The Vision Fund: Softbank’s American Power Play
Softbank launched its first Vision Fund in 2017 with nearly $100 billion in capital. The goal: identify and back the next generation of tech giants. The US market became the primary focus, attracting the largest share of Vision Fund dollars. CEO Masayoshi Son’s strategy was simple — go big or go home.
Key characteristics of the Vision Fund’s US approach:
- Bet on market leaders with global ambitions
- Inject massive capital to accelerate growth, often at the expense of profitability
- Take large equity stakes, sometimes with board seats
- Push portfolio companies toward aggressive expansion
The results have been a mixed bag. Some investments, like DoorDash and Uber, went public and delivered strong returns. Others, most famously WeWork, turned into cautionary tales of overvaluation and poor governance.
Softbank’s Biggest US Investments: A Breakdown
1. Uber Technologies (Ride-Hailing & Mobility)
Softbank first invested in Uber in 2018, acquiring a 15% stake for about $8 billion. At the time, Uber was locked in a global battle with Didi Chuxing and Lyft. Softbank’s money and influence helped Uber go public in 2019.
| Investment Aspect | Details |
|---|---|
| Initial Investment | ~$8 billion for 15% stake (2018) |
| Current Status | Public company (NYSE: UBER) |
| Estimated Return | Mixed — stock fluctuated, but Softbank has partially cashed out profitably |
| Key Lesson | Softbank’s backing gave Uber runway to dominate — but profitability took years |
Uber remains one of Softbank’s most visible US holdings. The company has since expanded into food delivery (Uber Eats), freight, and autonomous vehicles. For Softbank, it’s a play on the future of transportation and logistics.
2. WeWork (Co-Working & Real Estate)
This is the investment everyone remembers. Softbank poured over $16 billion into WeWork, making it the company’s biggest single bet. The 2019 IPO collapse exposed massive governance problems and inflated valuation.
Why Softbank doubled down despite red flags:
- Believed WeWork was a tech company disrupting real estate
- Saw potential for a global community platform
- Misjudged the founder’s leadership and financial controls
After a painful restructuring and a pandemic that decimated office demand, WeWork filed for bankruptcy in 2023. Softbank wrote off nearly the entire investment. It’s a stark reminder that even the smartest money can make catastrophic mistakes.
3. DoorDash (Food Delivery)
When Softbank led a $535 million investment in DoorDash in 2019, delivery wasn’t yet a necessity. The pandemic turned it into one. DoorDash went public in 2020, and Softbank’s stake soared.
Why DoorDash succeeded where other Softbank bets faltered:
- Strong unit economics and focus on suburban markets
- Timely IPO during a delivery boom
- Efficient expansion into adjacent services (convenience, grocery)
Softbank reported billions in gains from its DoorDash position. The investment validated the firm’s thesis: back the dominant player in a growing category, even if it’s losing money early on.
4. Arm Holdings (Semiconductor Design)
Though Arm is headquartered in the UK, its US listing and deep ties to American chip makers make it a crucial part of Softbank’s US portfolio. Softbank acquired Arm in 2016 for $32 billion, then took it public on Nasdaq in 2023.
Arm’s chip designs power nearly every smartphone in the world. The IPO was a major win for Softbank, raising $4.9 billion and valuing the company at over $50 billion. As AI demand skyrockets, Arm’s energy-efficient architecture becomes even more critical.
5. Slack Technologies (Enterprise Communication)
Softbank invested $3.5 billion in Slack through its Vision Fund in 2017. At the time, Slack was the hot new workplace tool challenging email. The investment paid off when Salesforce acquired Slack in 2021 for $27.7 billion.
Key takeaway: Softbank’s bet on enterprise collaboration was ahead of the curve. The remote work trend accelerated Slack’s value, making this one of the fund’s most successful exits.
6. Other Notable US Investments
- Nvidia – Softbank bought a $4 billion stake in 2017 and sold it years later, missing out on massive AI-driven gains.
- WeWork competitor Knotel – Another co-working bet that failed.
- OneWeb – Satellite internet startup that Softbank backed heavily; filed for bankruptcy before being rescued by the UK government.
- Roivant Sciences – Biotech holding company; Softbank invested $1.1 billion.
The Impact of Softbank’s US Portfolio on Startup Funding
Softbank’s presence fundamentally changed how startups raise money. By writing $100 million+ checks, it forced other venture firms to either follow suit or get left behind. The Impact of Softbank's Us Portfolio on Startup Funding is still being felt today.
Three major changes Softbank introduced:
- “Blitzscaling” became the norm – Softbank encouraged founders to spend aggressively on growth, regardless of profitability.
- Valuations inflated across the board – Competitors had to match Softbank’s terms or risk losing the best deals.
- More exits via direct listings or SPACs – Softbank pushed portfolio companies to go public faster.
Critics argue this approach created a bubble. Supporters say it accelerated innovation. Either way, Softbank reshaped the US venture landscape permanently.
How Softbank’s Investment Strategy Is Shaping the US Tech Landscape
Softbank’s strategy is not just about picking winners. It’s about creating entire ecosystems. By investing in companies like Uber, DoorDash, and Arm, Softbank builds synergies between its portfolio firms. For example, DoorDash uses Uber-style logistics; Arm chips power the devices that run these apps.
