JPMorgan and Goldman Sachs are betting billions on European AI infrastructure debt
Wall Street's two biggest names are building dedicated teams to flood Europe's data-center market with capital, chasing a continent-sized gap in AI spending.
Europe’s AI buildout has a financing problem. Wall Street has noticed.
JPMorgan Chase and Goldman Sachs are preparing to underwrite billions of dollars in AI-related debt across Europe, with data centers as the primary target. Both banks have assembled dedicated teams to connect data-center operators with institutional investors, positioning themselves at the front of what Goldman estimates could become a $5B to $10B bond market by the end of 2026, with significantly higher volume expected in 2027.
To put that gap in perspective: AI-related debt currently makes up roughly 5% of high-yield issuance in Europe. In the US, that figure sits at 19%.
The size of the bet
The math on individual deals is striking. A single data center in the 100 to 200 megawatt range can support a debt package between $1B and $2B on its own.
Bloomberg Intelligence has put the continent’s total infrastructure need at around $3 trillion through 2035, covering cloud capacity, power, and data centers. Portugal’s planned Start Campus facility, a 1.2-gigawatt project, illustrates the scale of ambition involved.

Why now, and why these banks
JPMorgan and Goldman are not the first institutions to identify Europe’s AI infrastructure deficit, but they are among the first to formalize dedicated coverage teams around it.
The contrast with the US is instructive. American lenders have spent several years developing underwriting standards, deal structures, and investor education around AI infrastructure debt. AI-related high-yield issuance represents approximately 5% of the total in Europe, contrasting sharply with the 19% proportion in the US.
What the capital wave means for the market
For European data-center operators, the entry of JPMorgan and Goldman into this market as active underwriters signals access to a deeper pool of global fixed-income capital than European-focused banks alone can provide. Operators that previously relied on bank loans or private credit now have a credible path to public bond markets, which typically offer larger deal sizes and longer maturities.
With Goldman projecting a market inflection point in 2027, and Bloomberg Intelligence’s $3 trillion figure setting the outer boundary of what the continent needs to build, JPMorgan and Goldman are positioning to capture a disproportionate share of the fees and relationships that come with being first into a new market at scale.
