Who makes capital & financing for AI data centers

Data center construction and the compute inside it are increasingly financed through purpose-built capital structures — infrastructure funds, private credit, project finance from banks, and lending secured against GPU fleets rather than real estate. This chain does not supply a physical part; it supplies the capital that lets developers and operators buy the parts described in every other layer, from HV switchgear to the compute silicon itself. Because so much AI infrastructure spending now runs through debt and structured finance rather than corporate balance sheets, the health and terms of this financing chain influence how fast capacity can be built out. For investors, exposure here is indirect: through asset managers, banks, and business development companies rather than through any single physical product.
