Behind the scenes of every chipmaker, there’s a set of instructions that dictates how their products will function. Over the last three decades, Arm has become the dominant company making this chip architecture, and it powers nearly every smartphone today. Apple bases its custom silicon for iPhones and MacBooks on Arm, and now Nvidia and AMD are reportedly making Arm-based PC chips, too.
Arm’s blockbuster IPO in September valued it above $54 billion, thanks in part to the growing list of companies choosing Arm over Intel‘s rival x86 architecture.
On Wednesday, it beat Wall Street expectations in its first post-IPO earnings report, with revenue up 28% on an annual basis during the quarter. Still, revenue guidance fell short of expectations, sending Arm shares down more than 7% in extended trading.
The UK-based company sells licenses for its chip architecture to companies that make central processing units, or CPUs. It also collects royalties on every chip shipped with its technology. Haas says that number topped 30 billion last year.Its customers are the biggest names in tech and chips, including Apple, Nvidia, Google, Microsoft, Amazon, Samsung, Intel and Taiwan Semiconductor Manufacturing Company.
“Most people think about a device. Then maybe if they’re really sophisticated, they think about the chip, but they don’t think about the company that came up with the original ideas behind how that chip operates,” said Bob O’Donnell, president and chief analyst at TECHnalysis Research. “But once you do understand what they do, it’s absolutely amazing the influence they have.”
Arm enables chips to use less power than those made with x86. Lately, it’s seen a big surge in adoption.
Arm is the basis for Apple’s custom processors, which have replaced Intel chips in Macs. Amazon Web Services bases its custom server chips on Arm. Qualcomm’s flagship Snapdragon chips are also Arm-based, and getting ready to make a meaningful move into the PC market.
But Arm has also faced plenty of risks in recent years. About 20% of its revenue comes from China, according to the company. Smartphones, which almost all contain Arm processors, are seeing a major sales slump. And when Nvidia tried to buy Arm for $40 billion, the deal was blocked by regulators last year.
“That didn’t go the way that everyone anticipated or hoped that it would. But the sun comes up the next day, right? And you have to be able to build from that,” CEO Rene Haas told CNBC in an interview in October.
CNBC went to Arm’s headquarters in Cambridge, England, to find out how it became the year’s biggest IPO despite struggling smartphone sales and geopolitical uncertainty.
From smartphones to AI
Arm was founded in 1990 by 12 chip designers working out of a turkey barn in Cambridge. It was originally a joint venture between Apple, Acorn Computers, and VLSI, which is now part of NXP.
Arm’s big break came in 1993, when Apple launched its early handheld Newton device on the Arm610 processor. Haas said this gets at the “hallmarks” of the company. “We were born running a device off a battery that was going to be low cost,” he said.
Arm’s big break came in 1993 when Apple released its handheld Newton device on the Arm610 processor.

That same year, Arm struck a deal with Texas Instruments, putting its processors in early Nokia mobile phones and beginning Arm’s climb to become the dominant smartphone architecture it is today. Arm went public for the first time in 1998. Chief architect Richard Grisenthwaite was there.
“We were about 100 people, and I’ve been very much involved in this tremendous transition that the company has gone through, expanding out from being targeting one particular market area into a wide range of different computing environments,” Grisenthwaite said.
Indeed, Arm grew rapidly in the 2000s, with the first touchscreen phones introduced in 2007 and the growth of connected home devices in the 2010s.
Arm now has some 6,500 employees globally. Grisenthwaite said the majority of those employees are in the UK, and about a sixth are in the U.S., where Arm has offices in Arizona, California, North Carolina and Texas. It also has locations in Norway, Sweden, France and India.
In 2016, Arm once again became a private company when Japan’s SoftBank acquired it for $32 billion. Haas was president of the IP products group at the time, spearheading diversification into emerging markets, including AI.
“PC and phone, automotive, data center and IoT. Those are the primary markets that we address. Every single one of those markets has AI embedded in some way, shape or form,” he said.
Arm has some 6,800 patents worldwide, with another 2,700 applications pending. Some of those are for Arm’s Neoverse line for high-performance and cloud computing, which has helped it break into AI since its launch in 2018.
In August, Nvidia announced its latest Grace Hopper Superchip, which couples its own GPUs with Arm’s Neoverse cores.
“By bringing those together and tightly coupling the way that Nvidia has with the Grace Hopper, they’re able to come up with something that’s something like 2 to 4 times the performance of what you’d get on an x86 system for a similar amount of power,” Grisenthwaite explained.
Cash and competition
If you rewind just a couple years, Nvidia’s interest in Arm went far beyond technology integration. Arm owner Softbank needed cash after losing money on high-profile investments in companies like WeWork and Uber. In 2020, SoftBank struck a deal with Nvidia to sell Arm for $40 billion. Eighteen months later, the deal fell apart, blocked by regulators and some of Arm’s biggest customers, which also compete with Nvidia.
Haas said he was, “Disappointed it didn’t happen just because we spent so much time on it.”
Instead, Softbank announced plans to take Arm public again and Haas took over as CEO.

Arm made its second public debut this September, climbing nearly 25% that day.
The stock has fallen significantly since then.
One risk comes from a free, open-source rival architecture called RISC-V. It’s seen a recent surge in backing from some of Arm’s big customers like Google, Samsung and Qualcomm, which may have been seeking alternatives when it looked like Nvidia was going to buy Arm.
For now, RISC-V remains a low risk competitor according to Futurum Group CEO Daniel Newman.
“RISC-V sits a few years behind where Arm is at, and I don’t think we’re going to hear a lot about it right away. I do think in low power, in IoT, in simpler designs, that RISC-V does have some traction,” Newman said.
Arm’s bigger competition comes from x86. Developed by Intel in the 70s, x86 is the dominant architecture used for PC processors, with a massive amount of software developed for it.
“The amount of software support is the thing that actually tends to determine the success or failure of that in the long run. Intel was very good early on with getting a ton of software support for x86,” O’Donnell explained.
Most servers have also traditionally been based on x86, but O’Donnell said that could shift.
“What’s happened in the server market is that the software has been componentized. It’s broken up into containers and things like that, and that makes it easier to run on other architectures like Arm,” he said.
Amazon Web Services is a big player making Arm-based server chips. AWS launched its Graviton chips to rival x86 CPUs from AMD and Intel in 2018.
“And really from there, Arm went from this mobile, low power IoT, automotive specialty embedded to holy cow, we can build next generation servers, PCs, and of course continue on this massive run of silicon for smartphones, all based on Arm,” Newman said.
‘If Apple can do it, can others?’
Apple is the big partner helping Arm break into the laptop market.
Apple moved to its own Arm-based processors in Mac computers in 2020, breaking away from the Intel x86 processors that had powered them for 15 years.
In October, Apple announced its latest line of M3 processors and the MacBooks and iMacs running on them. Apple said Arm-based M3 gives the newest MacBook up to 22 hours of battery life.
“Nobody really believed, until Apple went all in and basically cut ties with x86 instruction sets and said, ‘We are going to bet the future of the Mac on Arm.’ And that was a huge inflection for the company. It was a change of the guard. And this isn’t to say that Intel’s future is in big trouble, but it certainly started to raise some question marks as to, well, if Apple can do it, can others?” Newman said.
In September, Apple extended its deal with Arm through at least 2040.
Qualcomm is another major customer making its latest PC processors using Arm, although that relationship is strained. Arm is suing Qualcomm over the right to make certain chips with its technology. The issues started after Qualcomm acquired CPU company Nuvia in 2021, and with it, Nuvia’s Arm license.
“Nuvia was actually supposed to be designing a server chip initially, so they had different terms with them. And so Qualcomm thought they could have the same terms. Arm felt no, different companies have different terms. And it’s boiled down to essentially that: legal discussions around what those terms ought to be,” O’Donnell explained.
The case is set to go to trial in 2024.
Arm is also growing in the automotive space. Although its chips have long been in cars, it’s now a rapid growth area with the rise of self-driving capabilities and partnerships with companies like Cruise.
Arm’s Grisenthwaite calls self-driving “one of the most computationally intensive tasks we’ve ever seen on this planet.”
“What we need to provide is a standard platform to allow the world’s software developers to really concentrate on this incredibly hard task going forward,” he said, while demonstrating the AVA developer platform, which brings multiple self-driving components together to function on a single processor.
This simplification is also making Arm the choice for non-chip companies like Apple, Amazon, Google and Microsoft designing their own custom silicon.
“They’ve got a smaller team than entire companies built on that. And so you have to make that process easier and simpler. And that, for example, is where Arm is starting to move in terms of enabling the design of multiple components that connect together,” O’Donnell said.

‘China is a good market for us’
Although more companies are making inroads into semiconductor design, the recent chip shortage exposed major concern over the fact that more than 90% of the world’s chips are manufactured in Asia.
Now China and the U.S. are going back and forth imposing export controls on chip technologies. For now, Arm says it’s seen minimal impact from the export controls.
“What we do is obviously comply with all kinds of export regulations whenever they come out. Of course we comply. China is a good market for us: about 20% of our business. It’s shifted over the years. It used to be largely mobile phone based. Now it’s mostly around the data center and automotive,” Haas said.
In 2018, SoftBank broke off Arm’s China business into an independent entity, Arm China, that’s majority owned by a group of Chinese investors.
Haas explained further, “It’s essentially to allow us to not only grow our business in China, which is our essentially base core business. We set up a distributor arm, but at the same time, we also created an R&D arm that allows an independent entity to develop products specifically for the China market, some that are Arm based but some that are not Arm based.”
Arm China has also been embroiled in controversy, with SoftBank and Arm trying to oust the CEO of the China business, Allen Wu. Despite being fired, Wu refused to leave for years.
“It’s been very ugly and kind of messy and confusing,” O’Donnell said.
“A lot of Chinese companies have long standing relationships with Arm, so the expectation is they’re going to want to work there because they have that huge base of software. If somebody creates a new architecture, they have to build the software, and that takes years and years and years,” he said.
“We’re not as impacted as folks might think because one of the trends we’ve seen, particularly in smartphones, is more and more Arm processors that go into those phones,” Haas said. “So for us, we’ve actually seen an increase in royalty per phone.
“It’s hard for our whole industry because there’s no way that demand for semiconductors in the next 10 to 15 years will abate. It’s only going to increase. So it’s a pretty fierce talent war,” Haas said.

Amazon said Monday it will invest as much as $50 billion to expand its capacity to provide artificial intelligence and high-performance computing capabilities for its cloud unit’s U.S. government customers.
The project is slated to break ground in 2026 and will add nearly 1.3 gigawatts of capacity through new data centers designed for federal agencies, the company said in a blog.
As part of the investment, agencies will have access to Amazon Web Services’ AI tools, Anthropic‘s Claude family of models and Nvidia chips as well as Amazon’s custom Trainium AI chips.
The move follows similar announcements from Anthropic and Meta to expand AI data centers in the U.S. Oracle, OpenAI and SoftBank announced their Stargate joint venture in January, which aims to invest up to $500 billion in AI infrastructure in the U.S. over the next four years.
AWS said the project will enable agencies to develop custom AI solutions, optimize datasets and “enhance workforce productivity.” AWS serves more than 11,000 government agencies, Amazon said Monday.
“This investment removes the technology barriers that have held government back and further positions America to lead in the AI era,” AWS CEO Matt Garman said in a statement.
Tech companies have earmarked billions of dollars in a race to build out enough capacity to power AI services. Amazon in October boosted its forecast for capital expenditures this year, saying it now expects to spend $125 billion in 2025, up from an earlier estimate of $118 billion.
New York is 3,000 miles away from the tech hub of Silicon Valley, but in recent weeks, the state has inserted itself into the center of a fierce debate around artificial intelligence regulation.
A bipartisan super PAC called “Leading the Future” announced last week that it will target Alex Bores, a Democratic congressional candidate who has openly championed AI safety legislation in New York by promoting the the Responsible AI Safety and Education (RAISE) Act. The bill would require large AI companies to publish safety and risk protocols and disclose serious safety incidents.
“They don’t want there to be any regulation whatsoever,” Bores told CNBC’s “Squawk Box” on Monday. “What they’re saying is the fact that you dared step up and push back on us at all means we need to bury you with millions and millions of dollars.”
Leading the Future (LTF) launched in August with more than $100 million in funding, and aims to elevate “candidates who support a bold, forward-looking approach to AI,” according to a release. The group largely represents the view of the Trump administration, that federal AI laws should preempt regulations implemented by specific states, an effort mostly meant to undermine big blue states like California and New York.
The super PAC is backed by high-profile names in tech, including OpenAI President Greg Brockman, Palantir co-founder Joe Lonsdale, venture firm Andreessen Horowitz and AI startup Perplexity.
“LTF and its affiliated organizations will oppose policies that stifle innovation, enable China to gain global AI superiority, or make it harder to bring AI’s benefits into the world, and those who support that agenda,” the group said in the release.
Bores has served as a New York State Assembly member since 2023, and previously worked at several tech companies, including Palantir. He launched his congressional campaign for New York’s 12th district in October after sitting Democratic Rep. Jerry Nadler announced he would not run for reelection.
As an assemblyman, Bores co-sponsored the RAISE Act.
“I’m very bullish on the power of AI, I take the tech companies seriously for what they think this could do in the future,” Bores said on Monday. “But the same pathways that will allow it to potentially cure diseases [will] allow it to, say, build a bio weapon. And so you just want to be managing the risk of that potential.”

The RAISE Act passed in New York’s state assembly and senate in June. Democratic Gov. Kathy Hochul has until the start of the 2026 session to decide whether to sign it into law.
On Nov. 17, LTF’s leaders Zac Moffatt and Josh Vlasto announced they plan to spend millions of dollars to try to sink Bores’ congressional bid. In a statement, they accused Bores of pushing “ideological and politically motivated legislation” that would “handcuff” the U.S. and its ability to lead in AI.
The bill is “a clear example of the patchwork, uninformed, and bureaucratic state laws that would slow American progress and open the door for China to win the global race for AI leadership,” Moffatt and Vlasto told CNBC in a statement.
Moffatt has more than two decades of experience in digital and political strategy, while Vlasto previously served as press secretary to Sen. Chuck Schumer (D-NY) and chief of staff to former New York Governor Andrew Cuomo.
Politico was first to report LTF’s effort to target Bores.
Bores has capitalized on LTF’s announcement as a fundraising opportunity, urging voters to donate to his campaign if they “don’t want Trump mega-donors writing all tech policy,” he wrote in a post on X.
“I am someone with a master’s in computer science, two patents, and nearly a decade working in tech,” Bores told CNBC in a statement last week. “If they are scared of people who understand their business regulating their business, they are telling on themselves.”
What is the RAISE Act?
The RAISE Act applies to any large AI company, like Google, Meta or OpenAI, that has spent more than $100 million in computational resources to train advanced models.
It would require these companies to write, publish and follow safety and security protocols, and to update them as necessary. Violators could be subject to penalties of up to $30 million.
The companies would also have to take steps to implement safeguards to prevent their models from engaging in “critical harm,” like assisting in the creation of chemical weapons or large-scale, automated criminal activities. “Critical harm” is defined in the bill as the death or serious injury of 100 people or at least $1 billion in damages.
Under the RAISE Act, large AI companies would not be able to release models that would create “unreasonable risk of critical harm.” Bores said the bill’s opponents have pushed back fiercely on that part of the legislation.
“That’s designed to basically avoid the problem we had with the tobacco companies, where they knew that cigarettes caused cancer but denied it publicly and continued to release their products,” he said.
The RAISE Act would also require AI companies to disclose notable safety incidents. If a model is stolen by a malicious actor, for instance, its developer would have to disclose that incident within 72 hours of learning about it.
“We just saw two weeks ago, Anthropic talk about how China used their model to do a cyber attack on U.S. government institutions and our chemical manufacturing plants,” Bores said. “Shockingly, they didn’t have to disclose that. I think that should be law and be required for every major AI developer.”
Anthropic, an AI startup valued at around $350 billion after recent investments, published a blog post earlier this month detailing what it called “the first documented case of a large-scale cyberattack executed without substantial human intervention.” Anthropic said it believes the threat actor was a Chinese state-sponsored group.
Bores told Tech Brew that he drafted the initial version of the bill in August of 2024 and sent it to “all of the major developers” for feedback. He put together a second draft in December, and solicited another round of red lines.
The RAISE Act was published in March, and amended in May and June.
“I worked really closely with a lot of people in industry to get the details right,” Bores told Tech Brew.

LTF’s decision to target Bores over the RAISE Act is emblematic of a broader debate around whether AI should be regulated at the state or federal level in the U.S.
Some lawmakers and tech executives have argued that a “patchwork” of state AI policies will hinder innovation and put the U.S. at risk of falling behind its adversaries like China. But others, including Bores, have said that the federal government moves too slowly to keep up with the rapid pace of AI development.
“What’s being debated right now is, should we stop the states from making any progress before the feds have solved the problem? Or should we actually work together to have the federal government solve the problem?” Bores said.
Aside from New York, states including California, Colorado, Illinois and others have their own AI laws that are either already in effect or will be starting early next year.
Last week, President Donald Trump advocated for a federal AI standard in a post on his social media site Truth Social.
“Investment in AI is helping to make the U.S. Economy the ‘HOTTEST’ in the World, but overregulation by the States is threatening to undermine this Major Growth ‘Engine,'” Trump wrote. “We MUST have one Federal Standard instead of a patchwork of 50 State Regulatory Regimes. If we don’t, then China will easily catch us in the AI race.”
The White House also began drafting an executive order that would target state AI laws by launching legal challenges and withholding federal funding, CNBC reported on Thursday. But a day later, the Trump administration put a hold on that effort, according to a report from Reuters.
The White House didn’t provide a comment for this story.
Earlier this year, a proposed amendment to Trump’s “One Big Beautiful Bill Act” would have enacted a 10-year-long suspension on state-level AI laws. That provision ultimately failed and was not included in the legislation, but the Trump administration recently revitalized the effort.
The White House is working to see if a moratorium on certain state AI laws could be included in one of the major must-pass bills that Congress is pursuing.
“What we’re seeing in AI is natural, states are stepping up and moving quickly,” Bores said. “We should eventually have a federal AI standard. I strongly agree with that.”

Amazon said Monday it will begin allowing businesses to test its recently rebranded internet-from-space service that seeks to compete with SpaceX’s Starlink.
Select businesses will be able to test Amazon Leo production hardware and software as part of an “enterprise preview” of the service “ahead of a wider rollout,” the company said in a blog post. The test program will allow Amazon to collect feedback and “tailor solutions for specific industries” ahead of a broader launch, the company said.
Earlier this month, Amazon renamed its satellite internet offering from Project Kuiper to Amazon Leo and rolled out a new website to market the service. The name is a nod to low Earth orbit, a region of space that’s within 1,200 miles of Earth’s surface and where Amazon’s satellite constellation will be concentrated.
Six years ago, Amazon unveiled its plans to build a constellation of 3,236 low Earth satellites, designed to provide high-speed, low-latency internet to consumers, corporations and governments, offering connections through square-shaped terminals.
The company has sent up more than 150 satellites since April through a series of rocket launches handled by partners, such as United Launch Alliance and Elon Musk’s SpaceX.
It’s aiming to compete with Starlink, owned by SpaceX, which currently dominates the market and has nearly 9,000 satellites in orbit.
Amazon has inked deals with JetBlue, L3Harris and Australia’s NBN internet network, among others. Amazon said it’s shipping units of its “Pro” terminals, as well as its “Ultra” antennas, to members of its enterprise preview program.
The company on Monday showed off the final production design of its Ultra model, which will offer download speeds of up to 1 gigabit per second and upload speeds up to 400 megabits per second powered by an in-house custom silicon chip, “making it the fastest commercial phased array antenna in production.”
Amazon said it expects to expand the program to more customers as it adds coverage and capacity to the Leo network.
The company has yet to disclose pricing and availability for consumers.
