Inside SoftBank's $100B Second Act

Masa Son lost $16B in a single quarter and came back swinging.

The Main Story: Masayoshi Son's Comeback Is the Most Audacious in Tech Finance

In 2019, Masayoshi Son was the most powerful venture capitalist on Earth. The Vision Fund had deployed $100 billion across a portfolio that included Uber, WeWork, Arm, ByteDance, and dozens of other bets. By 2022, he was writing down billions, WeWork had imploded, and the financial press was writing eulogies for his career.

They wrote too soon. Son's second act began quietly with the Arm IPO in September 2023 — a listing that valued the chip design company at over $65 billion and gave SoftBank an unrealised gain that erased years of Vision Fund losses in a single stroke. Then came the AI pivot. Son declared that SoftBank would become the world's leading investor in artificial intelligence infrastructure, and he began deploying capital at a pace that made even the first Vision Fund look cautious.

The numbers are staggering. SoftBank has committed over $100 billion to AI investments through 2030, including a massive joint venture with Oracle and OpenAI to build AI data centres across the United States. The company invested directly in several frontier AI startups, took increased positions in NVIDIA through derivatives, and began building its own AI chip design capability through Arm.

Son's thesis is characteristically bold: AI will generate more economic value than any technology in human history, and the companies that control AI infrastructure will be the most valuable enterprises ever created. He may be right. He may be catastrophically wrong again. But nobody can accuse him of thinking small.

Quick Take: The VC Winter Is Thawing (Selectively)

Global venture capital funding in Q1 2026 hit $95 billion — the highest quarterly figure since Q4 2021. But the recovery is dramatically uneven. AI companies captured roughly 45% of all venture dollars, up from 20% two years ago. Everything else — SaaS, fintech, health tech, consumer — remains well below peak levels. This isn't a broad market recovery. It's a rotation into a single thesis, which creates both opportunity and concentration risk.

The Stat That Matters

$16.7 billion — SoftBank's net loss in Q3 2023, the quarter that marked the low point of Son's career. Eighteen months later, the company's market capitalisation had more than tripled. In investing, as in life, the timeline between disaster and redemption is often shorter than anyone expects.

What We're Watching

The secondary market for AI startup equity. As companies like Anthropic, xAI, and Databricks delay their IPOs, secondary platforms like Forge, EquityZen, and Hiive are seeing record trading volumes. The implied valuations on these secondary markets are starting to diverge significantly from primary round pricing, creating arbitrage opportunities and — potentially — the kind of pricing disconnects that precede corrections. Proceed with caution.
