Key takeaways 

  • Globally, the largest artificial intelligence (AI) firms are based in the United States, China, Chinese Taipei, Korea and the Netherlands.
  • These global AI giants account for an increasing share of total market capitalisation, capital expenditure and revenues in their respective jurisdictions.
  • For many AI giants – and particularly those from the United States and China – scope and scale go together as they expand the breadth of their activities into multiple layers in the AI supply chain.
