SoftBank Credit Outlook Downgraded After Doubling Down on OpenAI with $30 Billion Investment

S&P Global Downgrades SoftBank Credit Outlook Amid Massive OpenAI Bet

S&P Global has revised SoftBank's credit outlook from stable to negative, citing concerns over the Japanese investment firm's aggressive expansion into OpenAI. After already injecting more than $30 billion into the ChatGPT maker last year, SoftBank announced plans last month to deploy an additional $30 billion OpenAI bet throughout the current year1

. The ratings agency maintained SoftBank's BB+ long-term issuer credit rating but warned that the deepening SoftBank investment in the AI startup could significantly impact the company's financial stability.

The additional investment will be deployed through three separate $10 billion tranches over the course of the year, lifting SoftBank's stake in OpenAI to 13% from around 11% in December2

. Following this commitment, OpenAI will represent 30% of SoftBank's investment assets—matching its holdings in Arm, the UK-based chip designer1

. The expanded investment portfolio will likely exceed $320 billion, positioning it among the world's largest1

Concerns Over Credit Quality and AI Innovation Risk

S&P Global identified OpenAI as one of SoftBank's investments with the "weakest" credit quality, a designation that has amplified concerns about the firm's strategic direction1

. The ratings agency noted that SoftBank's AI investments predominantly involve fledgling startups and private companies, including SambaNova, Wayve, and ABB Robotics, exposing the firm to significant AI innovation risk and fierce competition1

The S&P credit outlook revision reflects growing unease about portfolio liquidity. The proportion of unlisted shares in SoftBank's portfolio is expected to soar above 50% from an estimated 42% in December, further reducing liquidity2

. "The negative outlook reflects our view that SoftBank Group's large follow-on investment in OpenAI means it will take longer than we had assumed for the company to restore the liquidity and quality of its investment assets," S&P stated1

Impact on Loan-to-Value Ratio and Financial Pressure

The additional OpenAI commitment threatens to worsen SoftBank's loan-to-value ratio, a metric the company has used for years to demonstrate its debt repayment capacity2

. Bloomberg Intelligence suggests that SoftBank will need to bring its adjusted LTV below 35% to defend its BB+ rating, potentially requiring substantial asset sales2

SoftBank has already demonstrated willingness to liquidate holdings to fund founder Masayoshi Son's AI ambitions. Last November, the firm sold all of its shares in Nvidia, valued at around $5.2 billion, and previously divested stakes in T-Mobile US Inc.1

. At the time, chief financial officer Yoshimitsu Goto emphasized the company's conviction in OpenAI and Arm, stating, "Together, Arm and OpenAI are powering SoftBank Group toward our goal of becoming the number one platform provider for the artificial superintelligence era"1

What Lies Ahead: OpenAI IPO and Asset Sales

An OpenAI IPO would provide critical relief for SoftBank's strained investment portfolio and improve portfolio liquidity1

. S&P indicated it would consider revising the outlook upward if liquidity improves through initial public offerings of assets including OpenAI, while SoftBank simultaneously maintains investment portfolio quality and enhances its loan-to-value ratio through asset sales2

.

However, execution faces hurdles. Bloomberg Intelligence warns that heightened geopolitical risk and a potential AI bubble could pressure technology valuations, keeping LTV weak and potentially delaying OpenAI's already uncertain listing timeline2

2

. S&P noted that while SoftBank may take measures to ease its financial burden through asset sales, "the timing and scale of those measures remain uncertain"1

. The ratings agency added that "pressure on the ratings will increase if SoftBank Group fails to take swift easing measures, such as selling holdings"2
