USA Trends and Developments Contributed by: Gregory Ulmer, James Phillips and Ryan Walton, BakerHostetler
AI Litigation Is Importing Nuclear Verdict Dynamics Into Software Cases AI litigation has rapidly converged on product liability theories because those theories map intuitively onto jury reasoning. Plaintiffs increasingly frame alleged harms not as abstract failures of governance or con - tent moderation but as foreseeable consequences of system design. Complaints now focus on architecture: how the sys - tem was built, how it was tested, what safeguards were omitted, and how it was marketed to users. Once framed this way, AI disputes begin to resemble the same kinds of cases that have driven nuclear ver - dicts in pharmaceuticals, vehicle design and industrial products. How nuclear verdict dynamics enter AI cases: two litigation vignettes To understand how this importation works in practice, it is useful to move beyond doctrine and examine how these cases are actually tried. The common thread is not whether AI formally qualifies as a product but whether the plaintiff’s narrative activates familiar moral reasoning: choice, foreseeability and preventability. Vignette One : “ You knew people would rely on it .” A mid-size technology company launches an AI-ena - bled decision-support tool marketed to small busi - nesses. The tool does not claim to replace profes - sional judgement, and the user agreement states that outputs are informational only. Internally, however, engineers and product managers debate how strongly the system’s outputs should be hedged. Clearer, more directive responses improve adoption and customer satisfaction; aggressive disclaimers reduce utility. After internal debate, the company prioritises clarity. Months later, a user relies on an AI-generated rec - ommendation in a high-stakes operational decision. The outcome is disastrous, triggering significant downstream harm. Plaintiffs do not frame the case as breach of contract or abstract AI governance failure. Instead, the complaint reads like a classic design- defect case. • The system was marketed as dependable.
willing to let categorical labels short-circuit liability analysis. What replaces formalism is a more pragmatic enquiry grounded in how the technology works from the user’s perspective. Judges are asking whether a digi - tal feature performs a function analogous to a safety mechanism, control system or product component – and whether its design choices predictably shape user behaviour. This lens naturally aligns with product liability doctrine, which has always focused on fore - seeability, alternative design and risk-utility balancing, rather than metaphysical distinctions about form. Importantly, this approach does not require courts to declare that all software or AI systems are “products”. Instead, it allows liability analysis to proceed incre - mentally, feature by feature, based on function and use. A recommendation algorithm, a default setting or an interaction loop can be evaluated on its own terms, much as a guardrail, warning label or mechani - cal control would be in a traditional product case. This modular analysis lowers the doctrinal barrier to entry for plaintiffs while preserving judicial flexibility. From a litigation perspective, this shift matters because it moves the centre of gravity away from threshold dismissal arguments and toward merits- based disputes. Defendants can no longer rely sole - ly on abstract categorisations to exit cases early. Instead, they must be prepared to explain why spe - cific design decisions were reasonable when made, how risks were assessed, and what alternatives were considered. These are questions that juries are accus - tomed to answering – and answering aggressively – in the nuclear verdict context. As courts continue to emphasise function and user experience, the consequence is predictable: more software and AI cases will survive early motions, more design choices will be scrutinised through hindsight, and more defendants will find themselves inside a product liability framework before the question of for - mal classification ever becomes dispositive.
