SoftBank's Brand Bets: From Arm to WeWork

In 2000, Masayoshi Son met Jack Ma for six minutes and wrote a $20 million check for an obscure Chinese e-commerce startup called Alibaba. That single bet returned more than $60 billion over the following two decades. It is the most profitable venture investment ever made, and it is also the clearest lens through which to understand SoftBank Group Corp.

SoftBank is not a consumer goods company. It does not make products you find in supermarkets. What it does is deploy capital, in amounts ranging from tens of millions to tens of billions of dollars, into technology businesses that Masayoshi Son believes will dominate the next phase of the global economy. The brands in its portfolio, including Arm Holdings, Uber, ByteDance (parent of TikTok), and DoorDash, touch hundreds of millions of people daily. WeWork touched them too, until it went bankrupt.

We tracked SoftBank's investment history, portfolio, and current capital strategy so you can see exactly how this company operates and where its bets are concentrated in 2026.

Who Is SoftBank?

SoftBank Group Corp. is a publicly traded Japanese multinational conglomerate headquartered in Minato, Tokyo. The company trades on the Tokyo Stock Exchange under ticker 9984. Masayoshi Son, who founded SoftBank in 1981, is Chairman and CEO and holds a controlling stake.

SoftBank is not a traditional venture capital firm. It is not a private equity fund. At its core, it is a technology investment company that takes large stakes in technology businesses at various stages of development, from growth-stage startups to established public companies.

The company's primary investment vehicles are:

• SoftBank Vision Fund 1 (SVF1): Launched in 2017 with approximately $100 billion in committed capital, the largest private equity and technology fund ever raised at the time. Key investors included Saudi Arabia's Public Investment Fund ($45 billion), Abu Dhabi's Mubadala ($15 billion), and contributions from Apple, Foxconn, and Sharp.
• SoftBank Vision Fund 2 (SVF2): Launched in 2019 with SoftBank as the primary investor, after external investors declined to commit capital following governance concerns and the WeWork fallout.
• SoftBank's direct balance sheet holdings: Including its majority stake in Arm Holdings and residual positions across portfolio companies.

The Arm Holdings Story: SoftBank's Most Valuable Asset

SoftBank acquired Arm Holdings, the British semiconductor intellectual property company, in 2016 for approximately $32 billion. At the time, it was the largest acquisition of a European technology company on record.

Arm does not manufacture chips. It designs the processor architectures and instruction sets that other companies license to build their own semiconductors. The Arm architecture is in virtually every smartphone processor in the world, including Apple's A-series, Qualcomm's Snapdragon, and MediaTek's chips. Arm-based designs are also taking share in data centers as Amazon, Google, and Microsoft build custom server chips based on the architecture.

SoftBank's thesis was straightforward: the spread of connected devices, AI workloads, and autonomous systems would require exponentially more semiconductor processing capacity. Arm, as the foundational design layer licensed by almost every chip maker, would sit at the center of that growth.

SoftBank attempted to sell Arm to Nvidia in 2020 for approximately $40 billion. That deal collapsed in February 2022 after US, UK, and European regulators signaled they would block it on competition grounds. Instead, SoftBank listed Arm on NASDAQ in September 2023 in the largest technology IPO of that year, raising approximately $4.9 billion at a valuation of approximately $60 billion. SoftBank retained approximately 90% of Arm's shares following the IPO.

By early 2026, Arm's market capitalization had grown well beyond that IPO figure as AI-related semiconductor stocks re-rated sharply upward. According to Bloomberg analysis from September 2025, Arm accounts for approximately half of SoftBank's entire portfolio value.

The Vision Fund: Wins and Write-downs

The SoftBank Vision Fund's record is a study in the extremes of concentrated, large-scale technology investment.

Notable wins:

• Alibaba: The original bet, now substantially exited, returned multiples of the $20 million initial investment over two decades.
• DoorDash: SoftBank invested across multiple rounds. DoorDash listed on NYSE in December 2020 at approximately $39 billion and is now the market leader in US food delivery.
• Coupang: The South Korean e-commerce company listed on NYSE in March 2021 and has grown into South Korea's largest e-commerce platform.
• ByteDance: SoftBank holds a minority stake in ByteDance, the parent of TikTok. ByteDance remains private as of early 2026 with an estimated valuation in the $200 to $250 billion range.

Notable failures:

• WeWork: SoftBank invested approximately $10.65 billion in WeWork across multiple rounds, pushing its private valuation to $47 billion at the peak. WeWork's 2019 IPO attempt collapsed when its S-1 filing exposed massive losses, unusual governance structures, and related-party transactions. Co-founder Adam Neumann was removed. SoftBank provided a rescue package that made it WeWork's controlling shareholder. WeWork filed for bankruptcy in November 2023. SoftBank's equity was wiped out.
• Greensill Capital: SoftBank invested approximately $1.5 billion in this supply chain finance company. Greensill collapsed in March 2021, and SoftBank wrote off nearly the entire investment.
• Katerra: A construction technology company that received approximately $2 billion from Vision Fund. Katerra filed for bankruptcy in June 2021.
• Oyo Hotels: The Indian budget hotel aggregator received approximately $1.5 billion from Vision Fund and reached a peak private valuation of $10 billion. Oyo contracted significantly from that peak.

The Vision Fund reported cumulative losses of approximately $50 billion on its portfolio between 2021 and 2023, driven by falling technology valuations across public and private markets. Performance has partially recovered since then as valuations rebounded.

SoftBank's AI Bet: The Next Vision

Since 2025, Masayoshi Son has been explicit about SoftBank's next investment thesis: artificial general intelligence (AGI) and its real-world applications.

Son has described AGI as the most important technological development in human history. Whether or not that assessment is accurate, it is directing hundreds of billions of dollars in capital allocation decisions.

In December 2024, SoftBank announced it would invest $100 billion in the United States over four years, focused on AI infrastructure and technology companies. This was announced alongside Son's meeting with then President-elect Donald Trump at Mar-a-Lago.

In early 2025, SoftBank became a founding partner in Stargate, a joint venture with OpenAI, Oracle, and other technology companies, committing to invest up to $500 billion in US AI infrastructure over four years, covering data centers, semiconductor capacity, and AI development programs. SoftBank's initial committed tranche was announced at $100 billion.

SoftBank also holds a significant stake in OpenAI, accumulated through secondary share purchases. The precise size and cost basis of this position has not been publicly confirmed by SoftBank.

SoftBank's Japan Business: Telecoms and Baseball

Beyond its investment activities, SoftBank Group Corp. owns SoftBank Corp., Japan's third-largest mobile telecommunications operator, serving approximately 30 million subscribers under the SoftBank and Y!mobile brands.

SoftBank Corp. is separately listed on the Tokyo Stock Exchange and generates stable recurring revenue from the telecoms business. It operates in a competitive domestic market alongside NTT Docomo and KDDI.

SoftBank also owns Fukuoka SoftBank Hawks, a professional baseball team in Japan's Pacific League. The team has won multiple Japan Series championships under SoftBank's ownership.

How SoftBank Differs from Traditional Technology Investors

Traditional venture capital firms spread investment across dozens or hundreds of companies in relatively small amounts, accepting that most bets will fail while a small number generate fund-defining returns. SoftBank's Vision Fund invested in far fewer companies but in much larger amounts, attempting to identify definitive category winners and fund them to market dominance.

The logic traces back to Alibaba. Son's view is that the initial investment worked because SoftBank gave the company enough capital to win its category outright. In markets with strong network effects, the winner typically captures most of the value. Therefore, Son argues, backing a probable winner with overwhelming capital is better than spreading bets thinly.

Critics say this approach distorted markets by allowing companies like WeWork to sustain massive losses for years on SoftBank's capital, creating artificial competitive pressure on rivals who lacked that subsidy. Proponents say it is the rational strategy for investors who believe technology categories will be winner-take-most. Both arguments are supported by the Vision Fund's actual record.
