State of Open Source on Hugging Face: Spring 2026
China now surpasses the US in monthly AI model downloads, capturing 41% of Hugging Face's traffic.
Hugging Face's Spring 2026 State of Open Source report reveals an ecosystem that has nearly doubled in size, now boasting 11 million users, over 2 million public models, and 500,000 public datasets. This growth signifies a shift from passive consumption to active creation, with users increasingly building fine-tuned models, adapters, and applications. However, the landscape is highly concentrated: the top 200 models (just 0.01% of the total) account for 49.6% of all downloads, while half of all models have fewer than 200 downloads. The report frames open-source AI not as a single market but as a collection of specialized, overlapping sub-ecosystems where communities form around specific domains and languages.
A major geographic power shift is underway. Data shows China has surpassed the United States in both monthly and overall model downloads on the Hugging Face Hub, now accounting for 41% of all downloads. This marks a fundamental change from historical patterns where the US and China were top contributors, followed by the UK, Germany, and France. Concurrently, corporate engagement is deepening, with over 30% of Fortune 500 companies maintaining verified accounts and legacy firms upgrading organizational subscriptions. NVIDIA has emerged as the strongest contributor among Big Tech companies, which are collectively creating new repositories at a rapidly increasing rate.
- China overtakes the US, now accounting for 41% of all model downloads on the Hugging Face Hub.
- The ecosystem is massively concentrated: the top 0.01% of models (200 total) get 49.6% of all downloads.
- Platform growth is explosive, with 11M users, 2M+ public models, and 500K datasets, signaling a shift to active creation.
