Arm, which is owned by SoftBank, filed for its initial public offering Monday. The firm’s stock market debut will be a major test for the IPO market, which has more or less closed off from new listings due to rising interest rates which have hammered appetite for risky assets in the last year or so.
Arm is one of the most important companies in technology. Its chip designs found in nearly all the world’s smartphones, including Apple iPhones and most Android devices. Its debut will be a big deal for an IPO market that’s been in the doldrums since 2022, but the company’s listing has big implications for SoftBank as well.
SoftBank has been attempting to bounce back from a grim tech market by reining in on its growth-focused investments and pivoting its focus to artificial intelligence, the hot topic of the hour in tech.
What is Arm?
Arm, which is headquartered in Cambridge, England, designed the architecture of chips found in 99% of all smartphones.
The company traces its history to an early computing company known as Acorn Computers. In 1990, Acorn spun out a new company named Advanced RISC Machines, structured as a joint venture between Acorn, Apple and U.S. chipmaker VLSI Technology.
Arm isn’t a chipmaker itself. Rather, the company is responsible for coming up with the “architectures” — or overall designs, including components and programming language instructions that other companies use to build chips. Its original value was designing chips with extremely low energy consumption compared with the X86 chips common in personal computers at the time. It’s seen as something of a neutral party or “Switzerland” in tech, since its designs are used in nearly smartphone processors, including those made by Apple, and increasingly, server and laptop processors as well.
It’s also often considered the crown jewel of the U.K.’s technology sector.
Speaking with CNBC at a developer conference in October 2022, Arm CEO Rene Haas said that companies can’t afford not to work with the company, given its technology is embedded in virtually every device out there.
“Given the fact that we license the technology to all the major players in the industry, no one can really afford to miss a product cycle or scale back on R&D or not do a product,” Haas said at the time.
Arm’s business model is to license the intellectual property for these architectures so that they can build systems around them. In recent years, ARM has tried to sell its own designs for processors, a more lucrative business than just licensing the underlying architecture technology.
SoftBank agreed to acquire Arm in 2016 for $32 billion, which at the time was the biggest-ever purchase of a European technology company. SoftBank at the time said it was acquiring the business to gain a foothold in the growing internet of things sector. IoT, is a small part of the firm’s business, but at the time it was a much-hyped part of tech.
Not just for wearables or smart home appliances, Arm has been expanding its semiconductors to other uses such as connected cars.
For the quarter ended June 30, the company generated 88.5 billion Japanese yen ($605.5 million), according to an earnings release from SoftBank.
But the company is also facing headwinds from a slowdown in demand for products like smartphones, which has hit chip firms across the board. Arm’s net sales fell 4.6% year-on-year in the second quarter.
The unit also swung to a 9.5 billion yen loss, having made a profit of 29.8 billion yen in the same period a year earlier.
Beleaguered sale to Nvidia
SoftBank originally tried to sell Arm to chip giant Nvidia, but the deal faced pushback from regulators, who raised concerns over competition and national security. Nvidia is a behemoth in the world of semiconductors, and the company is now benefiting heavily from the boom in AI applications as demand for its GPUs soars.
Since then, SoftBank has opted to list Arm as an independent company. The Japanese tech investing giant is reportedly looking to purchase the remaining 25% stake in Arm that it does not currently own from its massive $100 billion Vision Fund.
In the U.K., which has sought to boost its domestic chip industry through up to £1 billion ($1.3 billion) in investments, Arm is seen as strategically important.
The change of the company’s ownership to foreign hands is seen as a thorny topic for the domestic tech industry, not least due to concerns that it undermines the U.K.’s “tech sovereignty,” an issue that has cropped up throughout Europe as officials look to reduce dependence on technology from the U.S. and other nations.
The government had pushed aggressively for Arm to list in London, however the company opted to go with New York for its debut instead, dealing a blow to the London stock exchange.
Testing a choppy IPO market
SoftBank is pushing ahead with a listing of Arm even as U.S. markets have been in an unsteady state. Technology valuations have fallen sharply from the peak of the 2021 tech boom.
That year, shares of newly minted public companies such as Palantir and UiPath rose to seismic levels as investors grew excited by their growth prospects in the boom times.
Arm filed confidentially for a listing in the U.S. earlier this year. It’s not yet clear what valuation SoftBank is seeking for Arm, however reports have pegged the prospective market value at between $60 billion and $70 billion.
As well as being a bellwether for the chip industry, Arm plays a role in the AI space — and is increasingly touting itself as an AI company. Investors will be watching out for the company’s S-1 filing to see how it sees the technology benefiting its business over time.
In May, Arm unveiled two new chipsets targeted at machine learning applications. One, a new CPU called Cortex-4, is a chipset that delivers faster machine-learning performance and consumes 40% less power than its predecessor, according to Arm. The other, a GPU called G720, offers better performance and uses up 22% less memory bandwidth than its predecessor, Arm said.
“Arm remains committed to developing and testing our GPUs against new applications for machine learning (ML),” the company said in a May 29 blog post announcing the products.
High-powered chips such as those offered by Nvidia and AMD are crucial to AI applications, which require lots of computing power to run smoothly. Earlier this month, Nvidia unveiled its new Grace Hopper chip for generative AI applications, which is based on Arm architecture.
SoftBank is banking on the growth in AI to lift the prospects of its Vision Fund, which has flagged in tandem with souring bets on firms like WeWork, China’s ride-hailing giant Didi Global, and Uber, the latter of which the Vision Fund has since shed its holdings.
SoftBank’s CFO Yoshimitsu Goto said during the company’s June quarter earnings call that the company has been “carefully and slowly emerging back to investment activity,” with a focus on AI investments.
SoftBank said its Vision Fund booked an investment gain of 159.8 billion yen, its first gain in five consecutive quarters. SoftBank said the fund mainly benefited from investments in its own subsidiaries — including Arm.
That still came after SoftBank’s Vision Fund reported a record 4.3 trillion yen loss in the fiscal year ending Mar. 31.
The Japanese tech giant has been starting to talk up its investments in AI recently. In July, the company led a $65 million investment in U.K. insurance technology company Tractable.

Chip giant Nvidia pushed back Sunday in response to allegations from Chinese state media that its H20 artificial intelligence chips are a national security risk for China.
Earlier in the day, Reuters reported Yuyuan Tantian, an account affiliated with Chinese state broadcaster CCTV, said in an article published on WeChat that the Nvidia H20 chips are not technologically advanced or environmentally friendly.
“When a type of chip is neither environmentally friendly, nor advanced, nor safe, as consumers, we certainly have the option not to buy it,” the Yuyuan Tantian article reportedly said, adding that the article said chips could achieve functions including “remote shutdown” through a hardware “backdoor.”
In response, a Nvidia spokesperson told CNBC that “cybersecurity is critically important to us. NVIDIA does not have ‘backdoors’ in our chips that would give anyone a remote way to access or control them.”
Nvidia on Tuesday similarly rejected Chinese accusations that its AI chips include a hardware function that could remotely deactivate the chips, also known as a “kill switch.”
Tensions between the U.S. and China on semiconductor export controls have escalated in recent weeks, even after Nvidia resumed sales of its H20 chip to China. Chinese state media has framed the H20 chip as inferior and dangerous compared to Nvidia’s other chips, while the company has defended its chips.
The company’s resumption of its H20 shipments reversed a previous ban on H20 sales that was placed in April by the Trump administration. Nvidia’s H20 chips — a less-advanced semiconductor compared to its flagship H100 and B100 chips, for example — were developed by Nvidia for the Chinese market after initial export restrictions on advanced AI chips in late 2023.
U.S. export controls on some Nvidia chips are rooted in national security concerns that Beijing could use the more advanced chips to gain an advantage broadly in AI, as well as in its military applications.

Chinese officials, meanwhile, are pushing for the U.S. to ease export controls on high-bandwidth memory chips as part of a trade deal before a possible summit between U.S. President Donald Trump and Chinese President Xi Jinping, the Financial Times reported on Sunday, citing people familiar with the matter.
Nvidia CEO Jensen Huang has supported Trump’s policies while also lobbying for export licenses for the H20 AI chip. Huang has said he wants Nvidia to ship more advanced chips to China, underscoring his outspoken stance that Nvidia’s chips becoming the global standard for AI computing is ultimately better for the U.S. to retain market dominance and influence over global AI development.
China is among Nvidia’s largest markets. Nvidia took a $4.5 billion writedown on its unsold H20 inventory in May and has warned that its topline guidance for the July quarter would have been higher by $8 billion without the chip export restrictions.
Nvidia shares were up 1% to close at $182.70 on Friday and are up 36% this year.

Apple shares rose 13% this week, its largest weekly gain in more than five years, after CEO Tim Cook appeared with President Donald Trump in the White House on Wednesday.
Shares of the iPhone maker rose 4% to close at $229.35 per share on Friday for the company’s largest weekly gain since July 2020. The week’s move added over $400 billion to Apple’s market cap, which now sits at $3.4 trillion.
Apple is the third-most valuable company, behind Nvidia and Microsoft and ahead of Alphabet and Amazon.
At the White House on Wednesday, Cook appeared with Trump to announce Apple’s plans to spend $100 billion on American companies and American parts over the next four years.
Apple’s plans to buy more American chips pleased Trump, who said during the public meeting that because the company was building in the U.S., it would be exempt from future tariffs that could double the price of imported chips.
Investors had worried that some of Trump’s tariffs could substantially hurt Apple’s profitability. Apple warned in July that it expected over $1 billion in tariff costs in the current quarter, assuming no changes.
“Apple and Tim Cook delivered a masterclass in managing uncertainty after months and months of overhang relative to the potential challenges the company could face from tariffs,” JP Morgan analyst Samik Chatterjee wrote on Wednesday. He has an overweight rating on Apple’s stock.
Cook’s successful White House meeting also comes two weeks after Apple reported June quarter earnings in which overall revenue jumped 10% and iPhone sales grew by 13%.

Tesla has been granted a permit to run a ride-hailing business in Texas, allowing the electric vehicle maker to compete against companies including Uber and Lyft.
Tesla Robotaxi LLC is licensed to operate a “transportation network company” until August 6, 2026, according to a listing on the website of the Texas Department of Licensing and Regulation, or TDLR. The permit was issued this week.
Elon Musk’s EV company has been running a limited ride-hailing service for invited riders in Austin since late June. The select few passengers have mostly been social media influencers and analysts, including many who generate income by posting Tesla fan content on platforms like X and YouTube.
The Austin fleet consists of Model Y vehicles equipped with Tesla’s latest partially automated driving systems. The company has been operating the cars with a valet, or human safety supervisor in the front passenger seat tasked with intervening if there are issues with the ride. The vehicles are also remotely supervised by employees in an operations center.
Musk, who has characterized himself as “pathologically optimistic,” said on Tesla’s earnings call last month that he believes Tesla could serve half of the U.S. population by the end of 2025 with autonomous ride-hailing services.
The Texas permit is the first to enable Tesla to run a “transportation network company.” TDLR said Friday that this kind of permit lets Tesla operate a ride-hailing business anywhere in the state, including with “automated motor vehicles,” and doesn’t require Tesla to keep a human safety driver or valet on board.
Tesla didn’t immediately respond to a request for comment.
As CNBC previously reported, Tesla robotaxis were captured on camera disobeying traffic rules in and around Austin after the company started its pilot program. None of the known incidents have been reported as causing injury or serious property damage, though they have drawn federal scrutiny.
In one incident, Tesla content creator Joe Tegtmeyer reported that his robotaxi failed to stop for a train crossing signal and lowering gate-arm, requiring a Tesla employee on board to intervene. The National Highway Traffic Safety Administration has discussed this incident with Tesla, a spokesperson for the regulator told CNBC by email.
Texas has historically been more permissive of autonomous vehicle testing and operations on public roads than have other states.
A new law signed by Texas Republican Gov. Greg Abbott goes into effect this year that will require AV makers to get approval from the state before starting driverless operations. The new law also gives the Texas Department of Motor Vehicles the authority to revoke permits if AV companies and their cars aren’t complying with safety standards.
Tesla’s AV efforts have faced a number of challenges across the country, including federal probes, product liability lawsuits and recalls following injurious or damaging collisions that occurred while drivers were using the company’s Autopilot and FSD (Full Self-Driving) systems.
A jury in a federal court in Miami last week determined that Tesla should hold 33% of the liability for a fatal Autopilot-involved collision.
And the California DMV has sued Tesla, accusing it of false advertising around its driver assistance systems. Tesla owners manuals say the Autopilot and FSD features in their cars are “hands on” systems that require a driver ready to steer or brake at any time. But Tesla and Musk have shared statements through the years saying that a Tesla can “drive itself.”
Since 2016, Musk has been promising that Tesla would soon be able to turn all of its existing EVs into fully autonomous vehicles with a simple, over-the-air software update. In 2019, he said the company would put 1 million robotaxis on the road by 2020, a claim that helped him raise $2 billion at the time from institutional investors.
Those promises never materialized and, in the robotaxi market, Tesla lags way behind competitors like Alphabet’s Waymo in the U.S. and Baidu’s Apollo Go in China.
Tesla shares are down 18% this year, by far the worst performance among tech’s megacaps.
