Despite fears that cheaper, open-source models would commoditize the market, the opposite is happening. While token usage for cheaper models is rising, the actual share of economic value (wallet share) is increasingly flowing to expensive frontier labs like Anthropic and OpenAI.

OpenAI and Anthropic form a powerful duopoly at the "frontier" of AI, commanding premium prices like Apple. A second, commoditized tier of open-source and lagging models exists, where value is captured through compute and services, not the model itself. This creates a clear market separation between premium and "good enough" AI.

The AI market will bifurcate. Open models will dominate most commodity tasks. However, the most economically significant problems—like advanced scientific research—will rely on closed, frontier models, allowing them to capture a disproportionate share (30-40%) of the total economic value.

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.

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 market for AI models is bifurcating. Users either pay a premium for top-tier frontier models for high-stakes tasks like cybersecurity or use extremely cheap, small models for high-volume, simple tasks. Mid-tier models struggle to find a viable use case, getting squeezed from both ends.

Analyst Gavin Baker argues a few dominant AI labs create a monopsony (a dominant buyer) for compute, suppressing margins for everyone else. The rise of competitive open-source models decentralizes this power, shifting value back to other layers of the AI stack, from chips to software and cloud providers.

The AI market will likely split along the lines of the smartphone industry. Closed, frontier models (OpenAI, Anthropic) will be like iOS—premium, high-margin, and dominant in the US. Open-source models will act as Android, capturing the vast majority of global users through lower costs and greater flexibility.
