Two families dominate. Of the 2,135 employers worldwide whose job adverts name an AI tool, 62.1% name OpenAI's tools (ChatGPT, Codex or the OpenAI API) and 58.1% name Anthropic's (Claude or Claude Code). No other tool is named by more than a quarter of them.

The race is closer country by country. In the United States and Canada, employers now name Claude more often than OpenAI's tools; in the other countries with enough employers to measure, OpenAI is level or ahead.

By country

  1. India: Claude 49.7%, OpenAI 69.8% (288 employers naming a tool)
  2. United States: Claude 66.7%, OpenAI 63.4% (505 employers naming a tool)
  3. Canada: Claude 64.7%, OpenAI 57.8% (102 employers naming a tool)
  4. United Kingdom: Claude 52.9%, OpenAI 54.8% (155 employers naming a tool)

How we measured it

We read the job adverts on the careers sites of employers worldwide, hundreds of thousands of them, and recorded the AI tools and model families each advert names in the role's own text: the tools the role uses, the skills it asks for or the team's stack. Blog headlines, news sidebars, customer lists, rules for candidates and recruitment-process text do not count, nor do job boards, investor portfolio boards, recruitment agencies or the AI vendors' own sites. OpenAI includes ChatGPT, Codex and the OpenAI API; Anthropic includes Claude and Claude Code. An employer's country is given only where its pages clearly say where it is. The United Kingdom row comes from this worldwide sample; it is not the figure from our separate study of UK employers' own careers pages, which reads a different set of employers. We checked a sample of flagged adverts by hand. An employer counts once however many adverts name a tool.

Across countries, the same handful of AI tool names dominate job adverts. The exceptions — which country names which tool — are where the story is.
