SoftBank Shares Plunge as AI Safety Concerns Spur Selloff
SoftBank invests a lot of money in artificial intelligence companies.
Its shares dropped sharply after leaders at OpenAI and Anthropic said advanced AI should be developed more carefully.
They are worried that powerful AI systems could create safety problems.
Investors became concerned that slower development might reduce future profits.
SoftBank is especially exposed because it plans to invest billions in OpenAI and other AI projects.
The company is also borrowing money to help pay for these investments.
OpenAI says it will not seek a public listing in 2026.
Anthropic is considering an IPO as early as next month.
These developments made investors question how quickly AI investments will generate returns.
SoftBank shares fell more than 14% in Tokyo on Monday, their sharpest one-day decline since late June.
Investors reacted after Anthropic and OpenAI executives urged a more cautious approach to advanced AI development.
SoftBank’s expected investment in OpenAI could approach $65 billion by October, increasing its exposure to AI-related risks.
The company is raising debt, including a ¥1 trillion retail bond sale and a $10 billion loan tied to its OpenAI stake.
SoftBank shares are down about 30% from their June peak amid concerns over AI returns, competition, security incidents and a possible delay to OpenAI’s IPO.
