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. Bloomberg
- 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. Bloomberg
- 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. The Japan Times
- 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. The Japan Times
- Current status: No active negotiations now, though interest could resurface, sources told Bloomberg. The Japan Times
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. Bloomberg
How the market reacted
- Premarket: MRVL spiked nearly 10% to about $102 after the Bloomberg report circulated, before paring gains. TradingView
- 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. Seeking Alpha
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.
