4 "Magnificent Seven" Companies Are About to Report Earnings -- All on the Same Day. Here's What to Watch.

Earnings from four mega-cap tech firms (Alphabet, Amazon, Microsoft, Meta) due after the close could drive significant market volatility given their combined market caps and massive AI-related capital spending. Collectively, their 2026 capital-expenditure plans could top $600 billion, raising depreciation and pressure on operating income. Investors will watch revenue growth — the crucial read-through for whether AI investments are translating to top-line gains — and operating-income trends as rising CapEx flows into depreciation. Company data cited: Alphabet grew revenue 18% (Google Cloud +48%, $17.7B) and plans $175–185B in CapEx; Microsoft posted 17% revenue growth with Azure up 39%; Meta’s Q1 guidance midpoint implies ~30% y/y revenue growth; Amazon’s Q4 revenue was $213.4B with AWS up 24% to $35.6B and guidance implying 11–15% Q1 growth. Given the stakes and scale of spending, the reports could meaningfully move the broader market and individual mega-cap stocks.
