SoftBank’s OpenAI investment gains drive fourth consecutive profitable quarter
SoftBank is up 4% in premarket trading on Thursday as the Japanese conglomerate announced a net profit of ¥248.6 billion ($1.6 billion) in its fiscal third quarter, buoyed by a $4.2 billion valuation gain in its OpenAI investment.
SoftBank marked its fourth consecutive quarter of profits, swinging from a ¥369 billion ($2.4 billion) loss in the same quarter the year before.
The Masayoshi Son-led firm has invested a total of $34.6 billion in OpenAI so far, amounting to an ~11% stake in the startup, per its earnings presentation. The company is also reportedly looking to invest as much as $30 billion more in the ChatGPT-maker in a funding round that would value it at up to $830 billion.
SoftBank is accumulating more dry powder to fund its investments in OpenAI and other AI-adjacent ventures. Management shared on Thursday that they sold $12.7 billion worth of T-Mobile shares between June and December 2025, offloading an additional $2.3 billion in January of this year. In addition, they borrowed another $400 billion via a margin loan that uses SoftBank Corp. shares in December.
Since SoftBank started investing in OpenAI through the end of 2025, the company has enjoyed a $19.8 billion investment gain in total. The OpenAI investment, alongside other investments in its second tech-heavy Vision Fund, drove a $6.5 billion increase in fair value for the quarter — helping to outweigh a $4.1 billion loss in its first Vision Fund, “primarily due to share price declines of Coupang and DiDi.”
BTIG analyst Jesse Sobelson estimates that the ChatGPT maker now represents 30% of SoftBank’s net asset value. The company’s stock has also almost doubled in the past year as retail investors piled into SoftBank to get pseudo-exposure to the now-private OpenAI.
