The ten brands on this page carry about $13.7 trillion in market value and roughly $1.7 trillion in trailing revenue. Alphabet alone trades near $4.1 trillion on $445.9 billion of revenue, Amazon at $2.70 trillion on $742.8 billion, Microsoft at $3.93 trillion on $331.8 billion. No earlier industry page in this series starts from that scale, and none starts from a field this narrow: every entrant already owns the distribution layer its competitors rent.
What separates first from fourth is not reach but revenue purity. Alphabet draws more than 85% of its cash from search, YouTube and platform services; Meta draws almost all of its $228.2 billion from advertising across 3.5 billion daily users; Microsoft spreads $331.8 billion across Azure, Office and Windows, so only part of its book is platform revenue in the strict sense. Amazon books the largest top line here and finishes second because retail margins dilute a score that pays 30% for platform purity.
The four weights are fixed before any company is scored: 40% global revenue and brand equity, 30% purity of search, social, cloud, marketplace or streaming revenue, 20% owned infrastructure — data centres, subsea cables, self-designed silicon — and 10% user scale and search heat. ByteDance is scored on disclosed ranges rather than a share price, because it is private. Where two brands are within one point of each other, the tie breaks on infrastructure ownership, not on traffic.
