Serve Robotics（SERV）股票深度分析：Physical AI 赛道前景如何？

In 2026, Physical AI is moving from proof of concept to large-scale commercial deployment. In this wave of entity intelligence driven by autonomous driving technology, Serve Robotics (NASDAQ: SERV), with its sidewalk autonomous delivery robots at the core, is gradually building a cross-scenario robot platform covering food delivery, medical logistics, and software services. As of June 25, 2026, SERV's stock was trading around $6.10, with a market cap of approximately $472 million, up about 38.25% year-to-date, but down about 67% from its 52-week high of $18.64.

Why Physical AI Has Become a New Narrative Focus for Capital Markets

Physical AI refers to a technological paradigm that combines artificial intelligence algorithms with physical entities (such as robots and autonomous vehicles), enabling machines to autonomously perform tasks in the real world. Unlike generative AI, which focuses on digital content creation, Physical AI directly acts on the physical space, and its commercialization path involves the coordination of multiple technology layers, including hardware manufacturing, real-time perception, motion control, and edge computing.

Serve Robotics is at the forefront of this track. The company develops and operates autonomous sidewalk delivery robots, focusing on transforming last-mile logistics for restaurants, retail, and grocery brands. As of the first quarter of 2026, Serve had deployed approximately 2,000 robots across 44 cities in 14 U.S. states, completing nearly 2 million deliveries cumulatively. This scale makes it the largest operator of sidewalk autonomous delivery fleets in the United States.

The market space for Physical AI is vast. According to industry research estimates, the global last-mile delivery market has a potential size of hundreds of billions of dollars, and sidewalk robot delivery, as one of the most cost-competitive solutions, is attracting continuous investment from platform giants including Uber and DoorDash.

Is the 578% Revenue Surge Backed by Sustainable Growth Logic

Serve Robotics' financial performance in the first quarter of 2026 drew widespread market attention. The company reported revenue of approximately $3 million, up 578% year-over-year and 238% quarter-over-quarter. This figure already exceeded the company's total revenue of $2.7 million for the full year of 2025.

In terms of revenue composition, fleet services revenue was about $1.96 million, up nearly tenfold year-over-year; software services revenue was about $1 million, accounting for roughly one-third of quarterly total revenue. Management specifically noted that approximately $1.4 million of the quarter's revenue was recurring, making up nearly half of total revenue. This data indicates that the company is transitioning from a pure hardware deployment model to a platform-based, software-oriented revenue structure.

However, the rapid revenue growth has not translated into improved profitability. In the first quarter of 2026, the company reported a net loss of $49 million, significantly widening from $13.2 million in the same period last year. The gross margin was negative 302%, with fleet operations generating negative gross margins due to ongoing expansion, while software services maintained positive gross margins. The coexistence of surging revenue and expanding losses constitutes the most critical financial contradiction for Serve Robotics today—the cost of scaling remains high.

From 2,000 Robots to the Economic Model Per Robot

Serve Robotics achieved its goal of deploying 2,000 robots in 2025, becoming the scale leader in the U.S. sidewalk delivery space. Entering 2026, the company's strategic focus has shifted significantly—from "increasing robot count" to "improving output efficiency per robot."

Operational data shows the initial results of this shift. In the first quarter of 2026, the average daily active robots reached 812, up about tenfold year-over-year; average daily supply hours exceeded 10,000, up about thirteenfold year-over-year. In other words, while the fleet size expanded, both the activation rate and average daily operating hours per robot improved simultaneously.

Notably, management clearly stated that in the first half of 2026, no new sidewalk robots will be deployed, with focus shifting to operational work such as merchant activation, platform integration, and regional coverage. CEO Ali Kashani reminded during the earnings call that investors should not expect the same growth rate every quarter, and growth is expected to slow in the second quarter. This strategic adjustment reflects the company's phase shift from "broad expansion" to "precision operations"—the key is whether the 2,000 deployed robots can achieve improved unit economics at the current scale.

How the Acquisition of Diligent Robotics Expands the Application Boundaries of Physical AI

In January 2026, Serve Robotics acquired Diligent Robotics for $29 million in an all-stock transaction, expanding its business from sidewalk delivery to indoor service robots in hospitals. Diligent's core product, the Moxi robot, can perform logistical tasks such as transporting items and restocking supplies within hospitals, helping healthcare workers reduce repetitive labor burdens.

This acquisition has multiple strategic implications. First, the medical robot market is highly repetitive and sticky, conducive to forming stable recurring revenue streams—medical automation already constitutes a significant part of the approximately $1.4 million in recurring revenue in Q1 2026. Second, although the hospital environment differs from sidewalks, both require robots to operate safely and reliably in complex spaces with dense human traffic, providing Serve's autonomous navigation technology stack with cross-scenario validation and data accumulation.

The effectiveness of post-acquisition integration will be an important dimension for market evaluation of Serve's long-term value. If Diligent can grow from an acquired medical robotics company into a scalable extension of Serve's autonomous platform, medical automation could become a second growth curve on par with food delivery in the future.

Can Software and Services Revenue Become a Key Variable for Gross Margin Improvement

Against the backdrop of ongoing negative gross margins in fleet operations, the profit structure of software services is particularly important. In Q1 2026, software revenue was about $1 million, accounting for one-third of total quarterly revenue, with positive software gross margins. This comparison clearly shows that scaling software services is the most direct path to improving the company's overall gross margin.

Serve is advancing multiple software monetization initiatives. Its connectivity platform enables robots deployed in various locations to maintain reliable internet connections and receive remote support when needed, with external customers already using the service. Additionally, the company's ongoing investments in AI models, fleet software, and data infrastructure are laying the foundation for broader platform services.

Management's goal is to continuously increase the share of software services in total revenue. If this trend continues, the company may gradually improve operating leverage and profit margins while maintaining rapid revenue growth. However, it should be noted that the current software revenue base of about $1 million is still small, and there is still a long way to go before it becomes a major revenue source capable of offsetting fleet operation losses.

How the Coopetition Relationship with Uber and DoorDash Defines Serve's Market Space

Serve Robotics does not build a delivery platform directly facing consumers; instead, it obtains order flow through partnerships with large delivery platforms like Uber and DoorDash. This "technology supplier + platform partner" business model gives Serve a lightweight market expansion capability but also makes it highly dependent on a few partners on the demand side.

In terms of partnership progress, DoorDash's merchant count has grown about sixfold since early 2026, and Serve's delivery volume through DoorDash is growing faster than through other partners. Uber, meanwhile, has over 30 autonomous driving partners and expects to operate autonomous driving services in up to 15 cities by the end of 2026.

However, competitive pressure cannot be ignored. Uber and DoorDash are both actively building their own or partnered autonomous delivery capabilities. If these platform giants ultimately choose to build their own sidewalk delivery fleets or cooperate with other robot suppliers, the substitution risk for Serve would significantly increase. Currently, Serve's competitive advantage lies in its deployed fleet of 2,000 robots and the accumulation of actual operational data—these constitute competitive barriers that are difficult to replicate quickly in the Physical AI track.

Where Does the Core of Valuation and Market Divergence Lie

As of June 25, 2026, SERV's stock price was around $6.10, down about 67% from its 52-week high of $18.64. The stock has risen about 38.25% year-to-date but has fallen about 38.3% over the past year. There is significant divergence in market pricing of Serve Robotics.

The bullish logic mainly revolves around the following points: The full-year 2026 revenue guidance is $26 million, nearly ten times that of 2025; the company occupies a unique "pure-play" position in the Physical AI track; the 2,000 deployed robots form a monetizable tangible asset base; the medical robot acquisition has opened a new revenue stream.

The bearish logic focuses on: Q1 net loss of $49 million far exceeded revenue for the same period; the company expects non-GAAP operating expenses of $160 million to $170 million in 2026; the 2026 loss per share estimate has expanded from $2.39 to $2.58; the company's fundraising through equity issuance brings continuous dilution pressure. As of the end of Q1, the company held approximately $197 million in cash and marketable securities. At the current cash burn rate, how long this reserve can sustain operations is a closely watched metric by the market.

Summary

Serve Robotics (SERV) is at a critical stage of Physical AI commercialization. The company posted impressive revenue growth of 578% year-over-year in Q1 2026, with a fleet of 2,000 sidewalk robots giving it a leading position in the U.S. market. The acquisition of Diligent Robotics extends the business into medical automation, while the growth of software services revenue provides a potential path for gross margin improvement. However, the quarterly net loss of $49 million, ongoing cash burn, and equity dilution risk constitute core resistance to market revaluation. Serve Robotics' long-term value will depend on the realization of two key variables: whether the unit economics of the deployed fleet can substantially improve in the second half of 2026, and whether software and medical revenue can significantly enhance overall gross margins as they scale.
