Chinese AI Stars Leave Silicon Valley for Opportunities at Home

The United States has long turned its universities, deep venture-capital pools and technology giants into a magnet for global AI talent, with Chinese-born researchers playing an outsized role in frontier work. That advantage is being tested as China’s domestic model developers, funding base and vast commercial market mature. Tighter U.S. visa rules and national-security scrutiny add friction, while founders increasingly see Chinese technology hubs as places where they can build companies, not merely supply talent to Silicon Valley.

Moonshot AI co-founder Yang Zhilin has become an emblem of that shift. After Tsinghua University, he completed a Carnegie Mellon University doctorate in 2019, held research roles at Google Brain and Meta, and returned to China despite interest from Apple. On July 16, 2026, Moonshot released Kimi K3, a 2.8-trillion-parameter open-weight model approaching leading U.S. systems on key tests. The 2023-founded startup was seeking about $2 billion at a roughly $30 billion valuation ahead of a possible Hong Kong listing.
