According to @StockMKTNewz, CNBC reported that NVIDIA (NVDA) refuted a report claiming China’s DeepSeek is using its Blackwell AI chips, which CNBC characterized as banned in China (CNBC). NVIDIA’s denial addresses the compliance concern raised in the CNBC item, signaling the company disputes any prohibited use in China (CNBC). The U.S. Department of Commerce’s Bureau of Industry and Security restricts shipments of advanced AI accelerators to China under updated export rules, which is the regulatory backdrop referenced in media coverage of banned high-performance chips (U.S. Department of Commerce BIS). CNBC did not cite any direct cryptocurrency market impact tied to this headline (CNBC).
