It is unclear how many licenses may have been issued, which companies Nvidia is allowed to ship the H20s to, and the value of the shipments allowed.

The export restrictions on the H20 chip are expected to have a major impact on NVIDIA's sales. The company has warned that these curbs will cut its revenue by $8 billion in the July quarter. In April, NVIDIA had predicted a $5.5 billion charge due to these restrictions but later revised it down by $1 billion as some materials could be reused.

The U.S. Department of Justice (DOJ) said on Tuesday that two Chinese nationals have been arrested for their alleged involvement in illegally shipping "tens of millions of dollars" worth of high-performance AI chips to China.
