SoftBank wrote off $3.73 billion of equipment bought for American AI data centres.

A SoftBank subsidiary had already paid $9.48 billion for that equipment, then changed its plan. Of the write-off, $2.85 billion was advance payments it cannot get back.

Until now

Buying scarce power gear early is how you win the AI build.

Now

Prepaying for gear your plan then outgrows is a cash loss.

Why it matters

Everyone building AI capacity is prepaying for scarce equipment years ahead. SoftBank just published the bill when a plan changes: $2.85 billion of advance payments written off, and rebates of up to $2.1 billion it refused to book because it could not measure them.

Established

SoftBank recognised a 597,248 million yen loss on revised equipment procurement.
457,030 million yen of that was non-refundable advance payments.
Silver Bands 7 had paid 1,500,886 million yen for equipment by September 30.

Not established

That the Ohio campus is cancelled. SoftBank is reported to deny it.
What the equipment was, or which manufacturers hold the money.
Whether any rebate will ever be received.

The record

SoftBank Group published its consolidated financial report for the 6 months ended September 30, 2026, dated November 10, 2026 in Tokyo. We read the report ourselves. Net loss attributable to owners of the parent for the 6 months was 768,007 million yen. The report states that Silver Bands 7 LLC revised its equipment procurement strategy and that the company recognised a loss of 597,248 million yen, given as $3.73 billion, in other gain and loss. The loss has 2 components: 457,030 million yen, $2.85 billion, for non-refundable advance payments, and 140,218 million yen, $0.88 billion, for contract modifications and settlements. Silver Bands 7's cumulative procurement payments from the previous fiscal year through September 30, 2026 totalled 1,500,886 million yen, $9.48 billion. The report says Silver Bands 7 may receive rebates of up to $2.1 billion over the next 10 years on future equipment purchases, subject to conditions, and that because the amount could not be determined no rebate asset was recognised. Consolidated finance cost was 790,662 million yen, up 450,644 million yen year on year, with SoftBank Group's own interest expense at 676,389 million yen, up 407,217 million, attributed to new borrowings and higher funding rates. On OpenAI, the report says follow-on investments totalling $30.0 billion were completed in October 2026, that cumulative investment at quarter end was $54.6 billion against a fair value of $99.6 billion, and that after the October tranche cumulative investment reached $64.6 billion for about 13% ownership, carried at 15,671.5 billion yen. Reuters, reporting the same day, put the quarterly net loss at about 1.1 trillion yen, roughly $7 billion, against a 2.5 trillion yen profit a year earlier, and said 3 analysts polled by LSEG had expected anything from a 233 billion yen profit to a 113 billion yen loss. Not in the report: what the equipment was, who sold it, and whether the Ohio campus changes size. SoftBank executives are reported to have said it is not being abandoned or downsized.

How it got here

Oct 2026
SoftBank completes follow-on investments of $30.0 billion in OpenAI, fulfilling the commitment it made in February, taking cumulative investment to $64.6 billion for about 13%.

Nov 10
The 6 month consolidated financial report discloses the 597,248 million yen Silver Bands 7 loss, a 768,007 million yen net loss attributable to owners, and finance cost up 450,644 million yen.

Who has to react

The turbine and transformer makers holding SoftBank's prepayments; OpenAI, whose largest outside backer just reported this; the banks lending against SoftBank's Arm stake; Pike County, Ohio; every data centre developer that has prepaid for equipment on a plan it may revise; and the auditors who will test the $2.1 billion of unbooked rebates.

What to watch

Would strengthen itA second company building AI data centres writes off more than $1 billion of equipment prepayments, or publicly cancels placed equipment orders, by June 30, 2027.
Would weaken itSoftBank reports that Silver Bands 7 has recovered the rebates, or discloses equipment deliveries at the Ohio site with no further procurement loss, by December 31, 2027.
Would strengthen itSoftBank's next 2 quarterly reports carry no further equipment or procurement losses at any subsidiary, by August 31, 2027.

PersistenceYear

Cost is high. This is not a mark on paper. 457,030 million yen of cash was handed over and will not come back, against cumulative procurement of 1,500,886 million yen. Commitment is medium: a write-off records a decision already taken rather than binding the group to a new course, and SoftBank says the Ohio project continues. Reversibility is low, because spent cash cannot be unspent and the rebates that might soften it require buying more equipment from the same suppliers. Persistence is years rather than structural: the charge lands in one quarter, but the procurement book behind it runs for years and the same test will be applied to it again.

The words

Non-refundable advance payment: Money paid up front to hold a place in a manufacturer's queue. If you walk away, the maker keeps it.
Rebate: A discount promised on future purchases. It is worth nothing unless you buy again, which is why SoftBank did not record one.
Silver Bands 7: The SoftBank subsidiary that buys equipment for American AI computing projects, including a proposed campus in Pike County, Ohio.
Other gain (loss): The income statement line where one-off items sit, outside normal trading. A loss here still means real money.
