Nuclear Verdicts Climbed 40.7% in 2025 as Report Ties Growth to Eroding Tort Reform
A new annual study of large jury awards has recorded the steepest year of nuclear verdict activity since 2009, and it places the erosion of tort reform — including rules governing third-party litigation funding — among the forces driving the increase.
As reported by Insurance Journal, the latest edition of Marathon Strategies' *Corporate Verdicts Go Thermonuclear* report counted nearly 200 verdicts of $10 million or more against corporate defendants in 2025, a 40.7% rise over 2024 and the highest total in sixteen years. Those awards totalled $25.6 billion. Forty of them cleared $100 million, the threshold Marathon uses for a "thermonuclear" verdict, and four exceeded $1 billion.
The spread across the economy widened as well. The report identified nuclear verdicts in 68 industries, up from 55 the previous year and 48 the year before that. Product liability accounted for 29 verdicts worth roughly $12 billion, while the insurance sector recorded five verdicts totalling $390 million. Texas, California, Florida and Maryland saw the heaviest activity.
Marathon attributes the trend to a combination of factors, stating that its research "identified corporate mistrust, social pessimism, erosion of tort reform, and public desensitization to large numbers as among the most important."
The reference to tort reform is notable given the pace of state-level legislative activity. Eight states — Arkansas, Georgia, Kansas, Louisiana, Missouri, Montana, Oklahoma and South Carolina — enacted tort reform measures in 2025, and those packages included both damages caps and expanded disclosure obligations for third-party litigation funders.
The findings are likely to be cited on both sides of the funding debate, with defence-side advocates pointing to verdict growth as evidence that disclosure rules are needed, and funders noting that the report identifies broader social and economic drivers rather than isolating litigation finance as the cause.
