SoftBank pauses $50 billion Switch acquisition, throwing Stargate AI infrastructure plans into limbo

SoftBank Halts Ambitious Data Center Acquisition

SoftBank has paused acquisition talks with U.S. data center operator Switch, stepping back from what would have been a $50 billion deal and one of the Japanese conglomerate's largest transactions to date1

. For months, Masayoshi Son pursued direct control of Switch's network of energy-efficient data centers, convinced it would be essential to rolling out the ambitious $500 billion Stargate AI infrastructure project2

. Earlier this month, Son conceded that a full acquisition was off the table and scrapped a planned January announcement, though the two sides remain in active discussions about a partial investment or partnership2

Stargate Project Faces Infrastructure Uncertainty

The paused acquisition talks throw the Stargate AI infrastructure project into uncertainty at a critical moment. OpenAI's Stargate initiative, funded by OpenAI, SoftBank, Oracle, and Abu Dhabi-backed MGX, aims to build up to 10 gigawatts of AI capacity by 2029, with sites planned across Texas, New Mexico, Wisconsin, and Michigan1

. Control of physical infrastructure—not just chips or models—was meant to be a defining feature of the project. Switch, with its large-scale, energy-efficient campuses designed to support high per-cabinet power draw and dense AI racks, would have played a major role in achieving these goals under SoftBank's control1

1

. Bloomberg Intelligence analysts Kirk Boodry and Chris Muckenstrum noted that ending talks on a full acquisition leaves SoftBank's data center plans "in limbo, as Stargate announcements remain few and far between"1

1

. Without direct ownership, the Stargate project becomes more dependent on third-party operators, limiting SoftBank's ability to control critical factors like power allocation and computing power deployment.

Financial and Regulatory Roadblocks Mount

Several factors contributed to the collapse of the deal to acquire data center operator Switch. The sheer scale of the transaction presented significant challenges, with some within SoftBank reportedly "wary" about both the $50 billion price tag and the operational complexity of managing dispersed data center campuses from Las Vegas to Atlanta2

2

. Regulatory scrutiny posed another substantial hurdle. Any takeover of a major U.S. data center operator by a foreign entity would attract serious attention from the Committee on Foreign Investment in the U.S., particularly given the strategic importance of AI infrastructure1

. Even if the deal passed review, the process could have delayed or significantly reshaped the transaction. Meanwhile, Switch is preparing for an IPO as soon as this year, with backers discussing valuations of roughly $60 billion including debt2

Balance Sheet Pressure Intensifies

SoftBank's aggressive AI spending spree has placed mounting pressure on its creditworthiness and financial stability. Over the past year, the company has amassed an 11% stake in OpenAI by injecting $22.5 billion just last month, bought Ampere Computing for $6.5 billion, and announced a $5.4 billion acquisition of ABB's robotics unit2

. To finance these investments, SoftBank sold its entire Nvidia stake, exited its T-Mobile US position, and expanded margin loans backed by its shares in Arm Holdings1

. Earlier this month, S&P Global warned that this combination of aggressive AI spending and a sharp decline in Arm's share price was increasing pressure on SoftBank's credit profile, noting that "if it does not take prompt easing measures, such as liquidation of held assets, pressure will intensify on the credit ratings"2

Alternative Pathways Through DigitalBridge

In late December, SoftBank completed a $4 billion deal to buy DigitalBridge, a New York-based investment firm that holds a majority stake in Switch1

. This acquisition gives SoftBank indirect access to data center assets without taking on full operational responsibility, allowing the company to co-invest and align infrastructure development with the needs of its AI portfolio companies. This more asset-lite approach mirrors structures SoftBank has used before, including its Ohio manufacturing facility operated by Foxconn under a partnership model1

1

. While a minority investment or partnership would provide some exposure to the sector, it falls short of the overall control SoftBank has sought in other areas such as semiconductors and robotics. The question now is whether this indirect pathway will prove sufficient to support the massive computing power requirements of the Stargate project, or whether Son will find another route to secure the infrastructure control he has long pursued. Despite missing out on the AI hardware rush that enriched companies like Nvidia and Taiwan Semiconductor Manufacturing Co., Son has shown persistence in pursuing strategic assets—he famously eyed Arm Holdings for years before acquiring the UK chip designer in 20162
