Summer of AI Financing

The summer of 2026 may ultimately be remembered not for a new model release

or a breakthrough chip, but for developments in AI financing that highlighted how

quickly capital markets are adapting to the demands of the AI buildout. In just a few

months, hyperscalers materially increased already ambitious capex plans, public and

private credit markets took on a larger role in funding AI infrastructure, investors

differentiated more sharply among borrowers and business models across the AI

financing ecosystem, and financing structures evolved rapidly, extending deeper into

the value chain and increasingly targeting individual components, particularly chips.

None of this was wholly unexpected. The scale of AI investment has long suggested

that traditional funding channels alone would prove insufficient. What has been

remarkable is the speed, breadth, and creativity with which markets have responded.

Yet beneath the headlines lie important lessons for investors as the next phase of

the AI investment cycle unfolds.

The starting point remains unchanged: demand for compute continues to outstrip

supply, resulting in upward revisions in AI infrastructure capex expectations as

hyperscalers commit additional capital to secure future capacity. Our equity

research colleagues now estimate that total capex for the four largest hyperscalers

(Microsoft, Alphabet, Amazon, and Meta) will rise 57% in 2027 versus 2026. These

spending plans reflect growing conviction that such investments can generate 25%+

returns on invested capital (see Morgan Stanley Internet analyst Brian Nowak's

report, 'The Paths to 25-50% GenAI ROIC'). At the same time, the lag between capex

deployment and monetization continues to pressure near-term cash generation,

with our analysts' 2027 free cash flow estimates for the four hyperscalers

continuing to move lower. The result is a widening financing gap in 2027, reinforcing
