Lawmakers Open Inquiry Into PRC-Origin AI Models Deployed in US Critical Infrastructure

The House Committee on Homeland Security and the House Select Committee on the Chinese Communist Party launched a joint investigation into national security risks from Chinese-developed AI models integrated into tools used across government, defense, and critical infrastructure. Letters to Anysphere and Airbnb demand records and in-person briefings by May 20 on ties to Chinese companies including DeepSeek, Moonshot AI, ByteDance, Alibaba, and MiniMax. The committees cite an April White House OSTP memo warning that PRC-based entities are conducting industrial-scale campaigns to distill US frontier AI systems through proxy accounts. The Anysphere letter focuses on Cursor's Composer 2 model, built on Moonshot AI's open-weight Kimi K2.5, while the Airbnb letter questions the company's reported use of Alibaba's Qwen model in customer service operations.

Analysis
The joint inquiry treats Chinese AI software as a supply chain risk category on par with Huawei and ZTE hardware, a threshold that historically accelerates toward legislation once crossed. The May 20 briefing deadline and specificity of named targets (DeepSeek, Moonshot AI, ByteDance) indicate committee staff have already scoped rather than mapped. Per a single trade-press report, we assess it likely the inquiry produces a public report or legislative recommendation within six months, anchored by consistent precedent of committees following through on publicized deadlines. Airbnb's inclusion extends the regulatory surface to commercial platforms holding federal contracts. The inquiry may instead be primarily domestic competition signaling, pressuring US firms to sever Chinese AI partnerships rather than generating substantive infrastructure oversight.
