US Accuses Alibaba and DeepSeek of Systematically Siphoning American AI Knowledge
U.S. security agencies have accused leading Chinese AI companies—including DeepSeek, Moonshot AI (Kimi), and Alibaba—of systematically extracting proprietary knowledge from American firms, according to Bloomberg. The allegations mark a shift from general espionage warnings to named accusations against developers central to China's AI push. Officials also warned Silicon Valley developers to protect their work, suggesting intelligence agencies believe extraction may be ongoing and sophisticated. The move aligns with broader U.S. efforts to limit China's advanced AI access through export controls and sharpens tension between open distribution and national-security scrutiny of model provenance. Bloomberg's reporting does not cite technical evidence or specific extraction methods, so the scale and mechanics of the alleged activity remain unverified in public disclosures.
US Accuses Alibaba and DeepSeek of Systematically Siphoning American AI Knowledge
US security agencies have accused China’s top AI companies, including DeepSeek and Kimi maker Moonshot AI, of systematically extracting proprietary knowledge from American firms. The agencies also warned Silicon Valley developers to protect their work, according to Bloomberg reporting.
Key takeaway
Named U.S. accusations against DeepSeek, Moonshot AI, and Alibaba signal a policy turn that treats model access as a security perimeter, not just an IP concern.
What happened
According to Bloomberg, U.S. security agencies have accused China's top AI companies, including DeepSeek and Kimi maker Moonshot AI, of systematically extracting proprietary knowledge from American firms.
The agencies also named Alibaba in accusations of siphoning proprietary AI models and warned Silicon Valley developers to protect their work, suggesting officials believe the activity is ongoing and sophisticated.

The warning to Silicon Valley developers suggests intelligence agencies believe this extraction is ongoing and sophisticated.
Why it matters
Operators releasing APIs or open weights may face tighter access controls, legal exposure, and pressure to document provenance as U.S.-China AI competition intensifies.
Limits and uncertainties
Bloomberg's excerpt does not include technical evidence or specific examples of how the alleged extraction occurred, limiting assessment of scale and methods.
The reporting does not address whether some activity could involve legitimate open-source distillation or public data scraping rather than proprietary theft.
Practical implications
Treat public APIs and model releases as potential extraction targets and review access controls, rate limits, and monitoring.
Document model provenance and data lineage before distribution to reduce legal and compliance risk if scrutiny tightens.
What to watch
Whether U.S. agencies publish technical evidence or enforcement actions tied to the named firms.
Changes to API access policies, export controls, or developer guidance from U.S. security agencies.
