Original title: Can AI data centers still borrow cheap money?
TL; DR
· Alphabet's new round of corporate bonds has attracted about $115 billion in subscription demand, and plans to raise up to $25 billion to supplement AI infrastructure construction capital.
· After abandoning the €1 billion bond program, Pure DC switched to bank financing, and the pricing of data center debt is becoming more expensive.
· The market disagreement is not whether AI infrastructure can be funded, but rather that financing costs and bargaining power between different borrowers are widening.

Google's parent company Alphabet's massive bond offering attracted around $115 billion in subscription demand. Earlier market news showed that Alphabet is preparing to issue a new round of US corporate bonds. It plans to raise up to 25 billion US dollars. The bonds can be divided into up to 10 tiers, with a term of 2 to 40 years, and the final scale is yet to be determined. This funding will supplement Google's continued expansion of AI infrastructure.
On almost the same line, Pure Data Centres Group abandoned the original plan to issue €1 billion bonds in July and switched to bank financing. Some data center mortgage transactions also need to increase yield in order to attract buyers to complete subscriptions.
Looking at these two things together, AI infrastructure financing has not stopped, but the debt market is being stratified. Tech giants with the strongest balance sheets and clearest credit qualifications can still attract large-scale capital; while data center developers, which rely more on project cash flow and capital market windows, are beginning to face more picky bond buyers.
This incident affects the pricing of AI assets because data centers are not built solely on technological narratives. It needs to continue to borrow money, rent land, connect electricity, and purchase equipment, and turn future rent and computing power requirements into today's financing capabilities.
The current dispute is not whether AI funding will be interrupted. High-quality projects can still receive credit funds from banks, institutions, and private sources. The change is that the open market is beginning to recalculate accounts based on credit assets: who the borrower is, whether the lease is strong enough, whether electricity costs will get out of control, and whether the cash flow can cover the debt.
The open bond market is not closing, but is beginning to stratify
The fact that Alphabet bonds received approximately $115 billion in subscription requirements is an important sign. It shows that as long as the issuer is strong enough and the market believes in its cash flow and solvency, AI infrastructure-related financing can still obtain a large number of purchases.
But that doesn't mean that all AI data center debts get the same treatment. Alphabet issues US corporate bonds, and behind them are the tech giants' own credit credentials; Pure DC is facing a data center financing environment that is closer to pricing cash flow for projects and assets. The two are part of the same AI infrastructure chain, but they are not the same kind of risk.
The most immediate change is that some borrowers are still getting more expensive to borrow money. Widening interest spreads mean investors are demanding a higher additional yield than treasury bonds or benchmark interest rates. For borrowers, this is an increase in financing costs.
According to Bloomberg Law July 21, Oaktree-backed Pure DC dropped the proposed €1 billion bond and switched to bank financing. The same report also mentioned that of the data center securities issued since the beginning of last year, nearly 80% of the current quoted interest spreads are higher than when they were issued.
This is not a funding freeze. The buyer is still there, only the price has changed. Investors are willing to buy AI data center debt, but are unwilling to continue using previous low-risk assumptions.
The Pure DC case also needs to be viewed in the context of a complete financing rhythm. The company announced in May that it had secured financing of 2.7 billion US dollars, and in July it also announced that it had obtained 1.3 billion euros of senior debt for the first phase of the Seinäjoki AI Park in Finland. It's not that it can't get money; the open bond market is no longer a frictionless export.
AI infrastructure changes from a growth story to a credit story
Over the past two years, the stock market has been more concerned about whether AI demand will continue, whether there will not be enough chips, and whether models will continue to expand. But for debt investors, the question is more straightforward: who will pay back the money, when, and how stable the cash flow is.
Issuance such as Alphabet can attract huge subscriptions. Essentially, the market is willing to price AI infrastructure investment within the overall credit framework of large technology companies. Investors are buying more than just one data center project, but the issuer's overall cash flow, balance sheet, and long-term solvency.
But the underlying cash flow for data center financing usually comes from long-term leases. In the traditional cloud era, high-quality tenants, long-term rental periods, and stable demand are sufficient to support lower risk premiums. AI data centers are more capital-intensive, more power-intensive, and a single campus is more concentrated on a few large customers.
This will translate capital expenditure issues that technology stock investors are familiar with into credit market coverage issues. Moody's estimates that the six largest US hyperscale cloud vendors, Microsoft, Amazon, Meta, Alphabet, Oracle, and CoreWeave, will have related capital expenses of around $785 billion in 2026 and close to $1 trillion in 2027.
The larger the scale, the harder it is for the market to absorb new debt by “AI will grow” alone. JPMorgan research has estimated that data center securitization offerings could reach $30 billion to $40 billion per year in 2026 and 2027. This judgment is optimistic, but it also points to the same problem: after increasing circulation, buyers will demand more clear cash flow protection.
Previously, the market was willing to pay a growth premium for AI infrastructure, but now debt buyers are demanding credit discounts. For stock investors, the impact is not only on data center operators, but also on the free cash flow, profit margins, and capital expenditure pace of tech giants.
Private credit can be accepted, but the terms will be tougher
When the open market becomes picky, funding doesn't disappear right away, but instead shifts to more private, more customized channels. Private credit is becoming an important buffer for financing AI infrastructure.
This channel is appealing to borrowers. It can reduce price fluctuations and disclosure pressure in public offerings, and can also design structures that are more suited to asset cash flow for large-scale projects. For investors, the rewards come from higher yields, stronger collateral arrangements, and more detailed contractual protections.
But private funding is not an unconditional backbone. Its entry method is usually a redistribution of bargaining power. The length of the lease, the quality of tenants, asset collateral, refinancing arrangements, and electricity costs will all become terms of negotiation.
Banks and private capital can prevent short-term fluctuations in the open market from directly blocking construction. The risk is that financing transparency has declined, and it is more difficult for external investors to continuously observe real leverage and project cash flow pressure.
The channel switch itself is not a sign of crisis. It shows that open market discipline is taking effect: AI infrastructure can also borrow money, but it's getting harder and harder to borrow cheap, easy, and low-disclosure money. For issuers like Alphabet, the open market can still provide sufficient demand; for more project-based borrowers, the open market threshold is being raised.
Marginal projects bear cost pressure first
The first impact of this round of revaluation is not necessarily the tech giants with the strongest balance sheets, but data center operators, developers, and marginal projects that rely on continuous financing to expand on a rolling basis.
The popularity of Alphabet bonds reinforces this differentiation: the market is not unwilling to fund AI infrastructure, but is more willing to hand over money to those with the strongest credit qualifications and the most financing options. The closer to the project level, the more reliant on assets covered by future rents to cover debts, the more it is necessary to prove the quality of cash flow.
If the cost of financing a single transaction only rises slightly, it doesn't seem drastic. But in a capital expenditure cycle of tens of billions or hundreds of billions of dollars, changes within a few dozen basis points can also change project returns and affect the scale banks, insurance funds, and private credit are willing to undertake.
The core contradiction of AI infrastructure is shifting from “whether there is demand” to “whether demand can be met with sufficiently high cash flow.” As soon as there is a mismatch between lease pricing, speed of listing, electricity costs, and debt costs, marginal projects will first be repriced.
For large technology companies, the impact is more biased at the valuation level. The market has accepted that they are investing huge capital expenses for AI, but if financing costs, leasing commitments, and electricity costs go up together, investors will demand a more clear path to revenue return.
For data center REITs and operators, tenant quality is still a moat, but valuations will rely more on financing capacity. Assets that can obtain long-term, low-cost capital and secure high-quality leases will open the gap between assets that rely on short-term debt and have higher project uncertainty.
Earnings reimbursement determines the extent of debt revaluation
Current evidence is insufficient to support the judgment of an “AI debt crisis.” Alphabet bonds attracted subscription demand of about 115 billion US dollars. Pure DC turned to bank financing, and some data center debts can still be issued after increasing yields. All indicate that capital is still entering, but the prices and conditions for different entities to take money are clearly diverging.
The stress tests are yet to come. Financing costs need to remain manageable, long-term lease cash flow needs to be stable, and AI revenue will gradually be realized over the next few fiscal years. If these lines can be connected, the current widening interest rate spread is more like normalization after high supply.
Conversely, if revenue is realized more slowly than capital expenditure and electricity and debt costs continue to rise, the market will continue to raise risk pricing on AI infrastructure. For investors, AI demand is still important, but whether cheap money can continue to be supplied is becoming the second main valuation line in this AI infrastructure cycle.
