SoftBank's 70% AI rally masks mounting debt crunch concerns

SoftBank Group Corp.'s shares have surged about 70% this year on artificial intelligence enthusiasm, yet its concentrated bets on OpenAI and mounting debt are reviving liquidity crunch concerns, according to a CNBC report Wednesday.

The concerns center on SoftBank's ability to service its debt load as it pours capital into AI infrastructure, including the Stargate initiative backed by OpenAI and SoftBank, the report said. Chief Executive Masayoshi Son has framed the AI push as a generational opportunity after a string of failed bets left the company in a precarious position.

SoftBank's shares have rallied as investors cheered its pivot toward AI, with the stock gaining roughly 70% year to date. But the company's debt levels have climbed in tandem as it finances large-scale investments, including its stake in OpenAI and commitments to data center buildouts. Oracle Corp., a key partner in the Stargate project, carries about $135 billion in outstanding loans and debt, a sign of the capital intensity required in the AI infrastructure race.

If AI valuations cool or anticipated revenue from these investments takes longer to materialize, SoftBank could face margin calls or be forced into asset sales to raise cash, the report suggested. The company's ability to manage its debt while maintaining aggressive AI spending will be a key test for Son's turnaround strategy.

Son's High-Stakes Pivot

Son's track record with leveraged bets has drawn scrutiny before. The SoftBank Vision Fund suffered billions in losses during the 2022 tech downturn, with high-profile bets on WeWork and Uber failing to deliver expected returns. The current AI push represents a higher-stakes wager, with capital commitments that far exceed those earlier ventures. Unlike the Vision Fund era, where SoftBank deployed capital across hundreds of startups, the AI strategy concentrates risk in a smaller number of large-scale infrastructure projects and partnership deals.

The Stargate Exposure

SoftBank's role in Stargate, the massive AI infrastructure initiative, adds another layer of financial exposure. The project requires billions in upfront capital with returns spread over years. Oracle's backlogged orders have climbed 325% year over year to $553 billion, driven by multi-year AI infrastructure deals, but the company also faces $135 billion in debt — a tension that mirrors SoftBank's own balance sheet challenge. For SoftBank, the risk is that Stargate and similar projects require sustained capital infusions before generating meaningful cash flows, potentially straining liquidity in the interim.

Forward Outlook

The trajectory of SoftBank's debt burden will depend on the pace of AI revenue growth and the broader interest rate environment in Japan. With the Bank of Japan signaling potential rate hikes, SoftBank's yen-denominated debt servicing costs could rise, adding pressure to an already stretched balance sheet. Investors will be watching Son's next moves closely as the gap between AI ambition and financial reality narrows.
