SoftBank’s latest takeover approach sent shockwaves across the semiconductor industry. The Japanese conglomerate, led by visionary billionaire Masayoshi Son, aimed to buy US-based Marvell Technology in a potential $100 billion deal that would have broken all records for sector mergers.
This ambitious move sought to create an AI-centric hardware giant by merging Marvell, renowned for its data infrastructure chips, with Arm Holdings, the key UK chip designer, both under SoftBank’s control.
Though talks eventually collapsed, the bid reveals Son’s expansive investment strategy targeting the rise of artificial intelligence.
How Did SoftBank’s Marvell Bid Emerge?
Masayoshi Son has eyed Marvell Technology for years, analyzing its position in next-generation semiconductor hardware suitable for artificial intelligence acceleration.
SoftBank ramped up acquisition overtures to Marvell in early 2025, engaging in informal negotiations with the company’s executives.
The logic for the bid was clear: SoftBank already owns Arm Holdings and is aggressively expanding its role in AI infrastructure by buying designers and manufacturers.
Combining Marvell’s massive datacenter and connectivity portfolio with Arm’s renowned chip IP could create unmatched market synergies and accelerate innovation in data-driven AI processing.
Did you know?
SoftBank also owns Arm Holdings, the UK chip design company whose tech powers 95% of the world’s smartphones.
Despite close ties between Son and US leaders, including President Donald Trump, the Marvell takeover faced enormous regulatory skepticism.
Authorities remained wary due to the sheer scale and strategic importance of US semiconductor makers, especially amid increasing geopolitical sensitivities.
A previous $40 billion Nvidia-Arm deal was blocked by the Federal Trade Commission in 2022, citing concerns that it would restrict rivals' access to essential chip technology.
The prospect of SoftBank controlling both Arm and Marvell drew similar competition alarms, specifically over market dominance and the future of open chip innovation.
How Did the Market React to the Bid?
News of SoftBank’s interest in Marvell led to an immediate 11 percent surge in Marvell’s stock, briefly boosting its market value close to $80 billion.
This was an outlier compared to rival companies like Nvidia, Broadcom, and Arm, whose 2025 stock performance far outpaced Marvell’s 16 percent year-to-date decline.
Investors and industry analysts weighed the possible breakthrough and increased risk brought on by the merger.
The failed negotiation underscores the market’s hunger for scale, but also rising awareness of regulatory chokepoints curbing industry consolidation.

What Does This Mean for AI Chip Competition?
The Marvell bid is part of SoftBank’s larger campaign to dominate AI infrastructure. Aside from Marvell and Arm, SoftBank recently acquired Ampere Computing and invested billions in Intel, while gradually increasing its stake in Nvidia.
These moves aim to control entire platforms powering AI breakthroughs across the cloud, data centers, and devices.
With regulatory skepticism at its highest, the deal’s collapse illustrates how mega-deal ambitions face a stricter landscape.
Nonetheless, mashups like the proposed Marvell-Arm combination are likely to remain attractive as AI deployment intensifies industry rivalry.
Could SoftBank Revive Marvell Acquisition Talks?
SoftBank and Marvell are not actively negotiating, with insiders saying the early 2025 bid ended without agreement on terms. Yet, given Son’s habit of monitoring deal targets for years, renewed interest cannot be ruled out, especially if market conditions change and regulatory sentiment softens.
SoftBank is known for surveying dozens of potential chip acquisitions each year, even if most never proceed, indicating that large-scale moves remain a pillar of its investment philosophy.
SoftBank’s approach to Marvell highlights a relentless quest for AI leadership, defying barriers posed by markets and regulators.
Industry watchers expect more bold bids from major players as AI continues to reshape the future of semiconductors and tech infrastructure.
