SoftBank Group has returned to profitability for the third fiscal quarter of 2025, signaling a decisive turnaround fueled by a massive bet on artificial intelligence. The Japanese investment giant reported a net profit of 248.6 billion yen (approximately $1.62 billion) for the October–December period. This result marks the company’s fourth consecutive profitable quarter, a sharp recovery from the 369 billion yen loss recorded during the same period a year ago. The primary driver of this growth is the surging valuation of OpenAI. SoftBank’s investment in the ChatGPT creator has generated a staggering 2.8 trillion yen ($19.8 billion) in gains over the first nine months of the fiscal year. SoftBank has currently invested over $30 billion in OpenAI, securing an 11% ownership stake. Reports indicate the group is in talks to invest up to an additional $30 billion in a new funding round that could value OpenAI between $750 billion and $830 billion. The Vision Fund segment, once a source of significant losses, recorded a profit of 735.49 billion yen this quarter. This reversal was bolstered by OpenAI’s appreciation, which helped offset weaker performance in other parts of the portfolio. Beyond its direct startup bets, SoftBank’s subsidiary, Arm Holdings, is playing a critical role in its financial narrative. Arm recently reported record quarterly revenue of $1.24 billion, driven by a 27% increase in royalty revenue as its architecture becomes central to AI data centers. To maintain its aggressive investment pace, SoftBank has been liquidating other major assets. Between June and December 2025, the group sold its $5.8 billion stake in Nvidia and a portion of its T-Mobile holding for $12.73 billion. The company is also pivoting toward infrastructure. In late 2025, SoftBank committed to acquiring Swiss robotics firm ABB for $5.4 billion and land from Sharp for 100 billion yen to build large-scale AI data centers. Despite the positive momentum, SoftBank missed the average analyst profit estimate of 336.7 billion yen. Investors remain focused on the company’s rising leverage, as it continues to secure loans against its Arm holdings to fund its ambitious AI "all-in" strategy.
