Beijing needs to send Nvidia Chief Executive Jensen Huang a thank-you note. Nvidia and fellow chip maker AMD are so hell-bent on selling to China that they even agreed to be taxed 15% by the U.S. government on their China sales. Washington gets tax revenue; China gets free lobbying against export restrictions.

Nvidia's CEO has sold millions of dollars worth of his company's shares this year, and he's not done selling yet.

Nvidia had to write off $4.5 billion due to the ban in Q1, with an additional $8 billion hit expected in Q2, while AMD reported an $800 million loss in Q2.
