Key Findings

The report, analyzing federal AI litigation through early 2026, documents a sharp trajectory:<ref name="jdsupra-trends"/>

2022: 7 cases
2023: 19 cases
2024: 22 cases
2025: 94 cases (more than half of all cases in the dataset)
2026 (to date): 26 cases, with elevated activity expected to continue

This acceleration reflects the transition of generative AI from early adoption to widespread commercial deployment.<ref name="jdsupra-trends"/>

Defendant Concentration

OpenAI dominates the litigation landscape, appearing in 71 cases — accounting for more than 40% of all filings. This concentration reflects OpenAI's central role in the generative AI ecosystem and its visibility as a primary target for plaintiffs testing new legal theories. As with other emerging technology sectors, early market leaders bear the brunt of initial litigation waves.<ref name="jdsupra-trends"/>

Geographic Distribution

Northern District of California: 53 cases (leading district)
Southern District of New York: 23 cases
Other districts with significant but smaller volumes<ref name="jdsupra-trends"/>

This distribution reflects the technology sector's geographic concentration and these districts' established roles in complex commercial and technology disputes.

Primary Legal Issues

The analysis identifies two main categories of AI litigation:<ref name="copyright-alliance">Copyright Alliance, "Copyright Stories — February 2026"</ref>

Training data disputes: Whether the use of input data in AI model training constitutes fair use, and the nature and sourcing of such data
Product liability and deployment harms: Questions regarding design, built-in safeguards, and heightened risks posed to vulnerable groups like minors

Emerging Development: AI Hiring Liability

In Mobley v Workday Inc, a federal judge allowed age-discrimination claims under the ADEA to proceed against Workday for its AI hiring tools, rejecting arguments that the ADEA protects only employees, not job seekers. The case continues with ADEA collective action conditionally certified as of May 2025.<ref name="maynardnexsen">Maynard Nexsen, "Emerging Liability for AI-Driven Hiring Tools: Key Developments in Mobley v. Workday, Inc."</ref>

Significance

With 168 cases and rising, AI litigation is entering a phase of rapid expansion. The concentration of cases against OpenAI and in the Northern District of California suggests that early precedent-setting decisions will likely come from these venues, shaping the legal landscape for years to come.<ref name="jdsupra-trends"/>
