The US Department of Homeland Security (DHS) ordered on Monday, October 19, 2026, the exclusion and removal of DeepSeek products and third-party services that use its models from the information technology systems of civilian federal agencies. The measure also bars the Chinese company from participating in federal contracts.
What happened?
According to reports from Reuters, Bloomberg, and The Verge, the order — posted for public inspection in the Federal Register and scheduled for formal publication on October 20 — was issued under the Federal Acquisition Supply Chain Security Act of 2018. DHS states that DeepSeek models present "multiple threat vectors" and that use may result in the transfer of sensitive data to the People's Republic of China.
The agency also mentions risks that the models may contain malware or security vulnerabilities and produce actionable intelligence on US persons and agencies. The order covers civilian executive branch agencies, excluding national security systems and sensitive compartmented information systems.
The measure comes days after the release of DeepSeek V4.1-Flash-1017, an open-weight model that the Chinese company presented as faster and more efficient. Previously, agencies such as Commerce and the Navy, as well as some states, had already restricted DeepSeek use on government devices.
Why it matters
The formal ban expands US restrictions on Chinese open-weight AI models that gained rapid adoption due to cost and performance. For developers, companies, and the agent ecosystem that rely on models like DeepSeek's, the prohibition on federal procurement and civilian systems may influence usage policies and supply chain due diligence.
As of the reports, the Chinese Embassy in Washington had not publicly commented on the order, according to Reuters. The episode reinforces the geopolitical dimension of AI model competition and the tension between access to efficient models and data security concerns.
