The way AI gets funded is changing, and the shift is happening quietly in a corner of finance most people never think about: the private bond market.
Tech companies are increasingly selling debt directly to insurance firms and large asset managers through private placements, skipping the traditional public bond market entirely. Private deals offer customized terms, longer maturities, and potentially higher yields, a combination that works for both sides of the table.
The numbers behind the pivot
By late October 2025, AI-related public investment-grade corporate debt issuance had reached $95 billion. Private placements added another $83 billion on top of that. Combined, that’s $178 billion in debt financing tied to AI infrastructure in a single year.
Meta alone raised roughly $29 billion through the private investment-grade market for data center investments.
