US FTC reportedly launches antitrust probe into Arm following its launch of its own AGI CPU — regulators investigate if chip designer is restricting architecture access to rivals
The company's expansion from design to manufacturing has got some of its customers worried.
Arm Holdings, the maker of the popular Arm architecture used by Qualcomm, Apple, and several other companies, is facing an antitrust investigation as the U.S. Federal Trade Commission (FTC) looks into the company’s operation. Bloomberg reports that the FTC is determining if the company is trying to monopolize the Arm architecture and either only give customers lower quality designs for their own semiconductors or outright deny them access to its licenses. The move comes as Arm launched its own AGI CPU focused on data centers in March 2026, a significant departure from the company, whose business previously focused on licensing its chip designs to other companies.
The company’s legal troubles began when it sued Qualcomm, the biggest manufacturer of smartphone chips, for using Nuvia’s ARM licenses after it acquired the startup in 2022. Arm Holdings argued that the smartphone chipmaker cannot use Nuvia’s licenses after its acquisition, and that it should have acquired a new one to continue using the startup’s designs based on Arm licenses. Arm ultimately lost the case, allowing Qualcomm to continue using the Oryon cores it acquired from Nuvia.
The Qualcomm lawsuit broke the longstanding relationship the two companies had, and it also opened a can of worms for Arm. The former launched a global antitrust campaign against the latter because of the case, saying that it was using its dominant market position to prevent competition. It reached out to the European Commission, the U.S. FTC, and Korea’s Fair Trade Commission to present its case, with the Korean government agency raiding Arm’s Seoul office in November 2025.
While the x86 processor still has the advantage when it comes to desktops and laptops, its advantage is slowly being eroded by Arm-based Apple Silicon and Qualcomm’s Snapdragon X-series chips. On the other hand, it has cornered the mobile market, with Apple, Qualcomm, Samsung, MediaTek, and other mobile device chipmakers using Arm architecture. Some analysts also say that it will eventually dominate the AI server industry, with over 90% of custom processors expected to use an Arm chip by 2029.
Arm’s launch of its own AGI processor has got its customers (and now potential competitors as well) wary of its status as both chip designer and manufacturer. Arm did not introduce a processor for consumer computing, meaning it hasn’t directly challenged some of its biggest customers. However, the fact that it has expanded into building physical chips has worried them that it could leverage the popularity of the Arm architecture to gain an unfair advantage and limit competition.

Rando99 ARM got foolish and greedy, biting the fattest fingers and hands that feed it. Had they simply tried to invade a new chip niche from the start they could have easily slid in and subsumed that one without any pushback.Reply -

Yes and no. If you look at cloud companies that make their own CPUs: Google, Amazon, Microsoft... I'm not sure how many of these guys really want to be in the silicon business. It's just that, before now, ARM only sold IP. So, to get an ARM-based CPU, someone had to take that IP and assemble it together, then get it manufactured and do all the system-level integration and bring-up work. By ARM centralizing that stuff, they can save their customers some time, headaches, and potentially some money.Rando99 said:ARM got foolish and greedy, biting the fattest fingers and hands that feed it.
The only two companies who were reselling ARM IP in server CPUs you could buy on the open market were Ampere Computing (which ARM bought) and Nvidia, who pivoted away from using purely ARM IP and are now using their own cores in Vera. Nvidia's CPUs are also more specialized and not primarily aimed at general cloud-computing workloads.
There's no remaining niche big enough. They're already getting pushed out of the microcontroller & small embedded segment by RISC-V. Competing on AI chips is a very tough battle. So, tell me what niches are out there, with meaningful scale, for them still to exploit?Rando99 said:Had they simply tried to invade a new chip niche from the start they could have easily slid in and subsumed that one without any pushback.
To understand why they did what they did, you have to look at the numbers. If you compare ARM's revenues to that of actual chip companies, ARM is tiny! They tried forcing their customers into more aggressive licensing agreements, but that blew up spectacularly, with the Qualcomm litigation. So, getting into the chip business was pretty much their only remaining option.
Two other big factors at play:
The costs of chip development are rapidly increasing with transistor count and complexity
RISC-V is a looming threat.
On the second point, being a chip-maker means that ARM can pivot towards making RISC-V chips, just like anyone else. Their fate no longer remains tied to the dominance of their own ISA, in any particular market. -
upsetkiller Ah yes the classic American *fairness* launch probes into foreign companies, when they (rightfully so) develop something they dont want to shareReply -

The issue is that ARM is competing with some of its customers. In this case, the most direct competition is probably with Nvidia's Grace and Vera CPUs.upsetkiller said:Ah yes the classic American *fairness* launch probes into foreign companies, when they (rightfully so) develop something they dont want to share
Ever since ARM announced it was getting into the chip business, concerns were raised about a conflict of interest. So, this move really isn't either surprising or inconsistent, for the FTC. -
garbilkee "eroded by Arm-based Apple Silicon and Qualcomm’s Snapdragon X-series chips". ???Reply
This Apple 'erosion' took place when Apple switched to ARM, but since Apple sells the same number laptop/desktops as it did before, this number isn't increasing each year, so this 'erosion' doesn't exist in any meaningful metrics. And as far as Snapdragon laptops are, they barely moved the needle, and are now stuck in first gear, maybe even neutral. So again, no 'erosion' here either. -

Why do you assume they had the same sales volume, year-on-year? According to this, their laptops markedly increased in popularity, after they switched to their own ARM-based CPUs:garbilkee said:"eroded by Arm-based Apple Silicon and Qualcomm’s Snapdragon X-series chips". ???

The initial ramp from 2020 to 2022 is the transition period, where they phased out their x86 models. Pay attention to the part after that, where there's a discontinuous jump and then another bump in 2025.
That's mostly a Windows-on-ARM problem. Once the Nvidia/MediaTek chips start shipping, I expect Windows/ARM popularity to start getting some real traction. This is what Qualcomm always needed - some competition, to help build that market.garbilkee said:And as far as Snapdragon laptops are, they barely moved the needle, and are now stuck in first gear, maybe even neutral.
