NVDA is trading 3.7% down today at $226.99 after reports surfaced that Beijing blocked purchases of its H200 AI chips, reversing a recent rally fueled by China demand hopes.

  • The reported block comes despite U.S. authorities previously approving the sale of the H200 chips to Chinese customers.
  • The decline is being amplified by a broader tech sector selloff that has pushed the Nasdaq down over 1% ahead of Nvidia's May 20 earnings report.
