SoftBank Wants $100 Billion From the Gulf, Weeks After Paying 9.75% to Borrow for OpenAI

Less than three weeks ago SoftBank paid up to 9.75% to borrow money in the junk bond market. This week the Financial Times reported that its founder is asking Gulf investors for up to $100 billion more. The two facts belong in the same sentence, because together they show what the price of AI capacity looks like once the cheap money has been spent.

What Actually Happened

On October 9, Reuters relayed an FT report that SoftBank Group CEO Masayoshi Son is seeking to raise up to $100 billion from Gulf investors to fund a new wave of AI investments. Ad Hoc News, which also summarized the Reuters piece, says Reuters noted it could not immediately verify the figures.

Mobile World Live, citing the same FT report, fills in the shape of the plan. Son has been in discussions with senior figures across the Middle East, including in the UAE. The FT said there is no guarantee the talks will lead anywhere, and it did not name any companies or individual investors. The money would reportedly set up a fund to buy companies and then use AI and other advanced technology to improve how they run. Mobile World Live adds that SoftBank's AI and robotics business, Roze, is expected to play a key role, and that SoftBank plans to take that unit public.

A caution on sourcing. Reuters, The Information, Yahoo Finance and Mobile World Live all point back to one FT story, which cites people familiar with the talks. We could read the Mobile World Live and Ad Hoc News summaries but not the FT original or the full Reuters text. Treat the $100 billion as a reported ambition, not a closed raise.

Gulf money is not new to Son. Mobile World Live notes that UAE sovereign wealth fund Mubadala and Saudi Arabia's Public Investment Fund partnered with SoftBank on its original Vision Fund in 2017, and that UAE-based G42 and MGX are already putting large sums into AI development.

The Bill Behind the Ask

The size of the request makes more sense next to what SoftBank has already committed. According to DigitalToday, citing ITmedia, SoftBank agreed with OpenAI on February 27 to invest $30 billion through SoftBank Vision Fund 2 in three $10 billion tranches. Those were paid on April 1, July 1 and October 1. The first two were funded with bridge loans from banks. The third came from corporate bond proceeds.

That bond sale was the record. Reuters reported on September 24 that SoftBank was issuing $11.1 billion in dollar and euro bonds, set to be the largest high-yield corporate bond sale on record. Crypto Briefing gives the breakdown:

• Dollar notes: $10 billion in three tranches. $1 billion at 3.5 years priced at 8.625%, $4.5 billion at 5.5 years at 9.25%, and $4.5 billion at 7.5 years at 9.75%.
• Euro notes: two €500 million tranches, at 7.125% over four years and 8% over six years.
• Prior record: Numericable's roughly $10 billion issuance in 2014, per the same source.
• Demand: the deal was reportedly oversubscribed.

By our arithmetic, $4.5 billion at 9.75% is roughly $439 million a year in interest on that one tranche, before any other debt. Crypto Briefing also reports that SoftBank had secured about $40 billion in bridge loans earlier in the year, and that the bonds refinance part of that debt.

With the final tranche paid, DigitalToday and Crypto Briefing both put SoftBank's cumulative OpenAI investment at $64.6 billion, for a stake of about 13%.

Why the Timing Is Awkward

The OpenAI position is now the largest single exposure on SoftBank's balance sheet, and the number underneath it moved last week. On Thursday, Reuters reported that OpenAI told investors its annualized revenue was approaching $50 billion at the end of September, well below the roughly $70 billion that had circulated. We covered the definitions dispute behind that gap on Friday. The FT's explanation was a counting difference with Anthropic, not lost sales, and Bloomberg later reported OpenAI expects at least $70 billion by year-end.

The explanation may be benign, but the market reaction was not. Ad Hoc News reports SoftBank shares stood at EUR 32.27 at Friday's close in European trading, down 12% over seven sessions. That figure comes from a single source, and we have not matched it against an exchange feed.

Ad Hoc News also reports SoftBank said on Thursday that it would redeem all €405.1 million of its 2.875% senior notes due January 2027 at par on October 22, and that its net asset value was JPY 72.3 trillion at the end of June. Those are real cushions. They also say something about direction: old 2.875% paper is being retired while new paper prices at 8% to 9.75%.

Three Layers of Financing, Three Prices of Risk

Read as a sequence, the OpenAI financing has moved through three layers, and each one asks a different group to hold the risk.

Bank bridge loans funded the first two tranches. Banks were short-term lenders, expecting to be refinanced.

High-yield bond buyers took the refinancing. They accepted yields near 10% and, per Crypto Briefing, oversubscribed the deal. That tells you credit investors will lend into AI exposure if they are paid for it. It also tells you how much they are paid.

Gulf sovereign and strategic capital is the layer now being sought, and it is a different kind of money. It would be equity in a vehicle that buys operating companies, not a loan against SoftBank's balance sheet. Investors would be underwriting Son's thesis that AI can raise the margins of acquired businesses. That is a separate bet from the one on OpenAI's growth.

The pattern echoes what we saw with SpaceX's chip financing, where the buyer carries the obligation so the vendor can book the revenue. Here the buyer is a Japanese holding company, the vendor ecosystem is OpenAI and its suppliers, and the obligation is being passed to progressively more patient capital. The same supply chain includes Nvidia, which has backed OpenAI's own build-out in places like the Ohio data center campus.

What the $100 Billion Is Not

It is not a new model, a new data center or a new customer. If the fund is built as reported, it buys existing companies and tries to make them more efficient with AI. That is a services-and-operations thesis, and its returns depend on whether AI lowers costs inside the acquired businesses, not on how fast OpenAI's revenue grows.

That distinction matters because the market is currently pricing AI exposure on the revenue side. OpenAI's reported revenue, as we have seen, can swing by $20 billion depending on the definition. An operations-improvement fund would be judged on margins, which are audited. If Gulf investors commit, they would be moving from a bet on a growth narrative to a bet on execution.

It is also not certain. The FT itself said no deal is guaranteed, no investors were named, and Ad Hoc News frames the Gulf partners as hesitant, noting firm commitments have yet to materialize. Both are the publisher's characterizations, not confirmed facts. Until a Gulf investor or SoftBank says something on the record, the $100 billion is a number in a negotiation.

What Builders Should Take From It

• Track the cost of capital behind your vendors. A lab financed at 9.75% has different incentives from one funded by retained cash. Price increases, usage caps and contract terms eventually follow the interest bill.
• Do not size your roadmap to a funding headline. SoftBank's $100 billion is reported, unconfirmed and unnamed. Treat it as a signal of appetite, not a guarantee of capacity coming online.
• Separate OpenAI exposure from SoftBank exposure. If you depend on OpenAI, SoftBank's financing strain is not your counterparty risk today. If you sell to SoftBank portfolio companies, check their runway assumptions.
• Keep a second model provider tested. The same investors are funding multiple labs, and a sentiment swing in one reaches all of them. Portability is cheaper to build now than during an outage.
• Watch for the Gulf response. A named UAE or Saudi commitment would confirm that sovereign money is willing to take equity risk where bond buyers took credit risk. A quiet denial would say the opposite.
