In its quarterly results, the Japanese tech investor said it had sold all the 32.1 million Nvidia shares it held in October to bankroll CEO Masayoshi Son’s sweeping AI push, built around his “all in” bet on ChatGPT-creator OpenAI

The SoftBank Nvidia stake sale, worth $5.8 billion, has renewed global concerns about a potential AI bubble. Investors see this move as a warning that the recent artificial intelligence boom may be cooling. SoftBank sold all 32.1 million of its Nvidia shares in October to fund CEO Masayoshi Son’s expanding AI vision centered around OpenAI and the colossal “Stargate” data-center initiative.
Market Reaction and Investor Concerns
The SoftBank Nvidia stake sale rattled stock markets on Tuesday, sparking doubts that AI valuations might have climbed too high. Nvidia shares fell more than 2% in early U.S. trading, dragging down the S&P 500 index. Meanwhile, AI-focused firm CoreWeave trimmed its revenue forecast due to a contract delay, pushing its stock down 9%. These developments intensified worries that an AI market correction could be near.
Masayoshi Son’s AI Funding Strategy
Analysts said Masayoshi Son’s decision to sell Nvidia shares is part of a long-term strategy to redirect funds toward next-generation AI infrastructure. SoftBank also liquidated about $9.2 billion of its T-Mobile stake, adding to its growing “AI war chest.” The proceeds will support projects such as the $500 billion Stargate data-center expansion and up to $40 billion in potential OpenAI funding.
SoftBank’s Nvidia Exit Timing and Missed Gains
The timing of the SoftBank Nvidia stake sale has drawn mixed reactions. Some experts point out that SoftBank previously missed over $100 billion in potential Nvidia gains after selling its stake in 2019—before the AI surge. Others believe this move simply reallocates capital to new opportunities within the AI ecosystem.
OpenAI Partnership and the Aftermath of the SoftBank Nvidia Stake Sale
By exiting Nvidia, SoftBank deepens its financial and strategic commitment to OpenAI. The startup, rumored to be eyeing a $1 trillion IPO next year, could reward early investors such as Microsoft and SoftBank handsomely. However, analysts caution that OpenAI’s massive $1.4 trillion infrastructure ambitions still lack transparent funding plans.
Analysts’ Outlook on the SoftBank Nvidia Stake Sale
Michael Ashley Schulman of Running Point Capital Advisors commented, “By cashing out, SoftBank secures liquidity to double down on AI investments. Yet, the move also highlights Masayoshi Son’s willingness to play high-stakes poker with global tech valuations.”
Future Outlook: What the SoftBank Nvidia Stake Sale Means for AI Investors
Looking ahead, market experts say the SoftBank Nvidia stake sale could trigger broader discussions about sustainability in AI valuations. If AI stocks continue their correction trend, investors may favor companies building real infrastructure—such as SoftBank’s Stargate project—over speculative AI ventures..
