How NVIDIA took the top spot

Apple held the title of world's most valuable company for most of the period between 2010 and mid-2024. NVIDIA passed Apple in June 2024, then crossed $4 trillion in July 2025 and $5 trillion in early 2026, lifted by demand for its Blackwell AI accelerators. For the full story, see our reference on NVIDIA's market cap.

Bigger than entire economies

NVIDIA alone is now larger than the gross domestic product of Germany, the United Kingdom, France or India. The combined market cap of the top three, NVIDIA plus Alphabet plus Apple, exceeds the GDP of every country other than the United States and China. Walmart became the first retailer to join the club in October 2025.
