Largest Public Company by Market Cap in Each High‑Income Economy

This chart ranks the most valuable publicly listed company headquartered in every economy classified as high‑income by the World Bank (GNI per capita ≥ USD 13,845, Atlas method). Market caps are in USD billions, based on closing prices as of Aug 29, 2025.

Takeaway: A handful of mega‑caps dominate the landscape — NVIDIA (US, $4.38 T) and Saudi Aramco (Saudi Arabia, $1.53 T) tower over the rest, with Samsung (South Korea, $327 B) leading Asia’s hardware sector. Europe’s leaders include SAP SE (Germany), LVMH (France), and ASML (Netherlands), each above $290 B.

Analysis:

• Sector concentration: Tech and energy giants hold the top spots, reflecting global demand for AI, semiconductors, and oil.
• Regional diversity: While North America and Europe dominate the upper ranks, Asia’s representation is strong, led by South Korea, Japan, and Singapore.
• Scale gap: After the top two, market caps drop sharply, highlighting the outsized influence of a few global players.
• Small‑economy standouts: Firms like AIA Group (Hong Kong SAR) and Xero (New Zealand) show that even smaller markets can produce regionally significant champions.
