SoftBank said to explore potential takeover of US chipmaker Marvell

SoftBank Group considered acquiring US chipmaker Marvell Technology earlier this year, according to sources familiar with the matter.

The Japanese conglomerate, led by Masayoshi Son, reportedly explored combining Marvell with Arm Holdings, the UK chip designer it controls, but discussions did not result in an agreement, though sources say interest could be revived.

Marvell, led by CEO Matthew Murphy, designs semiconductor chips for data centers and reported record revenue of US$2 billion for the quarter that ended August 2, according to the company.

Marvell is valued at about US$80 billion after a 16% stock drop this year, while Arm’s market value is around US$170 billion.

Sources said Marvell may attract interest from other buyers, but there are significant regulatory and management hurdles for any potential deal, including US government scrutiny and antitrust concerns.

SoftBank recently agreed to buy semiconductor designer Ampere Computing and, in January, announced a US$500 billion project called Stargate with OpenAI and Oracle to build US data centers, though the rollout has seen delays.

🧠 Food for thought

Implications, context, and why it matters.

Arm-Marvell raises vertical foreclosure concerns from the Nvidia-Arm case

During NVIDIA’s bid for Arm, the UK’s Competition and Markets Authority (CMA) warned that NVIDIA could curb rivals’ access to Arm tech, then closed its inquiry after NVIDIA ended the deal 1. That vertical foreclosure risk, a supplier limiting rivals’ access to essential technology, would loom over an Arm-Marvell deal.
The CMA sent a Phase 2 probe in the UK on competition and national security grounds 2. Control over semiconductor intellectual property (IP) can harm rivalry, so SoftBank faces hurdles.
Marvell designs data center chips and posted $2 billion in quarterly revenue. It competes with Arm licensees, which matches the vertical integration risk regulators already examined.
Any proposal must make clear that mixing Arm’s licensing with Marvell’s chip design will not disadvantage other Arm customers, since Arm licenses IP to semiconductor chipmakers 1.

Arm data center growth opens migration services work

By 2025, 50% of compute shipped to hyperscalers (the largest cloud providers like Amazon and Google) will be Arm based 3.
Apps such as Paramount+ and Uber moved to Arm based cloud for cost plus energy gains 3. That signals demand from enterprises beyond hyperscalers.
Software vendors and cloud consultancies (systems integrators that help enterprises migrate then optimize workloads in public clouds) can offer Arm optimization plus migration services, since many firms face heavy effort moving legacy apps plus infrastructure 4.
The Arm server market hit $12.39 billion in 2024, with more than 2.6 million units deployed by mid-2025 5.
