This chart ranks major Fortune Global 500 companies by the steepest percentage drop in market capitalization between the end of 2020 and mid‑2025, using USD‑denominated data from MarketCapWatch. Only publicly listed companies were included; state‑owned enterprises, private firms, and entities with frozen or unreliable market caps were excluded.

Key takeaway: Some of the world’s largest revenue‑generating companies have seen their market value collapse by 25%–95% in just three years. The steepest declines are concentrated in China’s real estate and internet sectors, U.S. retail and telecom, and select European industrials — reflecting a mix of sector‑specific headwinds, regulatory shifts, and macroeconomic pressures.
