SoftBank’s Ambitious AI Strategy: Eyeing a Major Expansion in OpenAI

SoftBank JP3436100006

The appetite for artificial intelligence investments at SoftBank Group appears far from satisfied. Fresh reports indicate that the Japanese technology conglomerate, led by Masayoshi Son, is negotiating a dramatic increase in its stake in OpenAI. This potential move could involve a staggering new commitment of capital, pushing the valuation of the ChatGPT creator to unprecedented levels and raising questions about the financial implications for SoftBank.

According to information from Reuters citing people familiar with the matter, SoftBank is currently in discussions to invest an additional sum of up to $30 billion. This colossal figure would form part of a broader funding round aimed at securing OpenAI as much as $100 billion in new capital. Should a deal of this magnitude be finalized, it would propel the AI pioneer's valuation to approximately $830 billion.

Investors will soon gain clearer insight into the financial sustainability of this aggressive posture. SoftBank is scheduled to announce its results for the third quarter of fiscal year 2025 on February 12, 2026. Market attention will be firmly fixed on the company's liquidity position and the impact of substantial capital outflows directed toward its AI holdings.

This potential new investment underscores CEO Masayoshi Son's uncompromising strategic focus on the artificial intelligence sector. The group only recently finalized a $41 billion investment in OpenAI in December 2025, securing an approximate 11 percent ownership stake. The two firms are also collaborating on "Stargate," a $500 billion initiative focused on constructing advanced AI data centers.

Structural Changes and Resource Allocation

However, this rapid expansion consumes enormous resources. Reports suggest that mobilizing funds for the initial investment tranche in December required significant effort, nearly bringing other activities of the Vision Fund to a standstill. The capital demands remain high on both sides: OpenAI is contending with rising costs for training new models and intense competitive pressure from rivals like Google.

SoftBank has also implemented structural changes recently. A 4:1 stock split took effect in early January, increasing the number of outstanding shares to 5.71 billion. This maneuver was designed to make the stock appear more affordable and accessible to a broader base of investors.

The central question for stakeholders now is whether SoftBank can sustain such an ambitious and capital-intensive strategy as it seeks to deepen its influence in one of the world's most prominent AI companies.
