At a San Francisco AI Summit on July 24, local time, Silicon Valley split over U.S. regulations on Chinese AI and semiconductor technologies. In the AI sector, conflict emerged over potential "open-source AI controls." On July 24, 25 U.S. big tech firms including NVIDIA, Microsoft, Meta, and Palantir issued a joint letter urging cautious policy, stating "Premature regulation of open-weight AI models could stifle competition and drive innovation overseas." NVIDIA CEO Jensen Huang and Microsoft CEO Satya Nadella publicly endorsed the letter. Conversely, closed-model AI leaders OpenAI and Anthropic opposed the move, arguing "Chinese firms are inappropriately collecting data from U.S. models to narrow the technology gap" and that national-level controls are necessary. In semiconductors, U.S. memory firms are fiercely opposing Apple’s request to the government to import Chinese-made memory chips amid soaring prices. Critics argue the U.S. industry and government are being divided by internal strife.
