#8 Broadcom

Number 8 in our top 10 companies by market cap in 2026 is the giant most people have never knowingly used – yet touch constantly. Broadcom makes the networking chips, connectivity components and infrastructure software that quietly run data centers, smartphones and broadband worldwide. Its rise into the trillion-dollar club is powered by the same force lifting the whole list: AI. Hyperscalers now hire Broadcom to design custom chips for their data centers, making it one of the biggest winners of the AI infrastructure boom after Nvidia itself.

Key facts

  • Market cap: ~$1.6-1.9 trillion (approximate – confirm on publish day)
  • Sector: Semiconductors and infrastructure software
  • Founded: Roots to 1961 (as HP's semiconductor division); modern Broadcom via merger
  • Why it matters: The custom-chip partner behind much of the AI data-center buildout

Why it ranks here

  • It's a prime beneficiary of AI data-center spending, second only to Nvidia in chips.
  • Custom silicon for hyperscalers gives it deep, sticky customer relationships.
  • Its software arm (including VMware) adds recurring revenue on top of chips.
