Who are the big 7 AI companies?

The "Big 7" companies dominating the artificial intelligence landscape—often aligned with the financial markets' "Magnificent Seven"—are NVIDIA, Microsoft, Alphabet (Google), Amazon, Meta, Apple, and Tesla. NVIDIA supplies the underlying computational hardware; Microsoft and Amazon provide global cloud infrastructure and commercial deployment platforms; Alphabet and Meta drive pioneering open-source and proprietary research models; Apple brings applied on-device AI to a global base of billions of personal devices; and Tesla develops real-world vision models, autonomous robotics, and edge compute for transportation. Together, these seven multinational giants fund the vast majority of private AI research, compute infrastructure, talent acquisition, and commercial deployments across the globe.
