Simple Definition

Money a company spends on long-term physical or strategic assets — factories, equipment, data centers, GPUs — rather than on day-to-day operating expenses. Capex shows up on the cash flow statement, not the income statement.

Why It Matters

Capex is how a company invests in its own future. The 2026 AI boom is essentially a story about hyperscaler capex: Microsoft, Google, Amazon, and Meta are collectively spending over $700 billion building AI infrastructure. Whether that spend pays off — and how fast — is the central debate driving every AI stock.

Key Points

  • Capex is investment in long-term assets; OpEx is the cost of running the business day-to-day.
  • Capex-heavy industries (cloud computing, semis, telecoms, utilities) trade differently than capex-light ones (software, services).
  • When capex grows faster than revenue, free cash flow temporarily falls — bears watch this ratio closely in AI infrastructure debates.
