The Trump administration's decision to allow Nvidia's H20 chips back into China has triggered a surge of urgent orders from major Chinese cloud providers, reviving not only Nvidia's outlook but also lifting sentiment across the AI semiconductor ecosystem.

In April 2025, the U.S. expanded restrictions to include the Nvidia H20 chip, a China-specific version designed to comply with earlier export rules.

Shares of Nvidia closed at a record $170.70 Tuesday following news the chipmaker expects to resume exports of its advanced H20 GPU to China.
