NextFin News - SoftBank Group Corp. reported a significant financial turnaround on February 12, 2026, swinging to a net profit of 248.59 billion yen ($1.62 billion) for the fiscal third quarter ended December 31, 2025. This performance, marking the company’s fourth consecutive profitable quarter, was primarily fueled by a staggering 2.8 trillion yen ($19.8 billion) valuation gain from its investment in OpenAI. According to Bloomberg, SoftBank’s aggregate ownership in the AI powerhouse now stands at approximately 11%, following a series of massive capital injections including a $22.5 billion installment completed in late December 2025. This strategic shift comes as U.S. President Trump’s administration continues to emphasize American leadership in critical technologies, creating a high-stakes environment for global tech investors like Masayoshi Son.
The financial resurgence of SoftBank is a direct result of Son’s "all-in" gamble on artificial intelligence. To fund this vision, the Tokyo-based conglomerate executed a series of aggressive divestments, including the complete sale of its $5.8 billion stake in Nvidia and a substantial portion of its T-Mobile US holdings. These moves provided the liquidity necessary to fulfill a $41 billion total commitment to OpenAI. SoftBank Chief Financial Officer Yoshimitsu Goto emphasized that the group’s investment is rooted in high conviction regarding OpenAI’s leadership in the sector, though he noted that "nothing concrete has been decided" regarding rumored additional funding rounds that could value the startup at upwards of $800 billion.
For Son, the benefits of this OpenAI bet extend beyond mere balance sheet recovery. By securing an 11% stake, SoftBank has effectively become the primary public vehicle for investors seeking exposure to OpenAI’s private valuation surges. This positioning allows Son to regain his status as a global tech visionary after the high-profile setbacks of the Vision Fund’s earlier years. The valuation boost from OpenAI has not only offset losses in other portfolio companies like Coupang but has also provided the collateral needed to expand SoftBank’s borrowing capacity. The company recently increased its margin loan facility backed by Arm shares to $20 billion, further leveraging its most successful assets to fuel new AI infrastructure projects.
However, this concentration of capital introduces a precarious "single-point-of-failure" risk. OpenAI now represents roughly 30% of SoftBank’s net asset value, tethering the Japanese firm’s stock price to the performance of ChatGPT and its ability to outpace rivals like Google’s Gemini and Anthropic’s Claude. Analysts from BTIG suggest that while SoftBank is the "only real way to play OpenAI" in public markets, the rising costs of training large language models and the intense competitive landscape pose a threat to long-term profitability. If OpenAI’s valuation were to plateau or retract, SoftBank’s highly leveraged structure could face renewed pressure from credit rating agencies, which have already warned about the company’s narrowing liquidity margins.
Looking ahead, Son’s strategy appears focused on building a vertically integrated AI empire. Beyond the OpenAI stake, SoftBank has recently acquired chip designer Ampere Computing for $6.5 billion and private equity firm DigitalBridge for $3 billion to bolster its data center and robotics capabilities. This "Stargate" push, a $500 billion initiative alongside OpenAI and Oracle, aims to build the physical infrastructure required for the next generation of AI. While the immediate benefit to Son is a restored reputation and a profitable exit from the "winter" of 2023-2024, the ultimate success of his bet will depend on whether OpenAI can transition into a sustainable, high-margin enterprise amidst evolving regulatory scrutiny in both the U.S. and Japan.
