The ten brands on this page account for about US$10.6 trillion of combined value — market capitalisation for the listed names, latest disclosed private marks for the rest — and roughly US$2.4 trillion of trailing revenue. Two of them are still private and worth more than almost every public software company: OpenAI at a reported US$852 billion, Anthropic near US$1 trillion. The layer they occupy is not the model itself. It is the decision of which model an enterprise is allowed to use, and that decision now sits with fewer vendors than any category in enterprise software since the mainframe.
We rank these brands on four dimensions, and the weights are deliberately not equal. Model capability and research velocity carry 30 percent: measured through independent evaluations, shipped product cadence and how quickly a gap opens or closes. Platform and distribution carry 25 percent, because a frontier model with no distribution is a research lab, not a brand. Commercial traction and unit economics carry 25 percent — disclosed revenue where it exists, contract structure and gross margin where it does not. Ecosystem and data position carry the final 20 percent: developer mindshare, data gravity, and whether customers build on top of the platform or merely rent it. Those four produce a Composite Score on a 0 to 100 scale.
The spread between first and tenth is roughly two orders of magnitude — US$4.1 trillion for Google's parent against about US$10 billion for SenseTime. What separates them is not model quality. It is whether the brand owns a distribution channel that survives the commoditisation of the model layer. Microsoft and Google sell AI through infrastructure their customers already rent. OpenAI and Anthropic sell tokens and seats directly, which is higher margin and far more fragile. Palantir, Databricks and Snowflake sell the data and decision layer beneath AI, where switching costs are measured in years. Baidu, iFLYTEK and SenseTime monetise applied deployment inside China, where compute constraints and domestic data rules produce a different, slower, but defensible business.
Methodology note: private valuations are the latest disclosed marks as of October 2026, converted at period-end exchange rates; unaudited figures are marked. Revenue refers to the most recent full fiscal year unless a company reports annualised quarterly run-rate, which we label as such.
