AI Oligopoly: The Three-Horse Race
The consolidation of the foundational AI model layer from 60+ startups to an oligopoly of three dominant players: Anthropic (enterprise/code), OpenAI (consumer), and Google/Gemini (never to be counted out). This mirrors how the cloud market evolved — three companies underpinning the entire SaaS world.
Where it comes from
Alex Sacerdote, describing Whale Rock's thesis evolution from 2023 to 2025 as they watched the foundational model layer consolidate (highlights/alex-sacerdote-how-to-invest-through-technology-cycles). > “Two or three years ago, there were 60 different companies going after it. OpenAI was kind of in the lead... what we saw over the following 3 years was that almost all the startups fell away and died.” (~2:57)
The AI model layer is following the same oligopoly pattern as cloud (AWS/Azure/GCP) — not winner-take-all, not commodity, but a stable three-player market with differentiation that produces excellent businesses. The open-source risk is real but contained: “they can come close to the leading edge but they can't leapfrog it.”
