Arm Holdings faces global antitrust scrutiny over chip licensing

Arm Holdings faces global antitrust scrutiny over chip licensing

Rule Changes

US, EU, and South Korean regulators are probing whether the company that designs most of the world's smartphone chips is choking off rivals

May 20th, 2026: Eight Wall Street firms raise Arm price targets as stock hits 104% year-to-date gain

Overview

Arm Holdings designs the chip architecture found in roughly 99% of smartphones and a growing share of data-center processors. On May 6 it reported record quarterly results. Five days later, Bloomberg revealed the Federal Trade Commission had opened an antitrust probe into how the company distributes those designs.

Arm shares dropped 8.46% when the FTC probe news broke on May 15, then recovered as investors focused on the company's record earnings. The stock was up about 104% year-to-date by May 20. South Korea raided Arm's Seoul office in November 2025; Brussels is reviewing a parallel complaint from Qualcomm.

Why it matters

Arm's licensing model sits underneath most phones and data-center processors. A forced change to its terms ripples through every device you own.

  1. Eight Wall Street firms raise Arm price targets as stock hits 104% year-to-date gain

    Latest Market

    RBC, Jefferies, TD Cowen, Guggenheim, Raymond James, Needham, Rosenblatt, and KeyBanc all raised price targets following Arm's earnings beat. The stock reached roughly $257, up about 104% year-to-date.

  2. News spreads globally; Arm shares slip less than 1%

    Market

    Reports cite the preserved-documents order and a Qualcomm-style monopolization theory. Stock closes near $208 after nearly doubling year-to-date.

  3. FTC probe of Arm becomes public

    Investigation

    Bloomberg reports the agency has ordered Arm to preserve documents and is examining whether the company is monopolizing the chip market.

  4. Arm reports record Q4 FY2026 results

    Financial

    Total revenue hit $1.49 billion, up 20% year over year. Licensing revenue reached a record $819 million, up 29%. Data center royalty revenue more than doubled.

  5. Arm unveils its own data-center chip with Meta

    Product

  6. South Korean regulators raid Arm's Seoul office

    Investigation

    KFTC officials seize documents as part of a probe sparked by Qualcomm's complaint over licensing access.

    Acquisition

    Masayoshi Son takes the British chip designer private, beginning the push to monetize the licensing model more aggressively.

Historical Context

3 moments from history that rhyme with this story — and how they unfolded.

January 2017 - August 2020

FTC v. Qualcomm (2017-2020)

The FTC sued Qualcomm under chair Edith Ramirez, accusing the chipmaker of monopolizing modem markets through its 'no license, no chips' policy and refusing to license rivals. Judge Lucy Koh ruled for the FTC in 2019 and ordered Qualcomm to renegotiate its licenses globally.

Then

Qualcomm appealed and the 9th Circuit unanimously reversed in 2020, finding that hyper-competitive conduct is not the same as anticompetitive conduct.

Now

The ruling raised the bar for FTC chip-licensing cases. It left unclear when a dominant IP holder's licensing decisions cross into illegal monopolization.

Why this matters now

The FTC must navigate the same legal terrain in the Arm case. Its theory of harm will likely mirror the Qualcomm playbook, but it has to avoid the 9th Circuit reasoning that doomed the earlier case.

May 1998 - November 2001

United States v. Microsoft (1998-2001)

The Justice Department sued Microsoft for using its Windows monopoly to crush Netscape and other browser rivals. Judge Thomas Penfield Jackson ordered Microsoft broken up; an appeals court reversed but upheld the underlying liability finding.

Then

Microsoft settled in 2001 with a consent decree that required it to share interoperability information and let computer makers configure Windows more freely.

Now

The case became the model for tech antitrust. A dominant platform that tilts the playing field against its own customers faces real enforcement risk.

Why this matters now

Arm's situation parallels Microsoft's. A dominant platform that millions of products depend on starts competing with the developers that license its technology. The same legal theory applies: using a foundational position to advantage a downstream business.

May 2009

European Commission v. Intel (2009)

Brussels fined Intel €1.06 billion for paying computer makers like Dell and HP to use Intel chips over AMD's, finding the rebates excluded a competitor from the x86 CPU market.

Then

Intel appealed and the case bounced through EU courts for over a decade. Parts of the fine were eventually overturned.

Now

The case established that a chip monopolist's commercial terms, even when nominally voluntary, can be illegal if they foreclose competition. EU regulators kept the theory active across later tech cases.

Why this matters now

If Brussels takes up Arm based on Qualcomm's complaint, the Intel precedent is the closest playbook. Both turn on whether a dominant chip firm's licensing or pricing decisions effectively shut competitors out of customer relationships.
