Revenue, EPS, operating income, and AI capital expenditure for the six largest tech companies — updated each earnings cycle.
| Company | TTM Revenue | YoY Growth | Operating Margin | AI Capex (2025 est.) |
|---|---|---|---|---|
| Apple (AAPL) | ~$391B | ~4% | ~31% | ~$10B |
| Microsoft (MSFT) | ~$245B | ~15% | ~44% | ~$80B |
| Alphabet/Google (GOOGL) | ~$350B | ~12% | ~32% | ~$75B |
| Amazon (AMZN) | ~$620B | ~11% | ~11% | ~$100B+ |
| Meta (META) | ~$164B | ~19% | ~42% | ~$65B |
| NVIDIA (NVDA) | ~$130B | ~122% | ~62% | ~$3B (R&D) |
AWS, Azure, and Google Cloud are the primary growth engines for Amazon, Microsoft, and Alphabet. AI workloads are now the fastest-growing segment within all three. Azure AI revenue grew 50%+ YoY in recent quarters; AWS AI services are scaling rapidly on top of a $100B+ infrastructure investment.
Meta and Google are the dominant digital ad platforms. Both are benefiting from AI-powered ad targeting improvements that are increasing advertiser ROI and CPMs. Meta's Advantage+ AI ad system has driven significant revenue acceleration. Google Search remains resilient despite AI search concerns.
The combined AI capex of the six biggest tech companies in 2025 exceeds $300B — an unprecedented concentration of capital. NVIDIA is the primary beneficiary. Microsoft is spending ~$80B, Amazon ~$100B+, Google ~$75B, Meta ~$65B. This capex cycle is the primary driver of NVIDIA's 122%+ revenue growth.
Apple is the slowest-growing of the six (~4% YoY) due to iPhone market saturation and limited AI product launches. Apple Intelligence is in early stages. Services (App Store, iCloud, Apple Pay) is the growth engine at ~$100B run rate. The company remains the most profitable business in history by absolute dollar terms.
The major tech companies report earnings quarterly, typically 3–5 weeks after their fiscal quarter ends. Apple, Microsoft, Alphabet, Meta, and Amazon report on roughly the same schedule (calendar Q1 ends in March, Q2 in June, etc.). NVIDIA reports on a February-April-July-October schedule. Earnings dates are announced 2–3 weeks in advance and are widely covered.
As of 2025 trailing twelve months: Amazon ~$620B (largest), Apple ~$391B, Alphabet ~$350B, Microsoft ~$245B, Meta ~$164B, and NVIDIA ~$130B (fastest growing at 122% YoY). Amazon's total includes both AWS and its massive e-commerce business. NVIDIA's explosive growth is almost entirely AI GPU-driven.
Combined AI-related capital expenditure from Microsoft, Alphabet, Amazon, and Meta is expected to exceed $300B in 2025. Amazon leads with $100B+, Microsoft commits ~$80B, Alphabet ~$75B, and Meta ~$65B. This unprecedented capex cycle is funding data centers, custom silicon, and AI infrastructure — with NVIDIA capturing the majority of hardware revenue.
