Arm Quickly Denies: No Chip Manufacturing! Is the Billion-Dollar Ecosystem Stable?

“We are not a chip manufacturer!” On November 5, Drew Henry, Arm’s Executive Vice President of Strategy and Ecosystem, poured cold water on the chip industry that had been boiling for three months. From the stock price plummeting 8.65% in July after rumors of self-developed chips, to the grand recruitment of Amazon’s AI chip head in August for research and development, and now the clear denial of “entering the car manufacturing business,” this giant, which controls 99% of the global smartphone chip architecture, has finally reassured the market. Behind this “self-made chip controversy” lies Arm’s survival philosophy in the AI era — rather than being an “athlete,” it prefers to sit firmly in the roles of “referee + coach.”

1. The Dramatic Turn: From “Self-Development Rumors” to “Emergency Denial” in 90 Days

Arm’s public relations storm can be described as the “annual suspense drama” of the semiconductor industry. Rewinding the timeline three months, the plot twists faster than flipping a book:

• July “Thunder”: CEO René Haas hinted at investing in self-developed chips, causing the market to explode — this meant Arm would transform from an IP vendor selling design blueprints to a direct competitor of clients like Qualcomm and Apple, leading to an 8.65% drop in after-hours stock price;

• August “Solid Evidence”: Arm offered a staggering annual salary of $25 million to recruit Rami Sinno, the former director of Amazon’s AI chip division, to lead the self-development project, prompting the outside world to exclaim, “They are determined to cross over;”

• November “Reversal”: Drew Henry publicly denied “chip manufacturing,” emphasizing “focus on collaborative design with customers,” bringing three months of speculation back to square one.

“This operation is more brain-burning than chip design,” a semiconductor analyst from a brokerage lamented, “Just after hiring a ‘chip guru,’ they say they won’t make chips. What is Arm playing at?” The answer lies in a set of data: Arm’s current revenue is only $1.05 billion, with an operating profit margin of 11%, while its client Nvidia’s quarterly revenue reaches $18.1 billion — rather than competing for scraps, it is better to maintain a business model of “sitting back and collecting money.”

2. The Confidence of Not Making Chips: An Ecological Moat Built on 300 Billion Chips

Arm’s bold claim of “not making chips” is not mere bravado, but rather a result of an ecological barrier built on 300 billion chips. Since its establishment, it has adhered to a model of “selling blueprints, not chips,” and now this “blueprint” has become the industry’s common language:

• Absolute Control in the Smartphone Realm: Out of every 100 smartphones globally, 99 use Arm architecture chips, with Apple’s A series, Qualcomm Snapdragon, and Huawei Kirin all being its “descendants;”

• A New Baseline in the AI Era: By the end of 2025, there will be over 100 billion Arm devices with AI capabilities globally, covering everything from data center servers to smart cars, all under its ecological umbrella;

• A Trillion-Level Community of Interests: Alibaba Cloud is developing cloud-native processors based on Arm architecture, Lenovo is betting on the Windows on Arm strategy, and XPeng Motors’ in-car chips also rely on its technical support, forming a “defensive network” of 30 ecological partners.

This is akin to Microsoft not making its own computers and Google not producing its own phones — Arm’s core value lies in enabling all manufacturers to use its “operating system.” If it were to start making chips, it would fall into the awkward position of being both “referee and athlete”: Qualcomm would worry about biased technology, and Apple might accelerate its self-developed architecture, potentially collapsing the ecological empire supported by 300 billion chips. “Just like an old Chinese medicine practitioner wouldn’t open a pharmacy to compete with his apprentices, one cannot destroy their own rice bowl,” an industry insider pointed out.

3. The Truth Lies in the Details: “Collaborative Design” is More Powerful than “Self-Made Chips”

What Drew Henry refers to as “collaborative design” is not merely about “helping customers modify blueprints,” but rather a more sophisticated “invisible control technique” than self-developed chips. This approach avoids direct competition with customers while tightening the grip on technological discourse:

• Binding Customers with “Semi-Finished Products”: Arm’s Computing Subsystem (CSS) essentially pre-fabricates the “core modules” of chip design, allowing customers to simply do “assembly and debugging.” This not only lowers the R&D threshold for customers but also makes them reliant on Arm’s technical framework, which is why Qualcomm once sued Arm for “indirect competition;”

• Locking in the Ecosystem with a “Software Ecosystem”: Arm provides development tools from cloud to edge for 20 million developers globally. Whether for AI smartphones or smart cars, the more developers rely on its software, the harder it becomes for customers to switch architectures. This strategy is ten times more effective than making chips — after all, no one would easily give up a mature development ecosystem;

• Fighting AI Hard Battles with “Partners’ Hands”: Hiring Rami Sinno is not about making chips, but rather leveraging his experience with Amazon’s AI chips to help Arm optimize architectural design and then output solutions to clients like Alibaba Cloud and Nvidia. It’s akin to “teaching apprentices to win battles while collecting tuition fees.”

Data speaks volumes: In the first quarter of 2025, while Arm’s revenue is only $1.05 billion, the global shipment of chips based on its architecture has exceeded 300 billion. “Rather than earning $1 from chip profits, it’s better to let customers earn $10 and then share $1 in licensing fees.” This is the essence of Arm’s business strategy.

4. The Life-and-Death Exam of the AI Era: To Uphold Ecology or Cross Over for Scraps?

Arm’s denial essentially answers the “soul-searching question” of the AI era: Should IP vendors cross over as Nvidia and AMD profit immensely from AI chips? The answer lies in two “cautionary tales”:

• Nvidia’s “Failure Lesson”: In 2020, Nvidia attempted to acquire Arm to consolidate “architecture licensing + chip manufacturing” but was ultimately blocked by global regulatory agencies — everyone fears a monopoly;

• Qualcomm’s “Dilemma”: Qualcomm both designs chips and makes terminals, leading smartphone manufacturers to increasingly support MediaTek, resulting in repeated market share setbacks. “Being both a supplier and a competitor will eventually lead to being abandoned by customers.”

For Arm, the opportunity in the AI era lies not in chip manufacturing but in “defining the rules of AI chips.” A high-bandwidth memory required for an AI training server can reduce power consumption by 40% compared to traditional architectures when designed based on Arm architecture; this technological advantage is its foundation. Now, by “collaborative design,” it helps customers optimize AI chips, allowing it to share in the AI wave’s benefits without disrupting ecological balance, which is much smarter than entering the chip manufacturing arena.

5. Market Impact: Which Players Should Rejoice?

Arm’s declaration of “not making chips” has relieved three types of companies and pointed the market towards investment directions:

• Arm’s “Loyal Customers” are the Most Reassured: Qualcomm and MediaTek no longer need to worry about “the master stealing business” and can confidently increase their investment in Arm architecture; although Apple is developing its own architecture, it still relies on Arm’s ecological support in the short term, making cooperation between the two more stable;

• Ecological Partners Enter a “Honeymoon Period”: Companies like Alibaba Cloud and Lenovo, which are betting on Windows on Arm, no longer need to worry about Arm’s “bias” and will be more proactive in promoting Arm-based product launches. Arm’s Vice President for China, Zou Ting, revealed that innovations from Chinese partners in AI smartphones and smart cars are accelerating;

• “Water Sellers” in the Industry Chain Continue to Benefit: Companies providing EDA tools for Arm, such as Synopsys and Cadence, as well as domestic firms adapting Arm architecture like Zhongke Chuangda, will receive more orders as Arm’s ecosystem expands. After all, the more successful Arm’s “collaborative design” becomes, the greater the demand for these supporting services.

Of course, risks cannot be ignored: if Arm’s “collaborative design” cannot keep pace with the iteration speed of AI chips, customers may turn to open-source architectures like RISC-V. However, from the current perspective, the goal of equipping 100 billion AI devices globally has added sufficient water to Arm’s ecological moat.

This “self-made chip controversy” has come to an end, with Arm using a denial to safeguard its ecological foundation. In the semiconductor industry, there has never been a myth of “monopolizing everything” — Nvidia earns money from chips while Arm earns from architecture, which reflects the wisdom of division of labor in the tech industry. For investors, rather than worrying about whether Arm will make chips, it is better to focus on those companies deeply tied to the Arm ecosystem — after all, in an empire supported by 300 billion chips, those who “sell shovels” are always more stable than those who “mine for gold.”

Truly mastering the initiative.
