Marvell Technology Soars After Report SoftBank Explored Takeover, Eyeing ARM Tie‑Up

Marvell Technology (NASDAQ: MRVL) jumped on Thursday after Bloomberg reported that SoftBank Group explored a takeover of the U.S. chipmaker earlier this year—an approach that, if completed, would have marked the largest deal in semiconductor history. While no agreement was reached and talks aren’t active, people familiar with the matter said interest could be revived. ^[1]

SoftBank explored a Marvell takeover earlier in 2025, studying the company “on and off for years,” according to Bloomberg reporting. The two sides failed to agree on terms. ^[2]
The strategic idea under discussion included combining Marvell with ARM, the U.K. chip designer SoftBank controls—tying Marvell’s data‑center and networking silicon to ARM’s CPU ecosystem amid the AI boom. ^[3]
Scale: Such a transaction would have been the semiconductor industry’s largest‑ever deal, highlighting the intense race to build end‑to‑end AI platforms. ^[4]
Current status: No active negotiations now, though interest could resurface, sources told Bloomberg. ^[5]

Why SoftBank might want Marvell

SoftBank founder Masayoshi Son has been vocal about betting big on AI hardware. Marvell’s expertise in custom accelerators, high‑speed networking, and cloud/datacenter silicon could complement ARM’s CPU IP—potentially creating a portfolio spanning compute and connectivity for hyperscalers building AI infrastructure. That logic aligns with the Bloomberg account that Son has studied Marvell repeatedly as a beneficiary of the AI build‑out. ^[6]

How the market reacted

Premarket: MRVL spiked nearly 10% to about $102 after the Bloomberg report circulated, before paring gains. ^[7]
Intraday (12:48 UTC): Shares were still up about 6% near $92.90 (chart above).
Coverage from Seeking Alpha echoed the move and the source report, noting the takeover exploration and the lack of current talks. ^[8]

What would stand in the way of a deal

Regulatory scrutiny would be intense. Any cross‑border acquisition of a major U.S. chip supplier would likely face CFIUS review and antitrust questions in multiple jurisdictions. The sheer size—signaled by Bloomberg and partner outlets as record‑setting for semis—would add further complexity to financing and approvals. (Context on “largest‑ever” characterization: Bloomberg’s reporting via The Japan Times.) ^[9]

Timeline

2:38 a.m. UTC (Nov. 6): Bloomberg publishes its first report that SoftBank explored a Marvell takeover.
9:10 a.m. UTC (Nov. 6): Bloomberg updates the story. ^[10]

What to watch next

Any renewed outreach by SoftBank or fresh board‑level signals from Marvell. (The reporting says interest could be revived, even though talks are not active now.) ^[11]
Follow‑on market moves in related names—particularly ARM—as investors handicap the likelihood of a combination and the broader AI‑chip consolidation theme. MarketWatch’s early read-through already tied the report to enthusiasm around ARM and AI infrastructure. ^[12]
Official statements: Neither side has confirmed the exploratory talks in today’s coverage; watch company communications and regulatory filings for any change in posture. ^[13]
