In the early parts of the AI capex buildout, financing came primarily from the free cash flow generated by hyperscalers. Recently, that narrative has started to shift, with high-profile debt and equity raises coming from Google, Oracle and other major hyperscalers in 2025 and 2026, primarily to fund data center buildout.
Dubravko Lakos-Bujas, head of Global Markets Strategy at J.P. Morgan, believes investor appetite to fund AI capex is far from exhausted. “The high-grade market still has substantial capacity to absorb future issuance, although spreads may continue to adjust as supply expectations evolve,” said Lakos-Bujas. “Funding sources are also beginning to broaden towards equity, with Alphabet raising $85 billion in equity in June 2026 and recent (media) reports indicating that Meta is evaluating similar alternatives.”
Importantly, the increase in external financing is not believed to be weakening the operating fundamentals of hyperscalers, for which operating cash flow is still expected to exceed $900 billion by 2027. “In effect, the Street appears to be underwriting the AI data center monetization case: elevated capex today should ultimately translate into higher revenue, stronger margins and expanding cash flow,” said Lakos-Bujas.
