In a seismic shift for the artificial intelligence landscape, SoftBank Group Corp. has divested its entire stake in Nvidia Corp., netting approximately $5.83 billion. This move, disclosed in the company’s latest earnings report, underscores a strategic pivot toward deeper investments in AI software and infrastructure, particularly with partners like OpenAI. As Nvidia’s stock continues to dominate headlines amid AI hype, SoftBank’s decision raises questions about the sustainability of the chipmaker’s valuation and the broader AI investment bubble.

According to disclosures, SoftBank sold 32 million shares of Nvidia in October 2025, capitalizing on the chip giant’s meteoric rise. Nvidia briefly became the world’s first $5 trillion company at the end of October, though its value has since retreated. This sale comes as SoftBank founder Masayoshi Son intensifies his focus on AI, including massive bets on OpenAI and projects like Stargate data centers in collaboration with Oracle Corp.

Industry analysts suggest this divestiture is part of a broader unwinding of positions to fund ambitious AI initiatives. Son has been vocal about the undervaluation of AI opportunities, previously stating in 2024 that Nvidia was ‘undervalued’ and planning to stockpile ‘tens of billions’ for AI investments, as reported by posts on X (formerly Twitter).

Strategic Reallocation Amid AI Frenzy

SoftBank’s move has stirred fresh concerns about an AI bubble, especially following warnings from Wall Street executives and short sellers. Reuters noted that the sale jolted stock markets, amplifying fears that the AI investment frenzy may have peaked. Nvidia’s shares slipped in response, falling about 1.3% in premarket trading, per The Globe and Mail.

Meanwhile, SoftBank’s net profit doubled to $16 billion, buoyed by gains from its OpenAI and PayPay holdings, as detailed in the Financial Times. This financial boost positions SoftBank to pour resources into next-generation AI, including a reported $40 billion investment in OpenAI, according to BitcoinEthereumNews.

Posts on X highlight ongoing partnerships, such as Nvidia selecting SoftBank as its first customer for an AI supercomputer using Blackwell chips, announced in late 2024. This collaboration persists despite the stake sale, indicating SoftBank’s shift from hardware ownership to operational alliances in AI infrastructure.

Pivoting from Chips to Intelligence Ecosystems

SoftBank’s history with Nvidia is checkered; it previously exited a large position in 2019, missing out on subsequent gains. This time, the sale aligns with Son’s vision of ‘artificial superintelligence’ requiring hundreds of billions in investment. As Bloomberg reports, the funds will support ventures like robot manufacturing sites in the US and deepened ties with OpenAI.

The divestiture coincides with debates over Big Tech’s AI spending, projected to exceed $1 trillion without guaranteed returns, per Yahoo Finance. SoftBank’s stock has surged over twofold in 2025, reflecting investor confidence in its AI strategy, though critics warn of circular deals fueling bubble concerns, as noted in The Straits Times.

Analysts like those at The Guardian suggest SoftBank is topping up its war chest for the next AI wave, moving beyond chip stocks to ‘core AI enablers.’ X posts from investors echo this sentiment, with discussions on SoftBank’s diversification from hardware to intelligence layers.

Market Reactions and Bubble Warnings

Nvidia’s dominance in AI chips has driven its valuation skyward, but SoftBank’s exit signals potential overvaluation. CNBC highlights SoftBank’s ‘all in’ bet on OpenAI, including talks over the Stargate project. This comes amid Nvidia’s partnerships, like building Japan’s largest AI Factory with SoftBank using DGX B200 systems, as per X updates from 2024.

The sale has not deterred SoftBank’s operational ties; it’s reportedly in discussions for major GPU acquisitions from Nvidia, per earlier reports on X. However, The New York Times notes that the move stokes investor concerns about overdone AI rallies.

SoftBank’s Vision Fund has faced massive losses, but its pivot ties it closer to OpenAI amid circular investment worries. As Investopedia reports, the complete sale of 32 million shares raised nearly $6 billion, funding AI expansion including a $22.5 billion OpenAI commitment, per Rolling Out.

Long-Term Implications for AI Investment

Looking ahead, SoftBank’s strategy emphasizes software and ecosystems over hardware stakes. Son’s pushback against AI bubble narratives—stating ‘the future is much bigger’ in 2024 X posts—underscores optimism. Yet, Tom’s Hardware details the offloading of shares to fund Stargate and other initiatives.

Market sentiment on X reflects mixed views: some see it as savvy diversification, others as a bubble signal. SoftBank’s shares gained nearly 2% post-announcement, per The Globe and Mail, while Nvidia dipped.

This realignment could reshape AI funding, with SoftBank positioning as a kingmaker in superintelligence. As investments in chips give way to intelligence platforms, the industry watches if Son’s bets will yield the transformative returns he envisions.

Evolving Partnerships in AI Hardware

Despite the sale, Nvidia and SoftBank’s ties remain strong. Bloomberg reported in 2024 that Nvidia picked SoftBank for its Blackwell-based supercomputer, a deal valued in the billions. X posts from investors like unusual_whales highlight this as a key development.

SoftBank’s broader portfolio includes Arm Holdings and Taiwan Semiconductor, benefiting from AI growth, as noted in The Globe and Mail. This diversification mitigates risks from single-stock exposure.

Analysts predict SoftBank’s funds will accelerate projects like OpenAI’s expansion, potentially leading to breakthroughs in generative AI and robotics.

Navigating Valuation Risks

The AI sector’s volatility is evident in Nvidia’s fluctuations. Reuters warns of bubble fears amplified by SoftBank’s move, with short sellers eyeing corrections.

SoftBank’s profit surge, per Bloomberg, provides a buffer, but the firm’s history of bold bets—some spectacular failures—adds caution.

Ultimately, this divestiture may signal a maturing AI market, where investors shift from hype to sustainable innovation.
