppliers that benefited from infrastructure buildouts rather than just the headline companies.
The appeal of these stocks lies in a fundamental market shift. GlobalData projects the robotics sector will expand from $76 billion in 2023 to $218 billion by 2030, representing a 14% compound annual growth rate. For investors who missed Nvidia’s gains—the chip maker is up 34.1% over the past year—there’s an intuitive appeal to finding overlooked companies positioned at an earlier stage of a comparable growth story.

Which Robotics Stocks Are Being Called “The Next Nvidia”?
The three most frequently mentioned candidates serve different parts of the robotics value chain. Teradyne operates both semiconductor test equipment and a robotics division that generated $89 million in Q4 revenue, with management targeting profitability for the robotics business in 2026. Serve Robotics focuses on autonomous last-mile delivery, a narrower but potentially high-volume use case. Harmonic Drive Systems supplies mechanical components—specifically up to 44 components per humanoid robot—making it a play on component scarcity in a supply-chain-constrained market. These three companies weren’t paired together because they compete directly.
Rather, early investors see them as capturing different layers of value creation in robotics, much like how semiconductor equipment makers (like the original nvidia competitors) benefited from AI infrastructure expansion without building the chips themselves. The “next Nvidia” label actually means something closer to “overlooked companies positioned ahead of explosive growth,” not necessarily single winners. Harmonic Drive Systems has drawn the most specific analyst enthusiasm, with target prices suggesting as much as 50% upside within 12 months. This reflects a structural bet: if humanoid robots scale as many in the industry expect, the bottleneck won’t be chip supply—it will be precision components that take years to design and manufacture at scale. One analyst noted that relying on current supply chains for 44 specialized parts per robot creates a natural windfall for suppliers who can scale production.
The Risk of Mistaken Comparisons to Nvidia
The “next Nvidia” framing carries an important caveat: Nvidia’s 34% annual return and $586 million in automotive and robotics revenue came after decades of dominance in GPUs and a perfect storm of AI tailwinds. Simply being positioned in a growing sector isn’t the same as replicating that performance. Serve Robotics, for example, lost 28.3% of its value over the past year, despite operating in a sector that grew 18.5%—a stark reminder that the “right sector” and the “right stock” aren’t synonymous. Early-stage companies in robotics face execution risk, competition from larger players, and the possibility of technological disruption. Teradyne’s robotics division, while generating real revenue, is still targeting breakeven in 2026—meaning shareholders are betting on profitability that hasn’t yet materialized.
The comparison to Nvidia works best for companies with defensible positions (like Harmonic Drive’s component dominance) rather than for startups competing in crowded delivery or general-purpose robotics spaces. The broader risk is that investor enthusiasm conflates sector growth with stock outperformance. The robotics market could grow to $218 billion while most individual stocks in the space underperform due to commoditization, competitive pressure, or better-capitalized rivals. Nvidia benefited from a unique convergence of events—first-mover advantage in GPU architecture, a de facto monopoly that lasted a decade, and the timing to capture the AI wave at scale. Robotics is following a more competitive, fragmented path.
The Humanoid Robot Bottleneck
Much of the investor excitement centers on humanoid robots, a category that’s moved from research labs to commercial prototype stage faster than many expected. Boston Dynamics, tesla Optimus, and others are demonstrating robots with useful capabilities, but they’re running into a hidden constraint: precision components. Harmonic Drive Systems manufactures harmonic drive reducers, precision gearboxes that allow robots to move with the smooth, controlled motion required for manipulation tasks. Most humanoid robots need multiple units, and global production capacity is limited. This creates a structural advantage for component suppliers that few recognize.
Unlike software or algorithms, which can be replicated infinitely and instantly, manufacturing capacity for precision components takes years and billions of dollars to build. Harmonic Drive doesn’t need to perfect robotics or compete with Tesla—it just needs to keep producing the parts that every competing robot manufacturer needs. This is the genuine appeal of the comparison to Nvidia, which benefited from being the unavoidable supplier in a high-growth infrastructure wave. The limitation is that this advantage is temporary and defensible only until competitors invest in alternative solutions. If the industry settles on different component designs, or if other suppliers enter the market with competing technologies, the bottleneck dissolves. However, the switching costs for robot manufacturers already designing around specific components create some near-term protection.
Teradyne’s Dual Exposure Strategy
Teradyne’s approach differs from component suppliers or robotics startups—it’s a diversified semiconductor equipment and manufacturing company adding a robotics division rather than betting the company on one trend. The robotics unit generated $89 million in quarterly revenue, enough to be material but not yet transformative for a company of Teradyne’s scale. This division structure creates both opportunity and constraint. The opportunity is optionality: if robotics growth accelerates, Teradyne can scale with it while retaining the stability of its core semiconductor test equipment business. The constraint is that Wall Street may never value it as a pure robotics play, limiting the upside a fully committed robotics company might capture.
Investors seeking “the next Nvidia” may overlook Teradyne simply because it’s not a focused bet on the trend. The company’s target of profitability for the robotics division in 2026 represents a near-term milestone investors can monitor. Unlike longer-dated bets on humanoid robot adoption or autonomous delivery scaling, this is a concrete financial goal. If Teradyne achieves it, it validates the division’s business model and potentially repositions the entire company in investors’ minds. If it misses, it signals that robotics scaling is slower than expected.
Why Component Suppliers Matter More Than You Think
The robotics industry’s structure resembles the semiconductor industry in one critical way: the most obvious winner (the robot maker) often captures less value than the enabling suppliers. When Tesla or Boston Dynamics deploys thousands of humanoid robots, the robot maker gets the headlines and faces intense competition. But the harmonic drive supplier, the vision system vendor, the software middleware company—these faces limited competition because they’re embedded into the design of every competing robot. This dynamic explains why Harmonic Drive’s 50% upside target is plausible within a 12-month window. If humanoid robot deployment accelerates and supply constraints bite harder, the component supplier’s stock reacts more sharply than the robot maker’s, which spreads the impact across its business.
The comparison to Nvidia holds because Nvidia saw this exact pattern: GPU demand drove massive returns not just for the chip maker but even more for the foundries and equipment makers that supplied them. The warning embedded in this insight is that component supplier valuations are fragile. They depend entirely on sustained demand from the industries they serve. If humanoid robots fail to scale, or if the industry successfully diversifies its supply chain, the value proposition collapses. There’s no consumer product to fall back on, no brand loyalty, no alternative revenue stream.
Serve Robotics and the Autonomous Delivery Wildcard
Serve Robotics represents a different bet: that autonomous last-mile delivery becomes a major logistics category. The company operates in a narrower market than general humanoid robots, but also one with near-term commercial viability. However, its 28.3% decline over the past year despite sector growth of 18.5% reflects the specific challenges of robotics startups: execution delays, regulatory uncertainty, and well-capitalized competitors entering the space.
The company has proven units in operation and real partnership agreements, but it’s pre-profitability and operating in a regulatory landscape that could shift overnight. A single city blocking autonomous delivery permits, or a major incident involving a competitor’s robot, could shift investor sentiment dramatically. This is where the “next Nvidia” comparison breaks down most clearly—Serve Robotics has the volatility of a startup and the reliance on speculative future adoption that Nvidia largely avoided by serving infrastructure demand that was already proven.
The Road Ahead for Robotics Stocks
The robotics sector’s path forward will likely determine which of these “next Nvidia” candidates actually deliver those returns. If humanoid robots scale as the industry expects, the component suppliers will likely outperform the robot makers, much as happened in semiconductors. If adoption stalls, all robotics stocks will struggle. The difference between $218 billion of sector opportunity and $76 billion of current market size depends on commercial adoption that hasn’t yet been guaranteed.
Investors should separate sector growth from stock selection. The robotics sector could double or triple in size over the next five years while most robotics stocks underperform due to competition, commoditization, or better alternatives. However, companies with defensible positions in critical supply chains—like Harmonic Drive’s role in humanoid robot joints—have genuine structural advantages that mirror Nvidia’s experience in GPU supply. The “next Nvidia” among robotics stocks probably isn’t the company making robots; it’s the company making the parts every robot maker must use.
Conclusion
Multiple robotics stocks are being called “the next Nvidia” by early investors, but the comparison works best for component suppliers like Harmonic Drive Systems than for robot makers or autonomous delivery startups. The robotics sector is genuinely set to expand dramatically—from $76 billion today to an estimated $218 billion by 2030—but sector growth doesn’t automatically translate into stock returns. Early investors are attracted to companies positioned at different levels of the value chain, from established players like Teradyne adding robotics divisions to pure-play suppliers and startups. The real lesson from comparing robotics stocks to Nvidia is structural rather than about a specific winner.
Nvidia’s dominance came from being the unavoidable supplier of essential infrastructure during a growth wave. Robotics stocks that replicate this role—controlling production of critical components that every competing robot requires—have the clearest path to outsized returns. Startups and generalist robotics companies face far steeper competition and execution risk. For investors exploring the “next Nvidia,” examining the supply chain position matters more than the company’s headline category.
