Big Tech Earnings: The AI Capex Reckoning

Alphabet and Tesla released second-quarter 2026 results on July 22, and AMD reported on August 4. The results are now available, so the useful question is no longer what the companies might report. It is what their filings actually show about cloud and data-center demand, operating margins, and the cost of pursuing AI-led growth.

Alphabet: cloud growth and a separate investment gain

Alphabet reported Q2 2026 revenue of $119.8 billion, up 24% year over year. Google Cloud revenue rose 82% to $24.8 billion. Alphabet’s operating income increased 30%, and its operating margin expanded two percentage points to 34%.

The filing also reported a $98.0 billion net gain in other income, primarily from unrealized gains on equity securities. That gain is economically different from cloud revenue and operating income. Separating the two avoids treating an investment mark-up as evidence of operating return on AI infrastructure.

For historical context, Alphabet’s 2023 Form 10-K says capital expenditures were $31.5 billion in 2022 and $32.3 billion in 2023—an increase of about 2.5%, not 91%. The Q2 2026 cloud result shows strong demand, but a complete return-on-capital assessment still requires the timing and useful life of infrastructure investment, depreciation, margins, and future cash flows.

Tesla: volume, revenue, and margin

Tesla reported 480,126 vehicle deliveries in Q2 2026. Its quarterly filing reported $28.24 billion in revenue, up $5.74 billion from the year-earlier quarter, while net income attributable to common stockholders declined by $58 million to $1.11 billion.

Total automotive gross margin moved from 17.2% to 16.9% year over year. Research and development expense rose 49% to $2.37 billion. Together, those figures show why volume growth, current profitability, and investment in autonomous-driving and robotics programs must be evaluated separately rather than compressed into a single “AI winner” verdict.

AMD: data-center demand

AMD reported Q2 2026 revenue of $11.5 billion, up 50% year over year. Data Center revenue was $6.7 billion, up 107%; GAAP gross margin was 54%; and GAAP operating income was $2.0 billion.

Those results are direct evidence of strong current demand for AMD’s data-center products. They do not, on their own, settle how industry capacity, competitive pricing, customer concentration, or future product cycles will affect returns. That requires following segment revenue, segment operating income, inventory, guidance, and customer deployment over multiple periods.

What the results say—and what they do not

The three reports show that AI-related cloud and data-center demand can coexist with very different economic questions. Alphabet paired rapid cloud growth with a large non-operating investment gain. Tesla grew revenue and deliveries while automotive margin and R&D moved in opposite directions. AMD produced strong data-center revenue and operating growth.

None of those quarterly observations is a complete calculation of return on AI capital spending. A defensible assessment should keep operating performance separate from unrealized investment gains, compare like-for-like periods, and track cash investment against the later revenue and margins attributable to that investment.

Correction — August 25, 2026: An earlier version retained pre-earnings language after the results were available, included unsupported market forecasts and valuation claims, and misstated Alphabet’s historical capital-expenditure growth. The article has been replaced with a primary-source, post-results analysis. Alphabet’s reported capital expenditures increased from $31.5 billion in 2022 to $32.3 billion in 2023, or about 2.5%.
