Amazon's Q2 Capex Exceeds AWS Revenue, Pressuring Free Cash Flow but Not Breaking the Long-Term AI Thesis

What happened

Amazon reported Q2 2026 capital spending of about $53 billion, exceeding AWS revenue of $42 billion, intensifying investor scrutiny over the AI infrastructure buildout. This spending surge contributed to trailing twelve-month free cash flow of negative $7.6 billion, even as AWS grew 37% year over year and generated $16.6 billion in operating income. Management maintains that customer commitments, including more than $100 billion each from OpenAI and Anthropic, back a substantial portion of the spending, with monetization expected in 2027-2028. However, the immediate cash burn raises the stakes for AWS to sustain elevated growth and margin expansion to justify the outlay. The news aligns with our existing assessment that Amazon is in a heavy investment phase where near-term returns are back-end loaded.

Implication

The capex figure includes spending across all segments, not just AWS, so a direct comparison with AWS revenue is imperfect. Amazon's balance sheet remains strong with $123 billion in cash and securities, net debt to EBITDA of 0.4x, and interest coverage of 28x, providing ample runway for the buildout. The real risk is if depreciation and infrastructure costs outpace monetized AI demand, which would compress margins and extend negative free cash flow. Our base case assumes AWS growth holds near 28-32% and free cash flow remains modestly negative into mid-2027; a break below 25% AWS growth with rising costs would shift us to a bear case with fair value near $220. Monitor quarterly AWS operating income and the persistence of large customer commitments; if those weaken, the pre-sold capacity thesis cracks and the stock likely reprices lower.

Thesis delta

The news does not alter our WAIT rating; it reinforces the existing tension between high capex and delayed payback. The capex-to-AWS-revenue comparison is attention-grabbing but not a standalone red flag because capex serves the entire company and is partially pre-funded by contracts. Our conviction remains that Amazon's stock already prices in sustained AWS acceleration, so we maintain the WAIT with an attractive entry near $235.
