As we have noted on this site, the increasing number of AI-related corporate and securities lawsuit filings is one of the most important recent developments in the world of D&O liability and insurance. Among the AI lawsuits is a particular category of claims involving allegations against AI infrastructure companies. By way of example, last week, two AI infrastructure companies were hit with securities suits alleging that the companies overstated their business opportunities  arising from providing infrastructure to support the burgeoning AI  build-out. As discussed further below, these AI infrastructure lawsuits represent their own category of AI-related suit filings.

Over the past year, market-manipulation lawsuits have become a growing feature of the securities litigation landscape, with plaintiffs targeting alleged spoofing, short-selling, pump-and-dump schemes, and other trading-related misconduct. The latest such case, filed on July 31, 2026, in the Middle District of Florida, names hedge fund Pentwater Capital Management and its founder, Matthew Halbower, as defendants (Pentwater SCA). The complaint alleges that they manipulated the market for Avis Budget Group (Avis) shares by orchestrating a short squeeze and then selling into the resulting price spike.

Unlike pump-and-dump securities suits premised on allegedly false or misleading statements, the Pentwater SCA is based on the defendants’ trading activity itself. The lawsuit arguably represents an example of a growing trend in market-manipulation-related securities class action litigation while underscoring an increasingly important issue for D&O underwriters: securities litigation risk arising not from disclosure deficiencies, but from market-structure and trading-related factors capable of driving extreme stock-price volatility.

The securities class action lawsuit filed against Intuit, Inc. on August 17, 2026, represents another notable development in one of the most significant securities litigation trends of the year. According to our count, the Intuit case is the 20th AI-related securities class action filed in 2026, underscoring the continued evolution of AI-related litigation beyond traditional allegations of AI-washing and overstated artificial intelligence capabilities.

Similar to the securities class action filed against ZoomInfo Technologies on July 13, 2026, the complaint against Intuit alleges that, while the company promoted the benefits of artificial intelligence, it failed to disclose the extent to which AI was simultaneously creating competitive pressures for key parts of its business.

A copy of the complaint filed against Intuit can be found here.

In the following guest post, Nessim Mezrahi and Stephen Sigrist present their view that U.S. securities litigation risk is increasing significantly, driven by geopolitical instability and weakening investor confidence in the AI investment proposition, and that growing market capitalization losses, increased shareholder scrutiny, and the potential for an AI-related market correction are creating heightened securities litigation exposure. Nessim Mezrahi is co-founder and CEO, and Stephen Sigrist is a senior vice president, at SAR LLC. Our thanks to Nessim and Stephen for allowing us to publish their article on our site.

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.

In the following guest post, Glenn Oborne, Director at Ingen Partners, a specialist governance recruitment and consultancy firm, argues that the greatest risk of a prolonged governance vacancy is not disruption of board administration, but the loss of continuity, oversight, and accountability that connects director questions, management commitments, and emerging warning signs across time. Even when meetings, reports, and compliance processes continue smoothly, fragmented responsibility can make it harder for boards to identify developing issues, demonstrate effective oversight, and defend their decision-making if later scrutinized by regulators or shareholders. Our thanks to Glenn for allowing us to publish his article on our site. Here is Glenn’s article.

A frequently recurring coverage issue litigated in Delaware courts is the treatment of related claims and the consequences that flow from a determination that multiple proceedings are related. A recent Delaware Superior Court decision revisits those issues, this time in a dispute involving an insurer’s reliance on related-claims language in a policy retention provision to deny coverage for a derivative action.

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.
