The Bifurcation in the AI Market
Despite open-source AI models being 10-100x cheaper, proprietary providers haven’t lost pricing power. OpenRouter’s data reveals a market splitting in two.
Over the last year, open-source models’ market share has remained stable around 22-25%, briefly spiking to 35% during the explosive growth of Chinese models in mid-2025 before settling back down.
The weak price elasticity indicates that even drastic cost differences do not fully shift demand; proprietary providers retain pricing power for mission-critical applications, while open ecosystems absorb volume from cost-sensitive users.
