Blackwell chips

Nvidia denied reports that Chinese AI startup DeepSeek smuggled its advanced Blackwell chips, which the U.S. has banned from export to protect a strategic AI lead. While Nvidia investigates all leads, it says there’s no evidence of “phantom data centers.” President Trump has proposed allowing H200 chips to “approved” Chinese customers with a 25% U.S. revenue share, sparking bipartisan debate over technology‑transfer risks. DeepSeek’s low‑cost R1 model has risen quickly, highlighting competitive pressure on Western AI firms and the uncertainty of export controls.
