In our recent round-up of the top D&O stories so far this year, one of the top developments in 2026 we noted is the growing amount of AI-related D&O litigation. The AI-related litigation trend has continued to develop, as new AI-related lawsuits continue to be filed. In recent days, plaintiffs’ lawyers have filed two further AI-related securities class action lawsuits, first, against the Chinese Internet company Baidu, and, separately, against the AI-powered Internet advertising firm AppLovin. Both new lawsuits are based on AI-washing type allegations. The new lawsuit against Baidu also reflects the surging levels of securities litigation this year involving Chinese companies, as discussed further below.

Two notable securities litigation trends over the past year have been the rise of AI-related lawsuits and claims stemming from geopolitical developments, particularly U.S.-China tensions. A securities class action complaint filed on August 4, 2026, in the Southern District of New York against Alibaba Group Holding Limited (Alibaba) and the company’s CEO combines both themes in a single action (Alibaba SCA). The complaint alleges that Alibaba misled investors concerning both its AI-related activities and the risks associated with its alleged status as a “Chinese military company” under U.S. law.

A newly filed securities class action lawsuit against AI computing company Blaize Holdings is an example of how a lawsuit involving an AI company may have little or nothing to do with artificial intelligence.

The lawsuit filed against Blaize on August 4, 2026, in the Central District of California, alleges that the company misled investors about major customer contracts, improperly recognized revenue, and created a false impression of growth (Blaize SCA). While Blaize markets itself as an edge AI infrastructure company, the allegations reflect a traditional securities fraud theory rather than claims involving AI governance, AI safety, or AI-related regulation.

As discussed below, the case offers a classic securities fraud fact pattern and may offer important takeaways for D&O underwriters of AI companies.

Paul Noon

In the following guest post, Paul Noon,  OBE, Emeritus Professor of AI and Innovation and former Deputy Vice Chancellor at Coventry University, argues that UK company directors face growing legal and governance risks from AI under both the UK Companies Act and the EU AI Act, whose broad extraterritorial scope can apply even to UK companies with no EU presence if their AI systems affect people in the EU. The author also considers the implications for U.K. boards. We would like to thank Paul for allowing us to publish his article on our site. Here is his article.

Artificial intelligence-related securities litigation continues to accelerate, with plaintiffs increasingly targeting not only alleged misstatements about AI products and capabilities, but also companies’ disclosures regarding their investments in AI and the impact of those investments on business operations.  A couple of recently filed lawsuits challenge AI-related spending and capital allocation decisions, which may underscore whether growing investor scrutiny of whether management adequately disclosed the financial risks, costs, and tradeoffs associated with aggressive AI initiatives.

A securities class action filed against ZoomInfo Technologies, Inc. and certain of its directors and officers on June 25, 2026, highlights what may be the next phase of AI-related securities litigation. Unlike many earlier AI-related lawsuits, which alleged that companies overstated their AI capabilities, the Zoom complaint alleges that the company accurately described its AI initiatives but failed to disclose that AI was simultaneously disrupting its legacy business model.

If this theory gains traction, it could represent another evolution in AI-related securities litigation: from alleged AI washing to alleged underdisclosure of AI-related business risks.
