Fed Survey Names AI the Top Threat to the U.S. Financial System as Data Center Debt Passes $680 Billion
Artificial intelligence has become the single biggest worry among the Wall Street professionals the Federal Reserve asks about threats to the U.S. financial system, according to the central bank’s latest Financial Stability Report, released on Friday, November 13.
Eighty-seven percent of the market contacts surveyed named AI a salient risk to financial stability — up from just 50 percent in the Fed’s spring survey. No other risk came close.
A sharp rise in six months
The survey, run by staff at the Federal Reserve Bank of New York, drew responses from 23 contacts at broker-dealers, banks, investment funds and advisory firms in September and October. The Fed stresses that the results summarize the respondents’ views, not the views of its board or the New York Fed.
The next most-cited risks were a broad correction in risk assets, named by 52 percent of contacts, followed by higher long-term interest rates at 48 percent, cyberattacks at 43 percent and fiscal debt sustainability at 43 percent.
Respondents described three separate AI worries: elevated stock valuations and the possibility that lower-than-expected earnings could trigger a market correction; cybersecurity risk, including attacks by sophisticated state actors and damage caused by frontier AI models themselves; and risks tied to complex forms of AI-related financing.
The warning landed in a jittery market: Wall Street ended mixed Friday as chip stocks slid again, though the Nasdaq still posted its best week since August.
The debt behind the data center boom
The report goes beyond the survey. In a section on leverage in the data center buildout, Fed staff lay out how quickly borrowing for AI infrastructure has grown — and how much of the industry’s exposure sits off balance sheets in leases, guarantees and contracts.
Debt issuance tied to advanced computing infrastructure has surged to more than $680 billion by October 2026, about five times the $130 billion issued in all of 2023. AI-related borrowing now accounts for nearly a third of all nonfinancial investment-grade corporate debt issuance, up from less than 6 percent three years ago. Outstanding public debt related to advanced computing is estimated at more than $1.1 trillion.
The total picture is larger still. Reuters summarized the Fed’s figures as debt, guarantees and not-yet-commenced leases that could exceed $3 trillion. For seven companies — Amazon, Alphabet, Broadcom, Meta Platforms, Microsoft, Nvidia and Oracle — the Fed tallies leases signed but not yet started at more than $1 trillion in undiscounted value, plus other commitments such as take-or-pay contracts and residual value guarantees above $2 trillion.
The largest U.S. bank holding companies have close to $1 trillion of exposure to large technology firms, data center developers, related special purpose vehicles and private credit funds, and utilities. Those exposures are covered in the annual stress test.
A comparison to the telecom boom
Fed staff compare the cycle with the broadband telecom investment boom of the late 1990s. Measured against GDP, the cumulative capital spending of five hyperscalers — Amazon, Alphabet, Meta Platforms, Microsoft and Oracle — since 2020 has tracked the telecom industry’s closely, but the report says AI investment has been accelerating and “may surpass that of the 1990s telecom cycle relatively soon.”
The report focuses on the complex financing arrangements underpinning the buildout. Long-term contracts, leases and guarantees let hyperscalers and other large firms support financing of projects by smaller third parties, while graphics card designers and hyperscalers often contribute through equity stakes.
The Fed calls this “circular financing.” It could allow the largest firms to absorb losses in a downturn, shielding the wider system — but it could also mean their real exposure “may be substantially larger than suggested by their on-balance-sheet liabilities.”
“The complex interlinkages among firms engaged in the data center buildout, public credit markets, private lenders, and special purpose financing vehicles create vulnerabilities that necessitate close monitoring,” the report stated.

Why this matters
The report is not a forecast, and a survey of 23 market contacts measures sentiment, not proof of danger. But it puts the central bank’s own numbers on how the AI boom is being financed — including the large share of commitments that conventional debt measures miss.
The Fed also noted that asset valuations across a range of classes remain high, due in part to investor enthusiasm about AI, and that investment in the sector has been a significant driver of U.S. economic growth this year. An unexpected downturn in corporate earnings could prompt a market decline, tighter credit and reduced investment, which would all weigh on the economy.
The Fed’s concern about valuations comes as inflation data stays hot: wholesale prices rose 0.3% in October, pushing annual inflation to 6.5%.
Elsewhere, the report’s picture is steadier. It describes the banking sector as “sound and resilient overall,” with capital near historically high levels, and household debt relative to GDP continued to fall. The sore spot is leverage at hedge funds, which reached the highest level since the Fed began gathering such data in 2013 and is concentrated in a small number of large funds.
Latest developments
The timing of the survey matters. It closed before Jensen Huang resigned as Nvidia chief executive on November 12, and before this month’s midterm elections, in which public concern about AI was a central issue. The latest chapter of the Nvidia story is covered in our report on how Musk warns Nvidia could lose ‘critical’ deals without Huang.
CNBC reported that the report covers data through October 28, and cited exit polling in which 56 percent of midterm voters called data centers of crucial or major importance to their choices.
Frequently Asked Questions
What did the Fed survey find about AI?
In the Federal Reserve’s November 2026 Financial Stability Report, 87 percent of the 23 market contacts surveyed named artificial intelligence a salient risk to U.S. financial stability, up from 50 percent in the spring survey. It was the most-cited risk by a wide margin.
How much debt is behind the AI data center boom?
Debt issuance tied to advanced computing infrastructure reached more than $680 billion by October 2026, about five times the $130 billion issued in all of 2023. Including guarantees and leases not yet started, the Fed’s figures point to total commitments that could exceed $3 trillion.
Does the Fed think an AI bubble will burst?
No. The Financial Stability Report is not a forecast, and the survey measures the views of market contacts, not the Fed’s own position. The report warns that elevated valuations and complex financing create vulnerabilities that need close monitoring.
Which companies are most exposed?
The report names five hyperscalers — Amazon, Alphabet, Meta Platforms, Microsoft and Oracle — and tallies large off-balance-sheet commitments for seven companies, adding Broadcom and Nvidia. Large U.S. banks have close to $1 trillion of exposure to tech firms, data center developers and related financing vehicles.
The Fed’s message is clear: the central bank is now watching the same concentration of risk that has made AI stocks dominate the markets — and the borrowing behind it is far larger than the headline debt figures suggest. What happens next depends on whether AI earnings keep pace with the spending.
