Seldom has a single investment so profoundly reshaped the fortunes of a global conglomerate. SoftBank Group reported a $46 billion yearly gain at its Vision Fund for fiscal year 2025. The windfall was driven overwhelmingly by the surging valuation of its stake in OpenAI. This unprecedented result validates CEO Masayoshi Son's audacious pivot toward artificial intelligence.

SoftBank has committed approximately $64.6 billion to OpenAI, securing roughly 13 percent ownership of the company. More than $30 billion had already been deployed by March 2026. OpenAI's valuation rocketed from $157 billion in October 2025 to $852 billion by March. That remarkable trajectory yielded a cumulative floating profit of approximately $45 billion on SoftBank's holdings.

Nevertheless, the concentration risk inherent in this strategy has not gone unnoticed. Approximately 98 percent of the Vision Fund's annual return derived from a single asset. Holdings in Coupang, DiDi Global, and Klarna actually eroded overall performance. S&P Global Ratings consequently revised SoftBank's credit outlook from stable to negative in March.

To finance its expanding AI commitment, SoftBank has been divesting positions in T-Mobile and Nvidia. The company arranged a $40 billion bridge loan facility, of which $20 billion had been drawn by April. CFO Yoshimitsu Goto sought to reassure investors by highlighting a 3.5 trillion yen liquidity cushion. He emphasized that this reserve could cover more than two years of bond redemptions.

The broader implications for the investment landscape are considerable. SoftBank's results demonstrate that concentrated bets on category-defining AI firms can generate extraordinary returns. Yet the sustainability of such gains remains contingent upon OpenAI maintaining its competitive edge. With rivals like Google and Anthropic intensifying their efforts, the question of portfolio diversification looms large.
