Founders Fund, a firm known for its concentrated "monopoly thesis," has invested in three competing AI labs: OpenAI, xAI (via SpaceX), and Anthropic. This deviation from their typical strategy suggests a belief that the AI market will evolve into a differentiated oligopoly with multiple winners, rather than a single winner-take-all monopoly.

Data reveals an extreme power law where model labs OpenAI and Anthropic capture nearly all AI startup revenue, and their share is growing. This indicates value is accruing to the foundational layer, posing an existential threat to the long-term viability of application-focused startups.

Comparing today's AI competition to the cloud market circa 2010 suggests we'll see multiple massive winners. Just as AWS's early lead didn't prevent Azure and GCP from becoming hundred-billion-dollar businesses, the AI market is vast enough to support several dominant labs like OpenAI and Anthropic.

Top AI labs like OpenAI and Anthropic engage in a 'Cournot Equilibrium' by competing on the supply of compute and data centers, not by undercutting each other on price. This strategy aims to create high barriers to entry and maintain high prices for access to frontier models.

The field of top US AI model developers—Google, Anthropic, OpenAI, Meta, and xAI—appears to be shrinking. Reports of Meta's model struggles and Elon Musk's public dissatisfaction with xAI's progress suggest the two companies are falling behind, potentially leaving a consolidated field of just three top contenders.

Despite massive investment, the race to build advanced AI models is narrowing to just three serious US competitors: OpenAI, Anthropic, and Google. Competitors like Meta and Elon Musk's xAI are falling behind due to internal chaos and strategic resets, concentrating power among a few key players.

Despite a booming AI startup ecosystem, revenue is intensely concentrated. Foundational model providers OpenAI and Anthropic capture nearly 90% of the market, and their share is growing, squeezing out application-layer companies.

The current oligopolistic 'Cournot' state of AI labs will eventually shift to 'Bertrand' competition, where labs compete more on price. This happens once the frontier commoditizes and models become 'good enough,' leading to a market structure similar to today's cloud providers like AWS and GCP.

The current AI landscape mirrors the historic Windows-Intel duopoly. OpenAI is the new Microsoft, controlling the user-facing software layer, while NVIDIA acts as the new Intel, dominating essential chip infrastructure. This parallel suggests a long-term power concentration is forming.
