Anthropic has notified the White House that Chinese tech giant Alibaba attempted to illicitly access its Claude AI models, according to reports. The company flagged what it described as an effort to harvest U.S. artificial intelligence capabilities. The alert has intensified scrutiny of cross-border technology transfers.

The incident underscores growing tensions between Washington and Beijing over advanced AI development. U.S. regulators have increasingly focused on preventing adversaries from gaining access to sensitive AI technologies. Alibaba's alleged actions could accelerate policy debates on export controls and technology security.

Alibaba shares slid further following the report, extending recent declines. The company has not publicly responded to the allegations. Investor's Business Daily noted that the attempt was characterized as illicit by Anthropic.

The episode may heighten calls for stricter oversight of foreign entities accessing U.S. AI platforms. It also risks escalating trade friction between the two largest economies. Policymakers are likely to examine whether current safeguards are adequate.

Some analysts caution that details remain sparse, and Alibaba has denied similar allegations in the past. The full scope of the alleged attempt is still unclear.
