Sources conflict on the signing date, which is listed as either June 26 or July 24, 2026. The order applies only to federal civilian agencies. Private companies, individual users and state governments fall outside it, and commercial API access for U.S. private enterprises and consumers is unaffected. Reporting says the restriction covers external vendor services that rely on DeepSeek technology, but how agencies will apply that provision to specific contracts has not been detailed.
The order turns earlier, narrower restrictions into a binding procurement rule. The Department of Commerce and the U.S. Navy had previously barred the AI service on government devices, Texas became the first state to ban it in January 2025, New York and Virginia followed, and Australia restricted it from government systems in February 2025. DHS cited data security, warning of "multiple threat vectors" and "transfer of sensitive data to the PRC," along with concerns about servers in China and malware. Separately, frontier AI companies and the federal government have accused DeepSeek of "systematically" distilling their models. For attorneys, the practical issue is contractors. Vendors selling to civilian agencies need to determine whether any product relies on DeepSeek models, update supply chain representations, and watch the Federal Register text and agency exception requests.
