One point does not establish a trend. Company-size values are not provided by these model-provider disclosures.
Delivery route: not established
The records name providers, but do not establish direct API use versus Azure OpenAI, Bedrock, or Vertex. All 8 records remain unclassified by delivery route; no route split is inferred.
Public-source observations. Observation dates are review dates, not adoption dates.
The numerator is the distinct companies naming a provider. The denominator is the distinct companies naming any included model provider in the selected sample. A company can appear in more than one numerator, so shares may total more than 100%.
OpenAI and Anthropic market share
This is an observed-coverage comparison, not a total-market estimate. The small sample was selected for public evidence and is not representative of enterprises as a whole. It does not measure revenue, token volume, seats, or model requests.
Direct vs. indirect deployment
Naming a provider in a disclosure does not prove whether requests use a direct API or a cloud intermediary. We keep unknown delivery routes separate and do not assign Azure OpenAI, Bedrock, or Vertex usage from a generic cloud-provider relationship.
Embedding and monthly updates
The embeddable image carries its review date and denominator. It changes when a new reviewed snapshot is published. The current monthly series has one point; no smooth adoption curve or historical share is inferred.
A public job board supports an ATS observation. A subprocessor disclosure identifies a provider that may process data for particular services. A vendor customer story describes a published relationship. These sources have different scopes and are labeled separately.
Counts cover the records on these pages, not the whole market. No observation in our covered sources does not mean a company does not use a vendor. Source recency and unresolved conflicts affect confidence; observations do not establish spend, renewal timing, or customer churn.
