SoftBank Cuts OpenAI Margin Loan Target by 40%

SoftBank Group has slashed its target for a margin loan backed by its OpenAI stake by 40%, reducing the planned borrowing from $10 billion to $6 billion. The dramatic reduction comes as some creditors have expressed reluctance to participate in what would still be one of the largest single-asset margin loans in recent memory.

The deal, first reported on May 8, remains in active negotiations, and final terms — including the ultimate loan size — could still shift. But the significant pullback signals growing caution among lenders about the risks of extending massive credit against private AI company equity.

Key Takeaways at a Glance

• SoftBank originally sought $10 billion in loans backed by its OpenAI holdings
• The target has been reduced to $6 billion, a 40% decrease
• Some creditors are hesitant to participate in the deal
• Negotiations are ongoing and final terms may still change
• The loan would use SoftBank's OpenAI equity stake as collateral
• This comes amid SoftBank's broader strategy to dominate the AI infrastructure space

Why Creditors Are Pulling Back

The reluctance among certain lenders reflects a fundamental tension in AI finance: while OpenAI is arguably the most high-profile AI company on the planet, its shares remain privately held and difficult to value with precision. Unlike publicly traded stocks that serve as collateral for traditional margin loans, OpenAI equity lacks the liquidity and transparent pricing that lenders typically require.

Creditors evaluating the deal must weigh several risk factors. OpenAI's valuation has fluctuated significantly over the past 18 months, soaring from roughly $80 billion to as high as $300 billion in some recent funding discussions. That kind of volatility — even in an upward direction — makes it challenging for banks to set comfortable loan-to-value ratios.

There is also the question of concentration risk. A $6 billion loan secured by a single private company's equity represents an enormous bet on one asset. If OpenAI were to face a significant valuation markdown, the collateral backing the loan could deteriorate rapidly, leaving lenders exposed to substantial losses.

SoftBank's Aggressive AI Investment Strategy

The margin loan attempt is part of SoftBank CEO Masayoshi Son's broader campaign to position the Japanese conglomerate at the center of the global AI revolution. Son has repeatedly described artificial intelligence as the most important technological shift in human history, and he has been deploying capital at an extraordinary pace to back that conviction.

SoftBank's relationship with OpenAI deepened significantly in early 2025. The company committed billions to OpenAI's latest funding round, acquiring a substantial equity position. That investment came alongside SoftBank's involvement in Stargate, the ambitious $100 billion AI infrastructure project announced in partnership with OpenAI, Oracle, and other major players.

Son's strategy mirrors his approach during the mobile internet era, when he made a legendary early bet on Alibaba that generated returns of over $70 billion. However, his track record also includes the Vision Fund era, marked by high-profile failures like WeWork that cost investors billions. The margin loan — even at the reduced $6 billion level — represents another high-conviction, high-concentration wager.

How This Compares to Other AI Financing Deals

The SoftBank-OpenAI margin loan, even at $6 billion, would stand out as an unusually large transaction in the AI financing landscape. For context, consider these recent deals:

• Anthropic raised $2 billion from Google in a direct equity investment in 2023
• xAI, Elon Musk's AI startup, secured $6 billion in its Series B round in late 2024
• Microsoft's cumulative investment in OpenAI has reached approximately $13 billion
• CoreWeave, the AI cloud provider, arranged $7.5 billion in debt financing for GPU infrastructure
• Traditional margin loans against public tech stocks rarely exceed $2-3 billion for single borrowers

What makes SoftBank's attempt distinctive is the use of private equity as collateral for debt — a structure more commonly seen in leveraged buyouts than in technology sector financing. The hybrid nature of the transaction has clearly given some potential lenders pause.

Unlike margin loans backed by publicly traded shares, where lenders can quickly sell collateral if values decline, a loan backed by OpenAI shares offers no such easy exit. The secondary market for OpenAI shares, while growing, remains far less liquid than public equity markets.

The Broader Implications for AI Valuations

The creditor pushback carries implications that extend well beyond SoftBank's balance sheet. It suggests that the financial sector is beginning to apply more rigorous scrutiny to AI company valuations, even for the industry's most prominent names.

For much of 2023 and 2024, the AI sector benefited from what some analysts described as a 'valuation premium' — investors and lenders were willing to accept higher multiples and thinner margins of safety because of the transformative potential of the technology. The SoftBank loan negotiation may indicate that this premium is starting to narrow, at least among debt providers who must think carefully about downside scenarios.

This development also raises questions about the sustainability of AI mega-deals. If lenders are cautious about extending $10 billion against OpenAI equity — the crown jewel of the AI startup world — it could signal broader tightening for other AI companies seeking debt financing. Smaller AI startups that have relied on their inflated valuations to secure favorable lending terms may find the environment becoming considerably more challenging.

What This Means for the AI Industry

The ripple effects of this deal could influence several stakeholders across the AI ecosystem:

• AI startups may face tougher scrutiny when using equity as loan collateral
• Venture capitalists could see pressure on late-stage AI valuations if debt markets tighten
• SoftBank's Stargate commitments could be affected if the company cannot raise capital as efficiently as planned
• OpenAI itself may need to consider how its private status affects its partners' ability to leverage their holdings
• Public market investors may view this as a signal about private AI company valuation risks
• Competing AI firms like Anthropic and Google DeepMind may benefit if SoftBank's capital deployment slows

For developers and businesses building on OpenAI's platform, the immediate impact is likely minimal. However, the financing dynamics at the investor level can eventually trickle down to affect product pricing, API availability, and the pace of infrastructure buildout.

Looking Ahead: What Happens Next

Several key questions remain unanswered as negotiations continue. The most critical is whether SoftBank will accept the reduced $6 billion figure or continue pushing for a larger facility. Masayoshi Son is known for his persistence and willingness to restructure deals creatively, so further modifications to the loan terms are entirely possible.

One potential path forward involves SoftBank offering additional collateral beyond its OpenAI stake. The company holds significant positions in Arm Holdings, the chip design firm that has seen its stock surge on AI demand, as well as stakes in numerous other technology companies. Bundling multiple assets could give creditors the diversification and liquidity comfort they need.

Another possibility is that SoftBank could pursue a syndicated approach, breaking the loan into smaller tranches distributed among a wider group of lenders. This would reduce individual bank exposure and might make participation more palatable for institutions that are wary of taking on a large concentrated position.

The timeline for resolution remains unclear. Sources indicate that discussions are actively ongoing, and market conditions — including any developments in OpenAI's business trajectory or potential IPO plans — could significantly influence the final outcome. If OpenAI moves closer to a public listing, the liquidity concerns that are currently giving creditors pause could evaporate, potentially reopening the door to a larger facility.

For now, the 40% reduction serves as a reminder that even in the most heated AI market in history, financial discipline has not been entirely abandoned. The lenders' caution may ultimately prove beneficial for the broader ecosystem, ensuring that the AI boom's financial architecture rests on foundations more solid than unbounded optimism alone.
