Tech Giants Fund AI Boom Differently - Cash, Debt, or Partnerships

Microsoft stands out as the only major tech company that still pays cash for its AI investments. Its operating cash flow of $55.4 billion in Q2 2026 covered its net capital expenses, leaving a substantial free cash flow of $19.6 billion. The company also spent $4.06 billion on share buybacks and increased dividend payouts by 9.5% to $6.76 billion.

In contrast, Alphabet is currently operating in the red, with negative free cash flow for the first time since its IPO in 2004. Despite holding a significant cash hoard of $126.8 billion at the end of Q1, Alphabet has had to take on debt and halt share buybacks to support its cash requirements.

Amazon is also relying heavily on debt to fund its AI investments, selling $25 billion in bonds this year alone. Meta Platforms, meanwhile, is splitting the cost with a partner by signing multi-year data center deals that pre-fund part of the infrastructure build.
