Tech giants issued $159 billion in bonds in five months to fund AI. The Bank of England is watching. Here is what it means for ordinary investors.
I have a friend who renovated a kitchen on a bridging loan.
The kitchen was beautiful. Genuinely, properly beautiful, the sort of room that makes you want to cook things you have no idea how to cook. The problem was never the kitchen. The problem was that the loan assumed a house sale would complete by a particular month, and houses, as anyone who has sold one will tell you, have opinions about your timetable that they decline to share in advance.
She was fine in the end. But I have thought about that kitchen a great deal this month, because the largest companies in the world are currently doing something structurally similar; at a scale that has caught the attention of central banks.
The Number That Changed the Conversation
The Bank of England’s July Financial Stability Report noted that AI companies are increasingly turning to the financial system for external financing, particularly debt financing, to fund infrastructure investment, and that this has accelerated sharply in the first half of 2026.
The scale is worth sitting with. Analysis from Dealogic found that the major AI infrastructure builders, Amazon, Alphabet, Meta, Microsoft and Oracle, issued around $159 billion in corporate bonds in the first five months of 2026 alone. That figure exceeds their combined borrowing over the previous five years. Nvidia issued $25 billion in bonds, its first round since 2021.
None of this happened because these companies ran out of money. They are among the most cash-generative businesses in history. It happened because they made a choice.
Why Borrow When You Are Sitting on Cash
The choice is a sensible one on its own terms. Borrowing lets a company build faster than its cash flow alone would allow, preserve its cash cushion, and spread the cost of a very large project across a longer period. Any business owner would recognise the logic. It is the same reason you might take a mortgage rather than wait to buy a house outright.
Borrowing unavoidably transfers risk. When a project is funded from profits, the company carries the outcome alone. When it is funded from credit markets, the outcome becomes something a much wider group of people are exposed to, including pension funds, bond funds, insurance companies, and, at several removes, you.
The Part Nobody Is Advertising
Here is the detail I find most worth understanding. A growing share of this financing is not happening in the public bond market at all. It is happening through private credit funds and off-balance-sheet structures, arrangements that do not show up in the accounts in the way a straightforward corporate bond does.
The consequence is not that anything improper is occurring. The consequence is that it becomes harder to see who is actually holding the risk. Public balance sheets stop telling you the whole story. If the returns on all this infrastructure arrive later than the financing assumed, the losses will land somewhere, and working out where in advance is now genuinely difficult.
I wrote recently about private credit coming under strain for the first time at scale, and this is the other end of that same pipe. The money going into AI infrastructure and the money coming out of private credit funds are frequently the same money.
How I Am Reading It
I want to be careful here, because there is a lazy version of this argument that says: AI is a bubble and everyone should panic. I do not think that is right, but I also have no idea if it is right.
The question is not whether AI works. The question is one of timing. Debt has a schedule. Interest payments arrive on the date agreed, regardless of whether the thing the money built has started earning yet. A project funded from profits can be patient. A project funded from credit cannot.
So what I watch is not the AI headlines. It is the credit market. When bond investors start asking for more yield to lend to these companies, they are telling you their confidence in the timetable has shifted, and they usually notice before the rest of us do. Coverage on hyperscaler bond issues has already been slipping this year, which is not a crisis, but it is a signal worth reading.
The kitchen was always going to be beautiful. The only question was whether the house sold on time.
