Top 20 Companies by Market Cap
The world's 20 most valuable listed companies ranked by US-dollar market capitalisation, spanning semiconductors, cloud computing, energy, pharmaceuticals, retail, and banking. Figures are a close-of-market snapshot from the end of May 2026, reflecting what investors will pay today for each company's expected future cash flows rather than its current revenue.
Interesting Facts & Summary
Eight of the top 20 are semiconductor companies — NVIDIA, TSMC, Broadcom, Samsung, SK hynix, Micron, AMD, and ASML — covering nearly every link of the AI compute chain from chip design and foundry to memory and lithography. Memory tells the story best: SK hynix and Micron are both now worth over $1 trillion, yet at the end of March 2026, just two months earlier, they ranked only 25th and 29th in the world.
For a sense of scale, the top five companies are together worth about $20.5 trillion, roughly China's entire annual GDP (about $20.9 trillion). Walmart, the world's largest company by revenue, sits only 16th here — market value and revenue have never measured the same thing.
