SoftBank's ¥1.12tn quarterly loss can be checked. It is not a writedown of the OpenAI stake

On Nov. 10, 2026, SoftBank Group published results for the quarter ended September 30. The net loss attributable to owners, meaning the loss that belongs to SoftBank's shareholders, was ¥1,115,337 million. The company's own earnings slide labels that figure as $7.0 billion, using its quarterly rate of ¥160.12 per dollar. A year earlier, the same line was a profit of ¥2,502,247 million.

The Financial Times, in a story posted on its X account that day, used the headline "SoftBank posts unexpected $7bn loss as AI bet sours." The loss figure matches SoftBank's filing. The suggestion that the company's AI bet itself turned sour is broader than what the filing shows about OpenAI. This article could not retrieve the full FT text, which returned a security-verification page, so references to the newspaper are limited to that headline and the short opening lines visible in public indexes. The figures below come from SoftBank's official consolidated financial report and earnings presentation, dated the same day.

The checkable claim is narrow. SoftBank recorded a quarterly net loss of that size. In the same official package, it says a subsidiary, Silver Bands 7 LLC, had paid ¥1,500,886 million, or $9.48 billion, through September 30 to reserve manufacturing capacity and buy power-generation equipment for U.S. AI data-center projects, including the PORTS-Pike Technology Campus in Pike County, Ohio. After reviewing changes in the requirements of existing and planned projects, the company revised that procurement strategy. It booked a ¥597,248 million, or $3.73 billion, loss under "other gain and loss" for the six-month period. Of that amount, ¥457,030 million was a loss on advance payments the sellers will not refund, and ¥140,218 million came from changing or settling contracts.

SoftBank also says Silver Bands 7 obtained a right to discounts of up to $2.1 billion on future equipment purchases over the next 10 years, subject to conditions. Because the amount could not be fixed at period-end, the company did not record that right as an asset.

Two other lines in the three-month profit-and-loss statement help explain the swing, and neither is a writedown of the OpenAI stake. Finance costs were ¥461,917 million in the quarter, against ¥174,709 million a year earlier. The interim report says interest expense at SoftBank Group rose mainly because of large borrowings. Those included a $30 billion bridge loan, a short-term loan used for OpenAI installments, new bond issues, and an early repayment on September 15 that required remaining loan-setup fees to be recognized at once.

Investment gain and loss for the quarter was a loss of ¥133,586 million, compared with a gain of ¥3,439,720 million a year earlier. SoftBank states that, at September 30, its cumulative investment in OpenAI was $54.6 billion, the fair value, the price SoftBank assigned to the stake, was $99.6 billion, and the cumulative investment gain was $45 billion. It also states that this valuation was unchanged from March 31, 2026. A $10 billion third installment, completing a $30 billion follow-on committed on February 27, was funded on October 1, after the period ended. Only then did the cumulative amount reach $64.6 billion, with ownership of about 13 percent. That later check is not in the September 30 figures.

Net asset value, which SoftBank defines as the equity value of its holdings minus net debt, was ¥59.8 trillion, or $380 billion, at September 30. That is about ¥20 trillion higher than the ¥40.1 trillion recorded on March 31, and ¥12.5 trillion lower than the ¥72.3 trillion recorded on June 30. The company's loan-to-value ratio, net debt divided by the equity value of holdings, was 15.9 percent at September 30, still below its stated normal ceiling of 25 percent. Cash, on the definition SoftBank uses in that table, was ¥5.0 trillion, or $32 billion.

The "AI bet soured" frame invites a reader to treat the quarter as a writedown of SoftBank's best-known AI holding. The filing does not show that. What it does show is a large charge after the company paid ahead for power equipment and then changed plans, much higher financing costs, and a collapse in investment gains compared with a year earlier, when those gains were very large.

A fair counter-argument does not require an OpenAI writedown. Paying $9.48 billion in advances, then taking a $3.73 billion charge when project requirements changed, is evidence that the infrastructure build ran ahead of stable plans. The promised discount of up to $2.1 billion depends on future purchases and, by SoftBank's own account, is not yet an asset. Financing costs more than doubled in the quarter, in part because money was raised and refinanced to pay for OpenAI installments and the wider build. Net asset value also fell from its June 30 peak. Those facts can support worry about the cash and accounting cost of the AI build, even if the OpenAI carrying value did not move.

This article has not independently valued OpenAI, and cannot check whether the $99.6 billion fair value would hold in a new funding round or a sale. It also could not read the rest of the FT article, including any additional sourcing or share-price analysis that may appear there. The ¥597,248 million charge is reported for the six-month period. The quarterly "other" line was a loss of ¥669,923 million, which is large enough to contain that charge, but the report does not isolate the charge on the three-month statement itself.

For the next two quarters, the test is straightforward. If SoftBank records a lower official fair value for OpenAI, or takes further losses on power-equipment contracts, the narrower reading offered here would need to be revised. If the October installment is accompanied by a higher mark, and no further procurement charges appear, the second-quarter loss will look more like the cost of building and refinancing, not a collapse in the core holding. The unrecognized discount will matter only if future purchases are large enough, and qualified enough, to use it.

The $7.0 billion quarterly loss is in SoftBank's own accounts. The same accounts still carry the OpenAI stake at a $45 billion cumulative gain, with no valuation change from March 31. What soured in the filing is the cost of power equipment bought ahead of revised plans, and the cost of the debt used to fund the wider AI build. Those are the lines to watch in the next report, not a writedown that this quarter does not record.
