DHS Bans DeepSeek AI Products Over Security Concerns

The Department of Homeland Security has ordered all federal civilian agencies to remove DeepSeek AI products from their systems, a directive signed by Secretary Markwayne Mullin that took effect at the end of July. The ban covers DeepSeek's own tools as well as third-party products built on its models, citing risks of sensitive data being transferred to China and multiple security threat vectors. Agencies including Treasury, State, and Justice are affected, though the Department of Defense is exempt. Agencies can request exemptions by submitting written justifications within 60 days.

The order references the Federal Acquisition Supply Chain Security Act of 2018 and warns that DeepSeek's iOS app contains multiple critical vulnerabilities. DHS also flagged that DeepSeek collects personally identifiable information and may track users. DeepSeek, founded by Liang Wenfeng, operates servers located in China, where the legal system permits government access to private infrastructure. The company gained international attention in January 2025 with a low-cost, high-performance chatbot and released a new model called V4 in April.

China's Foreign Ministry spokesperson Mao Ning criticized the ban, calling it a politicization of technology and trade issues. Beijing vowed to protect the rights of Chinese companies. The US and China have set up a communication channel for AI incidents since September, and Presidents Trump and Xi are scheduled to meet in mid-November, where AI is expected to be a topic of discussion. South Korea also restricted DeepSeek on government computers in February 2025.

In related developments, OpenAI and Anthropic have raised concerns about DeepSeek's alleged use of model distillation to extract capabilities from their systems. Anthropic CEO Amodei recently defended the company's safety record, noting it is the only frontier AI firm to restrict sales to PRC-controlled companies. Meanwhile, Meta is preparing to issue nonvoting shares to fund its own AI investments, a strategy Alphabet used when it issued $85 billion in new stock this year. Big tech companies are pausing share buybacks as AI spending climbs.

On the earnings front, Vicor beat Q3 2026 estimates with revenue of $197.1 million, up 78.5% year over year, driven by surging AI demand. Jefferies sees upside for Spotify, forecasting a gross margin near 33.1% and potential launches of an AI remixing product tied to a Warner Music Group partnership. Infineon unveiled new AI power hardware despite sector headwinds from US-China trade tensions.
