NextFin News - On December 1, 2025, Masayoshi Son, founder and CEO of SoftBank Group Corp, addressed the controversial sale of SoftBank’s entire Nvidia stake, valued at $5.8 billion, during a business forum in Tokyo. Son revealed he was emotionally distressed by the decision, describing it as "crying to sell Nvidia shares," but framed the sale as a strategic move driven by the company's pressing need to finance its massive AI initiatives, particularly investments in OpenAI and the construction of AI data centers. Challenging the notion of an AI bubble, Son derogated critics as those “not smart enough” to appreciate the long-term potential of AI, arguing that if AI achieves even 10% of the global economic output, the enormous current spending would be justified. His remarks coincided with notable presence from Japanese government officials, marking a growing collaboration between Japan and Saudi Arabia, the latter being a major SoftBank investor through its Public Investment Fund (PIF).
Son's disclosure arrived following SoftBank’s recent second-quarter earnings, which showed a doubling of profits to approximately $16.6 billion, buoyed primarily by valuation gains related to OpenAI. The Nvidia share sale was not a sign of waning confidence in Nvidia itself; rather, SoftBank CFO Yoshimitsu Goto emphasized that the divestment was a routine cash management decision necessary to fund the expected $34.7 billion investment into OpenAI by year-end. SoftBank's AI pivot also includes developing the Stargate data center with Hon Hai Precision Industry and acquiring chip designer Ampere Computing. The urgency is reflected in SoftBank's financing methods, ranging from asset sales—including other major holdings like T-Mobile—to issuing bonds and expanding margin loans secured by Arm Holdings shares.
Despite the immediate financial sacrifice of exiting a position in Nvidia—whose original shares, had they been held since 2019, would be worth over $150 billion—Son’s outlook remains bullish on AI’s trajectory. AI's rapid valuation growth is evident in OpenAI’s private valuation escalating from $157 billion in October 2024 to $500 billion following recent employee share sales, eclipsing SpaceX as the world's highest-valued private company.
From a strategic perspective, SoftBank’s divestiture and reinvestment reflect a tilt towards shaping the future AI ecosystem rather than focusing on chip manufacturing leadership through Nvidia. Son’s statements and SoftBank’s capital reallocations indicate a conviction that AI infrastructure and software platforms like OpenAI will yield outsized economic returns over the next decades, consistent with endogenous growth theory frameworks where technological innovation drives sustained productivity and GDP gains.
Nonetheless, this aggressive capital reallocation entails risks, including execution challenges around massive data center projects and the complex restructuring OpenAI must undertake to proceed toward an eventual public offering—a condition tied to further SoftBank funding. The reliance on external investor participation to reach the $40 billion OpenAI funding round and the significant exposure through leveraging debt instruments also expose SoftBank to market volatility and interest rate risks amid a global economic environment influenced by US President Donald Trump's administration’s policies.
Looking forward, SoftBank’s strategy embodies a trend among major investment firms to embrace AI not merely as a sector but as a foundational economic transformation. The skepticism dismissed by Son may fuel caution among some institutional investors, potentially leading to market corrections or segmentation of AI-related asset classes between established hardware players like Nvidia and emerging AI software ecosystems. However, if SoftBank’s projections materialize that AI will capture a meaningful share of the global GDP—potentially 10% or more—early and concentrated investments in companies like OpenAI could deliver substantial returns both financially and strategically.
Moreover, Son’s emphasis on the emotional difficulty of the decision and his public repudiation of bubble critics signal an intentional narrative positioning SoftBank as a visionary driver of AI innovation, willing to absorb short-term pain for longer-term gain. This could inspire confidence among investors and partners, especially in Japan and Saudi Arabia, as AI evolves under a framework supported by sovereign wealth funding and cross-border cooperation.
In summary, SoftBank’s Nvidia stake sale and subsequent AI investments illustrate a complex interplay of financial necessity, strategic foresight, and market dynamics shaping the AI investment landscape. Observers should monitor SoftBank's execution progress, OpenAI’s business restructuring, and the broader AI funding environment for indications of whether Son’s bold vision will translate into sustainable leadership in the AI-driven economy.
