Who Can Afford the AI Buildout? Follow the Balance Sheets

The soaring cost and operational risk of building AI infrastructure—especially as companies race to deploy next-generation Nvidia chips—are driving a clear split in how the industry finances growth. Tech incumbents like Microsoft and Google are leaning on scale, credit strength and partnerships to spread risk, while challengers such as Anthropic and xAI are pursuing more concentrated, higher-leverage strategies to secure control over data centers, chips and power. The result is a widening gap in who absorbs risk, who controls infrastructure and who can sustain long-term investment as AI spending accelerates.

We asked Deep Research how these diverging financing models are reshaping competition—and what they reveal about the balance of power between incumbents and AI challengers in the infrastructure race.
