Open-weight AI companies are the Valley’s hottest acquisition targets

Nvidia is poised to acquire Hugging Face for $13 billion, targeting the premier open-weight AI model hub that lets developers share and benchmark LLMs independent of major labs. Recent deals—Nvidia’s $6 billion purchase of Poolside and Stripe’s $7 billion buy of OpenRouter—highlight a surge of capital into open-weight ecosystems, which currently serve about 6% of companies and 2% of engineers for high-volume, repeatable inference tasks.
